Objectives
To quantify mobility scooter performance when traversing snow, ice, and concrete in cold temperatures and to explore possible performance improvements with scooter winter tires. Design Cross-sectional. Setting Hospital-based research institute. Participants Two drivers (50 and 100 kg) tested 8 scooter models (N=8). Two mobility scooters were used for winter tire testing. Interventions Scooters were tested on 3 different conditions in a random sequence (concrete, 2.5-cm depth snow, bare ice). Ramp ascent and descent, as well as right-angle cornering up to a maximum of 10° slopes on winter conditions, were observed. Winter tire testing used the same slopes with 2 scooters on bare and melting ice surfaces. Main Outcome Measures Maximum achievable angle (MAA) and tire traction loss for ramp ascent and descent performance. The ability to steer around a corner on the ramp. Results All scooters underperformed in winter conditions, specifically when traversing snow- and ice-covered slopes (χ2 [2, N=8]=13.87-15.55, P<.001 and corners n="8]=12.25," p half of the scooters we tested were unable to climb a grade snow-covered slope without losing traction. all but failed ascend an ice-covered slope. performance was even more unsatisfactory for forward downslopes on both snow ice. winter tires enhanced maa permitting ascent> Conclusions Mobility scooters need to be designed with winter months in mind. Our findings showed that Americans with Disabilities Actcompliant built environments, such as curb ramps that conform to a 1:12 (4.8°) slope, become treacherous or impassible to mobility scooter users when covered in ice or snow. Scooter manufacturers should consider providing winter tires as optional accessories in regions that experience ice and snow accumulation. Additional testing/standards need to be established to evaluate winter mobility scooter performance further. |
