Spotter strap for the prevention of wheelchair tipping

Injuries caused by wheelchair rear-tipping accidents are common. This article reports on the safety and effectiveness of a spotter strap that attaches to the cross-brace or frame below the center of gravity of an occupied wheelchair. We videotaped five therapists spotting 89 wheelchair users while the users each performed six tasks that were designed to induce rear instability. We induced 16 episodes of complete rear tipping. In all cases, the spotter strap allowed the spotter to stay out of the way during the task, but step in easily when necessary to prevent the wheelchair user from being injured. In one instance, the spotter needed assistance lifting a heavy subject to the upright position after catching the subject with the strap. In summary, the spotter strap is a safe and effective device. We recommend its use when there is a high risk of a rear-tipping accident.
