[PMID: 35260288 DOI: 10.1016/j.jvoice.2022.01.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 01/07/2022] [Accepted: 01/10/2022] [Indexed: 11/25/2022]
Abstract
OBJECTIVES Patients with chronic cough are some of the most challenging to treat. This preliminary study is the first to examine the effects of a single exercise muscle strength training program to reduce cough severity in patients who failed other treatments. METHODS A total of 19 females were included in this study, ranging from age 24 to 80. The maximum phonation time (MPT), laryngeal airway resistance (LAR), maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), Voice Handicap Index-10, (VHI-10) and the Cough Severity Index (CSI) values were obtained pre- and post-treatment. ANOVA two-factor without replication was used to compare values pre- and post-treatment. RESULTS MIP (Mean of 62.00 to a mean of 78.53) and MEP (Mean of 90.00 to a mean of 112.16) showed significant increase post-treatment. In addition, LAR (Mean of 73.30 to a mean of 60.67) and CSI (Mean of 19.37 to a mean of 15.00) significantly decreased post-treatment. General changes in pre- and post-treatment values were identified with MPT (Mean of 14.89 to a mean of 16.17) and VHI-10 (Mean of 8.00 to a mean of 6.76). A follow-up questionnaire indicated that the majority of patients felt their cough was better after 4 weeks. CONCLUSIONS Muscle strength training provides a tool to aid in the control of cough for patients who are refractory to medical and other behavioral treatments. Improvement in cough may be associated with a reduction in subglottic pressure and increased air flow resulting in lower laryngeal airway resistance.

[PMID: 36631345 DOI: 10.1016/j.jvoice.2022.11.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 11/22/2022] [Accepted: 11/23/2022] [Indexed: 01/11/2023]
Abstract
OBJECTIVES This study aimed to investigate the possible vocal impact confirmed by diagnostic tests, the degree of perception of possible vocal impairment by patients with Unilateral Diaphragmatic paralysis (UDP) and its correlation with ventilatory weakness. METHODS The researchers conducted an analytical, observational and case-control study with 70 individuals, including 35 UDP patients and 35 healthy patients in a control group, who underwent the following assessments: 1) Self-assessment of voice handicap (VHI-10); 2) Self-Assessment of Quality of Life (SF-36); 3) Self-Assessment of Dyspnea (MRC); 4) Objective vocal measures (Maximum Phonation Time (MPT) in /a/, /s/, /z/ and glottal-to-noise excitation ratio); 5) Functional respiratory pressures (Spirometry and maximum ventilatory pressures); 6) General degree of dysphonia - G on the GRBAS Scale. The sex, age and body mass index (BMI) of the individuals were the variables used to match the sample of this study. RESULTS When compared with controls, patients with UDP had a restrictive functional pattern and inspiratory weakness, with symptoms of dyspnea and worsening quality of life. When associated with a possible vocal impact, these patients had voice handicap and decreased MPT values for all phonemes, especially /a/. There was also a correlation between vocal performance and inspiratory weakness. However, it should be noted that, despite having vocal impairment, many patients did not report the perception of this fact, somehow neglecting such impairment. CONCLUSIONS In addition to the expected weakness of the ventilatory muscles, patients with UDP had clinically verified vocal impact, and those who had greater inspiratory weakness also had greater voice impairment. Finally, it is relevant that not all patients perceived such vocal impact, which showed a very reduced perception of this impairment in patients with UDP.

Using Ultrasound to Document the Effects of Expiratory Muscle Strength Training (EMST) on the Geniohyoid Muscle. Dysphagia 2021; 37:788-799. [PMID: 34132896 DOI: 10.1007/s00455-021-10328-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Accepted: 06/08/2021] [Indexed: 10/21/2022]
Abstract
Expiratory muscle strength training (EMST) is an exercise program designed to strengthen the muscles of expiration by increasing expiratory load during breathing exercises using either resistive or pressure threshold devices. Previous research has shown that EMST may increase submental suprahyoid muscle activity as measured with surface electromyography. The impact of EMST on submental muscles is of interest to those who treat dysphagia. The purpose of this study was to determine whether the cross-sectional area of the geniohyoid muscle changes as observed with ultrasound during a 5-week EMST program performed at 75% of maximum expiratory strength using the EMST150 device in healthy adults. Ten healthy adults participated in the 5-week program. Maximum expiratory pressure (MEP) and cross-sectional area of the geniohyoid muscle were measured weekly. Geniohyoid cross-sectional area was measured from ultrasound images recorded in the coronal plane. Repeated Measures ANOVA was used to determine whether there were significant changes among the dependent variables over the study period. Both MEP and geniohyoid area increased significantly in response to a 5-week program of EMST. EMST in healthy adults is effective at strengthening the geniohyoid muscle as reflected by significantly increased cross-sectional area measured with B-mode ultrasound. This is the first study to document weekly change in muscle morphology as a result of EMST. Increasing geniohyoid muscle mass and consequent strength through a program of EMST may be beneficial for persons with pharyngeal stage dysphagia resulting from reduced hyolaryngeal elevation, reduced laryngeal closure, or reduced UES opening.

