    • A continuous passive motion device which may be used in providing physical therapy for a patient's knee by moving the patient's leg through a plurality of cycles of motion in a treatment session includes an “Oscillation Zone” range of motion feature that permits the machine to be operated in such a manner that the patient's knee is flexed and his leg extended through a critical or working range of motion more frequently than through the non-critical range of motion, or the remainder of the range of motion of the device, so as to increase the portion of time of a treatment session that is spent in the working range of motion. A preferred embodiment of the device allows the patient's knee to be flexed, extended and held in certain positions a predetermined number of times per cycle, so as to provide a treatment regimen which replicates the holding and stretching one might receive through physical therapy conducted by a therapist or a physician. A preferred embodiment of the invention also has “Soft Turns” capability, wherein the carriage holding the patient's leg is decelerated, at a controlled rate over a controlled distance, from the operational speed to zero, as the carriage approaches an extension or flexion limit, and wherein the carriage is accelerated in the same fashion as the carriage moves away from the extension or flexion limit.
    • 连续的被动运动装置可用于通过在治疗过程中通过多个运动周期移动患者的腿来为患者的膝盖提供物理治疗,包括允许机器操作的“振荡区”运动特征范围 使得患者的膝盖弯曲并且腿部比通过非临界运动范围或装置的运动范围的其余部分更频繁地延伸到关键或工作运动范围,以增加 在运动的工作范围内花费的治疗会话的时间部分。 该装置的优选实施例允许患者的膝盖在每个周期中弯曲,延伸并保持在某些位置预定次数,以便提供复制通过物理治疗进行的保持和拉伸的治疗方案 治疗师或医生。 本发明的优选实施例还具有“软匝”功能,其中,当滑架接近延伸或屈曲极限时,保持患者腿部的托架以受控距离的受控速度从操作速度减速到零, 并且其中滑架以与滑架远离伸出或弯曲极限移动相同的方式被加速。
