Abstract
Objective
To examine the effects of respiratory muscle training on respiratory function, respiratory
muscle strength, and exercise tolerance in patients poststroke.
Data Sources
We searched MEDLINE, Cochrane Library, Embase, SciELO, Physiotherapy Evidence Database
(PEDro), and CINAHL (from the earliest date available to November 2015) for trials.
Study Selection
Randomized controlled trials (RCTs) that examined the effects of respiratory muscle
training versus nonrespiratory muscle training in patients poststroke. Two reviewers
selected studies independently.
Data Extraction
Extracted data from the published RCTs. Study quality was evaluated using the PEDro
Scale. Weighted mean differences (WMDs), standard mean differences (SMDs), and 95%
confidence intervals (CIs) were calculated.
Data Synthesis
Eight studies met the study criteria. Respiratory muscle training improved maximal
inspiratory pressure WMDs (7.5; 95% CI, 2.7–12.4), forced vital capacity SMDs (2.0;
95% CI, 0.6–3.4), forced expiratory volume at 1 second SMDs (1.2; 95% CI, 0.6–1.9),
and exercise tolerance SMDs (0.7; 95% CI, 0.2–1.2). No serious adverse events were
reported.
Conclusions
Respiratory muscle training should be considered an effective method of improving
respiratory function, inspiratory muscle strength, and exercise tolerance in patients
poststroke. Further research is needed to determine optimum dosages and duration of
effect.
