[0002] With the continuous development of modern medicine and rehabilitation technology, more and more hemiplegic patients are receiving professional treatment through rehabilitation training equipment to promote the recovery of limb function. Hemiplegia is usually caused by stroke, brain injury or spinal cord injury. During the rehabilitation process, especially the rehabilitation of the upper limbs, patients face problems such as limited activity, insufficient muscle strength and joint stiffness. In response to these problems, various upper limb rehabilitation training equipment has emerged to help hemiplegic patients carry out rehabilitation training and restore the basic function of their upper limbs.

[0003] Upper limb pressing trainers have become a common rehabilitation aid in the market. They mainly help patients exercise upper limb muscle strength and joint mobility by simulating pressing movements. However, existing upper limb pressing trainers have some shortcomings, especially in terms of adjusting the stretching intensity. Upper limb pressing trainers usually only provide fixed training modes and intensities and cannot be personalized according to the specific situation of different patients. When using these devices, patients may feel that the stretching intensity is insufficient or excessive due to differences in muscle strength, which limits the rehabilitation effect and fails to effectively stimulate the patient's muscles and nervous system, thus affecting the rehabilitation process.

[0004] Therefore, this application provides a rehabilitation training device for hemiplegic patients to solve the above problems. Utility Model Content