Abstract
Purpose Expiratory muscle strength training (EMST) is increasingly utilized in dysphagia rehabilitation; however, little is known about the effects of this approach on swallowing function or physiology. We conducted a systematic review to appraise and synthesize evidence regarding the effects of EMST on videofluoroscopic measures of swallowing in individuals with medical diagnoses, in which dysphagia is a concern. Method A literature search was conducted according to Cochrane guidelines. Of 292 nonduplicate articles, 11 were judged to be relevant for review. These underwent detailed review for study quality, risk of bias evaluation, and synthesis of swallowing outcomes. Results The selected articles described EMST in a variety of patient populations using either the EMST150 or the Phillips Threshold positive expiratory pressure device. The typical protocol involved five sets of five breaths through the device (25 breaths/day), 5 days per week for 4 weeks. Exercise loads were set between 50% and 75% depending on the population, and treatment was typically supervised by a clinician weekly. The Penetration-Aspiration Scale was the most commonly reported videofluoroscopic outcome measure. Conclusions differed as to whether or not swallowing improved following a course of EMST. Differences in videofluoroscopy protocols, methods of summarizing participant performance, and statistical approaches across studies meant that meta-analysis of swallowing outcomes could not be completed. Conclusion This review failed to find clear evidence regarding the effects of EMST on videofluoroscopic measures of swallowing. Heterogeneity in the etiologies and baseline severity of dysphagia across studies and in the methods used to measure swallowing outcomes was a particular barrier to data synthesis.

Abstract
INTRODUCTION In individuals with Parkinson's disease (PD), respiratory muscle weakness and rigidity, bradykinesia of abdominal muscles and stiffness of the chest wall, affect the respiratory component of voice intensity due to reduced pulmonary capacity and airflow needed to vibrate the vocal folds. It may be possible to improve voice production by strengthening respiratory muscles. The purpose of this study was to evaluate the effects of inspiratory and expiratory muscle training on voice production outcomes in individuals with PD. METHOD Thirty-one participants with PD were randomly allocated to three study groups (control group n = 10, inspiratory training group, n = 11, and expiratory training group, n = 11). The inspiratory and expiratory group performed a home-based inspiratory and expiratory muscle training program, respectively (five sets of five repetitions). Both groups trained six times a week for 2 months using a progressively increased resistance. The control group performed expiratory muscle training using the same protocol and a fixed resistance. Phonatory measures, maximum inspiratory/expiratory pressure, and spirometric indexes were assessed before and at 2 months after training. RESULTS Differences in peak subglottic pressure were moderate (d = 0.59) between expiratory and inspiratory groups, large between inspiratory and control groups (d = 1.32), and large between expiratory and control groups (d = 1.96). Differences in maximum phonation time were large (d = 1.26) between inspiratory and control groups, moderate (negative) between expiratory and inspiratory groups (d = -0.60), and moderate between expiratory and control groups (d = 0.72). Differences in peak sound pressure level were large (d = 1.27) between inspiratory and control groups, trivial between expiratory and inspiratory groups (d = -0.18), and large between expiratory and control groups (d = 1.10). CONCLUSIONS Inspiratory muscle training is effective in improving maximum phonation time, and expiratory muscle training is more effective for improving peak subglottic pressure, and peak sound pressure level in individuals with PD.

Abstract
Introduction: Wind instrumentalists require a sophisticated functioning of their respiratory system. Aim: The purpose of this research is to examine the function of the respiratory system of wind instrumentalists. Material and methods: Thirty-two adult professional musicians from two philharmonic bands (Piraeus and Zografou Municipality) participated in the survey. Each participant, after completing a questionnaire given, went through two spirometric tests, one before and one after the rehearsal. The rehearsal lasted one hour and a half and included low-mid and high frequency notes. Respiratory volumes measured and analyzed were, vital capacity (VC), maximum expiratory volume of air in 1st second (FEV1), forced vital capacity (FVC), forced expiratory flow (FEF), and Tiffenau index (FEV1/FV%). Results: The results showed that: 1) Participants did not show any noticeable change in their respiratory volumes before and after rehearsal. 2) Wind instrument players do not have a VC greater than their predicted age, height, weight and gender. 3) There is no statistically significant difference between the first and second assessment of respiratory indicators for smokers and non-smokers. 4) Regarding the type of instrument: a) Those who played wooden instruments improved the FEV1/FVC% indicator to a remarkable percentage between the first and second spirometry and b) individuals playing wooden instruments had a lower FVC, FEV1 and VC score than those playing bronze. Conclusion: There is no significant strain sign in respiratory system even in smokers after exercising in wind instrument. There is an improvement in Tiffenau index in those who played wooden instruments between the two rehearsals. Undoubtedly, new research is needed to combine a respiratory disease scenario with a respiratory treatment program that involves practicing a wind instrument.

