Drugs, such as antidepressants, antiepileptics, and opioids, are often not effective for patients with fibromyalgia. In addition, these pharmacologic options frequently have side effects. Alternatives, such as psychotherapy, require professionals with special training, and exercise necessitates motivation.

What possibilities are left for fibromyalgia patients saddled with chronic, widespread pain, and problems with mood, sleep, and cognition?

At the June 2017 Sleep meeting in Boston, researchers presented a tentative possibility. A small study of ten adults with fibromyalgia took part in a fifteen-day experiment. First, the subjects slept at home for a week. Then they had an overnight session where different measures, such as their pain sensitivity, and melatonin secretion, were assessed.

Half the subjects used the light box in the morning, and half used it at night.

 

After that, subjects were asked to use a light box for an hour a day for six days. The subjects were randomly assigned so half them used the light box in the morning, and half in the evening, for the next six days.

Both groups improved in terms of function and pain sensitivity, and reported no side effects. Importantly, the morning light treatment group led to a clinically meaningful improvement in function, as measured by the Fibromyalgia Impact Questionnaire (FIQ) and heat pain threshold.

How significant are these changes? Helen J. Burgess, PhD, and her colleagues concluded, “Morning bright light should be further explored as a potentially feasible, acceptable and effective adjunctive treatment for fibromyalgia. The improvement in function was similar to that seen after psychotherapy, and about half of the improvement seen after months of exercise training.”
