FIG. 4.
The force–frequency relationships at 2 months (A, C, E) and 4 months (B, D, F). Age-matched cage control (Age) and uninjured contralateral control (Contra) were compared with VML-injured subjects at 2 and 4 months. At both time points, isometric force was significantly less at most stimulation frequencies compared to Contra (p>0.05). However, when force was expressed as percent of Po (E, F), there was no difference between groups at either time point. All values are mean±standard deviation.
