What is "myograph"

Myograph \My"o*graph\, n. [Myo- + -graph.] (Physiol.) An instrument for determining and recording the different phases, as the intensity, velocity, etc., of a muscular contraction.

n. (context physiology English) An instrument for determining and recording the intensity, velocity, etc., of a muscular contraction.

A myograph is any device used to measure the force produced by a muscle when under contraction. Such a device is commonly used in myography, the study of the velocity and intensity of muscular contraction.

A myograph can take several forms: for tubular structures such as blood vessels these include the pressure myograph (where a segment of a blood vessel is cannulated at either or both ends) and the wire myograph (where the blood vessel segment is threaded onto a pair of pins or wires); for skeletal muscle other devices such as the acceleromyograph can be used.
