Abstract: In this study, action observational training was used as afferent sensory input to produce motivational stimuli for movement in stroke patients. Action observational training provides motivation for movement and improves functional movement through imitation and practice of observed movements. Dual-afferent sensory input (DASI), which combines electromyography-triggered functional electric stimulation (ETFES) and action observation, was investigated to determine its effects on voluntary movements in 18 patients with left hemiplegia diagnosed between 6 and 24 months prior. The 9 subjects in the DAS group underwent ETFES with action observation training for 4 weeks (20 minutes a day, 5 days a week), while the 9 control group subjects underwent functional electric stimulation for the same duration. The outcome measures were the movement-related cortical potential (MRCP), H-reflex, electromyography, and balance. The control and DASI groups showed significant increases in MRCP, muscle activity, and balance, while H-reflex was significantly decreased. MRCP and balance showed significant differences between DASI and control groups. Results indicate that DASI stimulates voluntary movement in patients, causes rapid activation of the cerebral cortex, and reduces excessive excitation of spinal motor neurons. Therefore, DASI, which stimulates voluntary movement, has a greater effect on brain activation than a single type of stimulus in the treatment of stroke patients.
