下肢感觉丧失的个体经常经历姿势不稳定、步态模式改变和跌倒风险增加，最终导致生活质量下降。以前的研究已经证明，使用踝足矫形器（AFO）可以帮助这些人保持平衡。本研究旨在探讨躯体感觉线索是否传递到踝关节以上的下肢完整组织，提高周围神经病患者的姿势控制。该研究涉及12名因糖尿病而患有感觉神经病变的人，他们参加了静态和动态平衡测试，有和没有专门设计的AFO，为下肢提供辅助感觉提示，而不稳定踝关节。在测试过程中，受试者被要求交替地站在固定和移动的平台上，眼睛交替地睁开或闭合。获得平衡评分和反应时间。结果表明，与无AFO的条件相比，在实验中与特别修改的AFO的平衡分数显着更高。在AFO的条件下也记录了较小的潜伏期评分。结果表明，AFOs替代本体感觉反馈的缺乏可能会改善糖尿病周围神经病变患者的自动姿势反应。它还强调了需要进一步研究的重点是辅助手段的设计，可以改善个人的平衡和日常生活活动的表现与本体感受缺陷。
Individuals with a loss of sensation in the lower limbs frequently experience postural instability, altered gait patterns, and an increased risk of falling culminating in a decreased quality of life. Previous studies have documented that using ankle-foot orthoses (AFOs) help such individuals to maintain their balance. This study was conducted to investigate whether somatosensory cues delivered to the intact tissues of the lower limbs above the ankle joints enhance the control of posture in individuals with peripheral neuropathy. The study involved 12 individuals with sensory neuropathy because of diabetes who participated in static and dynamic balance tests with and without specially designed AFOs that provided auxiliary sensory cues to the lower limbs without stabilizing the ankle joints. During the tests, the subjects were required to alternately stand on a fixed and moving platform with their eyes alternately open or closed. Equilibrium scores and response latencies were obtained. The results showed that equilibrium scores were significantly higher in experiments with the specially modified AFOs compared with conditions without AFOs. Smaller latency scores were recorded in conditions with AFOs as well. The outcome indicates that AFOs that substitute for the lack of proprioceptive feedback may improve automatic postural responses in individuals with diabetic peripheral neuropathy. It also highlights the need for further research focused on the design of assistive means that could improve the balance and the performance of activities of daily living in individuals with proprioceptive deficits.
