[0002] Good limb positioning is one of the important measures for early anti-spasm. This good limb positioning can make the joints after hemiplegia relatively stable, and can effectively prevent the typical spasm pattern of the upper limb flexors and lower limb extensors. It is also one of the methods to prevent the occurrence of pathological movement patterns in the future.

[0019] Reference Figure 1 and Figure 4In a preferred embodiment, two mounting members 704 are fixedly connected to the top of the base 1, and mounting holes are provided on the two mounting members 704. The same threaded rod 705 is rotatably connected in the two mounting holes through bearings, and the sliding table 702 is connected to the outside of the threaded rod 705 through threads, and one end of the threaded rod 705 is fixedly connected to an adjusting member 706.

The toggle rod 613 is released, and the coil spring 611 elastically recovers to drive the limiting tooth 614 to reset, locking the sliding seat 601. The rotating frame 602 is rotated to lower the mounting frame 603, so that the patient's foot is fixed between the two sliding members 606. The springs 605 on both sides push the foot to keep it vertical, maintain the natural tension of the muscles and the normal range of motion of the ankle joint, prevent foot drop and ankle deformation, and cushion the shock. When the patient performs toe flexion and dorsiflexion of the foot, the sliding members 606 in different directions will be driven to compress the spring 605. The spring 605 provides the patient with additional progressive resistance and elastic shock absorption, thereby improving the training effectiveness and safety of ankle flexion and extension.
