Rehabilitation Practice and Science
The aim of this investigation is to define the normal values and the boundaries of compound muscle action potential (CMAP) dispersion of a specific age group in Chinese population. Measurements were made from median and ulnar motor nerves of 30 normal volunteers, age between 25-35 years. Supramaximal stimulations were applied to wrist, elbow and axilla of median and ulnar nerves individually. Negative peak areas, amplitudes and durations were recorded and the percentage of dispersion were calculated for each parameter. The results show that the percentage of negative duration, amplitude and area decay between wrist and below-elbow stimulation sites are 2.89%, …
