There is some good information about Fibromyalgia in Ruth Werners Massage Therapists Guide to Pathology which just came out in a 2nd edition by the way. The treatment suggestions are rather general, but the main point is that the neuromuscular system and its sensory component especially is not functioning normally, so pain perception is heightened. The system is hypersensitive, so it is easy to "over treat". A typical relaxation massage routine could be too much stimulation and lead to increased pain. On the other hand, done with that caution, massage to relieve stress can be enormously helpful, as it can, as mentioned before, have positive effects on the neurotransmitters that modulate the pain response. It is also speculated that the underlying problem leading to this imbalance is actually a sleep disorder. Chronic lack of proper sleep can drastically effect the neurotransmitter balance. However is the sleep disturbance a cause of, or a result of, the chronic pain....still unknown! If massage can help the client get better sleep, it would help in any case. Following is an abstract from the database on the Touch Research Institutes website. A good place to visit.Field, T., Diego, M., Cullen, C., Hernandez-Reif, M., & Sunshine, W. (2002). Fibromyalgia pain and substance P decreases and sleep improves following massage therapy. Journal of Clinical Rheumatology.METHOD: To determine the effects of massage therapy versus relaxation therapy on sleep, substance P and pain in fibromyalgia patients, twenty four adult fibromyalgia patients were randomly assigned to a massage therapy or relaxation therapy group. They received 30-minute treatments twice a week for five weeks. RESULTS: Both groups showed a decrease in anxiety and depressed mood immediately after the first and last therapy sessions. However, across the course of the study only the massage therapy group reviewed an increase in the number of sleep hours and a decrease in their sleep movements.However, In addition, substance P levels decreased and the patients' physicians assigned lower disease and pain ratings and rated fewer tenderpoints in the massage therapy group.
