E-Mail:<\/strong> jagukpatel57@gmail.com<\/p>\n ABSTRACT<\/strong><\/p>\n Background:<\/strong>\u00a0Calf muscle spasticity is a common consequence after stroke and can impede the functional activation of antagonist muscles such as the tibialis anterior, affecting gait and mobility.<\/p>\n Objective:<\/strong>\u00a0To determine the relationship between calf muscle spasticity severity (via Modified Ashworth Scale, MAS) and tibialis anterior activation (via RMS, surface EMG) in chronic stroke patients.<\/p>\n Methods:<\/strong>\u00a0Cross-sectional study on 108 chronic stroke patients aged 35\u201365 years. Variables included Age, Gender, Side, MAS for calf, and tibialis anterior RMS. Spearman correlation and Kruskal-Wallis group analysis were applied.<\/p>\n Results:<\/strong>\u00a0There was a significant negative correlation between MAS and RMS (\u03c1 = \u20130.42, p < 0.001). RMS of tibialis anterior decreased with increasing calf muscle spasticity.<\/p>\n Conclusion:<\/strong>\u00a0Greater calf muscle spasticity is associated with reduced tibialis anterior activation, with important implications for gait rehabilitation and physiotherapy planning.<\/p>\n Keywords:<\/strong> Stroke, Spasticity, Tibialis Anterior, Surface Electromyography, Modified Ashworth Scale, Foot Drop, Chronic Stroke.<\/p>\n \u00a0REFERENCES<\/strong><\/p>\n [1].
