Validation data for an NUS passive shoulder exoskeleton that relocates its 3.2 kg mass to the wearer's back via Bowden cables (0.2 kg per arm) and matches the shoulder's nonlinear torque demand with a spring-cam mechanism: 10 males performed overhead drilling and sustained-flexion tasks with and without the device (Wearable Technologies, 2023). EMG data available by email to the corresponding author.
