Interventions involving repetitive practice improve strength after stroke: a systematic review

Area of Science:

• Neurorehabilitation
• Physical Therapy
• Stroke Recovery

Background:

• Stroke frequently leads to muscle weakness and functional deficits.
• Repetitive practice is a common rehabilitation strategy aimed at improving motor function.

Purpose of the Study:

• To systematically review evidence on the effectiveness of repetitive practice interventions for improving strength after stroke.
• To determine if strength improvements are linked to functional activity gains.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials.
• Included adults who had experienced a stroke.
• Compared repetitive practice interventions against no intervention or sham interventions.

Main Results:

• Fifty-two studies involving 1928 participants were analyzed.
• Repetitive practice showed a significant positive effect on overall muscle strength (SMD 0.25).
• Improvements were observed in both upper limb activity (SMD 0.15) and lower limb activity (SMD 0.25).

Conclusions:

• Interventions incorporating repetitive practice are effective in improving muscle strength post-stroke.
• Enhanced strength through repetitive practice correlates with improved limb activity and function.
