A rare club

Article Abstract:

Dystonia is a form of spasticity. Muscles in the trunk or limbs undergo sustained contraction causing repeated movement, twisting or unusual posture. Initial symptoms include tremor, cramp in the foot, and speech problems. The dystonia may affect the whole body, one part of it, or a number of body parts, with some patterns being identifiable as known syndromes. Idiopathic generalized dystonia is a very rare condition. Treatment includes surgery on the thalamus, and the use of drugs which act on the central nervous system.
