FIG. 4

Distribution of CIS for thumb and index muscles measured during an object-hold task. The figure shows mean CIS values (±SE) computed from motor-unit pairs within intrinsic muscles (1), across intrinsic muscles (2), across intrinsic and extrinsic muscles (3), and across extrinsic muscles (4). Data 1–3 refer to the present 2-digit object hold task. Data 4 are from Winges and Santello (2004) (5-digit object hold) and Winges et al. (2006) (2-digit object hold) and are shown for comparison with the results of the present study.
