Electromyography (EMG) is a signal that conveys the health of the muscles and the nerves that control the muscles. There are two methods used to record the muscle reading of an individual using EMG 1.Using thin needle electrode pierced through the skin to take the reading and 2.Using surface electrodes which are attached to the surface of the skin. The surface electrodes are placed directly over the nerve endings inside the skin and the readings in terms of voltage fluctuations are observed on the connected system. In this work, a method to identify the wrist movement and elbow movement of the body using the data acquired through the surface electrodes connected to the body and then use the patterns obtained to formulate a method to identify the fatigue level in the respective muscles is presented.

Keywords: Surface electrodes, fatigue level, MUAP, Mean, RMS, DAMV.
