circuitry, AI-based motor control strategies, and musculoskeletal dynamics to simulate movement and neurological conditions affecting motor control. ReflexSim is intended for clinical and experimental motor control studies, enabling users to simulate standard tasks, adjust neurological parameters, and compare simulated outputs to patient or subject data. The platform also supports human-machine interface and robotics applications by integrating simulations into machine control systems to anticipate user movement. In sport and exercise contexts, it is used to estimate muscle activity beyond the reach of surface EMG, study compensation strategies after injury, and customize muscle models and recruitment patterns for specific physiques.
