AI Article Synopsis
- * A systematic review and meta-analysis were conducted, including eight articles, where biofeedback showed significant benefits in improving knee extension and balance, with two out of three studies indicating better quadriceps strength in the biofeedback group.
- * While biofeedback appeared helpful for strength and functionality, there was no significant difference in pain levels or the Lysholm score between patients using biofeedback and those in the standard rehabilitation group.
Article Abstract
Background: Rehabilitation following anterior cruciate ligament (ACL) reconstruction surgery is essential to regain functionality and return to previous activity level. Electromyographic biofeedback may be an effective intervention for rehabilitation of patients following ACL surgery.
Objective: To synthesize the available evidence on the effect of electromyographic biofeedback in the treatment of quadriceps strength following ACL surgery.
Design: Systematic review with meta-analysis.
Data Sources: PubMed, EMBASE, CENTRAL and Epistemonikos were searched.
Eligibility Criteria: Randomized clinical trials with patients undergoing ACL reconstruction surgery comparing biofeedback with a standard rehabilitation control group.
Data Extraction And Data Synthesis: Two authors selected articles and performed data extraction. The analysed outcomes were strength, function, pain, knee extension and balance. The risk of bias of individual studies was assessed using the Cochrane Risk of Bias Tool. Results were combined through random-effects meta-analysis, reporting mean differences.
Results: Eight articles were included in the qualitative analysis, and four articles were included in the quantitative analysis. The interventions lasted between 4 and 12 weeks. Three studies evaluated the effect of biofeedback on quadriceps strength; of these, two studies showed a significant difference in favour of the biofeedback group. In addition, biofeedback was found to improve knee extension [standardized mean difference - 1.3, 95% confidence interval (CI) - 1.74 to -0.86] and balance (one study). There was no significant difference in Lysholm score (mean difference -6.21, 95% CI -17.51 to 5.08; I =59%) or pain between the biofeedback group and the control group.
Conclusion: Electromyographic biofeedback in knee rehabilitation could be useful following ACL reconstruction surgery.
