3-2-12. Size index revisited: Verification by increased number of subjects

Size Index (SI) is a motor unit potential (MUP) parameter in concentric needle EMG, which can sensitively discriminate between control and neurogenic MUPs. We also proposed the revised SI (rSI) using a logarithmic scale for area/amp. In this study, we greatly increased the number of patients, and investigated the utility of SI and rSI for both neurogenic and myogenic MUPs. The biceps brachii (BB) and tibialis anterior (TA) muscles were investigated. The study population was 1619 control MUPs (26 subjects), 340 neurogenic MUPs (10 subjects), and 498 myogenic MUPs (14 subjects) in BB, and 1245 control MUPs (23 subjects), 566 neurogenic MUPs (19 subjects), and 473 myogenic MUPs (13 subjects) in TA.
