Abstract

Purpose: The purpose of this study was to investigate the effects of action observation physical training accompanied by rhythmic auditory stimulation on the balance abilities of patients with stroke.

Method: In total, 30 patients with stroke at more than 6 months after the onset of the disease were included in the present investigation. Experimental programs were employed for 30 minutes a day, 3 times a week for 8 weeks. The audiovisual action observation training (AAO) group received action observation training with rhythmic auditory stimulation at a comfortable speed and physical training, and the visual action observation training (VAO) group received action observation training and physical training. The balance was assessed using a Biodex balance system.

Results: In overall balance index, anteroposterior balance index, mediolateral balance index, and fall risk, there were significant improvements in both groups after intervention. A greater degree of changes were observed in the AAO group than those in the VAO group (P< .05).

Conclusions: The simultaneous application of action observation physical training and rhythmic auditory training seems to be an effective treatment method for patients with stroke. Furthermore, it is presented as a more effective therapeutic intervention method for those with motor disorders, such as patients with stroke.
