The objective of this study was to investigate the effects of providing a motorized scooter on physical performance and mobility. Participants were ambulatory, community-dwelling outpatients with rheumatoid arthritis or osteoarthritis of the knee. Results showed that the majority of scooter subjects (n=16/22 [72.7%]) used the scooter 4 or more days per week. The difference ± standard deviation between the 2 groups in change in 6MWD over the study period was not statistically significant (scooter users, 16.9±73.0m [55.5±239.6ft]; usual care, 17.2±72.5m [56.5±238.0ft], P=.55). Four (18.1%) scooter users reported 9 accidents. Over the study period, the proportion of persons reporting use of a scooter (provided by the study or otherwise available) increased in the scooter-users group (eg, food stores, 16.7% to 52.6%; doctor’s office, 0% to 35.7%) but not the usual-care group (food stores, 9.1% to 9.5%; doctor’s office, 0% to 0%). The study concludes that motorized scooters provided to ambulatory persons with arthritis were used intermittently. The greatest short-term risk from scooter usage appeared to be minor collisions.
