Spasm sensor based on muscle tension detection

Abstract

The invention relates to a spasm sensor based on muscle tension detection. The spasm sensor comprises a muscle force transmitting module for collecting the body surface muscle tension, a force-sensitive unit module for adjusting the strength of contact between the muscle force transmitting module and the body muscle, a detection module for receiving and processing sensor data and displaying spasmfeature information finally, and a housing module for installing the muscle force transmitting module, the force-sensitive unit module and the detection module, wherein the muscle force transmitting module is connected to the lower end of the housing module, and the force-sensitive unit module and the detection module are located at the upper end of the muscle force transmitting module and connected with the upper end of the housing module. By means of the spasm sensor, the amplitude and frequency of the muscle tension can be stably obtained, the spasm feature information is evaluated from theperspective of muscle tension sensing, and quantitative evaluation of spasm is achieved; the spasm sensor is small in size and mass and brings convenience to clinical rehabilitation measurement.

Description

technical field [0001] The invention relates to the technical field of medical sensors for mechanical quantity detection, in particular to a spasm sensor based on muscle tension detection. Background technique [0002] Pathological spasticity is a specific movement disorder syndrome, which is manifested by intermittent or continuous muscle twitching accompanied by severe pain. The spasm can cause increased muscle tension, and clinically it is specifically manifested as muscle stiffness and rigidity Contraction, cramping, which impedes limb movement. [0003] The method of clinical evaluation of this type of spasticity mainly relies on the doctor to manually pull the patient's diseased limb, and observe the range of motion of the patient's joints and palpate to feel the resistance of the patient's muscles to achieve the purpose of evaluation, such as using the Ashowworth scale evaluation method. However, this method is a subjective measurement method, and different doctors w...

Problems solved by technology

However, this muscle tension meter has poor versatility, and it has not made an assessment for the evaluation level of spasticity.

[0007] For example, Chinese Patent No. CN105726039A discloses a limb spasm evaluation method and a device for realizing the method, through real-time monitoring of the elbow joint angular acceleration of the upper limb or the sudden change of the line velocity at any point of the forearm and the angle of the elbow joint or the line at any point of the forearm Acceleration change data is used to evaluate the degree of upper limb spasticity. It is characterized by simple structure and easy to wear, etc. It has certain limitations for quantitative analysis of spasticity.
