Intensive voice treatment (LSVT) for patients with Parkinson's disease: a 2 year follow up. (1/233)
OBJECTIVES: To assess long term (24 months) effects of the Lee Silverman voice treatment (LSVT), a method designed to improve vocal function in patients with Parkinson's disease. METHODS: Thirty three patients with idiopathic Parkinson's disease were stratified and randomly assigned to two treatment groups. One group received the LSVT, which emphasises high phonatory-respiratory effort. The other group received respiratory therapy (RET), which emphasises high respiratory effort alone. Patients in both treatment groups sustained vowel phonation, read a passage, and produced a monologue under identical conditions before, immediately after, and 24 months after speech treatment. Change in vocal function was measured by means of acoustic analyses of voice loudness (measured as sound pressure level, or SPL) and inflection in voice fundamental frequency (measured in terms of semitone standard deviation, or STSD). RESULTS: The LSVT was significantly more effective than the RET in improving (increasing) SPL and STSD immediately post-treatment and maintaining those improvements at 2 year follow up. CONCLUSIONS: The findings provide evidence for the efficacy of the LSVT as well as the long term maintenance of these effects in the treatment of voice and speech disorders in patients with idiopathic Parkinson's disease. (+info)Is voice therapy an effective treatment for dysphonia? A randomised controlled trial. (2/233)
OBJECTIVES: To assess the overall efficacy of voice therapy for dysphonia. DESIGN: Single blind randomised controlled trial. SETTING: Outpatient clinic in a teaching hospital. PARTICIPANTS: 204 outpatients aged 17-87 with a primary symptom of persistent hoarseness for at least two months. INTERVENTIONS: After baseline assessments, patients were randomised to six weeks of either voice therapy or no treatment. Assessments were repeated at six weeks on the 145 (71%) patients who continued to this stage and at 12-14 weeks on the 133 (65%) patients who completed the study. The assessments at the three time points for the 70 patients who completed treatment and the 63 patients in the group given no treatment were compared. MAIN OUTCOME MEASURES: Ratings of laryngeal features, Buffalo voice profile, amplitude and pitch perturbation, voice profile questionnaire, hospital anxiety and depression scale, clinical interview schedule, SF-36. RESULTS: Voice therapy improved voice quality as assessed by rating by patients (P=0.001) and rating by observer (P<0.001). The treatment effects for these two outcomes were 4.1 (95% confidence interval 1.7 to 6.6) points and 0.82 (0.50 to 1.13) points. Amplitude perturbation showed improvement at six weeks (P=0.005) but not on completion of the study. Patients with dysphonia had appreciable psychological distress and lower quality of life than controls, but voice therapy had no significant impact on either of these variables. CONCLUSION: Voice therapy is effective in improving voice quality as assessed by self rated and observer rated methods. (+info)Swallowing and voice effects of Lee Silverman Voice Treatment (LSVT): a pilot study. (3/233)
OBJECTIVE: To define the effects of Lee Silverman Voice Treatment (LSVT on swallowing and voice in eight patients with idiopathic Parkinson's disease. METHODS: Each patient received a modified barium swallow (MBS) in addition to voice recording before and after 1 month of LSVT. Swallowing motility disorders were defined and temporal measures of the swallow were completed from the MBS. Voice evaluation included measures of vocal intensity, fundamental frequency, and the patient's perception of speech change. RESULTS: before LSVT, the most prevalent swallowing motility disorders were oral phase problems including reduced tongue control and strength. Reduced tongue base retraction resulting in residue in the vallecula was the most common disorder in the pharyngeal stage of the swallow. Oral transit time (OTT) and pharyngeal transit time (PTT) were prolonged. After LSVT, there was an overall 51% reduction in the number of swallowing motility disorders. Some temporal measures of swallowing were also significantly reduced as was the approximate amount of oral residue after 3 ml and 5 ml liquid swallows. Voice changes after LSVT included a significant increase in vocal intensity during sustained vowel phonation as well as during reading. CONCLUSIONS: LSVT seemingly improved neuromuscular control of the entire upper aerodigestive tract, improving oral tongue and tongue base function during the oral and pharyngeal phases of swallowing as well as improving vocal intensity. (+info)Fear recognition in the voice is modulated by unconsciously recognized facial expressions but not by unconsciously recognized affective pictures. (4/233)
