atherothrombosis

(ath″ĕ-rō-throm-bō′sĭs) [athero- + thrombosis] Arterial thrombosis. atherothrombotic (ath″ĕ-rō-throm-bot′ik), adj.

athetoid

(ath′ĕ-toyd″) [Gr. athetos unfixed, changeable + -oid] 1. Resembling or affected with athetosis. 2. Aperson affected with athetosis.

athetosis

(ath-ĕ-tō′sĭs) [Gr. athetos + -osis] A condition in which slow, irregular, twisting, snakelike movements occur in the upper extremities, esp. in the hands and fingers. These involuntary movements prevent sustaining the body, esp. the extremities, in one position. All four limbs may be affected, or the involvement may be unilateral. The symptoms may be due to encephalitis, cerebral palsy, hepatic encephalopathy, drug toxicity, or Huntington’s chorea or may be an undesired side effect of prolonged treatment of parkinsonism with levodopa.

 There are several types of athetosis. In athetosis with spasticity, muscle tone fluctuates between normal and hypertonic; often there is moderate spasticity in the proximal parts and athetosis more distally. Modified primitive spinal reflex patterns are often present. In athetosis with tonic spasms, muscle tone fluctuates between hypotonic and hypertonic. Excessive extension or flexion is evident. There are strong postural asymmetry and frequent spinal or hip abnormalities or deformities.

 In choreoathetosis, muscle tone fluctuates from hypotonic to normal or hypertonic. There are extreme ranges of motion. Deformities are rare, but subluxation of the shoulder and finger joints often occurs. Pure athetosis is much rarer than the others. Muscle tone fluctuates between hypotonic and normal. Deformities are rare. Twitches and jerks of muscles or individual muscle fibers are seen, along with slow, writhing, involuntary movements that are more proximal than distal.

 PATIENT CARE: Muscle tone and joint range of motion are assessed; joints are inspected for involuntary movements, spasticity, and joint deformities and subluxations. Degree of interference with activities of daily living and self-image is evaluated. Prescribed therapies are administered and evaluated for desired effects and adverse reactions. Emotional support and acceptance are provided, and the patient is informed about local and national groups and services offering support and information. athetotic (-tot′ik), adj.
