<p dir="ltr"> A passive, sensorized 3-DoF arm served as the end-effector support. The dominant-arm forearm was secured to the end-effector via a rigid forearm support. Three bottle locations were defined on the workspace: one central position, one at -35 degrees (right of center), and one at +35 degrees (left of center), all at the same radial distance from the subject. Surface EMG (sEMG) was acquired at 2222~Hz using a Delsys wireless system equipped with Quattro and Avanti sensors and Ag/Cl electrodes. Twelve muscles were monitored: anterior (AD), middle (MD), and posterior deltoids (PD); pectoralis major (PM); infraspinatus (INF); teres major (TM); biceps brachii (short head, BS); triceps brachii (long head, TL); brachioradialis (BR); extensor digitorum (ED); flexor digitorum (FD); and abductor pollicis brevis (APB). A figure of Joint angles and the end-effector position of the 3-DoF passive arm were sampled at 100~Hz using RLS Orbis absolute encoders mounted at each joint.</p><p dir="ltr">Participants were seated on a chair positioned in front of the HandExo rehabilitation platform. After electrode placement, each participant performed maximum voluntary contraction (MVC) trials used for subsequent normalization of EMG amplitudes: these trials include flexion/extension of the shoulder, internal/external rotation of the shoulder, flexion/extension of the elbow, and open/close of fingers. Participants then donned the wrist splint and were guided to a standardized initial posture: the wrist center located 70~cm from the central bottle, with the elbow configured so that the central bottle could be reached at full elbow extension. For each of the three bottle locations, participants completed 7 reach-to-grasp-and-return trials, starting from the initial position, reaching to grasp the bottle, and returning to the initial position. In total, each participant performed 3 * 7 = 21 trials.</p><p dir="ltr"><br></p>
