非西方文化中的患者通常会拒绝治疗导致屈曲受限的关节疾病，因为这些患者的日常生活活动需要髋部、膝部或踝部的更大范围的运动。然而，有关大范围运动活动（例如蹲下、跪下和盘腿坐）所需的关节运动学的信息有限，因此很难设计出满足这些人群需求的假肢植入物。因此，这项工作的目标是在印度受试者进行日常生活活动时生成髋关节、膝关节和踝关节的三维运动学。 30 名健康的印度受试者（平均年龄：48.2 +/- 7.6 岁）被要求进行六次以下活动的试验：蹲下、跪下和盘腿坐。使用电磁运动跟踪设备收集的运动学数据计算关节处的浮动轴角度，接收器位于受试者的脚、小腿、大腿和骶骨上。脚跟朝上蹲下时，膝关节平均最大弯曲度为 157 度 +/- 6 度。脚后跟平蹲时，平均最大髋部屈曲角度可达 95 度 +/- 27 度。与此活动相关的高标准偏差强调了不同受试者所需的最大髋部屈曲角度的大范围。盘腿坐姿活动时踝关节平均屈曲范围达到 58 度+/- 14 度。执行所研究的活动所需的运动范围大于目前大多数关节假体提供的运动范围，这表明需要大运动范围的植入物设计。 (c) 2006 年骨科研究学会。
Treatment of joint disease that results in limited flexion is often rejected by patients in non-Western cultures whose activities of daily living require a higher range of motion at the hip, knee, or ankle. However, limited information is available about the joint kinematics required for high range of motion activities, such as squatting, kneeling, and sitting cross-legged, making it difficult to design prosthetic implants that will meet the needs of these populations. Therefore, the objective of this work was to generate three-dimensional kinematics at the hip, knee, and ankle joints of Indian subjects while performing activities of daily living. Thirty healthy Indian subjects (average age: 48.2 +/- 7.6 years) were asked to perform six trials of the following activities: squatting, kneeling, and sitting cross-legged. Floating axis angles were calculated at the joints using the kinematic data collected by an electromagnetic motion tracking device with receivers located on the subject's foot, shank, thigh, and sacrum. A mean maximum flexion of 157 degrees +/- 6 degrees at the knee joint was required for squatting with heels up. Mean maximum hip flexion angles reached up to 95 degrees +/- 27 degrees for squatting with heels flat. The high standard deviation associated with this activity underscored the large range in maximum hip flexion angles required by different subjects. Mean ankle range of flexion reached 58 degrees +/- 14 degrees for the sitting cross-legged activity. The ranges of motion required to perform the activities studied are greater than that provided by most currently available joint prostheses, demonstrating the need for high range of motion implant design.
