intention tremor

tremor /trem·or/ (trem´er) an involuntary trembling or quivering.

---

action tremor  rhythmic, oscillatory, involuntary movements of the outstretched upper limb; it may also affect the voice and other parts.

coarse tremor  one in which the vibrations are slow.

essential tremor  a hereditary tremor with onset usually at about 50 years of age, beginning with a fine rapid tremor of the hands, followed by tremor of the head, tongue, limbs, and trunk.

fine tremor  one in which the vibrations are rapid.

flapping tremor  asterixis.

intention tremor  action t.

parkinsonian tremor  the resting tremor seen with parkinsonism, consisting of slow regular movements of the hands and sometimes the legs, neck, face, or jaw; it typically stops upon voluntary movement of the part and is intensified by stimuli such as cold, fatigue, and strong emotions.

physiologic tremor  a rapid tremor of extremely low amplitude found in the legs and sometimes the neck or face of normal individuals; it may become accentuated and visible under certain conditions.

pill-rolling tremor  a parkinsonian tremor of the hand consisting of flexion and extension of the fingers in connection with adduction and abduction of the thumb.

resting tremor  tremor occurring in a relaxed and supported limb or other bodily part; it is sometimes abnormal, as in parkinsonism.

senile tremor  that due to the infirmities of old age.

volitional tremor  action t.

intention tremor,

fine, rhythmic, purposeless movements that tend to increase during voluntary movements. Compare resting tremor. See also tremor.

intention

a manner of healing, e.g. first intention when a surgical incision heals immediately, second intention when a gaping wound fills with granulation tissue and is then covered from the sides with epithelium. See also wound healing.

---

intention tremor

tremor of the head or a limb which increases as the patient tries to perform a particular function, e.g. following a moving object by moving the head. See also intention tremor.

---

tremor

a continuous repetitive twitching of skeletal muscle, usually palpable and visible. The diseases characterized by tremor only, the tremor syndromes, may be caused by degenerative disease of the nervous system, e.g. hypomyelinogenesis, and by many toxins, especially plant ones. Tremor is also a sign in many other diseases of the nervous system.

action tremor

rhythmic, oscillatory, involuntary movements of the limbs.

coarse tremor

that involving large groups of muscle fibers contracting slowly.

congenital tremor syndrome of piglets

see congenital tremor syndrome.

epidemic tremor

see avian encephalomyelitis.

fibrillary tremor

rapidly alternating contraction of small bundles of muscle fibers.

fine tremor

one in which the vibrations are rapid.

intention tremor

one occurring when voluntary movement is attempted. See also volitional tremor (below).

rest tremor

tremor occurring in a relaxed and supported limb.

tremor syndrome

see shaker dogs. Called also white dog shaker syndrome.

volitional tremor

trembling of the entire body during voluntary effort.
