Upper limb motor function of patients with post-stroke hemiplegia is important for their independence in carrying out activities of daily living. Recently, research and development of upper limb rehabilitation robots to support reach training has been progressing. This robot training has been shown to be effective in improving motor function of the upper limb. However, because many of the robots are expensive and cumbersome, the venues in which such robots could be used were limited to hospitals and nursing care centers. We have developed a reaching device that is highly portable and easy to use at home. The main purpose of this study was to determine the effects of training with the reaching device in patients with chronic stroke hemiplegia. Nine subjects with hemiplegia participated in reach training two days per week for five weeks using the reaching device. We evaluated the results using Fugl-Meyer Assessment (FMA) and co-contraction between biceps brachii and triceps brachii muscles using the Co-Contraction Index (CCI). The results of FMA showed a significant increase in score after reaching training. On the other hand, no significant difference between pre-and post-training CCI scores was observed. The results showed that reach training was effective in improving comprehensive upper limb motor function. However, further investigation is needed to examine this in greater detail. In the future, it is necessary to identify subjects who respond to the training. The development of this reaching device has the potential to provide autonomous and effective home-based rehabilitation for patients with post-stroke hemiplegia.
