FIGURE 1.
A and B, BBB locomotor rating scores and body mass change from before surgery (pre-sx) in rats that received T9 laminectomy alone (SHAM), T9 laminectomy plus SCI, SCI with qBWSTT (SCI + qBWSTT), or SCI with passive-isokinetic bicycle training (SCI + Cycle). Values are estimated marginal means ± SEM, n = 12–16/group. Some error bars are within the size of the symbol. † indicates difference vs pre-sx, and letters indicate difference vs respectively labeled groups (a = vs SHAM, b = vs SCI, c = vs SCI + qBWSTT, and d = vs SCI + Cycle) at P < 0.05 or *P < 0.01. Note: Horizontal dashed line (A) indicates the threshold for voluntary overground weight-supported plantar stepping (i.e., BBB ≥ 9). SCI animals that exceeded a priori criteria were excluded before analysis. Complete statistical findings are in Supplemental Table 2 (Supplemental Digital Content, Statistical outcomes and treatment effects for variables assessed at multiple time points, http://links.lww.com/MSS/C771).
