Comparison of Efficacies of CMR, CMU, CPW & WIF in Diagnosis of Mild Carpal Tunnel Syndrome

The purpose of this study was to compare three sensory and mixed NCS technique in mild CTS hands and evaluate the percentage of abnormality when at least one of them was abnormal. This study is a simple randomized comparative experimental study. This study was carried out in the Electromyography laboratory (E.M.G Lab), Department of Neurosciences, College of Physiotherapy, PIMS, Loni. Carpal tunnel syndrome is the most commonest entrapment neuropathy. The carpal tunnel is bounded by carpal bones and transverse ligaments, which are attached to Scaphoid, Trapezoid and Hamate bones. The diameter of carpel tunnel is 2-2.5 cm and the median nerve passes through it along with 9 digital flexor tendons. Some degree of compression of median nerve and focal nerve conduction slowing is common at this level, which is more pronounced 2-3 cm distal to the origin of the ligament. Autopsy study has also confirmed focal abnormality in the median nerve in 5 out of 12 asymptomatic subjects.
