Reduces caregiver low‑back strain during repetitive patient handling tasks (bed mobility, toileting, transfers), which are known risk activities for lumbar overload; passive back exoskeletons have been shown to cut back extensor muscle activity by roughly 24–34% in lifting tests, supporting injury prevention for staff in eldercare environments. Encourages ergonomic compliance in tight spaces and high‑frequency tasks by providing assistance precisely during trunk flexion/extension, which can reduce cumulative loading at L5/S1 and perceived exertion across an 8‑hour shift, improving staff stamina and patient handling safety.
