A lot of rehabilitation devices for fingers are researched, currently. After leaving a hospital, an intervention by therapists decreases significantly. Therefore, the rehabilitation device is required functions not only the rehabilitation but also the automatic evaluation function. In this study, we aim to develop the finger rehabilitation device for home rehabilitation. Especially, in this report, we propose automatic evaluation system of the finger independent movement. Movements from index finger to little finger, are measured by pressure sensors on the prototype we developed. Measured data are used as time-series signals, states of each finger are quantified by calculating dissimilarities between healthy subject signals and patient signals. Finally, an entire finger movement is quantified by integrating all dissimilarities. From the experiment conducted with hemiplegia patients and healthy subjects, we could show the change of the integrated dissimilarity corresponding to the level of the hemiplegia.
