Scatter plot of median nerve SNAP amplitude measured in two study sessions (3-7 days apart). Filled circles are from subjects who had complaint of frequent hand/arm pain or tingling. The intra-class correlation coefficient (ICC) is 0.95 for open circles (nerves from subjects without frequent hand/arm pain or tingling) and 0.93 for filled circles (nerves from subjects with frequent hand/arm pain or tingling).
