Description

Electric posture correction weight loss walking training device

technical field

The utility model relates to the technical field of rehabilitation medical equipment, in particular to an electric posture correction weight loss walking training device.

Background technique

Human walking is a movement in which the body's center of gravity moves by stepping on the ground to obtain the ground reaction force formed by friction with the ground. During normal walking, the vertical upward component force curve of the ground reaction force presents two peaks, which is a bimodal curve, which is medically called the vertical reaction force bimodality in walking. The bimodality of the walking ground reaction force directly reflects the gait and is an important indicator to measure normal walking. Walking with good bimodality 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 center of gravity of the body relatively stably. Further, from medical clinical research, it is known that when the body trunk posture is abnormal, the valley between the double peaks of the vertical upward component force of the ground reaction force during walking changes from deep to shallow, and serious abnormalities may also lead to double vertical reaction force during walking. The kurtosis disappeared, however, with the correction of abnormal trunk posture, simultaneous walking training improved the bimodal depression caused by the abnormal trunk posture. In modern society, the average life expectancy of human beings continues to increase, and the aging of the population is inevitable. Among the elderly, there are common elderly people with abnormal trunk postures such as severe kyphosis, chest bending, and lumbar anteversion due to poor sagittal plane stability due to aging, and postural scoliosis patients with poor coronal plane stability. A patient with abnormal trunk posture in the sagittal and coronal planes caused by the immobility of the diseased hemilateral. According to the results of the above medical clinical studies, for those with abnormal trunk posture on the sagittal plane and coronal plane, the walking stability can be improved through posture correction walking training.

On the other hand, for hemiplegic patients caused by stroke and other diseases, using a suspension device to allow the patient to stand on an electric treadmill for weight loss walking training is a new method in the field of walking rehabilitation in recent years. It can drive the patient to step subconsciously, activate the motor cortex and spinal cord rhythmic movement center, and exercise the patient's joint function and muscle strength. However, the patient's movement on the electric treadmill is with the movement of the treadmill, and the body passively lifts the foot and moves the lower limb joints and other actions similar to walking, and does not get the reaction force formed by the friction with the ground without stepping on the ground. The effect of shifting the center of gravity. From the perspective of cognitive function, the speed of a person's walking in the actual environment can be reflected in the person's field of vision, and the person's vision and walking speed are linked. linkage. That is to say, the weight loss walking training on the electric treadmill cannot completely replace the standing walking training carried out by the therapist holding the patient. Therefore, after the weight loss walking training on the electric treadmill and other devices, the patient needs to switch to the mobile weight loss walking training to achieve a complete walking after the sensory function of walking, joint function and muscle strength have recovered to a certain extent. training process. However, in the traditional mobile walking trainer, when the patient's body leans forward, and the patient's feet cannot keep up with the body's center of gravity, it will cause the forward thrust to increase and the walker to slip forward, resulting in a forward-squatting fall accident. occur. Especially for walking training patients with severely insufficient support, due to insufficient standing muscles of both feet, the center of gravity of the body is prone to move down, resulting in the accident of falling down. The electric-controlled mobile walking training device can reduce the occurrence of front-squatting or falling-down accidents.
