Fatigue-progression study of the H-PULSE semi-active shoulder-support exoskeleton with motor-adjustable spring preload: 10 participants performed 6 minutes of continuous overhead screwing at different support levels and without the device, while bilateral deltoid EMG (median- frequency fatigue analysis), heart rate and HRV were recorded (Wearable Technologies, 2025). Data available by email to the corresponding author.