Multisensory integration is a powerful mechanism for increasing adaptive responses, as illustrated by binding of fear expressed in a face with fear present in a voice. To understand the role of awareness in intersensory integration of affective information we studied multisensory integration under conditions of conscious and nonconscious processing of the visual component of an audiovisual stimulus pair. Auditory-event-related potentials were measured in two patients (GY and DB) who were unable to perceive visual stimuli consciously because of striate cortex damage. To explore the role of conscious vision of audiovisual pairing, we also compared audiovisual integration in either naturalistic pairings (a facial expression paired with an emotional voice) or semantic pairings (an emotional picture paired with the same voice). We studied the hypothesis that semantic pairings, unlike naturalistic pairings, might require mediation by intact visual cortex and possibly by feedback to primary cortex from higher cognitive processes. Our results indicate that presenting incongruent visual affective information together with the voice translates as an amplitude decrease of auditory-event-related potentials. This effect obtains for both naturalistic and semantic pairings in the intact field, but is restricted to the naturalistic pairings in the blind field. (+info)Truth and character: sources that older adults can remember. (5/233)
Are age differences in source memory inevitable? The two experiments reported here examined the hypothesis that the type of source information being tested mediates the magnitude of age differences in source memory. In these studies, participants listened to statements made by two different speakers. We compared younger and older adults' source memory in a traditional perceptual source task (memory for voice) and in two affective, conceptually based source tasks (truth of the statements, character of a person in a photo). In both studies, the perceptual and conceptual source information were conveyed in the same manner, as one speaker was associated with one type of information (e.g., female voice speaks truth). Age differences were robust for decisions regarding who said each statement but were negligible or truth or character decisions. These findings are provocative because they suggest that the type of information can influence age-related patterns of performance for source-conveyed information. (+info)Prospective functional voice assessment in patients undergoing thyroid surgery. (6/233)
OBJECTIVE: To analyze voice function before and after thyroidectomy for patients with normal preoperative voice using a standardized multidimensional voice assessment protocol. SUMMARY BACKGROUND DATA: The natural history of post-thyroidectomy voice disturbances for patients with preserved laryngeal nerve function has not been systematically studied and characterized with the intent of using the data for postoperative voice rehabilitation. METHODS: During a prospective single-arm study, patients with normal voice underwent functional voice testing using a standardized voice grading scale and a battery of acoustic, aerodynamic, glottographic, and videostroboscopic tests before, 1 week after, and 3 months after thyroidectomy. Differences in observed sample means were evaluated using analysis of covariance or t test; categorical data was analyzed using the Fisher exact or chi-square test. RESULTS: Fifty-four patients were enrolled; 50 and 46 were evaluable at 1 week and 3 months, respectively. No patient developed recurrent laryngeal nerve injury; one had superior laryngeal nerve injury. Fifteen (30%) patients reported early subjective voice change and seven (14%) reported late (3-month) subjective voice change. Forty-two (84%) patients had significant objective change in at least one voice parameter. Six (12%) had significant alterations in more than three voice measures, of which four (67%) were symptomatic, whereas 25% with three or fewer objective changes had symptoms. Patients with persistent voice change at 3 months had an increased likelihood of multiple (more than three) early objective changes (43% vs. 7%). Early maximum phonational frequency range and vocal jitter changes from baseline were significantly associated with voice symptoms at 3 months. CONCLUSIONS: Early vocal symptoms are common following thyroidectomy and persist in 14% of patients. Multiple (more than three) objective voice changes correlate with early and late postoperative symptoms. Alterations in maximum phonational frequency range and vocal jitter predict late perceived vocal changes. Factors other than laryngeal nerve injury appear to alter post-thyroidectomy voice. The variability of patient symptoms underscores the importance of understanding the physiology of dysphonia. (+info)Quantitative analysis of professionally trained versus untrained voices. (7/233)
