Evaluation of scooters using ANSI/RESNA standards

Area of Science:

• Rehabilitation Engineering
• Assistive Technology
• Medical Device Safety

Background:

• Limited research exists on scooter stability and performance under adverse conditions.
• Previous studies have not comprehensively evaluated scooters against established standards.

Purpose of the Study:

• To assess the stability, durability, and safety of three-wheeled scooters against ANSI/RESNA standards.
• To identify specific failure points and areas for improvement in scooter design and testing.

Main Methods:

• Twelve three-wheeled scooters (Victory, Gogo, Golden Companion I & II) were tested using ANSI/RESNA wheelchair standards.
• Tests included static and dynamic stability, environmental conditions, power/control systems, and durability.

Main Results:

• Victory and GC II scooters demonstrated the highest stability; Gogo scooters were least dynamically stable.
• Five scooters failed environmental tests; GC I & II models failed power/control tests.
• All Gogo scooters and one GC II failed durability tests; tiller failures were frequent.

Conclusions:

• Commercially available scooters may not meet current ANSI/RESNA safety and durability standards.
• Tiller testing with appropriate weight-capacity dummies is recommended for enhanced safety evaluation.
• Further research and standardized testing are crucial for mobility device safety.
