Effect of the Observation of an Audio-Visual Modeling on the Rehabilitation of Upper Limb Function in Stroke Patients

The purpose of this experiment was to investigate the applicability of audio-visual modeling for im-proving the efficiency of rehabilitative programs by analyzing the effects of observing these various mod-els on the capacity of stroke patients to perform upper limb activities. Twenty-one stroke patients par-ticipated in the experiment and were randomly assigned to either task modeling, sport modeling, or con-trol group. During 2 weeks of intervention，subjects in all groups participated in the physical practice of experimental tasks. These tasks comprised of a Nine Hole Peg Test, the Jebsen-Taylor Hand Function tests, and locomotion. These tasks were performed 5 days a week, 30 min per day. In addition to the physical practice, the task modeling group observed a model performing experimental tasks and locomo-tive activities for 20 min, while the sport modeling group observed a model performing various sport ac-tivities for 20 min. Subjects’ ability to perform the experimental tasks was measured 3 times, before, im-mediately after and 1 week after the intervention. Analyses of the capacity to perform upper extremity activities displayed significant improvement from the pre-test to immediate and delayed post-tests in all groups. However, the amount of improvement was the highest in the task modeling group. The task modeling group was superior to the control group in the post-test of all experimental tasks, whereas the sport modeling group did not display significant differences from the control group. These results suggest that audio-visual modeling can be used as an effective cognitive intervention for facilitating the re-habilitation of stroke patients, and its rehabilitative effect can be maximized when the program is com-prised of performance scenes directly related to the target task.
