Abstract Background The double crush hypothesis DCH that had been widely accepted seems to have been dismissed recently. Prior to the DCH retrograde changes in the proximal median nerve in carpal tunnel syndrome CTS were reported. There has been no report of quantitative analyzing about the effect of one site s compression on another site all through the same peripheral nerve in CTS patients. Methods We measured the central motor conduction time CMCT motor conduction latency of the cervical root region CRL peripheral path latency from the rootlet to the wrist PL and motor distal latency MDL in the median nerve and ulnar nerves respectively in CTS patients. Results MDL PL and CRL were prolonged selectively in the median nerve but not in the ulnar nerve of CTS patients. And
