| Simply put, the
Interpolated Twitch Technique is an index to measure the level of completeness
of muscle activation.
THE INTERPOLATED TWITCH
TECHNIQUE was first described in 1928 by Denny-Brown, and it
is frequently used to study the degree of motor unit activation
during voluntary effort. During contraction, an electrical stimulus
(typically a single or doublet twitch) is superimposed onto a muscle
or its nerve, and the evoked interpolated twitch torque (ITT) or
superimposed twitch force is measured. The ITT is a measure of
the number of motor units that are not maximally recruited during
voluntary contraction. Therefore, the ITT is an index of the
level of completeness of muscle activation.
