The mixed nerve conduction velocity of the median nerve in the forearm diverged from the motor and sensory nerve conduction velocities and correlated poorly with the severity of carpal tunnel syndrome (CTS) in 61 hands. In contrast, the motor and sensory nerve conduction velocities in the forearm correlated well with CTS severity. The mixed nerve conduction velocity in the forearm is probably determined by nonlesioned fibers such as those from the cutaneous palmar branch of the median nerve. The motor and sensory, but not the mixed nerve conduction velocities in the forearm may be used to estimate possible retrograde impairment in CTS.
在前臂，正中神经的混合神经传导速度与运动和感觉神经传导速度不同，且在61只手中，其与腕管综合征（CTS）的严重程度相关性较差。相比之下，前臂的运动和感觉神经传导速度与CTS严重程度相关性良好。前臂的混合神经传导速度可能由未受损的纤维决定，比如正中神经掌皮支的纤维。前臂的运动和感觉神经传导速度，而非混合神经传导速度，可用于评估CTS中可能存在的逆行性损伤。
