Efficacy of Interventions to Improve Respiratory Function After Stroke.

Area of Science:

• Neurology
• Pulmonology
• Rehabilitation Medicine

Background:

• Stroke frequently impairs respiratory function and activity.
• Improving respiratory function is crucial for recovery and quality of life after stroke.

Purpose of the Study:

• To systematically review interventions aimed at enhancing respiratory function and activity post-stroke.

Main Methods:

• Searched for studies on structured, repetitive respiratory interventions.
• Assessed trial quality using the PEDro scale and risk of bias.
• Conducted meta-analyses on outcomes including respiratory strength, lung function, dyspnea, and activity.

Main Results:

• Respiratory muscle training significantly improved maximal inspiratory and expiratory pressures, FVC, FEV1, PEF, reduced dyspnea, and enhanced activity.
• No significant effects were found for breathing exercises on lung function.
• Meta-analyses could not be performed for aerobic, postural exercises, or electrical stimulation.

Conclusions:

• Respiratory muscle training is effective in improving respiratory strength, lung function, and activity after stroke.
• Evidence is insufficient to support or refute the efficacy of aerobic, breathing, postural exercises, or electrical stimulation for respiratory improvement post-stroke.
