We aimed to compare the efficacies of rehabilitation with the hybrid assistive limb and conventional rehabilitation after total knee arthroplasty.
A total of 37 consecutive patients who underwent primary total knee arthroplasty for knee osteoarthritis were enrolled. Seven patients withdrew from the study after randomization, and 30 patients (hybrid assistive limb group: n = 16; conventional group: n = 14) completed the randomized controlled trial. Patients in the hybrid assistive limb group underwent ten 20-min rehabilitation sessions with the hybrid assistive limb as well as 20-min conventional sessions over the course of 2 weeks, whereas patients in the conventional group received ten 40-min conventional sessions during the same period. The primary outcome measure was walking speed, whereas the secondary outcome measures included quadriceps strength and knee pain assessed using a numerical rating scale. The outcome measures were evaluated prior to surgery and on postoperative weeks 1, 2, and 3.
In the early postoperative period, rehabilitation after total knee arthroplasty with the hybrid assistive limb resulted in a significantly greater improvement in walking speed (weeks 1 and 2: p = 0.045), quadriceps strength (weeks 1 and 2; weeks 1 and 3: p < 0.0001), and numerical rating scale scores (week 1: p = 0.03) than conventional rehabilitation.
Rehabilitation with the hybrid assistive limb after total knee arthroplasty led to greater improvements in walking speed, quadriceps strength, and pain scores than conventional rehabilitation.
我们旨在比较全膝关节置换术后使用混合辅助肢体康复与传统康复的疗效。
连续纳入37例因膝关节骨关节炎接受初次全膝关节置换术的患者。7例患者在随机分组后退出研究，30例患者（混合辅助肢体组：n = 16；传统组：n = 14）完成了随机对照试验。混合辅助肢体组的患者在2周内接受了10次每次20分钟的混合辅助肢体康复训练以及20分钟的传统康复训练，而传统组的患者在同一时期接受了10次每次40分钟的传统康复训练。主要结局指标为步行速度，次要结局指标包括股四头肌力量和使用数字评分量表评估的膝关节疼痛。在手术前以及术后第1、2和3周对结局指标进行评估。
在术后早期，全膝关节置换术后使用混合辅助肢体进行康复训练，在步行速度（第1周和第2周：p = 0.045）、股四头肌力量（第1周和第2周；第1周和第3周：p < 0.0001）以及数字评分量表评分（第1周：p = 0.03）方面的改善均显著大于传统康复训练。
全膝关节置换术后使用混合辅助肢体进行康复训练在步行速度、股四头肌力量和疼痛评分方面比传统康复训练有更大的改善。
