This study discusses the development of a low-speed, low-impact test dummy for use in the study of fall prevention from wheelchairs.

Investigators evaluated whether a modified 50th-percentile Hybrid III test dummy (HTD) has motion similar to a wheelchair test pilot (TP) with waist-level spinal cord injury.

Test cases were seated in a Quickie P100 electrically powered wheelchair driven at three speeds. Three braking conditions-joystick release, joystick full reverse, and emergency power-off-were used to stop the wheelchair.

Upper-body motion was recorded to create kinematic exposure profiles of the wheelchair riders. Data indicate that the HTD is a suitable surrogate for a wheelchair user in low-speed, low-impact wheelchair studies.
