Angle and torque: ankle angle (left) and ankle torque (right) for the mean of multiple strides using the Walk-Run ankle (red) and the mean of up to 21 able-bodied reference subjects (gray). For the reference data also standard deviation is shown. Data is presented for the gait cycle of 1.6 m/s walking, 2.6 and 4.0 m/s running. The take off of the reference is indicated by a vertical line. An increase of the ankle angle implies plantarflexion
