Description

Technical Field

[0001] The utility model belongs to the technical field of lower limb training, in particular to a lower limb training device with a swinging and lifting auxiliary mechanism. Background Art

[0002] The lower limb trainer is a medical device designed for lower limb motor function rehabilitation, aiming to simulate daily activities, enhance muscle strength and improve joint mobility.

[0003] Traditional lower limb trainers usually only use a swinging method to train the patient's legs, resulting in a relatively single training function. It is difficult to train the patient's leg bending, so other trainers need to be replaced to perform leg bending training. Not only does it require patients to frequently change trainers, but a single training is difficult to achieve good training results. Therefore, we proposed a lower limb trainer with a swinging and lifting auxiliary mechanism. Utility Model Content
