Description

Two degrees of freedom suspension posture correction weight loss walking trainer

technical field

The invention relates to the technical field of rehabilitation medical equipment, in particular to a two-degree-of-freedom suspension type posture correction weight loss walking trainer.

Background technique

Human walking is a movement in which the body's center of gravity is moved by pedaling on the ground to obtain the ground reaction force formed by friction with the ground. During normal walking, the vertical upward force component curve of the ground reaction force presents two peaks, that is, a bimodal curve, which is medically called the bimodality of the vertical reaction force in walking. The bimodality of walking ground reaction force directly reflects gait and is an important index to measure normal walking. Good bimodal walking means that the valley between the two peaks of the bimodal curve of the ground vertical reaction force during walking is deep, that is, the vertical reaction force during walking can move the body's center of gravity relatively stably. Further medical clinical research shows that when the trunk posture is abnormal, the valley between the two peaks of the vertical upward component of the ground reaction force during walking changes from deep to shallow, and severe abnormalities may also lead to double peaks of the vertical reaction force during walking. However, walking training simultaneously with the correction of abnormal trunk posture can improve the bimodal hypotension caused by abnormal trunk posture.

On the other hand, for patients with hemiplegia caused by stroke and other diseases, it is a new method in the field of walking rehabilitation in recent years to allow patients to stand on an electric treadmill with a suspension device for weight loss walking training. It can drive the patient to step subconsciously, activate the motor cortex and the rhythmic movement center of the spinal cord, and exercise the joint function and muscle strength of the patient. However, the movement of the patient on the electric treadmill follows the movement of the platform, and the body passively performs actions similar to walking such as lifting the foot and moving the joints of the lower limbs. The effect of shifting the center of gravity. From the perspective of cognitive function, the speed of people's walking in the actual environment can be reflected in people's vision, and people's vision is linked with walking speed, while the movement speed of patients on electric treadmills has no relationship with vision. linkage. That is to say, the weight-reducing walking training on the electric treadmill cannot completely replace the standing and walking training performed by the therapist holding the patient by hand. Therefore, after the patient has recovered the sensory function of walking, joint function and muscle strength through weight-reducing walking training on electric treadmills and other devices, he needs to switch to mobile weight-reducing walking training in order to achieve a complete walking. training process. However, the traditional mobile walking trainer has the problem that when the patient's body leans forward, and the patient's feet cannot keep up with the center of gravity of the body, the forward thrust will increase and the walker will slide forward, leading to a forward fall accident. occur.
