Abstract Background Stroke can lead to varying degrees of oropharyngeal dysphagia, respiratory muscle dysfunction and even increase medical complications such as aspiration, malnutrition and death. Recent studies suggest that inspiratory and expiratory respiratory muscle training (IEMT) can improve swallowing efficacy and may reduce aspiration events. The main purpose of this study is to examine whether an 8-week IEMT programme can improve respiratory muscle strength and swallow dysfunction severity in subacute stroke patients with dysphagia. Methods Retornus-2 is a two-arm, prospectively registered, randomized controlled study with blinded assessors and the participation of fifty individuals who have suffered a stroke. The intervention group undergoes IEMT training consisting of 5 sets of 10 repetitions, three times a day for 8 weeks. Training loads increase weekly. The control group undergoes a sham-IEMT protocol. The primary outcome examines the efficacy of the IEMT protocol to increase respiratory muscle strength and reduce dysphagia severity. The secondary outcome assesses the longitudinal impact of dysphagia on body composition and nutritional assessment over a 6-month follow-up. Discussion IEMT induces an improvement in respiratory muscle strength and might be associated with relevant benefits in dysphagia patterns, as well as a reduction in the number of aspiration events confirmed by videofluoroscopy or fiberoptic endoscopic evaluation of swallowing. The description of the impact of swallowing impairment on nutritional status will help develop new strategies to face this known side-effect. Trial registration Clinicaltrials.gov NCT03021252.

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.
