[0002] Hemiplegia, also known as hemiparalysis, is manifested as motor disorders of the upper and lower limbs, facial muscles and lower part of the tongue on the same side, and is a common symptom of acute cerebrovascular diseases. Spastic hemiplegia generally develops from flaccid hemiplegia, and its characteristic is obvious increased muscle tone. The extensor muscle groups of the upper and lower limbs are significantly paralyzed, and the muscle tone is significantly increased. Therefore, the wrist shows an inward flexion state, and the ankle and foot mostly show a foot drop state. There is a stiff resistance when moving the hand and foot. If the wrist joint and ankle joint of the patient are in a diseased state for a long time without movement, it is easy to cause disuse syndrome, resulting in muscle weakness and muscle atrophy at the wrist and ankle and foot, which is not conducive to the rehabilitation treatment of hemiplegic patients.

[0054] Furthermore, grips 4 are also arranged on both sides of the first support rod 1 to facilitate fixing the patient's body when the patient performs ankle joint training alone; a seat platform 5 is also movably arranged on the rod body of the first support rod 1 to facilitate the patient to choose to stand or sit for wrist and ankle joint training;

[0055] Refer to the Figure 1-2As shown, the wrist joint training mechanism 2 is movably connected to and used in cooperation with the top plate 101. Specifically, a chute 101-1 is provided on the top plate 101. In this embodiment, the chute 101-1 is circular and can also be an elliptical structure; a wrist joint training track 101-1A is provided on the wall of the chute 101-1. Here, the wrist joint training track 101-1 has the same shape as the chute 101-1, and the wrist joint training track 101-1A is adaptively connected to the wrist joint training mechanism 2. Specifically, the wrist joint training mechanism 2 is embedded in the wrist joint training track 101-1A and can slide freely therein;

[0056] Refer to Figures 3-5 As shown, the specific structure of the wrist joint training mechanism 2 is as follows: it includes a handheld part 201, which is convenient for patients to grasp during use; a sliding part 202, which is embedded in the wrist joint training track 101-1A and is rotatably connected to the handheld part 201. That is, the handheld part 201 can rotate 360° relative to the sliding part 202;

[0057] The handheld part 201 includes a handle 201-1 and a connecting ball 201-2 that are connected to each other; the sliding part 202 includes a sliding ball 202-1 and a connecting seat 202-2 that are connected to each other. The sliding ball 202-1 is embedded in the wrist joint training track 101-1A and can slide freely along the track. The connecting seat 202-2 is adapted to the connecting ball 201-2. That is, the connecting ball 201-2 is movably installed in the connecting seat 202-2, and the connecting ball 201-2 can rotate 360° in the connecting seat 202-2;

[0058] Preferably, an anti-slip pad can be fixedly wound on the handle 201-1 to increase the friction force for the patient to hold the handle 201-1 and avoid the situation that the handle 201-1 slips due to sweating of the hand during long-term training;

[0059] Furthermore, refer to Figure 5 As shown, the free end of the wrist joint training mechanism 2 is fixed to the top plate 101 through an elastic rope 7. Specifically, a rope-passing hole 201-3 is provided at the free end close to the handle 201-1, and the elastic rope 7 is movably passed through the rope-passing hole 201-3. The free end of the elastic rope 7 is fixed to the top plate 101 through a fixing piece;

[0060] One function of the elastic rope 7 is to connect the wrist joint training mechanism 2 and the top plate 101 together. Another function is that when the rehabilitation personnel perform wrist joint training, the elastic rope 7 can exert a reverse pulling force to further enhance the wrist joint training effect of the rehabilitation personnel;

[0061] Refer to Figures 6-7As shown in the figure, the ankle joint training machine 3 includes: a foot placement plate 301, a U-shaped limiting plate 302, and a triangular connecting piece 303; the foot placement plate 301 facilitates the rehabilitation personnel to place their feet on it during training, and the U-shaped limiting plate 302 functions to limit the left and right movement range of the foot placement plate 301 when the rehabilitation personnel perform inversion and eversion training;

[0062] The specific connection relationship is: the upper end of the triangular connecting piece 303 is rotatably connected to the foot placement plate 301, the lower end is connected to the U-shaped limiting plate 302, and the U-shaped limiting plate 302 is adapted to the foot placement plate 301, that is, the length of the foot placement plate 301 is greater than the length of the U-shaped limiting plate 302;

