Summary

This cross-sectional, comparative study aims to evaluate and compare the surface electromyographic (sEMG) activity of the gastrocnemius (medial and lateral) and soleus muscles during static and dynamic contraction tasks. Participants will perform three tests-resting state, isometric, concentric, and eccentric contraction, and dynamic gait-with bilateral measurements. A subgroup analysis will examine muscle activity variations based on foot posture, using the Foot Posture Index (FPI). The study uses the validated mDurance® sEMG system to obtain objective data under controlled lab conditions. The findings will enhance understanding of the functional role of each muscle and could inform rehabilitation and injury prevention strategies.

Muscle contraction protocol for electromyographic assessment

Participants will perform a set of standardized lower limb muscle contractions (isometric, concentric, and eccentric) involving the gastrocnemius and soleus muscles while lying on an examination table and in standing position both static and dynamic as well as walking. Surface electromyography (mDurance® sEMG system) will be used to record muscle activation during each phase. The task is designed for physiological measurement only and does not constitute a therapeutic intervention. Protocol includes 3 trials per muscle and side, using standardized test conditions.
