Thai Massage differs from western massage in its approach. In the West massage is highly regulated, and a lot of emphasis is placed on anatomy and physiology, scientific studies, observable effects on the body, research, and clinical data.
In the East, Thai Massage is based on an energy model like most Asian therapeutic systems. There is little interest in clinical data or documented research regarding its effects. If people like how it feels and if it helps them, that’s good enough for them.
