2008 ICD-9-CM Diagnosis 781.0

Abnormal involuntary movements

  • An involuntary contraction of a muscle or group of muscles. Spasms may involve skeletal muscle (MUSCLE, SKELETAL) or smooth muscle (MUSCLE, SMOOTH).
  • Cyclical movement of a body part that can represent either a physiologic process or a manifestation of disease. Intention or action tremor, a common manifestation of CEREBELLAR DISEASES, is aggravated by movement. In contrast, resting tremor is maximal when there is no attempt at voluntary movement, and occurs as a relatively frequent manifestation of PARKINSON DISEASE.
  • Involuntary contraction of the muscle fibers innervated by a motor unit. Fasciculations can often by visualized and take the form of a muscle twitch or dimpling under the skin, but usually do not generate sufficient force to move a limb. They may represent a benign condition or occur as a manifestation of MOTOR NEURON DISEASE or PERIPHERAL NERVOUS SYSTEM DISEASES. (Adams et al., Principles of Neurology, 6th ed, p1294)
  • Tremor is the shaking movement of the whole body or just a certain part of it, often caused by problems of the neurons responsible for muscle action. (from Wikipedia)
