Stroke patients have limited motor function due to ankle spasticity, and various interventions are applied to solve this problem. The purpose of this study was to investigate the effects of functional electrical stimulation (FES) with ankle exercise on spinal cord motor neuron excitability and balance in stroke patients. Twenty-five stroke patients were divided into the three groups. For the intervention, the control group applied general physiotherapy, the experimental group I applied a sham FES with ankle exercise, and the experimental group II applied a FES with ankle exercise. All groups applied the intervention for 30 min per session, 5 times a week, for a total of 8 weeks. The functional reaching test (FRT), Timed Up and Go test was used to measure balance ability, and H-reflex was used to measure spinal motor neuron excitability. All tests were measured before and after the intervention. In the ankle exercise with FES group, spinal motor neuron excitability significantly decreased (P<0.05), and FRT was significantly increased (P<0.05). Therefore, FES with ankle exercise for stroke patients could be suggested as an effective intervention for improving motor function.
