Detect Electromyograph Signals on Grasping Handgrip Movement

Abstract

EMG signals are used to assist doctors in the diagnosis of a patient's muscle condition. The presence of anomalies in the EMG signal recording results indicate an abnormality in the patient's body muscle.In general, information obtained from EMG signals can be used to determine the time of muscle activation, to estimate the strength produced by muscles and to obtain index of muscle fatigue level through the analysis of frequency spectrum of EMG signal (Electromyography) is the result of measurement of electric current on the body or called by biolyte produced by muscle fibers when contractions occur as a result of neuromuscular activity.Excessive muscle activity in EMG (Electromyography) can cause pain and even pain in the arms can sometimes arise without any obvious cause, other than by accident or sudden injury. Sudden pain on one or both sides of the arm may confuse the person who is experiencing it, but there are various conditions that can cause it and most involve muscles.From the results of the MPF then When doing the movement of the palm of the hand muscle flexor carpi radialis has a mean frequency power value is always greater than the muscle extensor carpi Ulnaris for all respondents are not distinguished men and women of various ages.
