Time to object contact (TTC) for each successful grasp obtained by each patient. TTC represents the time between the onset of hand movement to making contact with the object, defined as the object moving ≥1 mm from its position on the table. The shorter the TTC, the quicker the hand reached the object. Boxes represent median, 25th and 75th percentiles, error bars 5th and 95th percentiles of successful grasps under each prosthesis setting; patched and unpatched data pooled.
