Described below is one of the many approaches I've tried or considered trying for healing my chronic myofascial pain:
BOTTOM LINE: Haven't tried extensively, but potentially helpful.
The Feldenkrais Method, as described in Wikipedia, is a movement-based approach where a practitioner directs attention to a person's inefficient or strained habitual movement patterns and teaches them new patterns using gentle, slow, repeated movements. It is used to improve movement patterns because habitual and repetitive movement patterns can contribute towards and in some cases cause injury, pain, and physical dysfunction.
I attended two Feldenkrais classes when I was still in a great deal of pain and hadn't recognized my contributing traumas (described in My Healing Journey). The Feldenkrais classes didn't relieve my pain (granted, I admit I didn't keep up with the program), and they saddened me at the time because they reminded me that this former gymnast's body could no longer move without pain.
The Alexander Technique, according to the "Complete Guide to the Alexander Technique" website, is a way of learning how you can get rid of harmful tension in your body by helping you identify inefficient habits of movement and patterns of accumulated tension, which interfere with our innate ability to move easily. It offers the opportunity to learn to move mindfully through life and take charge of one’s own learning and healing process. I have not tried any classes using the Alexander Technique.
In general, I think subtle, moderate, and efficient movement is good, but I'm not sure these techniques alone would heal highly emotion- or trauma-fed chronic pain like mine. They could likely help those of us in this category manage our pain, similar to activities such as good posture and ergonomics. I suspect movement practices could be helpful in eliminating chronic pain when coupled with other approaches like JFB-MFR, talk therapy, tapping, Somatic Experiencing (SE™), and/or eye movement desensitization and reprocessing (EMDR).