The aim of this study was to compare healthy trained and untrained voices as well as healthy and dysphonic trained voices in adults using combined voice range profile and aerodynamic tests, to define the normal range limiting values of quantitative voice parameters and to select the most informative quantitative voice parameters for separation between healthy and dysphonic trained voices. Three groups of persons were evaluated. One hundred eighty six healthy volunteers were divided into two groups according to voice training: non-professional speakers group consisted of 106 untrained voices persons (36 males and 70 females) and professional speakers group--of 80 trained voices persons (21 males and 59 females). Clinical group consisted of 103 dysphonic professional speakers (23 males and 80 females) with various voice disorders. Eighteen quantitative voice parameters from combined voice range profile (VRP) test were analyzed: 8 of voice range profile, 8 of speaking voice, overall vocal dysfunction degree and coefficient of sound, and aerodynamic maximum phonation time. Analysis showed that healthy professional speakers demonstrated expanded vocal abilities in comparison to healthy non-professional speakers. Quantitative voice range profile parameters- pitch range, high frequency limit, area of high frequencies and coefficient of sound differed significantly between healthy professional and non-professional voices, and were more informative than speaking voice or aerodynamic parameters in showing the voice training. Logistic stepwise regression revealed that VRP area in high frequencies was sufficient to discriminate between healthy and dysphonic professional speakers for male subjects (overall discrimination accuracy--81.8%) and combination of three quantitative parameters (VRP high frequency limit, maximum voice intensity and slope of speaking curve) for female subjects (overall model discrimination accuracy--75.4%). We concluded that quantitative voice assessment with selected parameters might be useful for evaluation of voice education for healthy professional speakers as well as for detection of vocal dysfunction and evaluation of rehabilitation effect in dysphonic professionals. (+info)Diagnostic test with omeprazole in patients with posterior laryngitis. (8/233)
The aim of the study was to evaluate the merit of empiric omeprazole therapy in patients with suspected laryngopharyngeal reflux (LPR), to determine the optimal dose and duration of diagnostic test, to compare the diagnostic value of upper gastrointestinal (GI) endoscopy and omeprazole test (OT). One hundred out-patients with posterior laryngitis and more than one atypical symptom of LPR, aged 14-68 years were treated with omeprazole for 4 weeks (clinical group). According to received omeprazole dose (20 mg, 40 mg, > 40 mg), three clinical subgroups were selected. Twenty patients treated only with life style modifications and diet composed dietary group. At the entry to the study, a symptom questionnaire (5 laryngeal and 3 esophageal scored from 0 to 3 points), well being in general (W-B(VAS) on 100-mm VAS scale), videolaryngoscopy, upper endoscopy, and voice assessment (4 voice range profile parameters and overall vocal dysfunction degree (VDD)) were completed. Total symptom index (TSI) was calculated multiplying sum of symptoms severity score by number of presented symptoms. Normal values of efficacy parameters were obtained from 113 healthy voice subjects (control group). Patients were evaluated twice during the treatment: after 1-2 weeks and after 4-5 weeks. Patients were confirmed as responders, if TSI improved at least 50%, and patients were satisfied with results. According to our data, the 1st control assessment showed significant improvement on symptoms, laryngoscopy scores, VDD, and W-B(VAS) only for clinical group patients (p<0.05). Responders rate also was advantageous for the clinical group patients in comparison to the dietary group (36.0% vs. 15%). The second control assessment showed significantly better results for the clinical group patients in comparison to the 1st (p<0.05 2nd vs. the 1st). Sixty five percent of them (65/100) were classified as responders (p<0.05). The better results were in patients receiving omeprazole more than 20 mg daily. Erosive esophagitis during upper GI endoscopy was found for 21.0% (21/100) clinical group patients, 18 of them were responders to omeprazole 4-week test (accuracy of OT with regard to confirmed diagnosis with upper endoscopy was 85.7%). At week 4, efficacy parameters were not in normal range. We concluded that short-term treatment with omeprazole might be useful in confirming the clinically based diagnosis of laryngopharyngeal reflux. (+info)Voice quality, in the context of medicine and particularly in otolaryngology (ear, nose, and throat medicine), refers to the characteristic sound of an individual's voice that can be influenced by various factors. These factors include the vocal fold vibration, respiratory support, articulation, and any underlying medical conditions.
A change in voice quality might indicate a problem with the vocal folds or surrounding structures, neurological issues affecting the nerves that control vocal fold movement, or other medical conditions. Examples of terms used to describe voice quality include breathy, hoarse, rough, strained, or tense. A detailed analysis of voice quality is often part of a speech-language pathologist's assessment and can help in diagnosing and managing various voice disorders.
