1. A flexible transcutaneous electrical nerve and/or muscle stimulation electrode comprising:
- a conductive fabric comprising knit conductive fiber means for enabling the conductive fabric to be stretched up to at least about 20 percent greater than the original conductive fabric dimension in the direction of stretch, said knit conductive fiber means comprising an array of interknit conductive fibers with interstitial areas therebetween;
flexible solid conductive adhesive means disposed within said interstitial areas and on one side of said conductive fabric for adhering the flexible transcutaneous electrical nerve and/or muscle stimulation electrode to the skin of a patient and providing an electrical conducting contact therebetween;
electrical lead wire means interconnected with said conductive fabric and adapted for interconnection with an electrical stimulation device for providing electrical signals to said conductive fabric; and
non-conductive sheet means disposed on another side of said conductive fabric for preventing undesired electrical contact with the conductive fabric.

Abstract
A transcutaneous nerve and/or muscle stimulation electrode is provided which may be contoured to the skin areas of a patient and stretched therewith while impulse signals are electrically conducted into the body. This stretching ability is provided by a knit conductive fabric which is stretchable up to at least about 20% greater than the original conductive fabric dimension in a direction of stretch without loss of conductivity. A conductive adhesive fills interstitial areas of the knit fabric and provides for adhering the electrode to the patient'"'"'s skin.
