An innovative device for instant measurement of Surface Electro-Myography for clinical use

Surface Electro-Myography (SEMG) signal plays key roles for clinical measurement. The strength of this signal at different instant of time and at different places of our body shows the respective muscle strength and identify if any types of muscles fatigue occurs or not. This is useful for sports personnel’s and especially for amputees and different orthopedic patients. The surgeon should have a vivid knowledge about the muscle strength of any part of human body. So a portable hand carrying device is necessary. In this paper we want to illustrate a proposed system which can indicate the strength as well as display the RMS value of the collected Electro-Myography signal on a proposed trainer board consists of a LED bar which indicates the respective strength of the signal in volts. The following system has also a provision to display the strength pattern in a PC in Lab View environment. This shows a detailed analysis of the EMG signal in respect to its waveform, equivalent DC value etc.

► Surface Electro-Myography signal strength is measured using this device.
► Signal is acquired using electrodes and processed by signal processing circuitry.
► Strength is measured using bar graph display driver.
► Graphic User Interface is used for a visual display of the signal patterns.
