Involuntary Movement



Restless Legs Syndrome is characterized by an irresistible urge to move one’s body to stop odd uncomfortable sensations.   It can affect the legs, arms, torso and head.   Moving the affected body part provides temporary relief.  Walking, stretching or yoga may relieve the symptoms. The sensations and the need to move may return immediately after stopping movement or at a later time.

Some people experience minor annoyance while others experience significant impairments in quality of life.


A tremor is a rhythmic muscle contraction and relaxation involving to and fro movements of one or more body parts. Some tremors may be triggered by or become exaggerated during times of stress or strong emotion, when the individual is physically exhausted, or during certain postures or movements.


Myoclonus is a sudden involuntary twitching or jerks of a muscle or a group of muscles.  These twitches are caused by sudden muscle contractions or brief lapses of contractions. Contractions are called positive myoclonus and the relaxations are called negative myoclonus. Severe cases of myoclonus can distort movement and severely limit a person’s ability to sleep, eat, talk and walk.


A tic is a sudden, repetitive, nonrhythmic movement involving discrete muscle groups. There are several medications that are used in the treatment of tics.


Dystonia is characterized by sustained muscle contractions that cause twisting and repetitive movements or abnormal postures.
