Trunk range of motion in the sagittal plane with and without a flexible back support exoskeleton

A large portion of the working population is affected by back and shoulder pain. Lower back support exoskeletons were introduced as a preventative measure, but they are not widely adopted by the industry yet. Their adoption is hindered chiefly by discomfort, loss of range of motion and kinematic incompatibility. In this work, we discuss the range of motion of the trunk in the sagittal plane, once wearing a flexible exoskeleton and once without wearing an exoskeleton (N = 2).
