“…[ 1 – 4 ] Like the current study, these studies were executed by able-bodied subjects using a prosthesis simulator, and although the intermanual transfer effects were not large, they seemed robust. Recently, the intermanual transfer effect was also demonstrated in persons with an amputation[ 5 ]. The effect of intermanual transfer training was not found in the present study, but we did find an interaction effect for test, task, and training group.…”

“…The rationale for using intermanual transfer in prosthetic training is that training can start early in rehabilitation and, as a result, might improve handling and acceptance of the prosthesis. [ 10 – 12 ] Even though the transfer effect has previously been shown in prosthetic training in able-bodied[ 1 – 4 ] as well as in persons with an amputation[ 5 ], the effect was found to be rather small. This study ( Fig 1 ) aims to ameliorate the intermanual transfer effect in prosthetic training by additionally stimulating plasticity processes employing mirror therapy and motor imagery.…”

The effect that a motor skill trained on one side can lead to improvement in the untrained side is called intermanual transfer. Intermanual transfer can help enhance upper limb prosthetic training. To determine the influence of mirror therapy and motor imagery on intermanual transfer in upper limb prosthesis training, a pseudo-randomized clinical trial, single blinded, with a pre-posttest design was used. Forty-seven able-bodied, right-handed participants were pseudo-randomly assigned to two training groups and one control group. One training group undertook an intermanual transfer training program, using an upper-limb prosthetic simulator with added mirror therapy and motor imagery. The second training group completed only the intermanual transfer training program. The control group completed a sham training: a dummy training without using the prosthesis simulator. The program lasted five consecutive days. To determine the improvement in skill, a test was administered before, immediately after, and six days after the training program. Training used the “unaffected” arm; tests were performed with the “affected” arm, resembling the amputated limb. Movement time, the time from the beginning of the movement until completion of the task; hand opening, the duration of the maximum prosthetic hand opening; and grip-force control, the deviation from the required force during a tracking task. No intermanual transfer effects were found: neither the intermanual transfer training program, nor the additional mirror therapy and motor imagery affected prosthesis skills. A limitation of the study was that the training program was applied to able-bodied subjects instead of patients with an amputation. Contrary to previous studies, no intermanual transfer effects were found. Additional mirror therapy and motor imagery did not ameliorate intermanual transfer effects.

“…Nevertheless a recent study showed that experienced prosthesis users show intermanual transfer effects from the use of the prosthesis on the affected side when using a prosthetic simulator on the unaffected side. Importantly, this study shows that the transfer between the simulator and the actual prosthesis is possible [ 12 ].…”

“…Movement times diminished more in the training group than in a control group [ 6 – 8 ], whereas the control of grip-force training showed no transfer effect. Recently, transfer of prosthetic skills between arms was shown for experienced myo-electric prosthesis users [ 12 ]. Movement times of myoelectric prosthesis users, using a prosthetic simulator on the unaffected hand, were shorter, and these users had significantly higher Box and Block Test scores and shorter duration of maximum hand opening than age-matched controls.…”

Intermanual transfer, the transfer of motor skills from the trained hand to the untrained hand, can be used to train upper limb prosthesis skills. The aim of this study was to determine the relation between the magnitude of the intermanual transfer effect and the type of training task. The used tasks were based on different aspects of prosthetic handling: reaching, grasping, grip-force production and functional tasks. A single-blinded clinical trial, with a pre-posttest design was executed. Seventy-one able-bodied, right-handed participants were randomly assigned to four training and two control groups. The training groups performed a training program with an upper-limb prosthesis simulator. One control group performed a sham training (a dummy training without the prosthesis simulator) and another control group received no training at all. The training groups and sham group trained on five consecutive days. To determine the improvement in skills, a test was administered before, immediately after, and one week after the training. Training was performed with the ‘unaffected’ arm; tests were performed with the ‘affected’ arm, with the latter resembling the amputated limb. In this study half of the participants trained with the dominant hand, while the other half trained with the non-dominant hand. Participants executed four tests that corresponded to the different training tasks. The tests measured the reaching (movement time and symmetry ratio), grasping (opening time, duration of maximum hand opening, and closing time), grip-force production (deviation of asked grip-force) and functional (movement time) performance. Half of the participants were tested with their dominant arm and half of the participants with their non-dominant arm. Intermanual transfer effects were not found for reaching, grasping or functional tasks. However, we did find intermanual transfer effects for grip-force production tasks. Possibly, the study design contributed to the negative results due to the duration of the training sessions and test sessions. The positive results of the grip-force production might be an effect of the specificity of the training, that was totally focused on training grip-force production. When using intermanual transfer training in novice amputees, specific training should be devoted to grip-force.
