Restless Finger Syndrome

Save

Twitches, tics and other involuntary motions of the finger are a type of movement disorder or dystonia. Although such spasms can be symptoms of many conditions, restless fingers are frequently associated with writer’s cramp and musician’s cramp.

Causes

  • Writer’s and musician’s cramps result from repetitive use of muscles in the hand, forearm or fingers. Spasms occur when opposing muscles contract simultaneously.

Terms

  • Dystonia--muscle tone dysfunction--can affect almost any part of the body, or multiple parts. When only one part is affected, such as the finger, it is termed a focal dystonia.

Considerations

  • Typists, draftsmen and others who perform repetitive motions in their work, as well as writers and musicians, may suffer from focal dystonia, which can be considered an occupational disorder.

Progression

  • Initially, involuntary movements may occur when the finger or other body part is involved in a voluntary action. As the condition worsens, the movements may appear even when the body part is resting.

Treatments

  • Treatments for writer’s and musician’s cramps may include relaxation techniques and hypnosis, administration of botulinum toxin, or surgery.

Serious disorders

  • Severe diseases that may cause uncontrolled movements such as restless finger include Parkinson’s Disease and Huntington’s Disease. These are progressive and degenerative disorders that affect the brain and nervous system.
