Fear of Movement in Teens With Fibromyalgia: What Predicts Recovery

Fear of Movement in Teens With Fibromyalgia: What Predicts Recovery

Fibromyalgia also affects teenagers. A new analysis asks which changes during treatment predict how well a teen functions a year later. The answer: becoming less afraid of movement. The study appeared in The Journal of Pain on October 24, 2026.

The Study

Researchers at Cincinnati Children's Hospital Medical Center analysed data from the FIT Teens trial, a multi-centre randomised trial. It included 317 adolescents with juvenile fibromyalgia. They received one of three treatments:

• Cognitive behavioural therapy (CBT)
• Graded aerobic exercise
• CBT combined with neuromuscular exercise training

In the original trial, daily functioning improved in all three groups and stayed better for a year. This new analysis asked a follow-up question: which changes in the first three months predicted functioning later? The researchers looked at two factors:

• Fear of movement: worry that activity will cause pain or harm
• Pain catastrophising: a tendency to expect the worst when in pain

The Results

• A drop in both fear of movement and pain catastrophising during the first three months predicted better functioning at 3 months.
• At 12 months, only the drop in fear of movement still predicted better functioning.

The authors conclude that treatments for teens with fibromyalgia should prioritise ways to reduce fear of movement.

Limits of the Study

• This is a secondary analysis of an existing trial. It shows links, not proof of cause.
• Because the analysis pooled all three treatments, it does not show which treatment lowers fear of movement best.
• The results apply to teenagers in a trial setting. They may not apply to adults.

What This Means for You

If you are a parent or a teen: gentle, guided movement helps, and feeling safe to move seems to matter as much as the movement itself. A therapist can help your teen build confidence step by step, for example through a paediatric physiotherapist or a psychologist who knows chronic pain. If your teen avoids activity out of fear of pain, raise this with the care team. It is a treatable part of the problem.
