The main function of the human hand is to grasp and manipulate objects, with opposing movements of the fingers playing a particularly important role. In recent years, the effectiveness of integrated volitional control electrical stimulator(IVES) devices has been reported as a treatment method for stroke-induced upper limb paralysis. However, most of the reports used IVES on the extensor motion of the hand, with no reports using IVES on the opposing muscles of the hand. The present study combined IVES with task-oriented training for a subacute stroke patient with mild proximal upper limb paralysis who was able to flex and extend his fingers, but had difficulty with opposing hand movements. As a result, improvement in upper limb function was observed, and the patient was able to use a knife. The treatment method using IVES and task-oriented training for the opposing motion of the hand may be a means of improving upper limb function.
