在安装假肢时，假肢医生将他们对患者步态的视觉评估信息与患者传达的感知和偏好融合在一起。在这项研究中，我们试图同时和独立地评估患者和修复师对使用定制可变刚度假体的假肢僵硬的偏好。在实验的第一部分，七名膝盖以下截肢的受试者在设置为随机僵硬的可变僵硬假肢上行走，而几名假肢受试者同时观察他们的步态。每次试验后，截肢受试者和假肢受试者指出他们更喜欢的僵硬程度的变化(增加或减少)。这一范式使我们能够同时测量截肢者和假肢者的偏好，并提供了一个表明他们偏好一致性的可靠性指标。在实验的第二部分，被截肢的受试者被指示与一名假肢受试者进行口头交流，以达到双方都喜欢的僵硬。平均而言，假肢患者的僵硬程度比截肢者高26%(p <； 0.001)，但这取决于截肢者(p <； 0.001)。假肢患者的偏好一致性也明显低于截肢者(截肢者的CV为5.6%，假肢患者的CV为23%；p = 0.014)。双方的偏好似乎是由特定的患者-假肢医生动态决定的，没有出现明确的趋势。
When fitting prosthetic feet, prosthetists fuse information from their visual assessment of patient gait with the patient’s communicated perceptions and preferences. In this study, we sought to simultaneously and independently assess patient and prosthetist preference for prosthetic foot stiffness using a custom variable-stiffness prosthesis. In the first part of the experiment, seven subjects with below-knee amputation walked on the variable-stiffness prosthetic foot set to a randomized stiffness, while several prosthetist subjects simultaneously observed their gait. After each trial, the amputee subjects and prosthetist subjects indicated the change to stiffness that they would prefer (increase or decrease). This paradigm allowed us to simultaneously measure amputee subject and prosthetist subject preferences, and provided a reliability index indicating the consistency of their preferences. In the second part of the experiment, amputee subjects were instructed to communicate verbally with one prosthetist subject to arrive at a mutually preferred stiffness. On average, prosthetist subjects preferred a 26% higher stiffness than amputee subjects (p < 0.001), though this depended on the amputee subject (p < 0.001). Prosthetist subjects were also considerably less consistent than amputee subjects in their preferences (CV of 5.6% for amputee subjects, CV of 23% for prosthetist subjects; p = 0.014). Mutual preference seemed to be dictated by the specific patient-prosthetist dynamic, and no clear trends emerged.
