Background: Carpal tunnel syndrome is the most common entrapment neuropathy of the median nerve at the wrist. In general population CTS is known to be a very common disease and the prevalence of CTS is estimated to be 2.7% as confirmed by clinical and electrophysiological findings. Typical symptoms of CTS are tingling, numbness and parasthesia in thumb, index, middle finger and radial half of ring finger which is often exaggerated at night. Previously research studies have been done on pain control, grip strength, wrist function. Very little research work has been done on effect of exercise on NCS of CTS patients. So the aim of the study is to find the short term (6weeks) effects of exercise on NCS of CTS patients. Methodology: Bilateral sensory and motor nerve conduction studies were carried out in 50 CTS patients before and after 6weeks of exercise. Exercise treatment was given to patients under the guidance of trained physiotherapist. Clinical examination was also done after 6 weeks. RMS machine from Chandigarh was used. Statistical analysis was done by INSTAT- 3.6 software. Result: DML, DML (diff.) DSL, DSL (diff.) showed significant decrease after 6 weeks of exercise in symptomatic (Rt.) hand, but no significant difference was found in SCV, CMAP, SNAP of median nerve. Whereas in Lt. hand only DML (diff.) between median and ulnar nerve showed significant change. There was also improvement in clinical signs and symptoms and pain scale. Conclusion: It was concluded that exercise treatment for 6 weeks under the proper guidance of trained physiotherapist showed significant improvements in clinical as well as electrophysiological parameters in symptomatic hands. So, exercise treatment can be suggested as choice of treatment for CTS patients.
