- Target number of participants116
- InterventionsThe trainingsgroup gets a training with a prosthetic simulator for half an hour on 5 consecutive days, while the control group does not get any intervention. The training consist of the Southampton Hand Assessment Procedure. In three tests, for both groups, the execution of tasks is analyzed.
- Primary outcomeDuring three tests, pretest (day 1), posttest (day 5) and retention test (day 11) the movement and initiation time of three functional activities are measured using E-prime. With two deformable objects the force control is measured (the amount of pressure applied).

- Brief summaryPeople with an upper extremity amputation often choose to have fitted a prosthesis to restore the functionality for as best as possible. But the rejection rate of prosthetic devices is high, mainly due to a low degree of functional use (Biddiss & Chau, 2007; Dudkiewicz, Gabrielov, Seiv-Ner, Zelig, & Heim, 2004; Kyberd, Davey, & Morrison, 1998; Plettenburg, 2002). Functional use can be enhanced by training (Carter, Torrance, & Merry, 1969; Lake, 1997; Weeks, Wallace, & Anderson, 2003). To achieve maximum success in prosthetic use it is important to start to train in the first weeks after the amputation (Atkins, 1992; Dakpa & Heger, 1997; Gaine, Smart, & Bransby-Zachary, 1997). However, in these initial stages of rehabilitation the wounds are not healed yet and the prosthesis is not finished. To be able to start training within these initial stages, we propose to use the unaffected limb. With an upper limb prosthetic simulator, as developed earlier in Groningen, training can start with the unaffected hand. It is hypothesised that training the unaffected hand results in a higher starting level and faster learning of the affected hand. This effect is called ‘transfer of learning’ (Hicks, Gualtieri, & Schoeder, 1983; Karni et al., 1998; Kumar & Mandal, 2005; Lee, Hinder, Gandevia, & Carroll, 2010; Mier & Petersen, 2006; Pereira, Raja, & Gangavalli, 2011).
If we indeed establish that this transfer has effect on learning to use a prosthesis, then this might help the rehabilitation after an amputation of the upper limb to become faster and more efficient.
