"Percutaneous Electrical Nerve Stimulation" - See Types of Electrotherapy.

Percutaneous electrical nerve stimulation. An enhanced and newer type of pain management therapy that makes use of very thin needles (much like those in acupuncture) that are inserted in the lower back by the chiropractor. Small, battery-powered TENS units also are available for use at home, work, or other activities. The patient is able to control the level and frequency of stimulation, and self-administer impulses during episodes of pain.

Pens is a card game for two or more players. The players sit around a table, and a number of pens (one less than the number of players) are laid with equal spacing in the centre of the table, at an equal distance from each of the players. Cards are then removed from the pack such that only one group of four of a kind per player remains.

Technical drawing pens produce a sharp line that never varies in width. They come in a range of colors, and widths which create different effects.
