Deep tissue really has nothing to do with pressure. Instead, it refers to focused bodywork on a particular problem area. And that work is all about well, focus, and not force.
Elbow tendonitis? Doesn’t heal well if the therapist is using extremely deep pressure that causes a lot of pain. That no pain, no gain approach just signals the brain/nervous system to create even more guarding. Instead, if the work is intentional, focusing on slowly going into the next levels of tissue, the nervous system will allow and accept work at this already painful site. Most problems can begin to heal once the process of release has been introduced.
The modalities listed here are all “deep tissue” as soon as we focus on a specific problem area. Even lymphatic work with it’s ‘weight of a nickel’ pressure is deep tissue because we are working on a very deep system of the body. But, in any massage, you might prefer deeper or lighter pressure since preferences are individual and can be adjusted within the technique.
