A force-gauge implement recording the isometric contraction of one fibre from a whole muscle under different stretches.
A counterbalancing mechanism has been devised for use with highly sensitive semiconductor force gauges. This device is destined to balance any constant stress, especially if it over-passes the normal range of use of the gauge, leaving the instrument able to record accurately weak transient force variations superimposed on an initial value. It has been designed and used initially to record isometric contractions of striated fibres, selected from whole muscles by microelectrode stimulation.
