Abstract
Introduction: Partial Weight Bearing (PWB) is integral to rehabilitation protocols following orthopedic and trauma surgeries. Standard of Care (SOC) for PWB training often involves using a bathroom scale, a method criticized for its inaccuracy. This study aimed to compare SOC training in PWB with a biofeedback device (insole).
Methods: Sixty healthy participants were randomized into SOC or Biofeedback (BF) training groups, practicing 20 kg PWB using a standardized protocol. Gait data, including compliance with weightbearing restrictions (not exceeding 150% of the set weightbearing limit), was monitored using Loadsol® insole force sensors. Participant satisfaction and usability were assessed through questionnaires. Training duration and walking speed were also measured.
Results: The BF group's peak force averaged 330 Newtons, significantly lower than the SOC group's 600 Newtons, which exceeded the prescribed limit by over three times (p ≤ 0.001). Compliance with weightbearing restrictions was substantially higher in the BF group (88% or 29/33 participants) compared to the SOC group (19% or 5/27 participants) (p ≤ 0.001). The BF group also required less training time to learn PWB, averaging 9:00 ± 3:06 minutes, versus 12:49 ± 3:01 minutes in the SOC group (p ≤ 0.001). Questionnaire responses showed no significant differences between groups.
Conclusion: Real-time audio-visual Biofeedback significantly enhances compliance with weightbearing restrictions in PWB training while reducing the training duration. Based on these findings, the implementation of biofeedback devices in PWB training is recommended.
部分负重(PWB)是骨科和创伤手术后康复方案中不可或缺的一部分。PWB培训的护理标准(SOC)通常涉及使用浴室称,这种方法因其不准确而受到批评。本研究的目的是比较生物反馈装置(鞋垫)在PWB中的SOC训练。方法:60名健康受试者随机分为SOC组和BF组,采用标准化训练方案进行20 kg PWB训练。步态数据,包括遵守负重限制(不超过设定负重限制的150%),使用Loadsol®鞋垫力传感器进行监测。通过问卷调查评估参与者满意度和可用性。训练时间和步行速度也被测量。结果:BF组的峰值力平均为330牛顿,显著低于SOC组的600牛顿,超出规定限值3倍以上(p≤0.001)。与SOC组(19%或5/27)相比,BF组(88%或29/33)对负重限制的依从性要高得多(p≤0.001)。BF组学习PWB所需的训练时间也更少,平均为9:00±3:06分钟,而SOC组为12:49±3:01分钟(p≤0.001)。问卷调查结果显示各组间无显著差异。结论:实时视听生物反馈可显著提高PWB训练中负重限制的依从性,缩短训练时间。基于这些发现,建议在PWB培训中实施生物反馈装置。证据等级:3。
