遗传性感觉和自主神经病变（HSAN）包括涉及各种感觉和自主神经功能障碍的遗传性疾病。HSAN 4型和5型（HSAN-4和-5）的特征在于先天性对疼痛和热感觉不敏感。HSAN-4和-5中的骨科问题包括破坏性损伤。步态研究表明，与对照组相比，患者的速度更快，脚跟接触角速度更高。这种“砰砰的步态”可能是对疼痛不敏感的结果，也可能是他们受伤的原因。为了防止受伤，我们正在探索使用我们的新型听觉反馈设备（听觉足），将足部接触压力转化为声音。在本文中，我们报告了一个先天性疼痛不敏感的参与者的听觉反馈的直接有益效果。参与者是一名患有HSAN-4的12岁女孩。我们在她的双脚上安装了听觉足部设备，并在她在跑步机上行走时测量了她的足部压力。当听觉反馈被打开时，参与者步态中的双脚峰值压力下降。先天性对疼痛不敏感的患者倾向于以“砰砰”的方式行走;增加他们对足部接触的意识可能会改善他们的步态。
Hereditary sensory and autonomic neuropathy (HSAN) includes genetic disorders that involve various sensory and autonomic dysfunctions. HSAN types 4 and 5 (HSAN-4 and -5) are characterized by congenital insensitivity to pain and thermal sensation. Orthopedic problems in HSAN-4 and -5 include destructive injuries. Studies on gait have shown greater speed and higher heel contact angular velocity in the patients compared to controls. Such a “banging gait” may be the result of insensitivity to pain, and may be a cause of their injuries. To help prevent injuries, we are exploring the use of our novel auditory feedback device (Auditory Foot) that converts foot contact pressure into sound. In this paper, we report an immediate beneficial effect of auditory feedback in a participant with congenital insensitivity to pain. The participant was a 12-year-old girl with HSAN-4. We mounted the Auditory Foot device on both her feet and measured her foot pressure during gait as she walked on a treadmill. The peak pressure during the participant's gait decreased in both feet when auditory feedback was switched on. Patients with congenital insensitivity to pain tend to walk in a “banging” way; increasing their awareness of their foot contact may improve their gait.
