Percutaneous electrical nerve stimulation (PENS) combines advantages of electroacupuncture and TENS. Rather than using surface electrodes, PENS uses acupuncturelike needle probes as electrodes, with these placed at dermatomal levels corresponding to local pathology. The main advantage of PENS over TENS is that it bypasses local skin resistance and delivers electrical stimuli at the precisely desired level in close proximity to the nerve endings located in soft tissue, muscle, or periosteum.