Voice disorders are conditions that affect the quality, pitch, or volume of a person's voice. These disorders can result from damage to or abnormalities in the vocal cords, which are the small bands of muscle located in the larynx (voice box) that vibrate to produce sound.
There are several types of voice disorders, including:
1. Vocal cord dysfunction: This occurs when the vocal cords do not open and close properly, resulting in a weak or breathy voice.
2. Vocal cord nodules: These are small growths that form on the vocal cords as a result of excessive use or misuse of the voice, such as from shouting or singing too loudly.
3. Vocal cord polyps: These are similar to nodules but are usually larger and can cause more significant changes in the voice.
4. Laryngitis: This is an inflammation of the vocal cords that can result from a viral infection, overuse, or exposure to irritants such as smoke.
5. Muscle tension dysphonia: This occurs when the muscles around the larynx become tense and constricted, leading to voice changes.
6. Paradoxical vocal fold movement: This is a condition in which the vocal cords close when they should be open, causing breathing difficulties and a weak or breathy voice.
7. Spasmodic dysphonia: This is a neurological disorder that causes involuntary spasms of the vocal cords, resulting in voice breaks and difficulty speaking.
Voice disorders can cause significant impairment in communication, social interactions, and quality of life. Treatment may include voice therapy, medication, or surgery, depending on the underlying cause of the disorder.
In medical terms, the term "voice" refers to the sound produced by vibration of the vocal cords caused by air passing out from the lungs during speech, singing, or breathing. It is a complex process that involves coordination between respiratory, phonatory, and articulatory systems. Any damage or disorder in these systems can affect the quality, pitch, loudness, and flexibility of the voice.
The medical field dealing with voice disorders is called Phoniatrics or Voice Medicine. Voice disorders can present as hoarseness, breathiness, roughness, strain, weakness, or a complete loss of voice, which can significantly impact communication, social interaction, and quality of life.
Dysphonia is a medical term that refers to difficulty or discomfort in producing sounds or speaking, often characterized by hoarseness, roughness, breathiness, strain, or weakness in the voice. It can be caused by various conditions such as vocal fold nodules, polyps, inflammation, neurological disorders, or injuries to the vocal cords. Dysphonia can affect people of all ages and may impact their ability to communicate effectively, causing social, professional, and emotional challenges. Treatment for dysphonia depends on the underlying cause and may include voice therapy, medication, surgery, or lifestyle modifications.
The glottis is a medical term that refers to the opening between the vocal cords (the ligaments in the larynx that produce sound when air passes through them during speech) in the human throat or larynx. It is an important structure for breathing, swallowing, and producing sounds or speech. The glottis opens during inhalation to allow air into the lungs and closes during swallowing to prevent food or liquids from entering the trachea (windpipe) and lungs.
Speech acoustics is a subfield of acoustic phonetics that deals with the physical properties of speech sounds, such as frequency, amplitude, and duration. It involves the study of how these properties are produced by the vocal tract and perceived by the human ear. Speech acousticians use various techniques to analyze and measure the acoustic signals produced during speech, including spectral analysis, formant tracking, and pitch extraction. This information is used in a variety of applications, such as speech recognition, speaker identification, and hearing aid design.
Phonation is the process of sound production in speech, singing, or crying. It involves the vibration of the vocal folds (also known as the vocal cords) in the larynx, which is located in the neck. When air from the lungs passes through the vibrating vocal folds, it causes them to vibrate and produce sound waves. These sound waves are then shaped into speech sounds by the articulatory structures of the mouth, nose, and throat.
Phonation is a critical component of human communication and is used in various forms of verbal expression, such as speaking, singing, and shouting. It requires precise control of the muscles that regulate the tension, mass, and length of the vocal folds, as well as the air pressure and flow from the lungs. Dysfunction in phonation can result in voice disorders, such as hoarseness, breathiness, or loss of voice.
Vocal cords, also known as vocal folds, are specialized bands of muscle, membrane, and connective tissue located within the larynx (voice box). They are essential for speech, singing, and other sounds produced by the human voice. The vocal cords vibrate when air from the lungs is passed through them, creating sound waves that vary in pitch and volume based on the tension, length, and mass of the vocal cords. These sound waves are then further modified by the resonance chambers of the throat, nose, and mouth to produce speech and other vocalizations.
