Abstract
Stair descent is one of the most biomechanically demanding and unstable gait patterns encountered in daily life. Despite this, comprehensive data integrating multiple physiological markers for this task remains scarce. This study will utilize high density surface electromyography (sEMG) and force plate technology. This study quantifies stair ambulation in healthy adults during stair ambulation. The specific aim is to establish a quantitative baseline for the firing intensity and timing of key lower limb muscles, specifically the gastrocnemius, soleus, and tibialis anterior, while navigating a six step staircase at a natural pace. Through the synchronization of muscle activation signals and joint kinematics. This study aims to identify the precise synergies that are required for stable descent. Defining these “healthy standards” for gait serves is a vital diagnostic benchmark for clinical populations. While healthy individuals navigate stairs with precision, certain clinical groups frequently exhibit compensatory patterns that increase fall risk and reduce mobility. This normative framework serves as a vital diagnostic benchmark for clinical populations, which enables the development of objective, data-driven rehabilitation protocols that target dysfunctional recruitment patterns in groups with elevated fall risk and reduced mobility.
