膝关节骨关节炎是导致成人行走障碍的主要原因。最常用的助行器，拐杖，通常负荷不足，因此不能减少膝关节负荷，并提供症状缓解。在这项研究中，一种新型的步行手杖与触觉生物反馈的设计，以改善手杖的负载和减少膝关节内收力矩（KAM）。确定; 1）使用触觉生物反馈以鼓励适当手杖负载的新型步行手杖的短期功效和2）新型手杖对KAM的影响。在五种条件下计算步行时的手杖载荷和KAM、峰值膝关节内收力矩（PKAM）和膝关节内收角冲量（KAAI）：1）初始，2A）量表训练后（站立时，使用平衡杆量表，对手杖施加20%BW），2B）量表回忆（尝试将手杖加载至20%BW），3A）触觉训练后（当达到目标手杖负载时传递振动触觉生物反馈）和3B）触觉回忆（尝试在传递振动触觉生物反馈的情况下将手杖负载到20%BW）。与初始条件相比，所有干预措施均显着增加甘蔗负荷并降低PKAM和KAAI。触觉回忆和量表回忆条件之间没有差异。触觉生物反馈手杖被证明是一种有效和简单的方法，以增加手杖负荷和减少膝关节负荷。触觉生物反馈和规模训练同样有效地产生立即短期改善手杖负荷和膝关节负荷。未来的研究应该检查尺度训练和触觉生物反馈手杖对膝关节健康，疼痛和骨关节炎疾病进展的长期影响。
Knee osteoarthritis is a leading cause of ambulatory disability in adults. The most prescribed mobility aid, the walking cane, is often underloaded and therefore fails to reduce knee joint loading and provide symptomatic relief. For this study, a novel walking cane with haptic biofeedback was designed to improve cane loading and reduce the knee adduction moment (KAM). To determine; 1) the short-term efficacy of a novel walking cane using haptic biofeedback to encourage proper cane loading and 2) the effects of the novel cane on KAM. Cane loading and KAM, peak knee adduction moment (PKAM), and knee adduction angular impulse (KAAI)) while walking were calculated under five conditions: 1) naïve, 2A) after scale training (apply 20%BW to cane while standing, using a beam scale), 2B) scale recall (attempt to load the cane to 20%BW), 3A) after haptic training (vibrotactile biofeedback delivered when target cane load achieved), and 3B) haptic recall (attempt to load the cane to 20%BW with vibrotactile biofeedback delivered). Compared to the naïve condition all interventions significantly increased cane loading and reduced PKAM and KAAI. No differences between haptic recall and scale recall condition were observed. The haptic biofeedback cane was shown to be an effective and simple way to increase cane loading and reduced knee loading. Haptic biofeedback and scale training were equally effective at producing immediate short-term improvements in cane loading and knee loading. Future studies should examine the long-term effects of scale training and canes with haptic biofeedback on knee joint health, pain, and osteoarthritis disease progression.
