How it can feel
- A foot, hand or limb stuck in a twisted or clenched position.
- Pain and fatigue in the muscles holding the posture.
- Difficulty walking or using the limb for ordinary tasks.
- Symptoms that may follow injury, casting, or a period of immobility.
Day to day
- Footwear, seating and transfers may need adaptation.
- Sleep can be wrecked by pain and position.
- Overlap with complex regional pain patterns is recognised for some people.
Understanding this FND symptom
In functional dystonia, motor control networks hold a posture programme that is hard to release. It is not the person “refusing” to straighten the limb.
What can help
- Specialist physiotherapy experienced with functional dystonia.
- Pain management support where pain is dominant.
- Gradual, guided movement rather than forced stretching alone.
- Addressing fear of movement after injury where that is part of the loop.

FAQs
Can dystonia be functional and still hurt this much?
Yes. Pain and posture problems often travel together. Severity does not decide whether a symptom is “real”.
