Electromyography Essay

Electromyography, also known as EMG, is an electro diagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. Electromyography is performed using an instrument called an electromyograph. An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, or recruitment order, or to analyze the biomechanics of human or animal movement.
In 1771, Galvani utilized electrical stimulation to demonstrate its effects on muscular tissue produces contraction and force. This electrical response was not quantified until the development of improved recording equipment, which included the cathode ray oscilloscope, by Gasser and Erlanger in 1922. Quantification of the amplifier and the oscillograph came later, and was done
These problems may include a herniated disc, amyotrophic lateral sclerosis (ALS), or myasthenia gravis. Electromyography is also useful in determining the cause of weakness, paralysis, or muscle pain that can only be resolved with movement. The issues associated with these sorts of diagnosis may stem from problems in a muscle, the nerves supplying a muscle, the spinal cord, or the areas of the brain that control these muscles. Biomechanically, Electromyography is utilized to measure certain factors, such as muscle fatigue and muscle activation, and forces associated with muscle movements. These measurements allow engineers to responsibly design workspaces and tasks that are safe for the laborer. Although Electromyography is heavily utilized in the medical arena to diagnose cause of symptoms, the purpose of this paper will be done from a Biomechanical perspective, and the applications of Electromyography to
