Embodiment Construction

[0022] Surface electromyography (sEMG), also known as dynamic electromyography, is a relatively new instrument for clinical examination, evaluation, research, and treatment. Common clinical nerve-muscle dysfunction and bone-muscle dysfunction can be diagnosed and treated with surface electromyography. The origin of surface electromyography can be traced back to the mid-17th century, when Francesco discovered that a special muscle was the source of energy for the electric-finned stickleback. In 1773, Walsh discovered that the contraction of eel muscles could generate electric sparks. But it wasn't until the 1790s that Galvani demonstrated the relationship between muscle contraction and electrical activity. The galvanometer was invented in the early 1800s. In 1849, DuBois-Reymond first confirmed the existence of electrical activity in the active contraction of muscles. With the rapid development of needle electromyography in the 1930s and 1950s, surface electromyography appear...

Abstract

The invention discloses a parameter acquisition evaluating system of upper limb movement, comprising a motion tracking device, a data acquisition circuit and a comprehensive processing device, wherein the motion tracking device and the data acquisition circuit are connected with a tested person and output motion parameters obtained from the tested person to the comprehensive processing device; the comprehensive processing device is respectively connected with the motion tracking device and the data acquisition circuit. The invention also discloses an acquisition evaluating method using the system, and the method comprises the following steps that the motion locus, the motion speed, the motion accelerated speed, the joint range of motion of upper limbs of the tested person are recorded in time by an infrared camera in the motion tracking device; the electromyographic signal change of the forearm muscle is collected by measuring electrodes and a myoelectricity amplified filter circuit; the opposite pinch strength magnitude of a thumb and an index finger is collected through a thin film pressure sensor; the recorded motion paramours are transmitted to the comprehensive processing device for analysis and processing; an average person norm is established; the measuring values of the tested person are compared with the average person norm, and the deviation of the upper limb motion of a patient is judged.

Description

technical field [0001] The invention relates to data collection technology, in particular to a device and method for collecting and evaluating upper limb motion parameters. Background technique [0002] Upper limb movement is a complex three-dimensional activity involving upper limb bones, muscles, shoulders, elbows, wrists, hands and other joints. Its mobility directly affects the activities of daily lives (ADL) of patients. Through the analysis of the characteristics of the upper limb movement, it is possible to understand the individual's functional situation, evaluate the functional loss of the upper limb, and provide hints for training the corresponding muscle groups and correcting the upper limb movement. The thin-film pressure sensor is tightly attached to the surface of the object to measure the interaction force between the hand and the object. There are two types of motor function assessment scales commonly used by therapists at home and abroad, one is the Fugl-Me...
