Fig. 1

Measurement setup and the mechanical responses to a torque perturbation. Plots depict: (A) setup of the wrist in the handle of the Wristalyzer; (B) the torque perturbation introduced by the Wristalyzer; (C) response torque produced by the participant’s wrist and; (D) the introduced wrist angle. For legibility in this figure, signals are depicted as partial recording between 10–20 s seconds and Butterworth low-pass filtered at 3 Hz
