Study On Relationship Between TCM Syndrome Of Carpal Tunnel Syndrome And Neurophysiological Features

Objective:This paper discusses the relationship between different TCM types of CTS patients and their neurophysiological indices by analyzing the differences between the related neural electrophysiology indices of CTS patients and their different TCM types, so as to set up theoretical basis for TCM dialectical of CTS.Methods:According to the normal diagnostic criteria and electrophysiology diagnostic criteria of CTS,60 cases with CTS were selected. Then according to TCM types differentiations grouping, these 60 cases were divided into two groups, namely syndrome of cold-dampness blocking collaterals group (group A), dual deficiency of qi and yin group (group B). Another 20 healthy volunteers with no peripheral nerve disorders were selected as group C. Routine electromyography testing were carried out on the Danish KEYPOINT electromyography to detect median nerve, ulnar nerve, including motor nerve conduction velocity (MCV) and amplitude of compound nerve action potentials (CMAP), sensory nerve conduction velocity (SNCV) and amplitude of sensory nerve action potential (SNAP), distal motor latency (DML), F-wave occurrence rate and latency of median nerve. All test results of different TCM types were compared with statistical methods among different groups to explore the correlation between electrophysiological and TCM types.Results:(1) Compare the SNCV and CMAP and DML of median nerve of group B with group A, it is clear that SNCV of the median nerve of group B are slower than group A, while CMAP decreased gradually, and DML extended, (P<0.05). Compared with the group C, the SNCV of the median nerve of both group A and group B are slower, while CMAP both decreased and DML both reduced. There exist obvious differences between any two groups among the three groups in statistics (P<0.05). (2) Compare group B with group A, MCV of the median nerve of group A are slower (P<0.05). Compared with the group C, the MCV of the median nerve of both group A and group B are slower. There exist obvious differences between group B and C in statistics (P<0.05), but no obvious differences between group A and C (P>0.05). (3) Compare the control group (group C), for both SNCV and DML of ulnar nerve with patients groups (group A and group B), it is clear that there were no significant differences (P>0.05) between the control group and the patients groups.Conclusion:There exist correlations between different TCM types of Carpal tunnel syndrome patients and their median nerve electromyography. he correlations between, There exist obvious differences for SNCV, MCV, CMAP, and DML among three groups, and these differences provide objective reference for TCM differentiations on CTS.
