Clinical Report: Overview and Research Deficiencies in Neuromodulation Approaches for Knee Osteoarthritis Rehabilitation

Overview

This scoping review highlights the current status of neuromodulation techniques for knee osteoarthritis (KOA) rehabilitation and identifies significant research gaps. Various neuromodulation methods have been evaluated in studies, but there is a lack of standardization in intervention protocols.

Background

Knee osteoarthritis is a prevalent degenerative joint disease that significantly impacts quality of life and poses a substantial burden on healthcare systems. Traditional treatment options often yield limited results, leading to interest in neuromodulation as a potential non-pharmacological rehabilitation strategy.

Data Highlights

Key Findings

• 23 studies were included in the review, covering various neuromodulation techniques.
• Techniques evaluated included TENS, NMES, PNS, electroacupuncture, electrical dry needling, tVNS, and tDCS.
• All techniques were reported to have some level of efficacy in pain relief and functional improvement.
• Intervention protocols varied widely among studies.
• Long-term efficacy and mechanisms of action remain inadequately explored.

Clinical Implications

Further research is essential to establish optimal treatment parameters and enhance the understanding of the mechanisms involved.

Conclusion

Significant research deficiencies must be addressed to optimize the clinical application of neuromodulation in KOA rehabilitation.
