What is the name of the procedure that measures and records the strength of a muscle contraction?

The procedure that measures and records the strength of a muscle contraction is known as electromyography. This technique involves the use of electrodes to detect the electrical activity of muscles, which can indicate how effectively they are functioning. When a muscle contracts, it generates electrical signals that can be captured and analyzed. Electromyography is commonly used in the diagnosis of neuromuscular disorders, as it provides essential data on muscle health and nerve function.

In contrast, myography generally refers to the recording of muscle activity but is a broader term and may not be as specifically focused on quantifying strength in the same way. Neurometry pertains to the measurement of nerve functions rather than muscle contractions directly. Fasciography involves imaging the fascia and is not concerned with muscle contraction strength. Thus, electromyography stands out as the most precise term for the procedure focused on measuring muscle contraction strength.
