chronaxie
[kro´nak-se]the minimum time at which an electric current must flow at a voltage twice the rheobase to cause a muscle to contract. In a strength-duration curve for muscle stimulation, it is the pulse width at a voltage twice that at the rheobase.
chro·nax·ie
(krō'nak-sē),A measurement of excitability of nervous or muscular tissue; the shortest duration of an effective electrical stimulus having a strength equal to twice the minimum strength required for excitation.

(krō′năk′sē, krŏn′ăk′-)n. pl. chronax·ies
The minimum interval of time necessary to electrically stimulate a muscle or nerve fiber, using twice the minimum current needed to elicit a threshold response.

chronaxie
The minimum time for which an adequate electric current must be applied to a nerve to produce a contraction of the associated muscle. An adequate current is one that is at least twice the threshold value.chronaxie, chronaxy
the minimum time at which an electric current must flow at a voltage twice the rheobase to cause a muscle to contract.
