Evaluation of scooters using ANSI/RESNA standards

This research evaluates and compares the performance of various scooter models based on American National Standards Institute/Rehabilitation Engineering and Assistive Technology Society of North America (ANSI/RESNA) tests. Results show varying responses in stability, environmental conditions, power systems, and more, highlighting inconsistencies in current scooter models and suggesting potential risks to users. The study provides quantitative data to inform the development of future scooters and aid clinicians and users in selecting suitable devices.

  2. Aim • Evaluate and compare scooter model performance on American National Standards Institute/ Rehabilitation Engineering and Assistive Technology Society of North America (ANSI/RESNA) tests. • Relevance • Absence of objective test reports and evidence of high rate of wheelchair breakdowns in community have led to speculation that not all commercially available devices meet ANSI/RESNA standards.

  3. Method • Tested 12 three-wheeled scooters according to ANSI/RESNA wheelchair standards. • Scooter models • Victory, Gogo, Golden Companion (GC) I, and GC II. • Tests • Static stability; dynamic stability; effectiveness of brakes; energy consumption; maximum speed, acceleration, and deceleration; climatic; static, impact, and fatigue; power and control systems; tiller.

  4. Results • Stability • Most: Victory and GC II. • Least: Gogo. • Environmental conditions • 3 Gogo, 1 GC I, 1 GC II failed. • Power and control systems • All GC I and II scooters failed parts of. • Static and impact • All scooters passed. • However, all Gogo scooters and one GC II scooter had structural or motor failure during durability tests. • Survival life • 62,512 to 1,178,230 cycles out of 400,000 needed to pass. • Tiller failures • Occurred with average 1,483 N applied force.

  5. Conclusion • Results showed inconsistent responses from scooter models within each standard test. • Suggests current models on market: • Are not as reliable as they should be. • May be putting users at risk of injuries. • Results provided quantitative data that will: • Benefit quality of future scooters developed. • Help clinicians and users identify appropriate device for specific user.
