Some apparatus and instrumentation have been developed for improving the relevance of dynamic test data obtained from human muscle specimens. In the first part of this paper the background is given and a special clamping and mounting arrangement is described which allows a small specimen to be made ready for test in less than a minute. The second part describes a new timing and sequencing instrument for regulating the electrical and mechanical stimulations applied to the specimen. The mechanical displacements are controlled by a type of servomechanism which can be driven from an f.m. tape recorder.
