The peroneal reaction time (PRT) is used in the assessment of neuromuscular deficits in chronic functional ankle instability. Powered by the Editorial Manager and Preprint Manager from Aries Systems Corporation the present study was conducted to determine the PRT in a large collective of patients with chronic ankle instability because it is unclear if this parameter of neuromuscular deficit is prolonged. In this study 186 patients underwent a diagnostic algorithm consisting of anamnesis, clinical examination, X-ray and determination of the PRT on a tilting platform. A prolonged PRT as a manifestation of a neuromuscular deficit could be detected in the majority of the patients (n = 143, 77%). Comparing the affected and healthy legs 77 patients (41%) showed a significant difference in talar shift (p = 0.002) and talar tilt (p = 0.04) in the radiological stress views. Of these 77 patients only 15 (8%) showed radiological evidence of a mechanical problem. As a consequence of recurring ankle sprains a post-traumatic deficit in proprioception has to be expected in most cases. In general a conservative therapy approach should be followed including specific training to improve neuromuscular and proprioceptive deficits.
腓骨反应时间（PRT）用于评估慢性功能性踝关节不稳患者的神经肌肉功能缺陷。本研究由Aries Systems Corporation的编辑管理器和预印本管理器提供支持，旨在确定大量慢性踝关节不稳患者的PRT，因为目前尚不清楚这种神经肌肉功能缺陷参数是否延长。在本研究中，186例患者接受了包括问诊、临床检查、X线检查以及在倾斜平台上测定PRT的诊断流程。大多数患者（n = 143，77%）可检测到PRT延长，提示存在神经肌肉功能缺陷。比较患侧和健侧下肢，77例患者（41%）在X线应力位片上显示距骨移位（p = 0.002）和距骨倾斜（p = 0.04）存在显著差异。在这77例患者中，只有15例（8%）有机械性问题的影像学证据。由于踝关节反复扭伤，多数情况下可预期存在创伤后本体感觉功能缺陷。一般而言，应采取保守治疗方法，包括进行特定训练以改善神经肌肉和本体感觉功能缺陷。
