Description

Technical Field

[0002] For some patients with fractures or hemiplegia, after long-term lying and recuperation, their limb joints, especially the lower limb joints, will become stiff and inflexible. When conducting equipment-assisted training, it is necessary to carry out targeted training. Limb rehabilitation includes the early and late stages of recuperation. At present, most rehabilitation trainers do not have targeted training for different rehabilitation stages. In the early stages of rehabilitation, the lower limb joints, including the hip, knee, and ankle joints, cannot be trained with large twisting ranges, and the patient's muscles and joints are weak and cannot completely complete the twisting of the limb joints by their own muscles. Keeping the waist, legs, and lower limb joints immobile for a long time will have a negative impact on the rehabilitation of the waist, legs, and lower limb joints, which is not conducive to the recovery of motor skills and nerve perception.

[0003] However, the utility model has the following problems when actually used:

[0004] Most of the existing passive training devices for the waist and knee joints are twisting or turning devices, which lack restraint points for patients during training and require others to assist in training to achieve the purpose of rehabilitation training.
