Exercise and its effects on perceived symptoms and physical function in adults with fibromyalgia: results from a randomized trial

Adults with fibromyalgia (FM) have been shown to benefit from exercise and its therapeutic effects on their condition. However, FM symptoms often limit the ability to exercise and create obstacles that discourage an active lifestyle and physical activity.


One study evaluated the effects of accumulating at least 30 minutes of self-selected lifestyle physical activity (LPA) on perceived physical function, pain, fatigue, body mass index, depression, tenderness, and the six-minute walk test in adults with FM.

Eighty-four minimally active adults with FM were randomized to either LPA or a FM education control (FME) group. Participants in the LPA group worked toward accumulating 30 minutes of self-selected moderate-intensity LPA, 5–7 days per week, while the FME participants received only information and support.

Of the 84 participants, 73 (87%) completed the 12-week trial. The LPA group increased their average daily steps by 54%. As well, the LPA group reported significantly less perceived functional deficits (P = 0.032) and less pain (P = 0.006) compared to the FME group. No differences between the groups were seen on the six-minute walk test (P = 0.067), fatigue, depression, body mass index, or tenderness.

This study demonstrated that accumulating as little as 30 minutes of LPA throughout the day can produce clinically relevant changes in how previously minimally active adults with FM perceive physical function and pain.
