[0002] After the treatment of cerebral hemorrhage patients, the limb function will be damaged. The patients will have sequelae of cerebral hemorrhage such as incorrect posture, stiff knees, tiptoeing, inability to flex knees and cross legs. It is very difficult to restore the limb function, causing walking difficulties and even paralysis in bed. Therefore, cerebral hemorrhage patients urgently need foot rehabilitation, which needs to be gradual and difficult to achieve immediate recovery through surgery or other corrective treatments.

[0003] At present, foot rehabilitation is mainly achieved through treatment in rehabilitation centers. Due to the issue of medical expenses, most patients choose to do self-rehabilitation training at home. However, due to unscientific training methods and insufficient training volume, many patients miss the best recovery time. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a foot rehabilitation trainer for cerebral hemorrhage.

For patients with milder cerebral hemorrhage, when training in a sitting position, the leg support plate can be driven to rotate upward by the leg on the healthy side to perform knee flexion rehabilitation training.

[0022] 2. After the paralyzed foot is placed on the foot correction board, the pressure plate under the sole of the foot will be squeezed and lifted upward by the sole of the foot. The foot correction board will tilt due to the incorrect posture of the paralyzed foot. The foot shape positioning plate on the front side of the foot correction board will replicate this foot tilt. The tilted foot correction board is corrected by pressing down the rotating column, and the pressure plate under the sole of the foot is pressed down at the same time. The pressure of the pressure plate under the sole of the foot can flatten the paralyzed foot for subsequent foot rehabilitation training.

[0023] 3. Driven by the gear drive shaft, the toe plate regularly drives the toes of the left and right feet to be lifted and lowered synchronously. The synchronous movement can better activate the motor nerves of the paralyzed toes. At the same time, when the toe plate rotates, it will drive the toe reset rod to move forward and backward. The toe reset rod will push the paralyzed inward-adducted toes forward, so that the inward-adducted toes can be spread out, completing the rehabilitation training of the toes.

[0024] 4.

At this time, the positioning hole of the support frame and the ball head plane of the universal rotating column are at the same center of the circle, simulating the ankle to drive the sole of the foot to move. Driven by the vertical board connecting shaft, the rear foot support frames on both sides regularly drive the left and right feet to perform cross-legged training.

[0025] 5. Manually rotate the size adjustment piece and the adjustment gear drives the size adjustment gear rod on the forefoot sole to move. According to the size of the patient's foot, adjust the distance between the sole correction plate and the heel elastic groove, and then use the foot binding strap to fix it. At the same time, when the adjustment gear rotates, the positioning wedge block at the bottom of the locking column will jam the adjustment gear to prevent the sole correction plate from slipping and loosening during rehabilitation training. After the training, untie the foot binding strap and pull up the locking column to disengage the positioning wedge block from the adjustment gear, so that the sole of the foot can be detached.

[0026] 6. The motor gear is designed with teeth for only a section of arc length. When it rotates, it will periodically drive the transmission wheel group to rotate for a short arc length, and then regularly drive the vertical plate connecting shaft and the gear rod driving shaft to rotate, thereby realizing toe rehabilitation training and foot-lifting training for patients with cerebral hemorrhage.
