Hi Goldrush

It looks like the brace is based on the principle of applying a counter-pressure to reduce pressure on the muscle/tendon origin. Probably most commonly seen in people who have been diagnosed with Wikipedia reference-linktennis elbow. There's actually a taping technique that I use that applies this principle for people with Wikipedia reference-linkplantar fasciitis and my patients usually report some relief.

I would think this brace would be helpful along with a physio treatment plan aimed at reducing the cause of the problem.
