The objective of this study was to determine the feasibility and effectiveness of using SUpported Motivational InTerviewing (SUMIT) to increase physical activity in people with knee osteoarthritis (KOA).
Randomised controlled trial.
We recruited people who had completed Good Life with osteoArthritis Denmark (GLA:D) from private, public and community settings in Victoria, Australia.
Participants were randomised participants to receive SUMIT or usual care. SUMIT comprised five motivational interviewing sessions targeting physical activity over 10 weeks, and access to a multimedia web-based platform.
Thirty-two participants were recruited (17 SUMIT, 15 control) including 22 females (69%).
Feasibility outcomes included recruitment rate, adherence to motivational interviewing, ActivPAL wear and drop-out rate. Effect sizes (ESs) were calculated for daily steps, stepping time, time with cadence >100 steps per minute, time in bouts >1 min; 6 min walk distance, Knee Osteoarthritis Outcome Score (KOOS) subscales (pain, symptoms, function, sport and recreation, and quality of life (QoL)), Euroqual, systolic blood pressure, body mass index, waist circumference, 30 s chair stand test and walking speed during 40 m walk test.
All feasibility criteria were achieved, with 32/63 eligible participants recruited over seven months; with all participants adhering to all motivational interviewing calls and achieving sufficient ActivPAL wear time, and only two drop-outs (6%).12/15 outcome measures showed at least a small effect (ES>0.2) favouring the SUMIT group, including daily time with cadence >100 steps per minute (ES=0.43). Two outcomes, walking speed (ES= 0.97) and KOOS QoL (ES=0.81), showed a large effect (ES>0.8).
SUMIT is feasible in people with knee osteoarthritis. Potential benefits included more time spent walking at moderate intensity, faster walking speeds and better QoL.

本研究旨在确定使用支持性动机访谈（SUMIT）来增加膝骨关节炎（KOA）患者身体活动的可行性和有效性。
随机对照试验。
我们从澳大利亚维多利亚州的私人、公共和社区环境中招募了完成丹麦骨关节炎生活质量（GLA:D）的人群。
参与者被随机分配接受 SUMIT 或常规护理。SUMIT 包括五个针对身体活动的动机访谈，持续 10 周，并可访问多媒体网络平台。
共招募了 32 名参与者（17 名 SUMIT，15 名对照组），包括 22 名女性（69%）。
可行性结果包括招募率、对动机访谈的依从性、ActivPAL 佩戴和脱落率。计算了每日步数、踏步时间、步频>100 步/分钟的时间、持续时间>1 分钟的时间；6 分钟步行距离、膝关节骨关节炎结局评分（KOOS）亚量表（疼痛、症状、功能、运动和娱乐以及生活质量（QoL））、Euroqual、收缩压、体重指数、腰围、30 秒坐站测试和 40 米行走测试中的行走速度。
SUMIT 在膝骨关节炎患者中是可行的。潜在的益处包括更多的时间以适度的强度行走，更快的行走速度和更好的生活质量。
