Abstract
Rationale: Modern prostheses require a high level of myocontrol. Hence, knowledge about characteristics of training that improve myocontrol might be helpful for amputees to increase their control of these prostheses. Virtual training methods could provide the same results as training with an actual prosthesis, but can be applied earlier (important for skill acquisition and motivation) and could be used for training and testing of myocontrol ability before acquiring an actual prosthesis. Although virtual training methods have been shown to produce positive effects on myocontrol, it is currently unknown which type of virtual training has the best results. Objectives: The main aim of the study was to determine which of three imposed virtual training methods produced the largest learning effect on discrete and continuous myocontrol. As a secondary aim, we examined the relation between myocontrol and manual dexterity tests. Methods: We measured 36 able-bodied right handed participants (18 male, 18 female), randomly assigned to 1 of 3 training groups. Participants trained their myocontrol on three consecutive days with either a videogame, myosignal feedback or a virtual myoelectric hand. One half of the participants trained with their dominant-side, the other half with their non-dominant side. At the start of the first day and after training of the third day, participants performed tests to determine the level of discrete (opening and closing a virtual prosthetic hand at 3 velocities) and continuous (following a line with the myosignals) myocontrol, and performed two dexterity tests (grip-force control and a fine motor control pinboard task). Results: The myocontrollearning effect was independent of the training methods on both discrete and continuous myocontrol. Findings on the discrete and continuous data showed both tests to contain different effects, indicating that both tests were different. Manual dexterity tests showed no relation to myocontrollearning ability. Conclusion: Learning myocontrol through virtual training is independent of the training method. Future research on myocontrol should take discrete and continuous myocontrol into account as being different aspects of myocontrol. Further research should be done on the relation between motor- and myocontrol to determine individual differences in learning capacity beforehand.
