Abstract
Objectives
To determine intermanual transfer effects in patients with a below-elbow amputation
using a myoelectric prosthesis and to establish whether laterality affects these effects.
Design
Case-control.
Setting
A standardized setting in a rehabilitation clinic.
Participants
A convenience sample (N=44) of experienced myoelectric prosthesis users (n=22) and
matched controls (n=22). Controls were matched on sex, age (±5y), and hand dominance.
Interventions
Both the experienced group and the control group performed several tasks using a prosthesis
simulator attached to their nonaffected arm.
Main Outcome Measures
Movement time, force control, Box and Block test (BBT) scores, and duration of hand
opening.
Results
Movement times of myoelectric prosthesis users were shorter, and these users had significantly
higher BBT scores and shorter hand opening durations than those of controls. No intermanual
transfer effects on force control and no laterality effects were found.
Conclusions
Intermanual transfer effects were present in experienced myoelectric prosthesis users
with a below-elbow amputation, independent of laterality. These findings support the
clinical relevance of intermanual transfer training, which may facilitate persons
with an upper limb amputation to start training directly after the amputation.
