Purpose This study was conducted by randomly assigning patients to a study group and control group to investigate the effects of calf eccentric training on muscle strength, muscle tone, balance and gait variables in stroke patients. Methods The subjects of this study were 26 stroke patients from a single medical institution sho met the study selection criteria. The intervention period was 8 weeks, 3times a week, 30 minutes each. The study group(n=13) applied eccentric training on the paretic side, and the control group(n=13) applied inclined plate training. Heel lifting has been applied. Results There was a significant difference in the strength and tone of the gastrocnemius and soleus muscles before and after intervention, and there was a significant difference in plantar pressure toward the rear. The step length on the paretic side decreased after the intervention, showing a significant difference, and the speed increased after the intervention, showing a significant difference. There was a significant difference in the symmetry index results among the study groups. Conclusion Calf eccentric training was effective in increasing GCM-Soleus muscle strength, reducing muscle tone, and improving balance and walking ability as heel contract increased.
