Abstract
Lower‑limb exoskeletons are often used to study gait symmetry, but most existing work still focuses on assistive control strategies. Much less is known about how controlled resistance influences gait, even though resisting motion places different demands on the neuromuscular system and may lead to adaptations that assistance does not produce. The present study investigates how a unilateral ankle exoskeleton applying controlled resistance affects gait symmetry during self‑paced, level‑ground walking. The device used is the open‑source OpenExo platform, which allows ankle torque to be adjusted across several resistance levels. A single healthy adult completed walking trials under two conditions: a baseline condition and multiple resistance trials applied to the same side. Stance time was used to evaluate symmetry across conditions. This study is intended to get a better sense of how individuals react when resistance is applied to only one ankle, and whether that uneven loading shifts their gait patterns. The results may offer some insight into how resistance‑focused exoskeleton strategies could be used in rehabilitation to support gait training and motor adaptation.
