Myograph
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 and the wire myograph ; for skeletal muscle other devices such as the acceleromyograph can be used.
In pharmacology, myographs are used to record muscle contraction in organ bath preparations.
The related technique of electromyography is used to measure electrical activity of the muscle instead of force.
