TENS is a form of Electrotherapy. It is commonly used at Total Physio. It refers to the diffusion of small electrical pulses through the skin to the underlying peripheral nerves. Pain can be managed through selectively stimulating large nerve fibres by altering the pulse amplitude and scope.
TENS refers to to the transmission of small electrical pulses through the skin to the underlying peripheral nerves. The basic principle behind conventional or high frequency TENS is that large nerve fibres can be selectively stimulated by adjusting the pulse amplitude, pulse width and repetition rate of specially selected wave forms. These large fibres have a lower threshold for stimulation and faster conduction velocity than the small fibres that conduct pain messages.
