140 CHAPTER 7 Electrophysiology Recovery of the CMAP at 12 weeks showed that autograft (57.2 ± 2.9%) was superior to allograft (35.9 ± 3.6%, P<0.001) and SIEF (46.5 ± 2.6%, P<0.05). This same pattern was seen at 16 weeks; the autograft (66.0 ± 3.3%) was superior to the allograft (45.9 ± 4.8%, P<0.01) and the SIEF (53.1 ± 3.1%, P=0.03, Figure 3). Figure 3. Compound muscle action potential (CMAP) at 12 and 16 weeks for the autograft, allograft and the allograft wrapped with a superficial inferior epigastric artery fascial (SIEF) flap. Results are expressed as a percentage of the experimental left side to the unoperated right side (L/R Ratio) and are given as the mean ± SEM. *Indicates significance at P<0.05, ** P<0.01, ***P<0.001). N=10 per group. SEM: Standard error of the mean.
