Description

technical field [0001] The invention relates to a rehabilitation device, in particular to a wrist rehabilitation device. Background technique [0002] With the aggravation of aging, the loss of limb function caused by stroke disease has brought a heavy burden to the patient's family and society. In addition, the related complications caused by diseases such as stroke are also increasing, especially the loss of upper limb motor function, which greatly affects the ability of patients to live in daily life. The clinical rehabilitation method for hemiplegic patients is that the rehabilitation physician spends a lot of time on the patient to perform one-on-one treatment with bare hands, and the effect of training and rehabilitation largely depends on the clinical experience of the rehabilitation physician.

Problems solved by technology

In addition, related complications caused by stroke and other diseases are also increasing, especially the loss of upper limb motor function, which greatly affects the ability of patients in daily life

The clinical rehabilitation method for hemiplegia patients is that the rehabilitation physician spends a lot of time on the patient with one-on-one treatment with bare hands, and the effect of training and rehabilitation largely depends on the clinical experience of the rehabilitation physician. In addition, in the traditional rehabilitation treatment process In , medical care is expensive due to lack of skilled nursing staff

If the rehabilitation physician is inexperienced, the rehabilitation training method is not accurate enough, and the training intensity cannot be controlled, the patient will eventually miss the most favorable time for rehabilitation treatment, thus failing to obtain the ideal rehabilitation effect, and even causing secondary injuries

[0003] At present, most of the wrist rehabilitation devices are used by patients to realize exercise rehabilitation training by holding the end handle of the rehabilitation device. However, for many severe patients, their entire affected limbs cannot realize the hand grip function by themselves.
