• muscles
  • Dystonia is a response to simultaneous contraction of agonist and antagonist muscles seen as twisting and contorting that affect posture and stance. (wikipedia.org)
  • The muscles most often affected are usually in the legs and feet (75% of reported cases), but the upper body muscles such as the arms, face, neck, and trunk have also been observed to be affected during the episodes of dystonia. (wikipedia.org)
  • However, in dystonia both muscles in the pair contract at the same time leading to the abnormal movement or posture. (netdoctor.co.uk)
  • Dystonia can affect just one muscle, a group of muscles or all of your muscles. (medlineplus.gov)
  • Cervical dystonia exercises help strengthen and stretch your muscles. (livestrong.com)
  • Myoclonus-dystonia is a genetically heterogeneous disorder characterized by myoclonic jerks affecting mostly proximal muscles. (nih.gov)
  • hereditary
  • Dystonia can be classified according to the age of onset (childhood, adolescent or adult) by body distribution (focal, multifocal, segmental, generalised or hemidystonia) or by the cause (primary, secondary, 'dystonia plus' syndromes or combinations of hereditary and degenerative causes). (netdoctor.co.uk)
  • In general, focal dystonias are classified as primary (idiopathic) and are not hereditary. (aans.org)
  • onset
  • However, it is unknown if the gene that causes Early Onset Torsion Dystonia is responsible for the other dystonias as well. (wikipedia.org)
  • The chance that dystonia will affect multiple body parts is generally linked to the age of onset. (aans.org)
  • However, there are specific primary dystonias with childhood or adolescent onset that have been linked to genetic mutations. (aans.org)
  • The majority of early-onset primary dystonias, which may appear during childhood or early adulthood, are due to mutations of a gene known as DYT1. (aans.org)
  • Since there are many kinds of movement disorder, dystonia can be classified in various ways , for example, by age of onset, where it occurs in the body, or if it is a primary or secondary condition. (medicalnewstoday.com)
  • idiopathic
  • The lack of prompt response to anticholinergic drugs in cases of idiopathic Meige's syndrome is important in differentiating it from acute dystonia, which does respond to anticholinergics. (wikipedia.org)
  • eyelids
  • The main concern for this dystonia is that it can cause the eyelids to close involuntarily and for indefinite periods of time. (wikipedia.org)
  • commonly
  • Myoclonus is a precursor effect to myoclonus dystonia and most commonly begins in childhood or adolescence. (wikipedia.org)
  • When dystonia starts in childhood it usually begins in the leg or foot and commonly spreads to involve the entire body. (netdoctor.co.uk)