Hoarseness is a condition characterized by an abnormal change in the quality of voice, making it sound rough, breathy, strained, or weak. Medically, it's described as a disorder of phonation, which is the process of producing sound by vibrating the vocal cords in the larynx (voice box). Hoarseness can be caused by various factors, such as inflammation, irritation, or injury to the vocal cords, and may result in symptoms like altered voice pitch, volume, and clarity. It's essential to consult a healthcare professional if hoarseness persists for more than two weeks, especially if it's accompanied by other concerning symptoms like difficulty swallowing or breathing.
"Voice training" is not a term that has a specific medical definition in the field of otolaryngology (ear, nose, and throat medicine) or speech-language pathology. However, voice training generally refers to the process of developing and improving one's vocal skills through various exercises and techniques. This can include training in breath control, pitch, volume, resonance, articulation, and interpretation, among other aspects of vocal production. Voice training is often used to help individuals with voice disorders or professionals such as singers and actors to optimize their vocal abilities. In a medical context, voice training may be recommended or overseen by a speech-language pathologist as part of the treatment plan for a voice disorder.
Laryngoscopy is a medical procedure that involves the examination of the larynx, which is the upper part of the windpipe (trachea), and the vocal cords using a specialized instrument called a laryngoscope. The laryngoscope is inserted through the mouth or nose to provide a clear view of the larynx and surrounding structures. This procedure can be performed for diagnostic purposes, such as identifying abnormalities like growths, inflammation, or injuries, or for therapeutic reasons, such as removing foreign objects or taking tissue samples for biopsy. There are different types of laryngoscopes and techniques used depending on the reason for the examination and the patient's specific needs.
Stroboscopy is a medical examination technique used primarily for the evaluation of voice and swallowing disorders. It involves the use of a strobe light that flickers at a rate equal to or close to the vibration rate of the vocal folds (vocal cords). This allows the examiner to visualize the movement of the vocal folds in slow motion, which can help identify any abnormalities in their movement or structure.
During the procedure, a thin, flexible tube called a stroboscope is inserted through the nose and into the throat. The strobe light is then activated, and the examiner observes the vibration of the vocal folds using an attached camera and video monitor. This technique can help diagnose conditions such as vocal fold nodules, polyps, paralysis, and other disorders that affect voice production.
It's important to note that stroboscopy should be performed by a trained healthcare professional, such as an otolaryngologist (ear, nose, and throat specialist) or speech-language pathologist, who has experience in evaluating voice and swallowing disorders.
A laryngectomy is a surgical procedure that involves the removal of the larynx, also known as the voice box. This is typically performed in cases of advanced laryngeal cancer or other severe diseases of the larynx. After the surgery, the patient will have a permanent stoma (opening) in the neck to allow for breathing. The ability to speak after a total laryngectomy can be restored through various methods such as esophageal speech, tracheoesophageal puncture with a voice prosthesis, or electronic devices.
Vocal cord paralysis is a medical condition characterized by the inability of one or both vocal cords to move or function properly due to nerve damage or disruption. The vocal cords are two bands of muscle located in the larynx (voice box) that vibrate to produce sound during speech, singing, and breathing. When the nerves that control the vocal cord movements are damaged or not functioning correctly, the vocal cords may become paralyzed or weakened, leading to voice changes, breathing difficulties, and other symptoms.
The causes of vocal cord paralysis can vary, including neurological disorders, trauma, tumors, surgery, or infections. The diagnosis typically involves a physical examination, including a laryngoscopy, to assess the movement and function of the vocal cords. Treatment options may include voice therapy, surgical procedures, or other interventions to improve voice quality and breathing functions.
Sound spectrography, also known as voice spectrography, is a diagnostic procedure in which a person's speech sounds are analyzed and displayed as a visual pattern called a spectrogram. This test is used to evaluate voice disorders, speech disorders, and hearing problems. It can help identify patterns of sound production and reveal any abnormalities in the vocal tract or hearing mechanism.
During the test, a person is asked to produce specific sounds or sentences, which are then recorded and analyzed by a computer program. The program breaks down the sound waves into their individual frequencies and amplitudes, and displays them as a series of horizontal lines on a graph. The resulting spectrogram shows how the frequencies and amplitudes change over time, providing valuable information about the person's speech patterns and any underlying problems.
