I don’t know if it’s recommended per se, but I’ve found that it helps with the muscle knots, or trigger points, that I develop constantly. I bought a hand-held one from Amazon on the advice of my physical therapist. I’ve been so pleased with the results that I just ordered a wrap style. The knots always return, but I can reduce the pain in between PT and dry needling sessions.
This is one item where price matters. You want the more expensive product, not the $40 one. Read the product descriptions or ask a PT for recommendations.
