Active partial body weight support treadmill training device and active partial body weight support treadmill training method

Abstract

The invention relates to an active partial body weight support treadmill training device and an active partial body weight support treadmill training method. The device comprises a force sensor, a support, a treadmill, and a partial body weight support mechanism. During the training, a patient is positioned on the treadmill and is connected to a steel wire rope through a sling, one end of the steel wire rope is provided with a winch which can adjust the length of the steel wire rope according to the height of the patient, while the other end is connected to the partial body weight support mechanism which is used for providing a partial body weight support force, and the partial body weight support force can be given according to the requirement of a doctor. During the whole training process, the force sensor is used to detect the actual partial body weight support force and feed back the actual partial body weight support force to a virtual instrument to realize closed-loop control, so that the constancy of the partial body weight support force is ensured. The active partial body weight support method can effectively improve the effect of partial body weight support treadmill training, has simple operation, and is suitable for rehabilitation training in hospitals and families.

Description

technical field [0001] The invention relates to an active weight-reducing walking training device and method, which are mainly used for lower limb weight-reducing walking training of patients with spinal cord injuries. technical background [0002] With the increase of modern means of transportation, the increase of traffic accidents, the increase of sports injuries, and the existence of some other injury factors, the number of patients with spinal cord injury is increasing rapidly, which greatly endangers human health. Medical theory and practice have proved that in addition to early surgical treatment and drug treatment, weight loss walking training (BWST) has become an important means of treating patients with spinal cord injury. [0003] In weight loss walking training, since the patient cannot support his own body weight, other methods are needed to unload the patient's own weight. In the process of rehabilitation training, as the patient gradually recovers, the require...

Problems solved by technology

At present, from the research situation at home and abroad, although the way of walking training has changed from the physical therapist's manual guidance of the patient's leg training to the use of lower limb rehabilitation robots for automatic training, most of the weight loss methods remain in passive weight loss, that is, using counterweights. In this weight reduction method, the number or size of the counterweights needs to be adjusted to change the weight, which requires a lot of physical strength of the operator and it is difficult to achieve small adjustments, and because the training is affected by the counterweights themselves Influenced by inertia, resulting in a large error in the weight reduction provided by it