Sound spectrography is a useful tool for diagnosing and treating voice and speech disorders, as well as for researching the acoustic properties of human speech. It can also be used to evaluate hearing aids and other assistive listening devices, and to assess the effectiveness of various treatments for hearing loss and other auditory disorders.
Quality of Life (QOL) is a broad, multidimensional concept that usually includes an individual's physical health, psychological state, level of independence, social relationships, personal beliefs, and their relationship to salient features of their environment. It reflects the impact of disease and treatment on a patient's overall well-being and ability to function in daily life.
The World Health Organization (WHO) defines QOL as "an individual's perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns." It is a subjective concept, meaning it can vary greatly from person to person.
In healthcare, QOL is often used as an outcome measure in clinical trials and other research studies to assess the impact of interventions or treatments on overall patient well-being.
The laryngeal mucosa is the mucous membrane that lines the interior surface of the larynx, also known as the voice box. This mucous membrane is composed of epithelial cells and underlying connective tissue, and it plays a crucial role in protecting the underlying tissues of the larynx from damage, infection, and other environmental insults.
The laryngeal mucosa is continuous with the respiratory mucosa that lines the trachea and bronchi, and it contains numerous mucus-secreting glands and cilia that help to trap and remove inhaled particles and microorganisms. Additionally, the laryngeal mucosa is richly innervated with sensory nerve endings that detect changes in temperature, pressure, and other stimuli, allowing for the regulation of breathing, swallowing, and voice production.
Damage to the laryngeal mucosa can occur as a result of various factors, including irritants, infection, inflammation, and trauma, and may lead to symptoms such as pain, swelling, difficulty swallowing, and changes in voice quality.
Psychoacoustics is a branch of psychophysics that deals with the study of the psychological and physiological responses to sound. It involves understanding how people perceive, interpret, and react to different sounds, including speech, music, and environmental noises. This field combines knowledge from various areas such as psychology, acoustics, physics, and engineering to investigate the relationship between physical sound characteristics and human perception. Research in psychoacoustics has applications in fields like hearing aid design, noise control, music perception, and communication systems.
Laryngeal neoplasms refer to abnormal growths or tumors in the larynx, also known as the voice box. These growths can be benign (non-cancerous) or malignant (cancerous). Laryngeal neoplasms can affect any part of the larynx, including the vocal cords, epiglottis, and the area around the vocal cords called the ventricle.
Benign laryngeal neoplasms may include papillomas, hemangiomas, or polyps. Malignant laryngeal neoplasms are typically squamous cell carcinomas, which account for more than 95% of all malignant laryngeal tumors. Other types of malignant laryngeal neoplasms include adenocarcinoma, sarcoma, and lymphoma.
Risk factors for developing laryngeal neoplasms include smoking, alcohol consumption, exposure to industrial chemicals, and a history of acid reflux. Symptoms may include hoarseness, difficulty swallowing, sore throat, ear pain, or a lump in the neck. Treatment options depend on the type, size, location, and stage of the neoplasm but may include surgery, radiation therapy, chemotherapy, or a combination of these treatments.
"Quality control" is a term that is used in many industries, including healthcare and medicine, to describe the systematic process of ensuring that products or services meet certain standards and regulations. In the context of healthcare, quality control often refers to the measures taken to ensure that the care provided to patients is safe, effective, and consistent. This can include processes such as:
1. Implementing standardized protocols and guidelines for care
2. Training and educating staff to follow these protocols
3. Regularly monitoring and evaluating the outcomes of care
4. Making improvements to processes and systems based on data and feedback
5. Ensuring that equipment and supplies are maintained and functioning properly
6. Implementing systems for reporting and addressing safety concerns or errors.
The goal of quality control in healthcare is to provide high-quality, patient-centered care that meets the needs and expectations of patients, while also protecting their safety and well-being.
Quality of health care is a term that refers to the degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledge. It encompasses various aspects such as:
1. Clinical effectiveness: The use of best available evidence to make decisions about prevention, diagnosis, treatment, and care. This includes considering the benefits and harms of different options and making sure that the most effective interventions are used.
2. Safety: Preventing harm to patients and minimizing risks associated with healthcare. This involves identifying potential hazards, implementing measures to reduce errors, and learning from adverse events to improve systems and processes.
