BACKGROUND
Removable cast walkers (RCWs), with or without modifications, are used to offload diabetes-related foot ulcers (DRFUs), however there is limited data relating to their offloading effects. This study aimed to quantify plantar pressure reductions with an RCW with and without modification for DRFUs.
METHODS
This within-participant, repeated measures study included 16 participants with plantar neuropathic DRFUs. Walking peak plantar pressures at DRFU sites were measured for four conditions: post-operative boot (control condition), RCW alone, RCW with 20 mm of felt adhered to an orthosis, and RCW with 20 mm of felt adhered to the foot.
RESULTS
Compared to the control condition, the greatest amount of peak plantar pressure reduction occurred with the RCW with felt adhered to the foot (83.1% reduction, p < .001). The RCW with felt adhered to the foot also offered greater peak plantar pressure reduction than the RCW alone (51.3%, p = .021) and the RCW with felt adhered to an orthosis (31.4%, p = .009).
CONCLUSION
The largest offloading effect recorded was with the RCW with felt adhered to the foot. High-quality randomised trials are now needed to evaluate the effectiveness of this device for healing DRFUs.
背景
可移动的石膏助行靴（RCWs），无论是否经过改装，都用于减轻糖尿病相关足部溃疡（DRFUs）的压力，但关于其减压效果的数据有限。本研究旨在定量测量 DRFUs 患者使用 RCW 及其改装前后的足底压力降低情况。
方法
这是一项参与者内、重复测量的研究，共纳入 16 名患有足底神经病变性 DRFUs 的患者。在四种情况下测量 DRFU 部位的步行峰值足底压力：术后靴子（对照条件）、单独使用 RCW、RCW 上附有 20mm 厚毛毡的矫形器、RCW 上附有 20mm 厚毛毡的足部。
结果
与对照条件相比，RCW 上附有毛毡的足部可最大程度地降低峰值足底压力（减少 83.1%，p<0.001）。RCW 上附有毛毡的足部比单独使用 RCW（减少 51.3%，p=0.021）和 RCW 上附有毛毡的矫形器（减少 31.4%，p=0.009）提供更大的峰值足底压力降低。
结论
记录到的最大减压效果是 RCW 上附有毛毡的足部。现在需要进行高质量的随机试验来评估该设备对治疗 DRFUs 的有效性。
