The TPN 300D is aTENS (Transcutaneus Electrical Nerve Stimulation) battery powered electrical unit which uses electrodes placed onto the skin over a painful area to deliver electrical impulses to the nerve fibers which lie underneath the skin surface. This   provides pain relief by blocking pain signals to the brain via the spinal cord and peripheral nervous system. TENS also stimulates production of the bodies own natural painkillers (endorphins). TENS can help reduce and control many common types of pain and is extremely effectively with few if any side effects.

The TPN 300D TENS machine has three main programmes (modes): continuous a constant tingling sensation, burst, a pulsing sensation in the underlying muscles, and modulation, a pleasant massage effect. The TPN 300 is the unit of choice, preferred by both clinicians and patients of the Barn Clinic Sheffield. Most patients have found the unit very effective, easy to use and good value for money; particularly as this unit is equiped with features normally found on expensive units features such as adjustable pulse frequency and duration.
