So many different types of focal dystonia!
Depending of the body part affected,
· Eye closure is called Blepharospasm (blepharo means eyelid in Greek).
· Jaw opening or clenching is called Oro-mandibular dystonia (oro means mouth and mandibular means jaw in Latin).
· Tongue protrusion is called Tongue dystonia
· Twisting of the head to one side is called Cervical dystonia (cervic means neck in Latin).
· Writing difficulty is called Writer’s cramp.
· Back arching, or trunk bending forward is called Axial dystonia (axial means axis as the spine).
· Walking or running difficulty is called the “ Crampe du marcheur” in France!
· Difficulty playing a musical instrument is called Musician’s cramp.
· Speaking difficulty is called Spasmodic dysphonia (phonia means the speech).
They usually start in adulthood and remain focal, without spreading to adjacent part of the body.