3. Patient-centeredness: Providing care that is respectful of and responsive to individual patient preferences, needs, and values. This includes ensuring that patients are fully informed about their condition and treatment options, involving them in decision-making, and providing emotional support throughout the care process.
4. Timeliness: Ensuring that healthcare services are delivered promptly and efficiently, without unnecessary delays. This includes coordinating care across different providers and settings to ensure continuity and avoid gaps in service.
5. Efficiency: Using resources wisely and avoiding waste, while still providing high-quality care. This involves considering the costs and benefits of different interventions, as well as ensuring that healthcare services are equitably distributed.
6. Equitability: Ensuring that all individuals have access to quality healthcare services, regardless of their socioeconomic status, race, ethnicity, gender, age, or other factors. This includes addressing disparities in health outcomes and promoting fairness and justice in healthcare.
Overall, the quality of health care is a multidimensional concept that requires ongoing evaluation and improvement to ensure that patients receive the best possible care.
An artificial larynx, also known as a voice prosthesis or speech aid, is a device used to help individuals who have undergone a laryngectomy (surgical removal of the larynx) or have other conditions that prevent them from speaking normally. The device generates sound mechanically, which can then be shaped into speech by the user.
There are two main types of artificial larynx devices:
1. External: This type of device consists of a small electronic unit that produces sound when the user presses a button or activates it with a breath. The sound is then directed through a tube or hose into a face mask or a mouthpiece, where the user can shape it into speech.
2. Internal: An internal artificial larynx, also known as a voice prosthesis, is implanted in the body during surgery. It works by allowing air to flow from the trachea into the esophagus and then through the voice prosthesis, which creates sound that can be used for speech.
Both types of artificial larynx devices require practice and training to use effectively, but they can significantly improve communication and quality of life for individuals who have lost their natural voice due to laryngeal cancer or other conditions.
Quality Assurance in the context of healthcare refers to a systematic approach and set of activities designed to ensure that health care services and products consistently meet predetermined standards of quality and safety. It includes all the policies, procedures, and processes that are put in place to monitor, assess, and improve the quality of healthcare delivery.
The goal of quality assurance is to minimize variability in clinical practice, reduce medical errors, and ensure that patients receive evidence-based care that is safe, effective, timely, patient-centered, and equitable. Quality assurance activities may include:
1. Establishing standards of care based on best practices and clinical guidelines.
2. Developing and implementing policies and procedures to ensure compliance with these standards.
3. Providing education and training to healthcare professionals to improve their knowledge and skills.
4. Conducting audits, reviews, and evaluations of healthcare services and processes to identify areas for improvement.
5. Implementing corrective actions to address identified issues and prevent their recurrence.
6. Monitoring and measuring outcomes to evaluate the effectiveness of quality improvement initiatives.
Quality assurance is an ongoing process that requires continuous evaluation and improvement to ensure that healthcare delivery remains safe, effective, and patient-centered.
Speech recognition software, also known as voice recognition software, is a type of technology that converts spoken language into written text. It utilizes sophisticated algorithms and artificial intelligence to identify and transcribe spoken words, enabling users to interact with computers and digital devices using their voice rather than typing or touching the screen. This technology has various applications in healthcare, including medical transcription, patient communication, and hands-free documentation, which can help improve efficiency, accuracy, and accessibility for patients and healthcare professionals alike.
I'm sorry for any confusion, but "Linear Models" is actually a term from the field of statistics and machine learning, rather than medicine. A linear model is a type of statistical model that is used to analyze the relationship between two or more variables. In a linear model, the relationship between the dependent variable (the outcome or result) and the independent variable(s) (the factors being studied) is assumed to be linear, meaning that it can be described by a straight line on a graph.
The equation for a simple linear model with one independent variable (x) and one dependent variable (y) looks like this:
y = β0 + β1*x + ε
In this equation, β0 is the y-intercept or the value of y when x equals zero, β1 is the slope or the change in y for each unit increase in x, and ε is the error term or the difference between the actual values of y and the predicted values of y based on the linear model.
Linear models are widely used in medical research to study the relationship between various factors (such as exposure to a risk factor or treatment) and health outcomes (such as disease incidence or mortality). They can also be used to adjust for confounding variables, which are factors that may influence both the independent variable and the dependent variable, and thus affect the observed relationship between them.
