Task analysis using Behavior-based safety (BBS) for making safety check list for physical therapist

Powered exoskeleton is beginning to be used to support independent gait in patients with spinal cord injury (SCI). So far, there have been some reports on methodology for walking assistance and usability of the exoskeletons, but the current situation is that measures for occupational safety for therapists themselves have hardly been examined. As the first step of the goal of building a safety checklist for caregivers, behavior of PT was observed and analyzed in the present study.
