Mirror therapy in chronic stroke survivors with severely impaired upper limb function: a randomized controlled trial

Area of Science:

• Neurorehabilitation
• Stroke Recovery
• Motor Function Restoration

Background:

• Mirror therapy (MT) is explored for mild to moderate stroke impairments.
• Previous research on MT for severe upper limb paresis in chronic stroke is limited.
• This study investigates MT's efficacy in chronic stroke with severe upper limb deficits.

Purpose of the Study:

• To evaluate the effectiveness of mirror therapy (MT) versus passive mobilization.
• To assess MT's impact on chronic stroke survivors with severe upper limb impairment.

Main Methods:

• Randomized controlled trial with 31 chronic stroke participants.
• Experimental group received MT; control group received passive mobilization.
• Interventions included 24 sessions over 8 weeks; assessments pre- and post-intervention.

Main Results:

• Both groups showed motor function improvements on the Wolf Motor Function Test.
• No significant differences in kinesthesis or stereognosis were found.
• MT group demonstrated significant improvement in light touch sensitivity.

Conclusions:

• MT may offer limited motor benefits but enhances light touch sensitivity in chronic stroke with severe upper limb impairment.
• MT is a viable therapeutic option for addressing tactile deficits in this population.
• MT complements passive mobilization for upper limb rehabilitation post-stroke.
