Faradic current is a short duration interrupted direct current with a pulse duration ranging from 0.1 to 1 ms with a frequency of 50 to 100 Hz. Faradic current is surged to produce tetanic contraction and relaxation of the muscle. Treatment with faradic current also known as faradism.

Faradic is an interrupted direct current that has a frequency of 50:100Hz with a pulse duration from 0.1-1MS. This frequency and duration cause contraction and relaxation in innervated (nerves intact) muscles. It does not work on muscles that are denervated muscle; to cause the same effect a short pulse duration would be required. When applying faradic stimulation, the stimulation of the sensory nerve can result in the patient experiencing a pricking sensation due to the short duration of the pulse. The stimulated nerve causes a reaction in the motor fibres which makes the muscle contract.
