Limb spasticity evaluating and testing method and device for achieving method

Abstract

The invention discloses a limb spasticity evaluating and testing method and a device for achieving the method. The limb spasticity evaluating and testing method comprises the following steps: measuring change data of elbow joint angle acceleration or linear acceleration of any point of a front arm in the process that an elbow joint of a human body stretches at different angle speeds, and joint angle values corresponding to the acceleration change, processing measured angles, speeds and acceleration signals, displaying in real time, and storing; and evaluating the upper limb spasticity degree according to elbow joint angle acceleration of upper and lower limbs at different angle speeds or elbow joint angles corresponding to sudden linear speed change of any point of the front arm and elbow joint angle acceleration or acceleration change data of any point of the front arm. Spasticity can be objectively and quantitatively tested and evaluated, the difficulty that current spasticity testing is relatively large in objectiveness can be solved, and the method is simple in design and low in cost.

Description

Technical field: [0001] The invention relates to a limb spasm evaluation method and a device for realizing the method. Background technique: [0002] Spasticity is a movement disorder caused by hyperexcitability of the stretch reflex and characterized by a speed-dependent, increased tonic stretch reflex with hyperactive tendon reflexes. The treatment of spasticity is inseparable from the assessment of spasticity, and there are subjective assessment methods and objective assessment methods for spasticity detection. At present, the most widely used subjective assessment scale in clinical practice is the modified Ashworth scale, which is easy to implement clinically, but the scale itself is a qualitative description, and the evaluation is highly subjective, which cannot meet the requirements of objective and accurate quantitative assessment. Although large-scale isokinetic muscle strength testing systems, electromyography and other equipment can meet the requirements of object...

Problems solved by technology

At present, the most widely used subjective assessment scale in clinical practice is the modified Ashworth scale, which is easy to implement clinically, but the scale itself is a qualitative description, and the evaluation is highly subjective, which cannot meet the requirements of objective and accurate quantitative assessment.

Although the large-scale isokinetic muscle strength testing system, electromyography and other equipment can meet the requirements of objective quantitative evaluation, they have not been able to be clinically popularized due to the limitations of factors such as high price and complicated operation.