Healthcare Quality Indicators (QIs) are measurable elements that can be used to assess the quality of healthcare services and outcomes. They are often based on evidence-based practices and guidelines, and are designed to help healthcare providers monitor and improve the quality of care they deliver to their patients. QIs may focus on various aspects of healthcare, such as patient safety, clinical effectiveness, patient-centeredness, timeliness, and efficiency. Examples of QIs include measures such as rates of hospital-acquired infections, adherence to recommended treatments for specific conditions, and patient satisfaction scores. By tracking these indicators over time, healthcare organizations can identify areas where they need to improve, make changes to their processes and practices, and ultimately provide better care to their patients.
Esophageal speech is not a type of "speech" in the traditional sense, but rather a method of producing sounds or words using the esophagus after a laryngectomy (surgical removal of the voice box). Here's a medical definition:
Esophageal Speech: A form of alaryngeal speech produced by swallowing air into the esophagus and releasing it through the upper esophageal sphincter, creating vibrations that are shaped into sounds and words. This method is used by individuals who have undergone a laryngectomy, where the vocal cords are removed, making traditional speech impossible. Mastering esophageal speech requires extensive practice and rehabilitation.

- This text-to-speech AI voice editor has got dozens of parameters for quality check. (internetvibes.net)
- Statistics show that nearly 90% of people impaired with PD develop voice and speech disorders. (uwo.ca)
- Speech production impairments in PD subjects typically result in hypophonia and consequently, poor speech signal-to-noise ratio (SNR) in noisy environments and inferior speech intelligibility and quality. (uwo.ca)
- Assessment, monitoring, and improvement of the perceived quality and intelligibility of Parkinsonian voice and speech are, therefore, paramount. (uwo.ca)
- The second study focused on the prediction of amplified Parkinsonian speech quality. (uwo.ca)
- To benchmark the amplifier performance, subjective ratings of the quality of speech samples from 11 PD patients and 10 control subjects using 7 different speech amplifiers in different background noise conditions were collected. (uwo.ca)
- It was shown that the speech amplifiers differentially affect Parkinsonian speech quality and that the composite objective metric resulted in a correlation of 0.85 with subjective speech quality ratings. (uwo.ca)
- In the third study, a new signal-to-noise feedback (SNF) device was designed and developed to help PD patients control their speech SNR, intelligibility, and quality. (uwo.ca)
- The proposed SNF device contained dual ear-level microphones for estimating the speech SNR, a throat accelerometer for reliable voice activity detection, and visual/auditory alarms when the produced speech was below a certain threshold. (uwo.ca)
- Performance evaluation of this device in noisy environments demonstrated significant improvements in speech SNR, perceived intelligibility, and predicted quality, especially in high background noise levels. (uwo.ca)
- Nearly 90% of people impaired with Parkinson's disease (PD) develop voice and speech disorders during the course of their disease. (uwo.ca)
- Therefore, there is a clinical need to assess the speech quality for people impaired with PD. (uwo.ca)
- Traditionally, voice and speech quality are evaluated by a panel of listeners (subjective assessment). (uwo.ca)
- While this may be the gold standard, objective estimation of speech quality through computational models is more robust and time and cost-efficient approach. (uwo.ca)
- This thesis focuses on the development and evaluation of such objective Parkinsonian speech and voice quality estimators. (uwo.ca)
- There is a need to machine learning algorithms to map the acoustic characteristics to the behavioral assessment of speech quality. (uwo.ca)
- In the second contribution of this study, another set of objective metrics are developed to assess the quality of Parkinsonian running speech. (uwo.ca)
- This research study also benchmarked the effect of speech amplifiers on Parkinsonian speech quality. (uwo.ca)
- In the third contribution of this study, a new device is developed and presented to help people impaired with PD to enhance and improve their speech quality and intelligibility. (uwo.ca)
- This research examines the concept of intergenerational choral singing as a behavioral intervention for speech and voice in Parkinson's Disease (PD). (ku.edu)
- At three dates, acoustic data regarding frequency, intensity, voice onset time, triangular vowel space area, diadochokinetic rate, maximum phonation duration, and pause number and mean duration were gathered during the completion of structured speech tasks. (ku.edu)
