Exercise, fibromyalgia, and fibrofog: a pilot study

Area of Science:

• Exercise Science
• Rheumatology
• Neuroscience

Background:

• Fibromyalgia syndrome (FMS) is a complex condition characterized by widespread pain, fatigue, and cognitive difficulties.
• Conventional treatments for FMS often yield suboptimal results for many patients.
• The impact of physical activity on cognitive function in FMS patients requires further investigation.

Purpose of the Study:

• To evaluate the efficacy of a structured physical activity program in improving psychological variables and FMS symptoms.
• To explore the effects of physical activity on perceived and objectively measured cognitive performance in FMS patients.

Main Methods:

• A pilot study involving 16 women diagnosed with FMS.
• Random assignment to an 18-week physical activity program or a control group.
• Assessment of psychological measures, FMS symptoms, cognitive function (perceived and objective), and walking capacity at baseline and posttest.

Main Results:

• Significant improvements were observed in the physical activity group for fatigue, depression, FMS symptoms, and self-reported cognitive symptoms.
• The physically active group demonstrated enhanced delayed recall performance compared to the control group.
• Beneficial effects of physical activity were noted across 6 out of 7 objective cognitive measures, with effect sizes ranging from small to large.

Conclusions:

• Physical activity demonstrates significant benefits for managing FMS symptoms, psychological distress, and cognitive impairments.
• Exercise interventions represent a valuable therapeutic option for FMS patients, particularly when conventional treatments are insufficient.
• Further research with larger cohorts is recommended to validate the observed cognitive improvements.
