Involuntary spasms of muscle contraction that cause abnormal movements and postures. The dystonia that occurs most frequently in PD is in the foot and is a characteristic of PD.
A persistent posture or position, which seems to occur when an athetoid movement becomes "frozen" at one of its extremes. For example, the hand may remain painfully over-flexed for minutes at a time. The localization of the damage is not clear, but the extrapyramidal system is involved.
Impaired or disturbed tonicity: tone fluctuates in an unpredictable manner from low to high.

movement disorder in which there is a fixed abnormal posturing of a part of the body X Y Z
1. A state of abnormal (either hypo – little movement- or hyper – excessive movement) tonicity in any of the tissues resulting in impairment of voluntary movement. 2. A neurologic movement disorder characterized by sustained muscle contractions, resulting in repetitive, involuntary, twisting or writhing movements and unusual postures or positioning. Dystonia may be limited to specific muscle groups (focal dystonia), such as dystonia affecting muscles of the neck (cervical dystonia or spasmodic torticollis) or the eyes, resulting in closure of the eyelids (blepharospasm). 3. Dystonia is associated with certain underlying genetic disorders, such as dystonia musculorum deformans, dopa-responsive dystonia, and paroxysmal kinesigenic and paroxysmal non-kinesigenic dystonic choreoathetosis. The condition may result from the use of certain medications, lack of oxygen during or immediately after birth, or other causes of brain trauma.
involuntary slow, sustained muscle contractions which result in abnormal postures and twisting motions of arm(s), leg(s), trunk.
Impaired or abnormal muscular tension, resulting in involuntary spasmodic movements and loss of function. It may be generalised or restricted to one part of the body.
Disordered tonicity of muscles.
causes slow jerky movements which are most likely to occur in the trunk, neck and proximal parts of the limbs.
A condition characterized by contractions or spasms of muscles. Dystonia can cause twisting and repetitive movements or abnormal postures.
abnormal muscle tone leading to abnormal postures of body parts.
Slow twisting movements, sustained postures, and muscles cramps.
Involuntary spasms of muscle contraction that cause abnormal movements and postures. May appear as a side effect of long term drug treatment in Parkinson's and may worsen in response to stress.
a disorder of the basal ganglia
a movement disorder characterized by forceful, inappropriate contraction of muscle groups
An involuntary, sustained muscle contraction that frequently causes twisting and repetitive movements or abnormal postures. close window
Impaired or disordered muscle tone
(dystonic) a condition of abnormal muscle tone.
dis TOH nee uh] Sustained involuntary muscle contraction.
Neurological disorder characterized by involuntary muscle contractions; can affect any part of the body.
a slow movement or extended spasm in a group of muscles.
slow twisting involuntary movement, associated with forceful muscle contractions or spasms.
slow, twisting movements which may involve one limb or several limbs.
Involuntary twisting of the body due to abnormal muscle contractions
Involuntary slow, sustained muscle contractions resulting in abnormal postures and twisting motions of arms, legs, and trunk.
A movement disorder characterized by sustained muscle contractions, usually producing twisting and repetitive movements or abnormal postures or positions.
Involuntary muscle spasms that cause abnormal movements and awkward positions of a hand, foot, or other part of the body with rigidity and twisting--may be painful--may worsen in response to stress
alteration in muscle tone, usually referring to muscle cramps/spasms of muscles close to the midline of the body (neck, shoulders, hips). Partial loss of the ability to coordinate and perform certain purposeful movements and gestures in the absence of motor or sensory impairments.
a motor disturbance characterised by slow, sustained contractions of muscles. One movement often predominates, leading to relatively sustained postural deviations. Common varieties include spasms of the tongue, neck, or eye muscles. Acute dystonic reactions such as facial grimacing may be seen as a side-effect of some drugs.
Abnormally increased muscular tone that causes fixed abnormal postures; sometimes shifting postures result from irregular, forceful twisting movements that affect the trunk and extremities. A persistent attitude or posture in one or other of the extremes of athetoid movement, produced by co-contraction of agonist and antagonist muscles in one region of the body.
An extrapyramidal symptom (EPS) caused by some antipsychotic medicines. The main features are sticking out the tongue, abnormal head position, grimacing, neck spasms, and eyes rolling up. (See torticollis.)
involuntary, uncontrollable muscular contractions or movements
(dis-to-ne-ah): An extrapyramidal symptom (EPS) caused by some antipsychotic medicines. The main features are sticking out the tongue, abnormal head position, grimacing, eyes rolling up and neck spasm. (See torticollis.)
Abnormal and awkward posture or sustained movements of a hand, foot, or other part of the body; may be accompanied by rigidity and twisting
Prolonged muscle contractions that may cause twisting and repetitive movements or abnormal posture.
Closely related to athetosis, however there is larger axial muscle involvement rather than appendicular muscles.
impaired muscle tonus
Acute tonic muscular spasms, often of the tongue, jaw, eyes, and neck, but sometimes of the whole body. Sometimes occurs during the first few days of antipsychotic drug administration.
abnormal muscle tone of one or more muscles.
Dystonia is a neurological movement disorder in which sustained muscle contractions cause twisting and repetitive movements or abnormal postures.Dystonia fact sheet: National Institute of Neurological Disorders and Stroke http://www.ninds.nih.gov/disorders/dystonias/detail_dystonias.htm The disorder may be inherited or caused by other factors such as birth-related or other physical trauma, infection or reaction to drugs.
