The University of South Florida has just shown us that the application of HBOT caused significant pain relief in just 20 treatments. In addition, range of motion was also significantly improved; the difference being that 20 to 30 sessions were needed to obtain this positive response.

More importantly, the 7 year follow up revealed that all patients remained substantially pain and none required hip arthroplasty <view study>