Abstract
OBJECTIVE To conduct an interdisciplinary literature review on the function of the pelvic floor musculature during respiration and its role in phonation, particularly singing. STUDY DESIGN This is a literature review. METHODS A literature review was conducted using three electronic databases: PubMed, Scopus, and Google Scholar. An index search was also performed for the NATS Journal/Journal of Singing utilizing the keywords from the original search, as these articles did not appear in the original search. Peer-reviewed articles from 1985 to 2017 were gathered on the respiratory musculature and/or support mechanisms for phonation (anatomy and physiology). Articles that pertained to the muscular function of the respiratory system in breathing and/or phonation were utilized in the review. Eighty-five articles were included in this review. RESULTS Breathing and support strategies were variable and nonspecific in much of the singing voice literature. The voice science literature was a rich source of articles written about breathing and support for singing. Multiple studies looked at musculature utilized in respiration and breath support and subglottal pressure generation for muscular support. However, little or no mention was made specifically of the pelvic floor. The physical medicine literature includes the pelvic floor musculature as having an important role in respiration, as a key player in the generation of intra-abdominal pressure, and as a primary expiratory muscle. CONCLUSIONS The information gleaned from this literature review suggests that a cross-pollination between areas of science is needed, because quite obviously, the pelvic floor is a topic in physical medicine, but it is not (so much) in the voice literature. Reaching a consensus on how we describe the function of the respiratory musculature and specifically including the role of the pelvic floor in respiration and phonation deserves future attention. Further research looking specifically at the role of the pelvic floor in phonation is also warranted.

Abstract
PURPOSE The purpose of this study was to examine the impact of expiratory muscle strength training on speech breathing and functional speech outcomes in individuals with Parkinson's disease (PD). METHOD Twelve individuals with PD were seen once a week for 8 weeks: 4 pretraining (baseline) sessions followed by a 4-week training period. Posttraining data were collected at the end of the 4th week of training. Maximum expiratory pressure, an indicator of expiratory muscle strength, and lung volume at speech initiation were the primary outcome measures. Secondary outcomes included lung volume at speech termination, lung volume excursion, utterance length, and vocal intensity. Data were collected during a spontaneous speech sample. Individual effect sizes > 1 were considered significant. RESULTS Maximum expiratory pressure increased in a majority of participants after training. Training resulted in 2 main respiratory patterns: increasing or decreasing lung volume initiation. Lung volume termination and excursion, utterance length, and vocal loudness were not consistently altered by training. CONCLUSIONS Preliminary evidence suggests that the direct physiologic intervention of the respiratory system via expiratory muscle strength training improves speech breathing in individuals with PD, with participants using more typical lung volumes for speech following treatment.

Abstract
[Purpose] The aim of this investigation was to determine the effects of 4 weeks of fast expiration exercises performed without pressure on respiratory muscle strength. [Subjects and Methods] Respiratory muscle strength of the training group that performed fast expiration exercises (n=12) was compared with that of a control group that performed no exercises (n=12). The fast expiration exercises were performed using a peak expiratory flow meter device and consisted of 20 fast expiration exercises performed 3 times per week for 4 weeks. Maximal expiratory and inspiratory pressures were evaluated as respiratory muscle strength using a spirometer pre- and post- intervention. [Results] There were significant increases in maximal expiratory pressure from 76.9 ± 29.1 to 96.1 ± 37.5 cmH2O and maximal inspiratory pressure from 80.8 ± 36.6 to 95.3 ± 37.6 cmH2O in the training group, but there was no significant difference in respiratory muscle strength between pre- and post-intervention in the control group. [Conclusion] Fast expiration exercises may be beneficial for increasing respiratory muscle strength. The findings of this study should be considered when prescribing a variation of the expiratory muscle strength training, as part of a pulmonary rehabilitation program.

Abstract
PURPOSE The role of exercise in the management of people with amyotrophic lateral sclerosis (PALS) is controversial and currently unclear. The purpose of this review article is to review literature examining the impact of limb, respiratory, and oral motor exercise on function, disease progression, and survival in PALS and the transgenic ALS animal model. METHOD A literature review was conducted to examine relevant studies published in peer-reviewed journals between 1960 and 2014. All studies were appraised for quality of research and were assigned a level of evidence, and treatment outcomes were classified as either positive, negative, or neutral. RESULTS A total of 18 exercise-based intervention studies on limb (13), respiratory (3), or speech (2) function were identified. Of the human clinical trials, 6 were experimental and 4 were exploratory. No experimental studies were identified examining the impact of targeted exercise on speech or swallowing function. Mild to moderate intensity limb or respiratory exercise, applied early in the disease, was noted to have a beneficial impact on motor function and survival. CONCLUSION Insufficient data exist to support or refute the role of exercise in the management of bulbar dysfunction in PALS. This represents a critical area of future investigation.

