Before beginning a large and complex trial it is considered good practice to run a pilot study to assess the feasibility and acceptability so that quality is maintained and resources are not wasted.
To assesses the feasibility and acceptability of procedures for TOPS: Trial Of Prevention Strategies for low back pain.
Randomised controlled pilot trial.
This is a trial of an 8 week, physiotherapist-led group exercise and education program for preventing recurrence of low back pain (LBP) in those recently recovered from LBP. We assessed the feasibility of recruitment and data-collection procedures, acceptability of the trial interventions and loss-to-follow up.
The feasibility of recruitment, acceptability of the intervention and feasibility of physical activity data-collection procedures were all below anticipated levels. We enrolled 12 participants over 44 weeks, the adherence rate for the intervention group was 63% and valid physical activity data were obtained for 67% of the measurements. Follow-up methods for collection of LBP recurrence were successful with this information able to be collected for 100% of participants.
In response to the pilot, modifications were made to the main trial protocol. We will increase recruitment by relaxing inclusion criteria and expanding recruitment sites to include workplaces, community centres and via social media. We will facilitate compliance by expanding treatment sites to provide more options for participants to access the program and we will limit missing data by checking the validity of baseline physical activity measures prior to enrolment.
The study was prospectively registered with the Australian and New Zealand Clinical Trials Registry (ref: ACTRN12614000706673).
在开展大型复杂试验之前,进行试点研究以评估其可行性和可接受性被认为是良好的做法,这样可以确保质量并避免资源浪费。
评估 TOPS(预防腰痛策略试验)的程序的可行性和可接受性。
随机对照试点试验。
这是一项针对近期腰痛(LBP)康复患者的为期 8 周、由物理治疗师主导的团体运动和教育计划,旨在预防腰痛复发。我们评估了招募和数据收集程序的可行性、试验干预措施的可接受性以及失访情况。
招募的可行性、干预措施的可接受性以及体力活动数据收集程序的可行性均低于预期水平。我们在 44 周内招募了 12 名参与者,干预组的依从率为 63%,并且有 67%的测量数据获得了有效的体力活动数据。通过收集 LBP 复发的随访方法成功收集了 100%参与者的信息。
根据试点研究的结果,对主要试验方案进行了修改。我们将放宽纳入标准并扩大招募地点,包括工作场所、社区中心和社交媒体,以增加招募人数。我们将扩大治疗地点,为参与者提供更多获取该计划的选择,以提高依从性,同时在入组前检查基线体力活动测量的有效性,以减少数据缺失。
该研究在澳大利亚和新西兰临床试验注册中心(注册号:ACTRN12614000706673)进行了前瞻性注册。
