The purpose of this study was to evaluate, through a series of cases, the relationship between the adverse neural tension of median nerve (ANTm) and the electrophysiological involvement in 38 patients with symptoms of the carpal tunnel syndrome (CTS), submitted to nerve conduction studies (NCS). The main measures had been ANTm (in degrees) obtained through the test of neural tension pro v o c a t i o n (TNTP) and parameters of the NCS, divided into three groups: normal, without severe electro p h y s i o l o g i c a l alteration and with severe electrophysiological alteration. Significant correlations were found between ANTm and parameters of the NCS (p<0.05), as well as between ANTm and the three groups defined by the
electrophysiologic alteration (rs=+0.437, p=0.002). The TNAm values were significantly higher in the arms with electrophysiologic diagnoses (p=0.007). It is suggested that the ANTm does have a participation in the physiopathology of the CTS, and the useof therapeutical pro c e d u res that diminish the development of neural tension.
