I believe there can be more to trigger point therapy than just muscle tension relief, however that is all I use it for. It has been my exerience that I get the same amount or better relief using the foam roller. Not only is it a lot cheaper, but can be done whenever needed in the comfort of my living room. :lol:
It takes a bit of practice to do it right, and like I said, it can be somewhat painful on the tight spots, but it really works. Again, follow the instructions and don't over do it.
These prices are quite reasonable.
