Prosthesis sensor data versus stride time. (A) Prosthetic joint angle in time (normalized to stride period). Stride period in this and other time-series charts begins and ends at prosthesis heel contact. (B) Total prosthesis torque (i.e. Spring-torque + Time-torque). (C) Prosthetic ankle power. Curve colors correspond to Time-torque onsets. Black curve is Spring-like condition. Horizontal bars indicate Time-torque period. Vertical dashed lines indicate mean timing of intact-side heel contact and prosthesis toe off.
