Abstract

The invention provides a system and method for measuring a joint bending degree. The system and method are used for solving the problem that joint bending degree measurement is poor in comfort experience and high in price and cannot achieve household application in the prior art, wherein the system comprises a joint bending degree measurement monitoring module and a data processing module, joint bending degree information is obtained through monitoring of the joint bending degree measurement monitoring module on the average joint curvature and sent to the data processing module, and the data processing module receives and processes the joint bending degree information, thereby achieving real-time monitoring on the joint bending degree. The system and method for measuring the joint bendingdegree have the advantages that a principle of a curvature sensor is applied, a joint bending signal is transmitted into a data processor through a curvature sensitive component to read a measured value, thereby measuring the joint bending degree in real time, knowing the joint motion situation, assisting a user in independently performing active recovery training of the motion function, reducingthe cost of joint monitoring equipment, improving the measurement accuracy and the equipment durability and improving the user comfort.

Description

technical field [0001] The invention belongs to the field of physiological parameter monitoring methods and equipment, and in particular relates to a joint curvature measurement system and measurement method. Background technique [0002] Human joint range of motion, also known as joint range of motion, is the arc of motion that joints pass through during motion. Joint range of motion is a common detection item in clinical rehabilitation medicine and disability identification. Doctors can guide patients to perform postoperative rehabilitation training by measuring joint range of motion, and monitor the patient's recovery at the same time. In order to achieve the ideal recovery effect, patients who have undergone joint surgery or patients with stroke and other diseases often need to carry out long-term active recovery training, in which joint bending and straightening training is very important for the recovery of joint motion function. The intensity is repeated and the dura...
