One of the methods for CTS diagnosis is to compare distal motor latencies between median and ulnar nerves. In the previous research distal motor latency (DML) of ulnar nerve was recorded from hypothenar area and the median nerve DML was recorded from thenar. In this research we recorded DML of ulnar nerve from thenar area and compared it with DML of median nerve. The aims of this research is to shorten the process of electro diagnosis by preserving the sensitivity. The type of the research is diagnostic clinical trial on 42 normal person and 64 patients with CTS that referred to department of physical medicine and rehabilitation of Shohada Tajrish Hospital in fall and winter of 2000-01 participated in this research. The result of the research is analyzed by student T-test method. The DML of ulnar nerve recorded from thenar in normal persons was 3.52±0.5 ms and the difference between median and ulnar nerve recorded from thenar was 1.23 ms. The P-value of the study were less than 0.0001 that is significant thus this method can be used for diagnosis of CTS.

Background&Objective: Carpal tunnel syndrome is the most common entrapment neuropathy which causes smuch morbidity for patients. Corticosteroid injection is a conventional way to treat CTS. This study was done to compare the wrists verses palm methyprednisolone injection for treatment of carpal tunnel syndrome. Materials&Methods: In a prospective and double blind study, 64 patients who had mild to moderate CTS based on clinical and electerophysiological findings were classified into two groups, the first group received traditional injection technique, the injection site is on the volar wrist surface just proximal to the distal wrist crease between the palmaris longus and flexor carpi radialis tendons. But the second group was injected by new technique. The injection site is about midpalmar area. The patients were followed for one month. Results: Mean rise in nerve conduction velocity (NCV) was 4.00 m/s and 12.03 in the first (wrists method) and second (palm method) groups. Pain score based on visual analog scale decreased 2 sacle unit in both groups similarly. Conclusion: We found 3 times increased at sensory nerve conduction velocity compare to traditional method. This new injection method had better effect on sensory nerve conduction velocity compared to old one so it seems that it can be an alternative way for treatment of CTS.

Background and Objective: Carpal Tunnel Syndrome is the most common compression neuropathy which can cause mild, moderate and sever disability in patiens hands. The first standard treatment is to use Cock-up splint. This study was done to compare therapeutic effects of long (With MP Joint restriction) and short (without mp Joint restriction) Cock-up splint patients with Carpal Tunnel Syndrome. Materials and Methods: In this clinical trail study was done on 23 patients with mild and moderate Carpal Tunnel Syndrome in Shafa Yahyayian Hospital, Tehran, Iran. The diagnosis of Carpal Tunnel Syndrome in patients confirmed with electrodiagnostic method. In this study 23 Patients was treated with long & short cock-up splint in two groups. Group A (12 Patients) was treated by long Splint and group B (11) Patients was treated by short Splint for 4 weeks. Patients was evaluated by Semmes –Wein stein monofilaments, Two Point discrimination, Visual analog Scale (VAS), pinch and Grip Strength. Results: Both types of splints appear to be effective in decreasing CTS symptoms but long Splint more beneficial than Short splint. The results of SWMS, 2PD, Pinch & grip Strength in group A had higher significant difference than group B. (P<0.05). Two groups did not have significant difference in results of severity of pain according to VAS. Conclusion: This study revealed that long Cock-up Splint in comparision with short Cock-up splint demonestrate high efficasy in improving the signs of Carpal Tunnel Syndrome.

Background and Objective: Carpal tunnel syndrome (CTS) is one of the most common disease among the entrapment neuropathies. The purposes of this study was to compare the efficacy of a new dorsal wrist splinting versus common palmar splinting for CTS based on sensory nerve conduction measurements. Materials and Methods: This single blind randomized control trial study was carried out on 22 idiopathic CTS patients. Subjects were randomly divided in two groups: Dorsal splint group (n=12) and palmar splint group (n=10). Both groups used splints for 4 weeks. Sensory conduction study of median nerve were done initially for having baseline and after 4 weeks follow up. SPSS-16 and Kolmogorov–Smirnov, independent T, and paired T tests were used for analysis of Data Results: After four weeks median nerve sensory distal latency and conduction velocity improved significantly in both groups (P<0.05). There was significant difference between both groups due to electro-diagnostic improvement. Conclusion: This study showed that based on electro-diagnostic method, dorsal wrist splint is more effective than cockup splint in carpal tunnel syndrome.
