Chapters on the physiological basis of excitable tissues and principles of electrical stimulation contain excellent graphs and figures that aid readers in descriptions of physiological concepts (ie, action potentials, strength-duration relationships, rheobase and chronaxie, and length-tension relationships) as well as stimulation principles, such as impedance, Ohm's Law, and stimulation parameters.
The TECA CH3 chronaxie meter* was used to determine cutaneous pain threshold.
We determined experimental pain threshold with a TECA CH3 chronaxie meter,(*) which produces a measurable low voltage direct current.
