Summary
Electromyographic biofeedback therapy effectively improves limb function in stroke survivors, particularly in the short term. While shoulder and wrist range of motion increased, long-term benefits require further investigation.
Area of Science:
- Neurorehabilitation
- Clinical Electrophysiology
- Stroke Recovery
Background:
- Upper and lower limb impairment frequently occurs post-stroke.
- The efficacy of electromyographic biofeedback therapy for limb functional rehabilitation remains uncertain.
Approach:
- A systematic review and meta-analysis of randomized controlled trials.
- Searched PubMed, Embase, Cochrane Library, and PEDro up to May 1, 2022.
- Included 10 studies with 303 participants.
Key Points:
- Electromyographic biofeedback therapy significantly improves limb function post-stroke (SMD, 0.44; P = 0.008).
- Short-term effects were significant (SMD, 0.33; P = 0.04), but long-term effects were not statistically significant (SMD, 0.61; P = 0.10).
- Improved active range of motion in shoulder (SMD, 1.49) and wrist joints (SMD, 0.77).
Conclusions:
- Electromyographic biofeedback therapy enhances upper and lower limb function in stroke patients.
- Evidence supports short-term functional improvements, but not long-term benefits.
- Further research is needed to determine optimal treatment parameters and intervention duration.
