This paper describes the design of a system for the dynamic assessment of the upper limb in participants with neuromuscular disorders. The system is based on a circular structure for controlled movements with seven radial tracks and LED visual guidance, allowing the standardization of trajectories and movement speeds. The instrumentation integrates simultaneous recordings of EEG (64 channels), high-density surface electromyography (320 HD-sEMG channels), and infrared markers to track the upper limb position during movement. Synchronization between devices (LEDs, amplifier and motion tracking cameras) is managed via auxiliary signals controlled by an Arduino microcontroller. An ergonomic handle designed to compensate for spastic wrist conditions is included. The goal is to extract objective biomarkers, such as activation maps and cortico-muscular coherence, to quantify neuromuscular recovery and the interaction between central and peripheral components of voluntary motor activation.
