Bob,

    TENS units are Transcutaneous Nerve Stimulators... they are used for 
painful conditions resulting from injury to muscles or nerves.  They are 
marginally effective... sometimes they work like a charm but other times they 
don't work that well.   They work best when the body is intact... a torn muscle 
or nerve will not respond as well as an intact one.
