进行研究的原因：对轻度跛行的主观评价已被证明具有较差的观察者间信度。传统的客观跛行评估方法需要专门的条件和设备。无线惯性传感器系统已经发展到可以简单、快速、客观地检测在地面上小跑的马的跛行。目的：本研究的目的是比较惯性传感器系统的灵敏度和由经验丰富的马从业人员进行的主观评估在检测马的跛行。我们假设，惯性传感器系统将识别跛行在较低水平的脚底压力比3经验丰富的马兽医的共识。方法：为15匹马配上特制的足部压足诱导鞋。同时由3名马兽医和无线惯性传感器系统对马匹进行评估。马接受多次试验：1)在插入螺钉之前；2)插入螺丝后要刚好碰到鞋底；3)拧紧后的螺丝在半转增量。使用Wilcoxon试验比较了惯性传感器和3名马兽医一致同意的正确肢体跛行识别所需的螺钉转数。结果：惯性传感系统比3位兽医更少地选择了诱发性跛行肢体(P
Reasons for performing study: Subjective evaluation of mild lameness has been shown to have poor interobserver reliability. Traditional methods of objective lameness evaluation require specialised conditions and equipment. Wireless inertial sensor systems have been developed to allow for simple, rapid, objective lameness detection in horses trotted over ground.Objective: The purpose of this study was to compare the sensitivities of an inertial sensor system and subjective evaluation performed by experienced equine practitioners at detecting lameness in horses. We hypothesised that the inertial sensor system would identify lameness at a lower level of sole pressure than a consensus of 3 experienced equine veterinarians.Methods: Fifteen horses were fitted with special shoes that allowed for lameness induction via sole pressure. Horses were simultaneously evaluated by 3 equine veterinarians and a wireless inertial sensor system. Horses were subjected to multiple trials: 1) before inserting the screw; 2) after inserting the screw to just touch the sole; and 3) after tightening the screw in half turn increments. The number of screw turns required for lameness identification in the correct limb by the inertial sensors and by consensus of 3 equine veterinarians was compared using the Wilcoxon test.Results: The inertial sensor system selected the limb with the induced lameness after fewer screw turns than did the 3 veterinarians (P
