用户偏好有可能促进假体的设计、控制和处方，但我们还不了解哪些生理因素驱动偏好，或者偏好是否与临床受益相关。单侧膝下截肢的受试者在定制的可变刚度假肢踝关节上行走，并在三种行走速度下操纵表盘以确定他们首选的假肢踝关节刚度。我们评估了拟人化，代谢，生物力学和性能为基础的描述符在刚度水平周围的每个主题的首选刚度。受试者在自选的跑步机行走速度下更喜欢较低的刚度值，并选择在踝关节刚度等于或高于其首选刚度的情况下在地上行走更快。首选刚度最大化假体和未受影响的关节之间的运动对称性，但没有显着相关的体重或代谢率。这些结果意味着，一些生理因素的权重更重时，确定首选的刚度，偏好可能与临床相关的改善步态。在线版本包含补充材料，可通过10.1186/s12984-021-00916-1获得。
User preference has the potential to facilitate the design, control, and prescription of prostheses, but we do not yet understand which physiological factors drive preference, or if preference is associated with clinical benefits. Subjects with unilateral below-knee amputation walked on a custom variable-stiffness prosthetic ankle and manipulated a dial to determine their preferred prosthetic ankle stiffness at three walking speeds. We evaluated anthropomorphic, metabolic, biomechanical, and performance-based descriptors at stiffness levels surrounding each subject’s preferred stiffness. Subjects preferred lower stiffness values at their self-selected treadmill walking speed, and elected to walk faster overground with ankle stiffness at or above their preferred stiffness. Preferred stiffness maximized the kinematic symmetry between prosthetic and unaffected joints, but was not significantly correlated with body mass or metabolic rate. These results imply that some physiological factors are weighted more heavily when determining preferred stiffness, and that preference may be associated with clinically relevant improvements in gait.
