Effect of Mechanical Interface Mobilization Technique on Pain and Functional Status in Carpal Tunnel Syndrome

The median nerve gets entrapped in the wrist, causing carpal tunnel syndrome (CTS), the most prevalent peripheral neuropathy in the upper limb. A number of clinical findings, such as sensory issues with the first three digits of the hand sensory distribution of the median nerve, a positive Phalen test, weakness and atrophy of the thenar muscle, and electrophysiological findings (prolonged motor and sensory distal latencies of the median nerve) are used to diagnose CTS . The most frequent occupational risk factors for CTS are repetitive wrist and finger motions or holding uncomfortable wrist positions for extended periods of time. Tenosynovitis of the finger flexors, a thicker transverse carpal ligament, a fracture or dislocation of the distal radius or lunate, rheumatoid arthritis, lipoma, diabetes, and hyperthyroidism are other non-occupational causes . A combination of techniques has been used in the studies of Seradge H. et al and Sucher Benjamin M. Et al which included mechanical interface and neuro-dynamics, but the isolated effects of each method is yet to be determined by further studies as their combined effects are more focused on in the current literature. And that leads to an unclear decision about, which group of manual therapy techniques has better effects on individuals suffering from CTS .