[0063] Further referring to Figure 6 As shown in the figure, considering that when the rehabilitation personnel perform inversion and eversion training, their feet are prone to displacement when directly placed on the foot placement plate 301, therefore, the present utility model is provided with a foot limiting groove 301-1 on the foot placement plate 301. When the rehabilitation personnel place their feet in the limiting groove 301-1 during training, the displacement of the feet can be prevented. And considering comfort, soft pads are provided at the bottom and around the foot limiting groove 301-1 to prevent injuries during the movement process;

[0064] Further referring to Figure 1 As shown in the figure, a plurality of limiting elastic bands 6 are further provided on the foot placement plate 301. The function of the limiting elastic bands 6 is that when the patient uses the foot placement plate 301, it can play a certain limiting role, and at the same time, the patient can move the front part of the foot upward to train the stability of the ankle joint;

[0065] The use process and principle of the wrist and ankle joint rehabilitation training device in this preferred embodiment are as follows: The rehabilitation training personnel can use this device to perform separate training or synchronous training of the wrist and ankle joints. During the training process, they can choose to stand or sit on the seat 5 for corresponding training;

[0066] Wrist joint training principle: The patient holds the handle 201-1 and drives the handle 201-1 and the connecting ball 201-2 to slide within the wrist joint training track 101-1A. At this time, the handle 201-1 rotates relative to the sliding ball 202-1 to adapt to different angles between the handle 201-1 and the wrist joint training track 101-1A; thereby realizing 360-degree rotation of the patient's wrist joint to achieve the training purpose; and during the training process, the elastic rope 7 can exert a reverse pulling force to further enhance the wrist joint training effect of the rehabilitation personnel;

[0067] Principle of ankle joint training: The rehabilitation personnel place the foot in the foot limiting groove 301-1, and drive the foot placement plate 301 to swing left and right through the angle of the rehabilitation personnel, so as to realize the eversion and inversion training of the foot; At this time, both sides of the U-shaped limiting plate 302 limit the foot placement plate 301, thereby restricting the foot placement plate 301 to swing within a fixed angle, and avoiding joint injuries of the rehabilitation personnel caused by too large a swinging amplitude.

[0068] Embodiment 2:

[0069] On the basis of Embodiment 1, considering that the swinging amplitude of the foot placement plate 301 left and right is fixed and inconvenient, and cannot be adaptively adjusted according to different rehabilitation personnel and training levels, resulting in poor training effects, this embodiment provides a U-shaped limiting plate structure that can adjust the swinging amplitude of the foot placement plate 301 left and right, so as to be adaptively adjusted according to different rehabilitation personnel and training levels, and achieve better training effects;

[0070] Specifically, referring to the attached Figures 7-8 As shown, the U-shaped limiting plate 302 includes: a limiting bottom plate 302-1, limiting side plates 302-2, and an adjusting member 302-3; The limiting side plates 302-2 are symmetrically and rotatably arranged on both sides of the limiting bottom plate 302-1. One end of the adjusting member 302-3 is hinged to the limiting bottom plate 302-1, and the other end is movably connected to the limiting side plate 302-2;

[0071] Specifically, the adjusting member 302-3 includes: a second support rod 302-3A and a plurality of hanging rings 302-3B. One end of the second support rod 302-3A is hinged to the limiting bottom plate 302-1. The hanging rings 302-3B are equidistantly arranged on the limiting side plate 302-2. The hanging rings 302-3B are movably connected to the other end of the second support rod 302-3A, that is, the other end of the second support rod 302-3A is movably connected to the hanging rings 302-3B through the hooks arranged thereon;

[0072] When it is necessary to adjust the swinging amplitude of the foot placement plate 301 left and right, first separate the second support rod 302-3A from the hanging ring 302-3B, and then pull the limiting side plate 302-2 outwards to increase the angle between the limiting side plate 302-2 and the limiting bottom plate 302-1. When the appropriate angle is adjusted, hang the second support rod 302-3A on the corresponding hanging ring 302-3B to complete the adjustment function. Here, it should be noted that the length of the foot placement plate 301 is not greater than the sum of the lengths of the limiting side plate 302-2 and the limiting bottom plate 302-1, so as to avoid the limiting side plate 302-2 losing the limiting effect on the limiting side plate 302-2 and avoid the problem of inability to complete ankle joint rehabilitation training.