Abstract
This review presents the available evidence for the effects of expiratory muscle strength training (EMST) with the use of a pressure threshold device. The investigators used computerized database searches for studies reporting the outcomes of pressure threshold EMST published after 1994. A total of 24 selected articles presented outcomes related but not limited to respiratory function, such as speech, swallow, voice, and cough function in persons with neurologic conditions such as Parkinson disease, multiple sclerosis, and Lance-Adams syndrome; in persons with respiratory diseases, such as chronic obstructive pulmonary disease; and in healthy young adults and sedentary and active elderly. Several studies demonstrated promising outcomes of EMST as a non-task-specific training for airway protection in persons with dysphagia secondary to neuromuscular impairments; however, further research is needed to confirm and generalize the reported findings.

Abstract
OBJECTIVE To examine the effects of 4-month of respiratory muscle training on pulmonary and swallowing function, exercise capacity and dyspnoea in manifest patients with Huntington's disease. DESIGN A pilot randomised controlled trial. SETTING Home based training program. PARTICIPANTS Eighteen manifest Huntington's disease patients with a positive genetic test and clinically verified disease expression, were randomly assigned to control group (n=9) and training group (n=9). INTERVENTION Both groups received home-based inspiratory (5 sets of 5 repetitions) and expiratory (5 sets of 5 repetitions) muscle training 6 times a week for 4 months. The control group used a fixed resistance of 9 centimeters of water, and the training group used a progressively increased resistance from 30% to 75% of each patient's maximum respiratory pressure. MAIN MEASURES Spirometric indices, maximum inspiratory pressure, maximum expiratory pressure, six minutes walk test, dyspnoea, water-swallowing test and swallow quality of life questionnaire were assessed before, at 2 and 4 months after training. RESULTS The magnitude of increases in maximum inspiratory (d=2.9) and expiratory pressures (d=1.5), forced vital capacity (d=0.8), forced expiratory volume in 1 second (d=0.9) and peak expiratory flow (d=0.8) was substantially greater for the training group in comparison to the control group. Changes in swallowing function, dyspnoea and exercise capacity were small (d ≤ 0.5) for both groups without substantial differences between groups. CONCLUSIONS A home-based respiratory muscle training program appeared to be beneficial to improve pulmonary function in manifest Huntington's disease patients but provided small effects on swallowing function, dyspnoea and exercise capacity.

Abstract
INTRODUCTION Huntington's disease (HD) patients have difficulty in swallowing, leading to aspiration pneumonia, which is a major cause of death. It seems possible that submental muscles that are crucial for preventing an escape of a bolus into the airway, are affected by HD, but no previous studies have investigated this. OBJECTIVE To assess surface electromyograph (sEMG) activity of submental muscles during swallowing and expiratory muscle training (EMT) tasks in HD patients in comparison to healthy volunteers. METHODS sEMG activities of submental muscles during saliva, water swallowing, EMT tasks performed at 25% and 75% of maximum expiratory pressure were recorded and normalised by the sEMG activity during an effortful swallow in 17 early to mid stage HD patients and 17 healthy volunteers. RESULTS sEMG activity was greater (p<0.05) during EMT tasks than saliva and water swallowing, but was not significantly different between groups for saliva, water swallowing and EMT at 25%. HD patients had lower sEMG activity for EMT at 75% (p<0.05). CONCLUSION Decreases in submental muscle activity were not evident in HD patients except during EMT at 75%. This suggests that relative submental muscle weakness is observed only during a high intensity task in early to mid stage HD patients.

Abstract
BACKGROUND Studies of the impact of respiratory muscle training (RMT) on central neurodegenerative pathologies have been aimed at improving pulmonary function. However, there is no certainty about the effectiveness of RMT in patients affected by these groups of disorders. The purpose of this review was to assess the evidence regarding the efficacy of inspiratory muscle training (IMT) and expiratory muscle training (EMT) on respiratory function in patients with neurodegenerative disorders of the CNS. METHODS A comprehensive search from 1990 to September 2012 on MEDLINE, Physiotherapy Evidence Database (PEDro), PubMed, Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases was made. Studies reporting on IMT and EMT in patients with neurodegenerative diseases were included. The selected studies were abstracted using a standardized data collection instrument and were assessed by a quality checklist created and adapted from CONSORT (Consolidated Standards for Reporting Trials) and TREND (Transparent Reporting of Evaluation with Nonrandomized Designs). RESULTS Twenty-four studies were identified by the search strategy. Only 19 studies met the criteria for full review. Ten studies met all the inclusion criteria and were included in the final analysis. Of the 16 parameters present in the quality assessment checklist, only six were achieved for the studies analyzed. CONCLUSIONS There is some evidence that RMT improves a number of respiratory function parameters in patients with Parkinson disease and multiple sclerosis; however, the number of studies and their quality are not sufficient to conclude whether IMT or EMT is effective in improving respiratory function in patients with neurodegenerative disorders of the CNS.

