| dc.title | Effects of transverse carpal ligament compression on nerve conduction findings in patients with carpal tunnel syndrome | en_US |
| dcterms.abstract | This study was conducted in a clinical setting of a regional hospital. This research aimed to examine the influence of transverse carpal ligament compression on nerve conduction studies in patients with carpal tunnel syndrome (CTS) in order to determine the value of adding the compression provocative maneuver to the conventional nerve conduction test in the electrodiagnosis of carpal tunnel syndrome. Three groups of CTS patient with different seventies: suspected (early), mild and moderate were studied. Direct transverse carpal ligament compression was applied by a force device at a constant pressure level of 7.3 PSI for five minutes. Conduction latencies of median and ulnar nerves were recorded before and within one minute after the compression. Data was analyzed with one-way ANOVA to compare baseline conduction latencies between the test groups. The paired t-test was used for comparing the measured values for the pre- and post-compression. The results showed that all test groups had statistical significant (p>0.05) difference in the pre-and post- latency measurement of median nerve. The provocative compression elicited a bigger change in the moderate CTS group than that in the suspected and mild patient groups, with a maximum change of 0.27 ms was produced in the moderate CTS group, Moreover, there was a 5% increase in the latency after the compression for all CTS groups with a linear relationship (Pearson r=0.98). However, these results were not clinically significant as the change in the latency was insufficient to meet the clinically meaningful criteria of 0.3ms as suggested in literatures. Although this study could not conclude that the effect of transverse carpal tunnel ligament compression on the nerve conduction test was clinically significant, the results have demonstrated a significant difference in the changes in conduction latency for all subject groups between pre- and post- -compression. A linear relationship has also been shown for all subjects, which included normal subjects and subjects with different CTS seventies. | en_US |
