Description

Technical Field

[0001] The present invention belongs to the technical field of rehabilitation training devices, and particularly relates to a limb muscle exercise rehabilitation training device. Background Art

[0002] At present, during the postoperative recovery of limbs and the rehabilitation of hemiplegic patients' limbs, or after some patients receive long-term treatment in the hospital, limb dysfunction generally occurs. These patients need to stay in bed for rest. However, long-term bed rest will also bring certain adverse reactions to the body, resulting in physical weakness, which is not conducive to future recovery and there is a certain sub-healthy state. At the same time, for patients with minor injuries or those who have recovered to a certain extent and do not need to stay in bed, a certain intensity of strength training is necessary. Otherwise, long-term bed rest will lead to muscle atrophy, joint stiffness, and even cause disuse paralysis of the patient's limbs, affecting the patient's health and being unfavorable for the patient's later recovery. Therefore, the rehabilitation treatment of patients with limb dysfunction and the like is very important, and a targeted limb rehabilitation training device needs to be provided.

[0003] Most of the existing limb rehabilitation training devices only set a single limb training item, with a single function. And because the patient's body is in a static lying state for a long time, it is easy to cause numbness and atrophy of the back muscles. If the back muscles can be massaged when the patient is exercising the limbs, the patient's back muscles will be relaxed, promoting blood circulation. This will not only help the recovery of the limbs, but also increase the patient's physical and mental pleasure, making it easier for the patient to persevere, improving the rehabilitation training effect, and helping the patient recover to a healthy and functional level close to their normal state.
