[0002] At present, for most patients with chronic knee pain, those recovering from sports injuries, and those recovering from knee surgery, rehabilitation-related training and equipment mainly involve muscle stretching or strength training in directions such as knee flexion and extension. However, it is difficult to carry out targeted training and adjustment for the overall lower limb biomechanical line correction and the dynamic force line during functional movements. Generally, lower limb stability training under the supervision of a rehabilitation therapist is used for correction. However, only verbal guidance or the therapist applies resistance to the inner and outer sides of the patient's knee joint. On the one hand, it is difficult for patients to feel the correct force, and the training quality and efficiency are low. In addition, the training intensity cannot be quantified, and it is difficult to compare before and after the training cycle. On the other hand, for the therapist himself, he needs to squat continuously and adjust dynamically, which is labor-intensive and prone to fatigue or injury.

[0003] It is impossible to perform quantitative corrective training of the knee joint force line from the coronal plane and dynamic and static angles according to the specific conditions of the patients, and it is also impossible to adjust the position and size of the resistance to meet the needs of different patients.
