Back issues -- try this...
Both my husband and I have occasional muscle spasms.  My daughter-in-law showed us hers when we were visiting the grandkids.  It works like a dream.  It allows you to isolate the muscle and apply the pressure YOU want with immediate relief.  This is a must have if you are a couch potato or an exercise junky.  Great for a person alone, when you need some pressure on those hard to reach back muscles.
