Muscle force assessment method and device and muscle rehabilitation training tracking and assessment method and system

Abstract

The invention relates to the technical field of sports medicine and provides a muscle force assessment method and device and a muscle rehabilitation training tracking and assessment method and system. The muscle force assessment method includes the steps that image collection: ultrasonic equipment is adopted for collecting a muscle contraction image video in the moving process of a patient in real time; image preprocessing: framing is performed on the collected muscle contraction image video, so that interesting image information is extracted and the image contrast is adjusted; motion field extraction: a motion assessment method is adopted for calculating a motion field of every two adjacent frames in the image, and the motion fields represent spatial-temporal changes of an image gray value in the x direction and the y direction; a muscular movement range curve is obtained: a quantized index is extracted from the motion fields, and the muscular movement range curve is calculated in a fitting mode and serves as a reference standard of muscle force assessment. The ultrasonic equipment is used for collecting the muscle image, the muscle assessment method and device are simple and visual, requirements for a doctor and the patient are relatively reduced, and the processes of assessing muscle force are simplified.

Description

【Technical field】 [0001] The invention relates to the technical field of sports medicine, in particular to a muscle strength evaluation method and device, and a muscle rehabilitation training tracking evaluation method and system. 【Background technique】 [0002] The movement of humans or animals involves the activation and control of muscle strength. Understanding the mechanism behind the generation and control of muscle strength is of vital significance for the study of sports medicine and rehabilitation functions. Muscle strength is generally related to muscle function, potential work efficiency, and quality of life. The assessment of muscle strength can be used to identify whether there is injury or disability, determine whether the patient is eligible for treatment, or track the patient's treatment effect, that is, the muscle rehabilitation of patients with movement disorders is closely related to their muscle strength. However, it is not easy to directly measure muscle...

Problems solved by technology

How much resistance is exerted on the patient during manual muscle strength assessment, and how to objectively assess the muscle strength level, not ordinary doctors can make correct assessments, and neurologists with special training are required to complete the assessment, which requires both patients and doctors Higher and highly subjective; simple instrument tests mainly include gripmeters, pinchometers, tension meters, etc. Each instrument can only target specific muscle functions, the scope of application is not wide, and it cannot evaluate a specific muscle; EMG signal is an electrophysiological parameter that reflects muscle activity and can only be used as an indirect indicator of muscle strength evaluation, which is susceptible to interference, especially it is difficult to distinguish the peripheral and deep muscle effects of the target muscle