Abstract
[Purpose] The purpose of this study was to investigate the effect of expiratory
resistance load on the tongue area encompassing the suprahyoid and genioglossus muscles.
[Subjects] The subjects were 30 healthy individuals (15 males, 15 females, mean age:
28.9 years). [Methods] Magnetic resonance imaging was used to investigate morphological
changes in response to resistive expiratory pressure loading in the area encompassing the
suprahyoid and genioglossus muscles. Images were taken when water pressure was sustained
at 0%, 10%, 30%, and 50% of maximum resistive expiratory pressure. We then measured tongue
area using image analysis software, and the morphological changes were analyzed using
repeated measures analysis of variance followed by post hoc comparisons. [Results] A
significant change in the tongue area was detected in both sexes upon loading. Multiple
comparison analysis revealed further significant differences in tongue area as well as
changes in tongue area in response to the different expiratory pressures. [Conclusion] The
findings demonstrate that higher expiratory pressure facilitates greater reduction in
tongue area.

Abstract
BACKGROUND Voice disorders that result in reduced loudness may cause difficulty in communicating, socializing and participating in occupational activities. Amplification is often recommended in order to facilitate functional communication, reduce vocal load and avoid developing maladaptive compensatory behaviours. The most common microphone used with amplification systems is the electret microphone. One alternate form of microphone is the fiber optic microphone. AIMS To examine the benefits of the fiber optic (1190S) versus the electret (M04) microphone as measured by objective and subjective parameters in the amplification of a patient's voice with reduced loudness caused by neurological and/or respiratory-based problems. METHODS & PROCEDURES Eighteen patients with vocal fold paralysis, Parkinson's disease and/or chronic obstructive pulmonary disease (COPD) participated in the study. The study contained a measurement of intensity, amplitude perturbation and signal-to-noise ratio during a sustained vowel production and a measurement of intensity during conversation with the use of the two microphones simultaneously. It also included the completion of a questionnaire indicating the patient's satisfaction with each microphone. OUTCOMES & RESULTS The fiber optic (1190S) microphone had better objective acoustic performance (i.e. lower amplitude perturbation, higher signal-to-noise ratio and higher intensity) than the electret (M04) microphone. It also had better patient subjective satisfaction (i.e. less conspicuousness, more voice clarity, less acoustic feedback, more loudness and more utilization) than the electret microphone. CONCLUSIONS & IMPLICATIONS Patients with neurological and/or respiratory-based voice problems may more confidently and frequently use the fiber optic microphone to communicate, socialize and participate in occupational activities more easily. Speech-language pathologists may more confidently use or recommend the fiber optic microphone with amplification systems.

Abstract
PURPOSE To determine the effects of expiratory muscle strength training (EMST) frequency on maximum expiratory pressure (MEP). METHOD We assigned 12 healthy participants to 2 groups of training frequency (3 days per week and 5 days per week). They completed a 4-week training program on an EMST trainer (Aspire Products, LLC). MEP was the primary outcome measure used to determine the effect of training frequency. RESULTS Participants who trained 3 days per week produced equivalent amounts of improvement in MEP compared with participants who trained 5 days per week. An overall improvement in MEP over the 4-week training period indicated a 33% increase when the data was collapsed across the 2 training groups. CONCLUSION The effects occurring with respiratory muscle strength training in healthy young adults are likely to be different from those occurring in patient populations. Therefore, the results of the present study suggest exploring the variable of training frequency in patient populations. Such knowledge will be informative for designing clinical protocols that are effective and may result in improved treatment compliance for those suffering from expiratory muscle weakness.

Abstract
Expiratory muscle strength training (EMST) is a rehabilitative program that has been tested for outcomes related to respiratory muscle strength, cough, swallow, and voice function in healthy young adult, elderly individuals, and in patients with progressive neurodegenerative disease. Because EMST has been used in patient care, the associated cardiovascular responses during EMST are of importance. This study investigated the changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and oxygen saturation (SpO(2)) during one session of EMST in healthy, young adults as a preliminary study of device safety. Thirty-one participants completed a single session of 25 trials with the EMST device. Valsalva maneuvers were performed at the beginning and at the end of the EMST trials for task comparison. The SBP, DBP, HR, and SpO(2) were recorded at the baseline and after completing the following tasks: a Valsalva maneuver, 12 trials using the EMST device, 13 trials using the EMST device, and 5 min of rest following the EMST session. A mixed linear model tested for changes across the six time points. The results indicated no significant change of SBP, DBP, HR, or SpO(2) during or following the EMST trials or after performing the Valsalva maneuver. The results suggest that EMST does not elicit significant fluctuations of blood pressure, HR, and SpO(2) in healthy young adults even when considering the effects of covariates on the outcomes measures.

Abstract
OBJECTIVE Dysphagia is the main cause of aspiration pneumonia and death in Parkinson disease (PD) with no established restorative behavioral treatment to date. Reduced swallow safety may be related to decreased elevation and excursion of the hyolaryngeal complex. Increased submental muscle force generation has been associated with expiratory muscle strength training (EMST) and subsequent increases in hyolaryngeal complex movement provide a strong rationale for its use as a dysphagia treatment. The current study's objective was to test the treatment outcome of a 4-week device-driven EMST program on swallow safety and define the physiologic mechanisms through measures of swallow timing and hyoid displacement. METHODS This was a randomized, blinded, sham-controlled EMST trial performed at an academic center. Sixty participants with PD completed EMST, 4 weeks, 5 days per week, for 20 minutes per day, using a calibrated or sham, handheld device. Measures of swallow function including judgments of swallow safety (penetration-aspiration [PA] scale scores), swallow timing, and hyoid movement were made from videofluoroscopic images. RESULTS No pretreatment group differences existed. The active treatment (EMST) group demonstrated improved swallow safety compared to the sham group as evidenced by improved PA scores. The EMST group demonstrated improvement of hyolaryngeal function during swallowing, findings not evident for the sham group. CONCLUSIONS EMST may be a restorative treatment for dysphagia in those with PD. The mechanism may be explained by improved hyolaryngeal complex movement. CLASSIFICATION OF EVIDENCE This intervention study provides Class I evidence that swallow safety as defined by PA score improved post EMST.

