This study was conducted to compare the effects of high frequency and low frequency transcutaneous electrical nerve stimulation applied to gastrocnemius muscle on proprioception, spasticity, and dynamic balance of
stroke patients. Twenty subjects were randomly assigned to each of 10 experimental and control groups. High frequency transcutaneous electrical nerve stimulation was applied to the experimental group and low frequency transcutaneous electrical nerve stimulation was applied to the control group for 20 minutes per day, 5 times a week for a total of 4 weeks. The subjects were assessed for proprioception by joint position sense in
ankle plantarflexion and dorsiflexion, spasticity was assessed using Modified Ashworth Scale (MAS) and amount of resistance, and dynamic balance was assessed using the Timed Up and Go (TUG) test. A significant
improvement in joint position sense (plantarflexion, dorsiflexion), MAS, amount of resistance, and TUG was observed after intervention in the experimental group (p < 0.05), and there was a significant improvement in all
evaluation items compared to the control group (p < 0.05). The results of this study suggest that application of high frequency transcutaneous electrical nerve stimulation to the bilateral gastrocnemius muscles of patients
with stroke has a positive effect on proprioception, spasticity and dynamic balance.
