electromyogram

Electromyography is a muscle bioelectric pattern recorded by an electromyography device. The principle is to detect and record the weak electrical signals generated by muscles during contraction and relaxation. Electromyography is widely used to diagnose the health status of nerves and muscles, and is likened to a "miracle tool" that can make nerves and muscles "speak".

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Electromyography is a test that records the electrical activity of the nervous muscles and is the main means of examining the functional status of the peripheral nervous system. The main examination methods include nerve transmission examination and needle electrode electromyography examination, which record the electrical signals actively or induced by muscles and nerves. Skeletal muscles undergo potential changes during excitation due to the conduction and diffusion of action potentials in muscle fibers. The graph obtained by guiding and recording the potential changes that occur during skeletal muscle excitation using appropriate methods is called electromyography.
