What This Means
This research suggests that people with fibromyalgia who take the medication duloxetine may get extra benefits from also doing a structured postural exercise program at home. In this study, 51 fibromyalgia patients were divided into two groups: one group took duloxetine only, and the other group took duloxetine and also completed a series of postural exercises three times per week for four weeks. Both groups improved over time in pain, mood, sleep, and quality of life — likely because of the medication — but the exercise group showed meaningfully greater improvements specifically in sleep quality, physical quality of life, and the ability to bend and move the trunk/spine.
The differences between groups were statistically significant and, in the case of spinal mobility, showed very large effect sizes. However, the exercise program did not provide extra benefit over medication alone for pain levels, anxiety, depression, mental well-being, or pain sensitivity at specific pressure points. This suggests that postural exercise may target certain aspects of fibromyalgia — particularly physical functioning and sleep — more effectively than others when combined with drug treatment.
This research suggests that a relatively simple, home-based exercise routine could be a worthwhile addition to standard medication treatment for fibromyalgia, particularly for improving sleep and physical mobility. However, the study was short (only four weeks) and did not track patients after the program ended, so it is unclear whether these benefits last. Larger and longer studies with follow-up assessments are needed before firm conclusions can be drawn.
