Individuals with unilateral transtibial amputation exhibit reduced accuracy, precision and consistency during a targeted stepping task

This study compared the accuracy, precision and consistency of unilateral transtibial amputees (UTAs) stepping in to a floor-based target against able-bodied participants. UTAs exhibited reduced precision and consistency during the task, meaning they may find required changes in foot placement inherently more difficult during activities of daily living due to; 1) reduced proprioceptive feedback, 2) control of the prosthetic limb during single stance and 3) being mechanically less stable at the residuum/socket interface.
