Upper extremity function and disability recovery with vibration therapy after stroke: a systematic review and...

Area of Science:

• Neurorehabilitation
• Physical Therapy
• Biomedical Engineering

Background:

• Stroke survivors often experience significant upper extremity motor impairment and functional disability.
• Restoring motor function is crucial for improving quality of life and independence post-stroke.

Purpose of the Study:

• To systematically review and meta-analyze the therapeutic effects of vibration therapy on upper extremity motor impairment, function, and disability recovery in stroke patients.
• To evaluate the efficacy of vibration therapy as a rehabilitation strategy for post-stroke upper limb recovery.

Main Methods:

• A systematic review and meta-analysis adhering to PRISMA guidelines.
• Searched multiple databases (PubMed, EMBASE, Cochrane, PEDro, CNKI, Google Scholar) up to May 31, 2024.
• Included 30 randomized controlled trials (RCTs) involving 1621 stroke patients, assessing outcomes using standardized scales like Fugl-Meyer, Wolf Motor Function Test, and Barthel Index.

Main Results:

• Vibration therapy demonstrated significant improvements in upper extremity motor impairment (SMD=1.19), function (SMD=0.62), and disability recovery (SMD=1.01) compared to control groups.
• Focal vibration therapy showed superior effects on disability recovery (SMD=2.14) versus whole-body vibration (SMD=2.0).
• Interventions of 4-8 weeks and combined therapy with conventional rehabilitation yielded significant benefits.

Conclusions:

• Vibration therapy is a promising and reliable rehabilitation program for enhancing upper extremity motor functions and reducing disabilities in stroke survivors.
• Early initiation of vibration therapy (4-8 weeks) post-stroke is recommended for maximizing therapeutic benefits.
