Human balance dynamic evaluating method and device

Abstract

The invention relates to a human balance dynamic evaluating method and device. The device is composed of a force plate, a swing support, a long shaft, a left supporting frame, a right supporting frame, a DC motor, a transmission mechanism and a base. After a testing platform is reset, signal output of an initial position is obtained through a force sensor, signal output at all moments in the test cycle is obtained through the force sensor in the swing process of the force plate, an upper computer obtains center-of-mass coordinates through the mechanical relationship after the signal output at all moments in the cycle is converted into signal output under a reference coordinate system, and the disease status of a patient is judged according to the center-of-mass change trajectory chart. The application range is wide, and the device is simple in structure, easy to operate, light in weight and low in cost on the premise of ensuring the strength. The hollowed-out design is adopted for the middle of the swing device, the motor is prevented from touching an upper plate, and the weight can be reduced. The testing method is simple, and the more accurate testing experimental method is provided on the basis of ensuring the stability and safety of the platform.

Description

technical field [0001] The invention belongs to the technical field of gait detection equipment, and relates to a method for dynamic evaluation of human body balance and a device thereof. Background technique [0002] my country is a country with a high incidence of cerebrovascular diseases. In recent years, test results have shown that the annual death toll of stroke has exceeded nearly 2 million, and there is a trend of younger people. Due to damage to the central nervous system, most stroke patients will experience balance dysfunction, resulting in poor body and limb control and inability to take care of themselves in daily life. Therefore, exploring an accurate and effective method for detecting the motor balance ability of stroke patients has a very important guiding role in the evaluation and treatment of patients. At present, the most common method is to use the three-dimensional force measuring platform system to evaluate the balance ability of patients with stroke-...

Problems solved by technology

With the development of sports biomechanics and the need for applications in related fields, more and more researchers have begun to study this type of measurement equipment, which has greatly improved the sensitivity and stability of the platform, but currently The three-dimensional force measuring platforms of the company are all statically placed on the plane, and the balance algorithm and analysis are also based on static state. The degree of discrimination for patients' conditions is low, and the degree of discrimination for early balance impairments such as Alzheimer's disease is insufficient. Provide sufficient clinical discrimination information in terms of prevention and germination diagnosis
