The stiff muscles (myotonia congenita) present in one of the patient's leg explains the difference between EMG recorded from the right and left leg.

An EMG is an abbreviation for electromyography and it can be defined as a diagnostic test or procedure that is typically used to measure, assess and evaluate the health condition of muscles and the nerve cells (motor neurons) within the body of a living organism that controls them.

Based on the electromyography (EMG) test report, a pathological condition which explains the difference between EMG recorded from the right and left leg is as a result of the stiff muscles (myotonia congenita) present in one of the patient's leg.

In conclusion, electromyography (EMG) is primarily used to measure a burst of electrical activity across muscle membranes when they contract.

Four graphs A, B, C and D. Each graph is a line that occupies a square. The left and right sides of the graph touch the x axis. Each graph has a different shape, but the space under the line remains the same. Graph A. Solid line symmetrical bell-shaped curve. Graph B. Dotted line symmetrical bell-shaped curve superimposed on a solid asymmetrical curve that leans to the right of the dotted curve. Graph C. Dotted line symmetrical bell-shaped curve superimposed on a solid curve. The solid curve is symmetrical. It goes up on both ends to form two humps and it is lower in the middle. The solid curve looks like the letter M. Graph D. Dotted line symmetrical bell-shaped curve superimposed on a symmetrical curve that is narrower and taller than the dotted line curve.
