Abstract
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 conductivity adhesive fills interstitial areas of the knit fabric and provides for adhering the electrode to the patient's skin.
