Modified BATRAC exercise apparatus. A: the modified BATRAC exercise apparatus. The apparatus allows movements in the horizontal plane only. The rotation axis of the wrist is aligned with that of the manipulandum B: a feedback screenshot. On the left, left-hand position by right-hand position (white) and ideal line of movement are depicted. On the top-right the amplitudes for flexion and extension for both hands separately are given. On the bottom right the relative phase and its variability for flexion and extension are presented.
