2. Fig 1
The typical trace of 1 patient walking at .55m/s. (A) The knee angular displacement (d), (B) knee angular speed (s), (C) net knee joint moment (m), (D) knee joint power (p), and (E) vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF), and rectus femoris (RF) activation time are presented as a function of gait cycle time (in percent). Grey areas represent values (mean ± SD) of healthy subjects walking at .55m/s. Dashed grey lines and solid black lines represent, respectively, pre– and post–BTX-A data of the patient. The vertical dashed line symbolizes the transition between the stance and swing phases. Arrows show key data selected for each variable in all patients on every assessment. Abbreviation: SL, slope of the linear regression fitted to the knee angular speed between s1 and s3.