Abstract
BACKGROUND Cystic fibrosis is a genetically inherited, life-threatening condition that affects major organs. The management of cystic fibrosis involves a multi-faceted daily treatment regimen that includes airway clearance physiotherapy, taking pancreatic enzymes and other medications. Previous studies identified that compliance with this intensive treatment especially among adolescents with cystic fibrosis is poor. Because of both the nature and consequences of the illness and the relentless demands of treatments, many individuals with cystic fibrosis are likely to have a poor quality of life. Anecdotal evidence suggests that singing may provide rigorous exercises for the whole respiratory system as well as a means for emotional expression, which may enhance quality of life. OBJECTIVES To evaluate the effects of a singing intervention in addition to usual therapy on the quality of life, morbidity, respiratory muscle strength and pulmonary function of children and adults with cystic fibrosis. SEARCH STRATEGY We searched the Group's Cystic Fibrosis Trials Register, the Cochrane Central Register of Controlled Trials, major allied complementary data bases, and clinical trial registers. Hand searching for relevant conference proceedings and journals was also carried out.Date of search of Trials Register: 02 September 2009.Date of additional searches: 17 September 2009. SELECTION CRITERIA Randomised controlled trials in which singing (as an adjunctive intervention) is compared with either a sham intervention or no singing in people with cystic fibrosis. DATA COLLECTION AND ANALYSIS No trials were found that met the selection criteria. MAIN RESULTS No meta-analysis could be performed. AUTHORS' CONCLUSIONS As no studies that met the criteria were found, this review is unable to support or refute the benefits of singing as a therapy for people with cystic fibrosis. Future randomised controlled trials are required to evaluate singing therapy for people with cystic fibrosis.

Abstract
BACKGROUND Bronchiectasis is a common respiratory disease, especially in developing countries. Its cause varies from chronic infection to rare immune deficiencies. Bronchiectasis can be present with other respiratory diseases, such as chronic obstructive pulmonary disease (COPD). People with bronchiectasis may suffer from chronic cough, fatigue, shortness of breath, chest pain and coughing up blood. Their lung function may decline with time. These can also have a negative impact on their quality of life. Thus, a holistic management is needed to provide treatment and support. Therapies which include breathing manoeuvres, such as singing, may have health benefits for respiratory function and psychological well being. OBJECTIVES To evaluate the effects of a singing intervention as a therapy on the quality of life, morbidity, respiratory muscle strength and pulmonary function of children and adults with bronchiectasis. SEARCH STRATEGY We searched the Cochrane Airways Group (CAG) trials register, the Cochrane Central Register of Controlled Trials, major allied complementary databases, and clinical trials registers. Professional organisations and individuals were also contacted. CAG performed searches in February, and additional searches were carried out in June 2009. SELECTION CRITERIA Randomised controlled trials in which singing (as an intervention) is compared with either a sham intervention or no singing in patients with bronchiectasis. DATA COLLECTION AND ANALYSIS Two authors independently reviewed the titles, abstracts and citations to assess potential relevance for full review. No eligible trials were identified and thus no data were available for analysis. MAIN RESULTS No meta-analysis could be performed. AUTHORS' CONCLUSIONS In the absence of data, we cannot draw any conclusion to support or refute the adoption of singing as an intervention for people with bronchiectasis. Given the simplicity of the potentially beneficial intervention, future randomised controlled trials are required to evaluate singing therapy for people with bronchiectasis.

Abstract
BACKGROUND Cough provides high expiratory airflows to aerosolize and remove material that cannot be adequately removed by ciliary action. Cough is particularly important for clearing foreign particles from the airway in those with dysphagia who may be at risk for penetration/aspiration (P/A). Expiratory muscle strength training (EMST) was tested to improve cough and swallow function. METHODS Ten male participants, diagnosed with Parkinson disease (PD), with videofluorographic evidence of penetration or with evidence for aspiration of material during swallow of a thin 30-mL bolus, completed 4 weeks of an EMST program to test the hypothesis that EMST would improve cough and/or swallow function. Measured parameters from an airflow waveform produced during voluntary cough, pre-EMST and post-EMST, included inspiration phase duration, compression phase duration (CPD), expiratory phase peak flow (EPPF), expiratory phase rise time (EPRT), and cough volume acceleration (VA) [ie, the EPPF/EPRT ratio]. The swallow outcome measure was the degree of P/A during the swallow task. RESULTS There was a significant decrease in the duration of the CPD and EPRT; the decrease in EPRT resulted in a significant increase in cough VA. Significant decreases in the P/A scores were found posttraining. CONCLUSIONS The results demonstrate that EMST is a viable treatment modality for a population of participants with PD at risk of aspiration.

