J07 The Effects Of Respiratory Muscle Training On Pulmonary And Swallowing Function In Huntington's Disease Patients

Objective: To determine the effectiveness of respiratory muscle training in persons with Parkinson’s disease. Data sources: PubMed/MEDLINE, EMBASE, Web of Science, Scopus and PEDro electronic databases were searched until 15 November 2019. Reference lists of included studies were hand-searched. Methods: Randomized controlled trials assessing the effects of respiratory muscle training programmes (both inspiratory and expiratory) in patients with Parkinson’s disease were included. Two reviewers independently identified eligible studies and extracted data. Method quality was appraised with the PEDro scale. Results: Five papers including three randomized controlled trials with a total of 111 patients were identified. Method appraisal showed a mean score of 5 in the PEDro scale. One study analysed inspiratory muscle training, one expiratory muscle training and two established a comparison between both of them. Statistically positive results were found in maximal inspiratory pressure ( P < 0.05 and d = 0.76), maximal expiratory pressure ( P < 0.01 and d = 1.40), perception of dyspnoea ( P < 0.01), swallowing function ( d = 0.55) and phonatory measures, without significant differences in spirometric indices. Conclusions: Respiratory muscle training may be an effective alternative for improving respiratory muscle strength, swallowing function and phonatory parameters in subjects with Parkinson’s disease. Nevertheless, the lack of primary studies about this type of training prevents obtaining robust evidence.

AbstractBackgroundDysphagia is prevalent with cerebrovascular accidents and contributes to the burden of disease and mortality. Strengthening of the dysfunctional swallow muscles through respiratory muscle training (RMT) has proven effective in improving swallow effectiveness and safety. However, approaches to strengthen only the expiratory muscle groups (EMST) dominate the clinical study literature, with variable outcomes. This study investigated the effect of a simultaneous inspiratory and expiratory muscle strengthening strategy to improve swallowing function in stroke patients.MethodsTwenty post-stroke patients were randomly assigned to either intervention group (IG) or control group (CG). The intervention group was treated with three 5-minute sessions of resistive respiratory muscle training every day for 28 days, while the control group received no RMT. Respiratory and swallow outcomes were assessed pre- and post-intervention and included Mann Assessment of Swallowing Ability (MASA), Fiberoptic Endoscopic Evaluation of Swallowing (FEES) with Penetration/Aspiration Scale (PAS), Functional Oral Intake Scale (FOIS), patient visual analogue scale (VAS), and peak expiratory flow (PEF).ResultsAfter 28 days, the intervention group demonstrated greater improvements (pVal < 0.05) in PEF (IG: 168.03% vs CG: 17.47%), VAS (IG: 103.85% vs CG: 27.54%), MASA (IG: 37.28% vs CG: 6.92%), PAS (IG: 69.84% vs CG: 12.12%), and FOIS (IG: 93.75% vs CG: 21.21%).ConclusionCombined resistive inspiratory and expiratory muscle training is a feasible and effective method to improve signs and symptoms of dysphagia in stroke patients.
