Knee bending trainer

Abstract

The invention discloses a knee bending trainer, which performs knee bending training by fixing feet and sliding in a rail groove, and can adjust the sliding resistance to adapt to the speed and limitquantity of knee bending movement of different patients. According to the technical scheme, the knee bending trainer is characterized by comprising a base and two foot fixing mechanisms, two parallelrail grooves are formed in the base, the two foot fixing mechanisms are connected with the two rail grooves in a sliding mode respectively, and connecting mechanisms are arranged between the foot fixing mechanisms and the rail grooves; a limiting mechanism used for adjusting the sliding resistance of the foot fixing mechanism is arranged in the rail groove, and a fixing structure used for fixing the base to the ground is further arranged at the bottom of the base. The patient can perform knee bending training under the sitting position by himself / herself, manual traction is not needed, manpower is saved, the patient can adjust the training posture and strength by himself / herself, and rehabilitation is better facilitated.

Description

technical field [0001] The invention relates to the field of rehabilitation equipment, in particular to a knee flexion trainer. Background technique [0002] For patients with paralysis of the left limbs left after stroke, with the recovery of motor function, especially when they reach Brunnstrom stage III, due to the increased excitability of antigravity muscles, the lower limbs often show extensor spasticity, with limited knee flexion in sitting position and ankle joint pain. Dorsiflexion is limited, and various neuromuscular facilitation techniques are used clinically to suppress spasticity patterns and induce separation movements. The enhancement of antagonist muscle strength plays a key role in inhibiting the further increase of antigravity muscle tension. As the main antagonistic muscle of the quadriceps femoris, the hamstring muscle often does not recover well after a stroke, leading to a series of problems such as poor stability of the knee joint and knee hyperexten...

AI Technical Summary

Problems solved by technology

As the main antagonistic muscle of the quadriceps femoris, the hamstring muscle often does not recover well after a stroke, leading to a series of problems such as poor stability of the knee joint and knee hyperextension, and it is difficult to choose conventional manual training and equipment training methods Proper body position and appropriate resistance. For example, it is difficult to provide power-assisted exercise when the muscle strength is below level 3, and it is difficult to provide resistance training when the muscle strength is level 3 or above, making training difficult
