Abstract

Background: Stroke often results in hemiparesis, which leads to asymmetrical plantar pressure and impaired balance control. The gastrocnemius muscle plays a key role in plantar flexion and postural stability. Dysfuncion of this muscle is associated with decreased posterior foot pressure and increased fall risk in stroke patients. Objectives: To investigate the effects of gastrocnemius muscle stimulation using microcurrent stimulation therapy on plantar pressure distribution and functional balance in stroke patients. Design: Randomized controlled trial. Methods: Twenty chronic stroke patients were divided into an experimental group (microcurrent stimulation therapy+conventional rehabilitation therapy) and a control group (conventional rehabilitation therapy only). plantar pressure (posterior foot pressure), center of anteroposterior pressure displacement (CAP), and balance ability were measured using the berg balance scale (BBS) and functional reach test (FRT) before and after 8 weeks of intervention. Results: The experimental group showed statistically significant increases in posterior foot pressure and reductions in CAP after intervention. BBS and FRT scores also significantly improved. Although the control group showed some improvements, the changes were smaller and less consistent. Conclusion: Microcurrent stimulation targeting the gastrocnemius muscle improved plantar pressure symmetry and postural stability in stroke patients, suggesting its effectiveness as an adjunctive balance rehabilitation intervention.
