摘要

研究设计可行性研究。目的确定进行一项大型试验的可行性，该试验旨在确定是否可以使用 ROBERT® 增强脊髓损伤（SCI）后髋屈肌的力量。ROBERT®是一种机器人装置，可在支撑腿部重量的同时提供辅助主动运动。重点是干预和结果测量的招募能力、适用性和可接受性。方法对所有首次入院的患者进行筛选，以评估参与者的招募能力。四名患有 SCI < 3 个月的患者接受了一项方案测试，该方案包括在 ROBERT® 的辅助下进行 60 次仰卧屈髋，每周三次，持续 4 周。根据方案的依从性和完成率，并从参与者的角度对可行性进行了评估。结果招募率为 8%（7 个月）。四名参与者完成了 48 个疗程中的 44 个疗程（92%）。无不良事件发生。每次训练都需要一名物理治疗师进行设置和监督。主动锻炼时间从 7.5 分钟到 17 分钟不等。参与者认为 ROBERT® 是对其常规康复训练的良好补充。我们甚至可以使用固定在框架上的测力计 MicroFET2 来测量非常薄弱的髋屈肌的 MVC。参与者认为它是一种补充，而不是常规物理治疗的替代品。然而，该研究的招募工作进展缓慢。试验注册ClinicalTrials.gov NCT05558254。注册日期：2022 年 9 月 28 日。

Robotic technology (ROBERT®) to enhance muscle strength in the hip flexor muscles following spinal cord injury: a feasibility study

Study design

Feasibility study.

Objective

To determine the feasibility of conducting a large trial designed to determine whether the ROBERT^® can be used to increase the strength of the hip flexor muscles after spinal cord injury (SCI). The ROBERT^® is a robotic device that provides assisted active movement while supporting the weight of the leg. Focus was on recruitment capability, suitability, and acceptability of the intervention and outcome measure.

Setting

Specialised SCI centre in Denmark.

Methods

All first-time admitted patients were screened to assess participant recruitment capability. Four people with SCI < 3 months tested a protocol consisting of 60 repetitions of hip flexion in supine conducted with the assistance of the ROBERT^® three times a week for 4 weeks. Feasibility was assessed based on adherence to the protocol and completion rate and from the participants’ perspectives. Maximal voluntary contraction (MVC) was accessed at baseline and four weeks.

Results

The recruitment rate was 8% (7 months). The four participants completed 44 out of 48 sessions (92%). No adverse events occurred. One physiotherapist was required to set-up and supervise each session. The active exercise time varied from 7.5 to 17 min. The participants found the ROBERT^® a good supplement to their usual rehabilitation. We were able to measure MVC in even very weak hip flexor muscles with a dynamometer MicroFET2 fixed to a frame.

Conclusion

The ROBERT^® was feasible and acceptable. The participants perceived it as a supplement, not a replacement to usual physiotherapy. However, recruitment to the study was slow.
