To investigate the effects of providing a motorized scooter on physical performance and mobility.
Randomized clinical trial comparing scooter users with usual care.
One academic and 1 Veterans Affairs medical center.
Ambulatory, community-dwelling outpatients with rheumatoid arthritis or osteoarthritis of the knee.
Provision of a motorized scooter for 3 months.
Six-minute walk distance (6MWD) and mobility methods in diverse locations at baseline, 1 month, and 3 months, and accidents while using the scooter.
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+/-73.0 m [55.5+/-239.6 ft]; usual care, 17.2+/-72.5 m [56.5+/-238.0 ft], 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%).
Motorized scooters provided to ambulatory persons with arthritis were used intermittently. The greatest short-term risk from scooter usage appeared to be minor collisions.
研究提供电动踏板车对身体机能和活动能力的影响。
将踏板车使用者与常规护理进行比较的随机临床试验。
一家学术医疗中心和一家退伍军人事务医疗中心。
患有膝关节类风湿性关节炎或骨关节炎的非卧床社区门诊患者。
提供电动踏板车，为期3个月。
在基线、1个月和3个月时，在不同地点的6分钟步行距离（6MWD）和活动能力方法，以及使用踏板车时发生的事故。
大多数踏板车使用者（n = 16/22 [72.7%]）每周使用踏板车4天或更多天。在研究期间，两组在6MWD变化方面的差异±标准差无统计学意义（踏板车使用者，16.9±73.0米[55.5±239.6英尺]；常规护理组，17.2±72.5米[56.5±238.0英尺]，P = 0.55）。四名（18.1%）踏板车使用者报告了9起事故。在研究期间，踏板车使用者组中报告使用踏板车（由研究提供或其他途径获得）的人数比例有所增加（例如，食品店，从16.7%增至52.6%；医生办公室，从0%增至35.7%），而常规护理组则没有变化（食品店，从9.1%增至9.5%；医生办公室，从0%增至0%）。
提供给非卧床关节炎患者的电动踏板车使用具有间歇性。使用踏板车的最大短期风险似乎是轻微碰撞。
