The difference between Swedish massage and deep tissue massage, is Swedish massage is actually the base for deep tissue massage and deep tissue massage is delivered on a much deeper level. Swedish massage has some basic strokes, like effleurage and petrissage. With deep-tissue massage, you actually take those same modalities, and take them to a deeper level.
You can actually use other tools, instead of using just your hands, you can use your elbow. You can use your forearms. Things that will deliver a deeper amount of pressure, rather than just Swedish massage, which typically you would apply with your hands and your fingers. Many times when people request a Swedish massage, what they're asking for they often request a relaxation massage or something of this kind.
It's pretty much interchangeable. So Swedish massage is very relaxing. Deep tissue massage can also be very relaxing, I find if it's delivered by an expert that knows where that pain threshold is for you. Deep tissue massage, every once in a while someone will ask for deep pressure massage or harder pressure massage, or something like that, so that's what they're referring to.
