Mirror therapy for improving lower limb motor function and mobility after stroke: A systematic review and...

Area of Science:

• Neurorehabilitation
• Physical Therapy
• Stroke Recovery

Background:

• Mirror therapy is a proposed intervention for lower limb rehabilitation following stroke.
• Stroke commonly results in lower limb deficits affecting motor function, balance, and mobility.

Purpose of the Study:

• To systematically review and meta-analyze the effectiveness of lower limb mirror therapy in stroke patients.
• To assess its impact on muscle tone, motor function, balance, ambulation, walking velocity, ankle range of motion, and gait characteristics.

Main Methods:

• Systematic review and meta-analysis of nine included studies.
• Standardized Mean Differences (SMD) and Mean Differences (MD) were used for effect size calculation.
• Comparison against sham and non-sham interventions.

Main Results:

• Significant positive effects of mirror therapy were found for motor function (SMD 0.54).
• Significant improvements were observed in balance capacity (SMD -0.55), walking velocity (SMD 0.71), and passive range of motion for ankle dorsiflexion (SMD 1.20).
• A trend towards improvement in step length was noted (SMD 0.56).

Conclusions:

• Mirror therapy may positively impact lower limb deficits in stroke patients.
• The findings suggest potential benefits for motor function, balance, and mobility.
• Methodological limitations in the included studies necessitate a cautious interpretation of the results.
