Abstract

Background

The most effective exercise variables for rotator cuff tendinopathy are unknown.

Objective

Determine feasibility of a fully powered trial comparing high load-volume versus low load-volume exercise for adults with rotator cuff tendinopathy.

Design

Two arm, multi-centre pilot and feasibility randomised controlled trial.

Methods

Participants aged over 18 were recruited via social media and randomised into 12 weeks of either high load-volume exercise (i.e. with dumbbell resistance) or low load-volume exercise (i.e. without added resistance). Feasibility outcomes were rates of recruitment, retention, questionnaire completion, adverse events and adherence to prescribed exercise.

Results

Fifteen participants were randomised to high load-volume and 16 to low load-volume (18/31 were female). Retention rate was 84% at 6 weeks, and 81% at 12 and 26 weeks. Five participants withdrew and one participant was lost to follow up. Questionnaire completion rate was 78%. Adherence to the prescribed exercise sets was 77%. Recruitment, conversion and retention rates were above the pre-defined success criterion. There were no serious adverse events.

Conclusion

A fully powered multi-centre randomised trial is feasible with minor amendments addressing exercise adherence and questionnaire response rate. Future trials should utilise outcomes that consider participants baseline physical activity levels and adequately measure pain disparate from performance.

大负荷量运动与小负荷量运动对肩袖肌腱病的疗效对比：试点和可行性试验

背景对肩袖肌腱病最有效的运动变量尚不清楚.目的确定一项完全有效的试验的可行性，比较成人肩袖肌腱病患者的高负荷运动量和低负荷运动量.设计双臂、多中心试点和可行性随机对照试验.方法通过社交媒体招募 18 岁以上的参与者，并随机分配其参加为期 12 周的高负荷运动量（即有哑铃阻力）或低负荷运动量（即无附加阻力）.结果15 名参与者被随机分配到高负荷运动量，16 名参与者被随机分配到低负荷运动量（即无附加阻力）.结果15 名参与者被随机分配到高负荷运动量，16 名参与者被随机分配到低负荷运动量（即无附加阻力）.结果15 名参与者被随机分配到高负荷运动量，16 名参与者被随机分配到低负荷运动量（即无附加阻力）.可行性结果包括招募率、保留率、问卷完成率、不良事件发生率以及对规定运动的坚持率。结果15名参与者被随机分配到高负荷运动量运动中，16名参与者被随机分配到低负荷运动量运动中（18/31为女性）。6周的保留率为84%，12周和26周的保留率为81%。五名参与者退出，一名参与者失去随访机会。问卷完成率为 78%。对规定运动组的坚持率为 77%。招募率、转换率和保留率均高于预先设定的成功标准。结论：针对运动依从性和问卷回复率稍作修改后，一项完全有效的多中心随机试验是可行的。未来的试验应利用考虑参与者基线体力活动水平的结果，并充分测量与表现不同的疼痛。
