Abstract
Developing empirical approaches to functional rehabilitation during the acute and sub-acute stages following amputation remains an area of need. For persons with unilateral limb loss, interlimb training (ILT) is a potentially attractive approach, as it may allow for prosthesis use learning on the unaffected side while awaiting fitting with the prosthesis on the affected side. Understanding the possible benefits of ILT for functional adaptation with prostheses will be beneficial to our understanding of its utility, particularly across levels of upper-extremity amputation. Persons with sound limbs performed simple and complex reach-to-grasp tasks while wearing either a transradial or partial-hand prosthesis simulator in a 5-day ILT paradigm. We hypothesized that participating in ILT would result in motor improvements, particularly for partial hand device use and during increased task complexity. ILT yielded modest effects for both groups, showing significant increases in reach peak velocity, while only partial-hand users showed decreases in reach duration. Overall, the most notable and consistent effects were seen in partial hand users. These results suggest interlimb training may provide tangible benefit as an indicator of future prosthesis adaptation during early-stage amputation rehabilitation, especially with partial hand loss.
