Strength Training Versus Walking on the Fibromyalgia Impact: A Blinded Randomised Controlled Trial

Area of Science:

• Musculoskeletal Disorders
• Rehabilitation Medicine
• Pain Management

Background:

• Fibromyalgia is a chronic condition characterized by widespread pain and fatigue.
• Current treatment options for fibromyalgia have varying efficacy.
• Objective assessment of exercise interventions is crucial for understanding their impact on fibromyalgia.

Purpose of the Study:

• To compare the effectiveness of 24 sessions of progressive intensity strength training against constant intensity and walking exercises for fibromyalgia.
• To evaluate the impact of these exercise regimens on secondary outcomes including sleep, anxiety, depression, pain mechanisms, and physical function.

Main Methods:

• A blinded, randomized controlled trial involving 66 participants with fibromyalgia.
• Participants were allocated to progressive strength training, constant intensity strength training, or walking exercise groups.
• Exercise interventions consisted of 24 sessions over three months, with subsequent follow-up.

Main Results:

• No significant differences were found in the primary outcome (fibromyalgia impact) between the three groups at any time point.
• Within-group analyses indicated symptom reduction across all exercise types, but minimal clinically important differences were not achieved.
• While participants reported perceived improvement, treatment adherence was low across all groups.

Conclusions:

• Progressive intensity strength training did not offer superior benefits for fibromyalgia impact compared to constant intensity or walking exercises.
• All tested exercise modalities demonstrated some positive effects on fibromyalgia symptoms, though not clinically significant.
• Further research is needed to optimize exercise protocols and improve adherence for fibromyalgia management.
