Long-term patient observation after conservative treatment of carpal tunnel syndrome: a summary of two randomised controlled trials.

BACKGROUND

Physiotherapy of carpal tunnel syndrome (CTS) involves manual therapy based on neurodynamic techniques. Until now, two randomized controlled trials have shown that immediately after therapy, CTS patients who received neurodynamic techniques had significant improvement in nerve conduction, pain, symptom severity (SSS), functional state (FSS), muscle strength (MS) and two-point discrimination (2PD). However, long-term effects seem to be more important, as they are the only ones that can significantly improve the patient's health and influence economic and social costs. Thus, the objective of this study was to evaluate the long-term (six months) effects of neurodynamic techniques in the conservative treatment of CTS patients.

METHODS

Carpal tunnel syndrome patients (107) from two previously published randomised clinical trials were observed for six months after the treatment based on neurodynamic techniques.

RESULTS

The sensory conduction velocity, motor conduction velocity, and motor latency were not subject to statistically significant changes within six months after therapy ( > 0.05). In both groups, there was further pain reduction ( < 0.05). In Group B, the symptom severity improved significantly ( < 0.05), while the functional status in both groups remained unchanged ( > 0.05). In both groups, there was muscle strength improvement ( < 0.05). Two-point discrimination remained unchanged six months after the therapy.

CONCLUSION

The use of manual therapy based on neurodynamic techniques maintains the beneficial effects 6 months after therapy in CTS patients.
