Multifaceted evaluation of the Angel X passive back-support exoskeleton (3 kg, 14-16 Nm adjustable torque): 15 males performed repetitive 10 and 15 kg lifting and static holding while 12-channel EMG, full-body kinematics, indirect-calorimetry metabolic cost and subjective exertion/discomfort were measured (Scientific Reports, 2025).
