Efficacy of knee flexion contracture treatment protocols is dependent on the torque applied to the joint, but to date, no published reports have evaluated the torque applied by the available treatment options. The purpose of this study was to measure the torque applied by physical therapists (PTs), home exercises, and mechanical therapy devices. An instrumented test leg recorded peak torque applied by 14 PTs performing knee extension mobilization, 2 home exercises, and 3 types of mechanical therapy (dynamic splint, static progressive stretch, and patient-actuated serial stretch). Physical therapists applied 68.0 N m, patient-actuated serial stretch mechanical therapy applied 53.0 N m, and the other therapies ranged between 4.6 and 12.4 N m. The reported torque values can be used to help improve the efficacy of flexion contracture treatment protocols.
膝关节屈曲挛缩治疗方案的疗效取决于施加在关节上的扭矩，但迄今为止，尚无发表的报告评估现有治疗选择所施加的扭矩。本研究的目的是测量物理治疗师（PT）、家庭运动和机械治疗设备施加的扭矩。一个仪器化的测试腿记录了 14 名 PT 进行膝关节伸展松动时施加的峰值扭矩、2 项家庭运动和 3 种机械治疗（动态夹板、静态渐进拉伸和患者驱动的连续拉伸）。物理治疗师施加了 68.0 Nm，患者驱动的连续拉伸机械治疗施加了 53.0 Nm，其他治疗方法在 4.6 到 12.4 Nm 之间。报告的扭矩值可用于帮助提高屈曲挛缩治疗方案的疗效。