Abstract
PURPOSE The purpose of this article is to help speech-language pathologists (SLPs) apply the principles of evidence-based practice (EBP) to nonspeech oral motor treatments (NSOMTs) in order to make valid, evidence-based decisions about NSOMTs and thus determine if they are viable treatment approaches for the management of communication disorders. METHOD A detailed description of EBP is provided, including levels of evidence for rating the quality of evidence. NSOMTs are described and a survey of the literature on NSOMTs is provided along with a determination of the level of evidence of each study reported. A systematic literature search was conducted using the electronic databases of MEDLINE and CINAHL (Cumulative Index to Nursing and Allied Health Literature) within an unrestricted time period. In addition, reference lists from identified articles were also reviewed. Ethical and fiscal issues related to EBP and NSOMTs, as well as clinical implications of EBP for the use of NSOMTs, are discussed. RESULTS A total of 45 articles/reports were published between 1981 and 2006 in peer-reviewed and non-peer-reviewed journals. Most of the sources (25) relied on weak anecdotal evidence and opinions. Moreover, studies that employed stronger designs reported negative results for NSOMTs (i.e., evidence against the use of NSOMTs for modifying speech). CONCLUSION Despite their use for many years and their popularity among some SLPs for the treatment of a wide variety of speech problems in children and adults, NSOMTs are controversial because sufficient evidence does not exist to support their effectiveness in improving speech. Moreover, limited evidence exists for the use of NSOMTs to facilitate nonspeech activities. Therefore, the available evidence does not support the continued use of NSOMTs as a standard treatment and they should be excluded from use as a mainstream treatment until there are further data. SLPs should consider the principles of EBP in making decisions about NSOMTs.

Abstract
PURPOSE To describe the frequency and types of injuries and illnesses sustained by student members of a high school marching band. METHODS A descriptive, correlation retrospective study of 2 years of marching band camp health clinic logs. RESULTS There were 378 nursing intervention clinic visits for 178 students in 2005 and 596 visits for 224 students in 2006. The visit frequency peaked on Day 3 of full band camp practice. The most common complaint was lower musculoskeletal injury, followed by skin rashes. Significant correlations were found between day of camp, blisters, menstruation, insect bites, asthma, heat distress, and musculoskeletal injuries. CLINICAL IMPLICATIONS Safeguards need to be investigated to protect the musculoskeletal integrity of these high school students. In response to the unique needs of marching band students, the National Athletic Trainers' Association has established guidelines to ensure the safety of these students on the practice field and in public performances.

Abstract
PURPOSE This study investigated the concurrent biomechanical and electromyographic properties of 2 swallow-specific tasks (effortful swallow and Mendelsohn maneuver) and 1 swallow-nonspecific (expiratory muscle strength training [EMST]) swallow therapy task in order to examine the differential effects of each on hyoid motion and associated submental activation in healthy adults, with the overall goal of characterizing task-specific and overload properties of each task. METHOD Twenty-five healthy male and female adults (M = 25 years of age) participated in this prospective, experimental study with 1 participant group. Each participant completed all study tasks (including normal swallow, Mendelsohn maneuver swallow, effortful swallow, and EMST task) in random order during concurrent videofluoroscopy and surface electromyography recording. RESULTS Results revealed significant differences in the trajectory of hyoid motion as measured by overall displacement and angle of elevation of the hyoid bone. As well, timing of hyoid movement and amplitude differences existed between tasks with regard to the activation of the submental musculature. CONCLUSIONS Study results demonstrated differential effects of the 3 experimental tasks on the principles of task specificity and overload. These principles are important in the development of effective rehabilitative programs. Subsequent direction for future research is suggested.

Abstract
Professional voice users comprise 25% to 35% of the U.S. working population. Their voice problems may interfere with job performance and impact costs for both employers and employees. The purpose of this study was to examine treatment outcomes of two specific rehabilitation programs for a group of professional voice users. Eighteen professional voice users participated in this study; half had complaints of throat pain or vocal fatigue (Dysphonia Group), and half were found to have benign vocal fold lesions (Lesion Group). One group received 5 weeks of expiratory muscle strength training followed by six sessions of traditional voice therapy. Treatment order was reversed for the second group. The study was designed as a repeated measures study with independent variables of treatment order, laryngeal diagnosis (lesion vs non-lesion), gender, and time. Dependent variables included maximum expiratory pressure (MEP), Voice Handicap Index (VHI) score, Vocal Rating Scale (VRS) score, Voice Effort Scale score, phonetogram measures, subglottal pressures, and acoustic and perceptual measures. Results showed significant improvements in MEP, VHI scores, and VRS scores, subglottal pressure for loud intensity, phonetogram area, and dynamic range. No significant difference was found between laryngeal diagnosis groups. A significant difference was not observed for treatment order. It was concluded that the combined treatment was responsible for the improvements observed. The results indicate that a combined modality treatment may be successful in the remediation of vocal problems for professional voice users.

