Gentle did not lose to deep, for chronic back pain.
In the largest trial of its kind, 401 people with chronic low back pain received relaxation massage, which is the Swedish vocabulary, or structural massage, or usual care. At ten weeks both massage groups had improved about equally, 2.9 and 2.5 points better than usual care on the standard disability scale, and the benefit lasted at least six months. The authors found no clinically meaningful difference between the two kinds of massage. Gentle is not the same as less.
