A
Feedback:
TENS is a pain management technique that delivers bursts of electricity to the skin and underlying nerves. It is safe for managing acute and chronic pain and does not produce systemic side effects or addiction. The electricity is delivered from a battery-operated TENS unit through electrode patches that are placed at appropriate sites, such as directly over the affected are, at areas along a nerve pathway, or at points distal to the painful area. Cold compresses cause decrease in vasodilation. Warm compresses cause heat to the skin and subcutaneous tissues. A cordotomy interrupts the pain pathways in the spinal cord.
