Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training technology, and more specifically, to a rehabilitation training device for hemiplegic patients. Background Technology

[0002] Hemiplegia, also known as paralysis of one side of the body, refers to motor dysfunction of one side of the upper and lower limbs, facial muscles, and lower tongue muscles. It is a common symptom of acute cerebrovascular disease. Mild hemiplegic patients can still move, but when walking, the upper limb is often flexed and the lower limb is extended, with the paralyzed lower limb making a semi-circular step with each step; this distinctive gait is called hemiplegic gait. Severe cases often result in bedridden patients who lose their ability to live independently. Based on the degree of hemiplegia, it can be divided into mild hemiplegia, incomplete hemiplegia, and complete hemiplegia. Mild hemiplegia: characterized by muscle weakness, with a muscle strength of 4-5, generally not affecting daily life. Incomplete hemiplegia is more severe than mild hemiplegia, affecting a larger area, with a muscle strength of 2-4. Complete hemiplegia: with a muscle strength of 0-1, the paralyzed limb is completely unable to move.

[0003] Existing patent CN 221655756 U discloses an ankle rehabilitation training device for hemiplegic patients. By incorporating a worm gear and worm shaft, the angle, orientation, and position of the foot pedal can be easily adjusted, and the device is symmetrical front and back. The patient's feet are secured with straps, and they walk upwards from their feet, ensuring the overall alignment and stability of the knee, hip, pelvis, and spine. This lays a solid foundation for dynamic standing balance and walking function training. However, this device requires the patient to adjust its angle before stepping on it, which can cause instability. Furthermore, the angle may not be suitable for the patient's tolerance, and the device's function is relatively limited.
