Table 3 Percent overlap values for contact pairs within two spiral nerve cuff electrodes. Caption: The percent overlap of recruited motor unit populations for pairs of contacts within spiral cuffs on the femoral nerves of Subjects 07 and 08. Overlap was calculated after 6.3 years for Subject 07 and after 4.2 years for Subject 08. An overlap value of 0% indicates that the two contacts activate completely independent motor units