Abstract
Purpose. This study investigated the effect of expiratory muscle strength training (EMST) on voice production, dysarthria, and voice-related quality-of-life issues in persons with multiple sclerosis (PwMS). It was hypothesized that PwMS would have improved voice production and reduced voice-related quality-of-life issues following EMST. Participants and Methods. Seventeen participants with MS and 14 healthy (H) controls completed 8 weeks of EMST, followed by 4 weeks of no training. Analyzed outcomes as a function of EMST were maximal expiratory pressure (MEP), sustained vowel prolongation (SVP), words per minute (WPM) measured from connected speech, and quality-of-life indices related to the presence of the dysarthria and dysphonia. Results. PwMS had lower MEPs, shorter SVP, and less WPM than the controls prior to training. Following EMST, both groups had significant improvement in MEPs that stayed above baseline after training halted. EMST did not improve voice production or voice-related quality of life for PwMS. Conclusion. Respiratory muscle weakness is present in PwMS having mild- to moderate-level disability. EMST improved expiratory muscle strength but did not statistically change objective and subjective components of voice/speech production in PwMS.

Abstract
The use of expiratory muscle strength trainers improves parameters related to pulmonary function, speech, and cough in both healthy and patient populations. Recently, it has been speculated that expiratory strength training may alter the force generation of muscles used during the swallow process. Specifically, the use of the trainer may result in increased activation of the submental muscle complex. Support for this hypothesis was tested by examining the timing and amplitude of submental muscle activity obtained using surface EMG. These muscles are known to be important for normal swallow function. Twenty participants (10 males, 10 females; mean age = 29 years) were recruited to participate in a one-session study. Participants were asked to perform two swallows (saliva swallow and water swallow) and develop an expiratory pressure set at 25% and 75% of their maximum expiratory pressure (MEP) using an expiratory muscle strength trainer. These tasks allowed comparison of muscle activity during both the swallow and expiratory tasks completed with the trainer. Results indicated that the patterns of activation in the submental muscle group while training on the expiratory device had longer duration of activation with higher amplitude of EMG activity when compared with the swallowing condition. These findings indicate that expiratory muscle strength training (EMST) increases motor unit recruitment of the submental muscle complex. Discussion centers on the potential benefit of EMST as a treatment modality for dysphagia characterized by decreased amplitude of hyoid movement during swallowing.

Abstract
PURPOSE The purpose of this study was to determine strength gains following expiratory muscle strength training (EMST) and to determine detraining effects when the training stimulus is removed. METHOD Thirty-two healthy participants were enrolled in an EMST program. Sixteen participants trained for 4 weeks (Group 1) and 16 participants trained for 8 weeks (Group 2). All 32 participants were detrained for 8 weeks. Maximum expiratory pressure (MEP) was used to document change in expiratory muscle strength throughout the study. RESULTS Group 1 had a 41% increase and Group 2 had a 51% increase in MEP following the training. Mean MEP, for both groups, was significantly greater than baseline at the end of the training period (p = .0001), at the 4th week of detraining (p = .0001), and at the 8th week of detraining (p = .0001). The results also indicated that there was no significant difference in mean MEP between the groups at baseline, end of training, or throughout the detraining period (p = .960). DISCUSSION The results suggest that expiratory muscle strength gains following a 4- and 8-week EMST program do not differ significantly. Additionally, detraining rates do not appear to be dependent on length of training time.

Abstract
Voice problems are a common occupational hazard of teaching school, yet few studies exist that have objectively evaluated treatment approaches aimed at rehabilitating these occupation-related voice disorders. This randomized clinical trial used patient-based treatment outcome measures to evaluate the effectiveness of three treatment programs. Sixty-four teachers with voice disorders were randomly assigned to 1 of 3 treatment groups: voice amplification using the ChatterVox portable amplifier (VA; n = 25), resonance therapy (RT; n = 19), and respiratory muscle training (RMT; n = 20). Before and after a 6-week treatment phase, all teachers completed (a) the Voice Handicap Index (VHI; B. H. Jacobson et al., 1997), an instrument designed to appraise the self-perceived psychosocial consequences of voice disorders, and (b) a voice severity self-rating scale. Both intention-to-treat and as-treated analyses revealed that only the VA and RT groups reported significant reductions in mean VHI scores and in voice severity self-ratings following treatment. Furthermore, results from a posttreatment questionnaire regarding the perceived benefits of treatment showed that compared to RT and RMT, teachers in the VA group reported significantly more overall voice improvement, greater vocal clarity, and greater ease of speaking and singing voice following treatment. These findings replicate previous results from an earlier clinical trial confirming the efficacy of VA and provide new evidence to support RT as an effective treatment alternative for voice problems in teachers. The results are discussed in the context of uneven levels of self-reported compliance and disparate dropout rates among the treatment groups.
