Intermanual transfer may improve prosthetic handling and acceptance if used in training soon after an amputation.Objective. This effect may improve rehabilitation of patients with an upper-limb amputation.Ībstract = "Background. Intermanual transfer was present in the affected arm after training the unaffected arm with a myoelectric prosthesis simulator, and this effect did not depend on laterality. The training utilized participants who were able-bodied in a laboratory setting and focused only on transradial amputations.Ĭonclusions. We did not find a difference in intermanual transfer between the dominant and nondominant arms. No statistically significant differences were found between groups with regard to initiation time and force control. This finding is indicative of faster handling of the prosthesis. The movement time decreased significantly more in the experimental group (F-2,F-92=7.42, P=.001, eta(2)(G)=.028) when compared with the control group. Initiation time was defined as the time from starting signal until start of the movement, movement time was defined as the time from the beginning of the movement until completion of the task, and force control was defined as the maximal applied force on a deformable object. Half of the participants were tested with the dominant arm and half with the nondominant arm. Training was performed with the unaffected arm, and tests were performed with the affected arm (the affected arm simulating an amputated limb). The control group only performed the tests. To determine the improvement in skill, a test was administered before, immediately after, and 6 days after training. The experimental group performed a training program of 5 days' duration using the prosthesis simulator. A total of 48 right-handed participants (25 women, 23 men) who were able-bodied were randomly assigned to an experimental group or a control group. A mechanistic, randomized, pretest-posttest design was used. The purpose of this study was to determine whether intermanual transfer effects can be detected after training with a myoelectric upper-limb prosthesis simulator.ĭesign.
