A series of muscular contractions due to sudden stretching of the muscle, -- a sign of certain neuropathies.
The foot is dorsiflexed by the examiner. eliciting repetitive, uncontrolled. up and down motion of the ankle. A positive test indicates pressure upon the spinal cord.
An abnormal response to the stretching of a muscle. It consists of a series of rhythmic involunary muscle contractions that occur in response to a single stretch, such as tapping the tendon to elicit a muscle stretch reflex.
An abnormality in neuromuscular activity characterized by rapidly alternating muscular contraction and relaxation.
increase in involuntary muscle tone and subsequent movement that results in spasm
involuntary rhythmic movements due to an upper motorneuron lesion and exaggerated reflexes.
series of alternating contractions and relaxations of a muscle.
'turmoil'. Rapid beating movement at ankle or wrist produced by sudden passive extension; associated with upper motor neuron disease ( Ch. 13).
Involuntary movement of rapidly alternating contraction and relaxation of a muscle. Ankle Clonus is the most common form of Clonus.
Rapid cycles of muscle contraction and relaxation.
A series of alternating muscle contractions and partial relaxations that produce a convulsive spasm.
convulsion characterized by alternating contractions and relaxations
a contraction or relaxation of muscles while a clupeid is a herring
a neurological finding observed as a spasmodic reflex in the ankle due to a compression or injury of the spinal cord.
An abnormal movement characterized by rapid contraction and relaxation of muscles.
Rapidly alternating contraction and relaxation of a muscle. Ankle clonus is the most common form of clonus. The spasms in the calf muscle makes the foot and leg bounce up and down. It is a sign of spasticity.
Spasmodic alternation of muscular contraction and relaxation.
Spasm in which rigidity and relaxation alternate in rapid succession
A sustained series of rhythmic jerks following quick stretch of a muscle.
Alternate muscle contraction and relaxation in rapid succession.
Brisk increase in tone with involuntary movements that result in dysfunction of the corticospinal tracts.
Alternate muscular contraction and relaxation in rapid succession.
Rapid, rhythmic movement that may occur in spastic muscles.
A lengthy state of alternating involuntary contraction and relaxation of a muscle.
Clonus is a particular form of spasticity that occurs in response to a rapid stretching of a muscle, most often in the knee or foot. The response is a rapid rhythmic movement that may continue as long as the muscle is stretched or may gradually lessen.
A rhythmical contraction of the muscle in response to a sudden applied and then sustained stretch stimulus.
Rapid, rhythmic movements (alternate muscle relaxation and contractions).
A characteristic of an upper motor neuron lesion; involuntary alternating spasmotic contraction of a muscle precipitated by a quick stretch reflex.
Involuntary, rapid contractions and relaxations of a muscle.
