This was recommended to me by my PT to work on thoracic vertebrae at home. I wish that the edges weren't so sharp, it's painful and it seems like it would still put pressure around the vertebrae if the edges were rounded. Because of this I don't use it as much as I should and don't get much benefit from it. The Theracane works better at massaging around the spine.
