An instrument for detecting dystonia

Abstract

The invention relates to a myodystony detector. The myodystony detector comprises a holding frame, a damping part and a detecting system, wherein the holding frame is held and rapidly squeezed and clamped by a tested person so that the muscular tension of the hand is detected, the holding frame comprises a fixed rod and a swing rod, and the swing rod can rotate or translate relative to the fixed rod; the damping part comprises a spring capable of applying action force to the swing rod; the detecting system comprises a displacement detection device for capturing the relative displacement information of the swing rod directly or indirectly through a bar-shaped body connected to the swing rod, and converting the relative displacement information into signals which are output, a data processing system used for collecting, recording and storing the signals output by the displacement detection device, and a data analyzing system for processing the signals into the amplitude and speed for squeezing and clamping the holding frame of the tested person, wherein the muscular tension condition of the tested person is judged according to the squeezing and clamping amplitude and speed output by the data analyzing system. The holding frame is rapidly squeezed and clamped and released, the relative displacement information of the swing rod is captured in real time, the amplitude and speed in squeezing and clamping the holding frame of the tested person are tested, and thus the muscular tension condition of the tested person is detected.

Description

technical field [0001] The invention relates to a medical device, in particular to a dystonia detector. Background technique [0002] As for the state of muscle tension, the traditional method mainly relies on stretching the patient's affected limb, observing the range of motion of the patient's joints and feeling the resistance of the patient's muscles. This method has many subjective components, which affects the accuracy of judgment; With the advancement of technology, there have been equipment and methods for detecting muscle tension, such as "a muscle tension measuring instrument" (notification number CN 203776916 U), "an upper limb muscle tension measuring device" (publication number CN 104622484 A ), "A Muscle Tension Detection Equipment and System" (Notice No. CN 204147049 U), "Muscle Tension Detection and Analysis Equipment and Detection Method" (Publication No. CN1077026A), "Foot Muscle Tension Quantitative Detector" (Notice No. CN 201710367 U) and other detection...
