Comparisons of PC loading values associated with EMG activity from TA and Sol in Intact rats and both injury groups

Group	Ds	Lv	Us
Intact	1, 2	1, 2	1, 2
UT 10 wk	NS	NS	NS
ChABC 10 wk	NS	NS	NS

Comparisons of principal component (PC) loading values associated with EMG activity from tibialis anterior (TA) and soleus (Sol) in Intact rats and both injury groups at 10 wk postoperatively and at each slope. Ds, downslope; Lv, level; Us, upslope. Factor loadings for EMG profiles from TA vs. Sol were compared statistically [least significant difference (LSD) post hoc tests]. The presence of a “1” and/or a “2” means that the difference in the PC1 and/or PC2 factor loadings, respectively, was statistically significant (P ≤ 0.05). If they were not statistically significant on either factor, then “NS” (i.e., not significant) occupies the cell.
