I have a client with early onset osteoarthritis and has had several operations – (wrists, neck, foot). She now has degeneration in her right hip but does not want surgery any time soon. Would use of the foam roller on all of the areas around the hip be beneficial and advised in your opinion (if client can stand it?)
Using a foam roller for self myofascial release can be great for almost anybody. But you should look into contraincidations for the use of foam rollers before having the client use one. Issues like veracose veins would be a one such reason not use the foam roller. But I would get clearance from the client’s doctor just to make sure.
As for teaching the client to use the roller, that is something that requires very solid knowledge of the proper use of a roller (or tennis ball, baseball, golf ball, etc.
as a MELT instructor, I use soft foam rollers on all my clients and I teach classes with participants that have probably conditions like the one you describe. It is okay and indeed very beneficial.
Having said that, I would suggest that you acquaint yourself with the MELT technique. The soft roller and the length technique are very different from the white or black hard rollers that are still commonly used,
