Previous studies have shown limited therapy compliance in weight-bearing in patients following total hip arthroplasty.
The purpose of this pilot RCT is to determine the immediate and late effect of real-time, visual biofeedback on weight-bearing during rehabilitation after THA in elderly.
24 participants who underwent THA were randomized to either the control or the intervention group. The intervention group received real-time, visual biofeedback on weight-bearing during training with the physical therapist during hospitalization and at twelve weeks follow up.
Without biofeedback, therapy compliance was limited. Significant improvement in peak load was found in the intervention group in the early postoperative phase. In contrast to the control group, the peak load at twelve weeks was significantly higher in the intervention group compared to the pre-operative peak load, indicating a lasting effect of early biofeedback. Other gait parameters were not significantly different in the early postoperative phase. In the intervention group a longer walking distance was observed and the use of walking aids was reduced at twelve weeks.
Biofeedback systems could be promising to improve outcomes and reduce costs in future rehabilitation programs after THA.
先前的研究表明，全髋关节置换术后患者在承重时的治疗依从性有限。
本先导随机对照试验的目的是确定实时可视生物反馈对老年全髋关节置换术后康复期间承重的即时和晚期影响。
24 名接受全髋关节置换术的参与者被随机分配到对照组或干预组。干预组在住院期间和 12 周随访期间接受物理治疗师进行的实时可视生物反馈承重训练。
没有生物反馈，治疗依从性有限。干预组在术后早期的峰值负荷有显著改善。与对照组相比，干预组在 12 周时的峰值负荷明显高于术前峰值负荷，表明早期生物反馈有持久的效果。其他步态参数在术后早期阶段没有显著差异。在干预组中，观察到行走距离更长，12 周时使用助行器减少。
生物反馈系统有望改善全髋关节置换术后未来康复计划的结果并降低成本。
