Feature Extraction Method of Biomechanical Information

Abstract

The invention discloses a comprehensive evaluation method for movement functions based on a stroke patient. The comprehensive evaluation method comprises the following steps: acquiring biomechanical information in the movement process of the patient through acquiring equipment, wherein the biomechanical information comprises attitude information, electromyography information and plantar pressure information; constructing a human body limb mechanical model according to the movement process of the patient; fitting the biomechanical information by adopting a Bayesian decision-making function mode according to the biomechanical information as well as weight information corresponding to different parts in the human body limb mechanical model; performing feature extraction on the fitted biomechanical information. With the adoption of the comprehensive evaluation method disclosed by the invention, the attitude information, the electromyography information and the plantar pressure information are integrated and are used for quantitatively evaluating patient movement control and complete validity, and objectively, accurately and quantitatively evaluating patient posture control abilities, so that the rehabilitation diagnosis and treatment become visual and quantifiable, the clinical judgment of falling risks is helped, the life activity range of the patient is determined, and the treatment potential and the treatment direction of the patient are determined.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a feature extraction method of biomechanical information. Background technique [0002] Stroke is also called cerebral apoplexy. Stroke is a disease with a high morbidity rate. Symptoms such as hemiplegia, mental decline, dizziness, and aphasia directly affect the quality of life of patients and bring great difficulties to family and work. Therefore, stroke patients should take rehabilitation training as soon as possible. [0003] The human limbs are composed of complex muscles, ligaments, bones, etc. Therefore, to study the stress state of the limbs and the trunk in different states, it is necessary to consider the posture of the human body, the force of the soles, the quality of each part, and the stress of joints and muscles. power state. Correspondingly, in the process of rehabilitation training, stroke patients often need to monitor the patient's biomechanical informatio...

Problems solved by technology

Correspondingly, in the process of rehabilitation training, stroke patients often need to monitor the patient's biomechanical information in real time through collection equipment, so as to provide the basic basis for doctors to correctly diagnose the disease and formulate scientific rehabilitation training programs. However, at present, domestic and foreign Insufficient research on joints and muscles in the process of limb movement
