Muscle Fatigue in Fibromyalgia Originates in the Brain

By Adrienne Dellwo
December 16, 2013

Research Brief

Research published in Annals of the Rheumatic Diseases suggests that what people with fibromyalgia perceive as muscle fatigue is actually our brains misinterpreting signals – just as it does with signals from pain and other sensory stimuli.

By comparing objective markers of muscle fatigue after exercising a muscle to perceived exhaustion, researchers were able to determine that participants with fibromyalgia didn't have true muscle fatigue compared to healthy controls. Instead, the perceived fatigue appeared to be part of our central nervous system dysfunction.

The study also supported earlier research with findings of:

  • Shorter endurance times,
  • Lower strength
  • Perceptions of higher effort.

Researchers say their result is possibly due to difficulty differentiating pain from muscle fatigue, which also has been seen in earlier studies. They say their results may help explain our intolerance of physical activity. It could also explain why we generally see small improvements to muscle fitness when we're exercising to the point of perceived exhaustion.
