The cause is related to lesions in upper motor neurons and is generally accompanied by hyperreflexia. Therefore, clonus is used as part of the neurological physical exam to assess the status of a patient’s nervous system.

When reflexes are very brisk, clonusis sometimes seen. Administered by a trained clinician, the SCATS Clonus scale uses passive dorsiflexion to assess clonus. Clonus is rated on a 4-point scale that ranges from: 0 = No reaction 1 = Mild lasting < 3sec 2 = Moderate lasting 3-10 seconds 3 = Severe lasting > 10 seconds Testing for clonus (rhythmic, rapid alternation of muscle contraction and relaxation caused by sudden, passive tendon stretching) is done by rapid dorsiflexion of the foot at the ankle. Sustained clonus indicates an upper motor neuron disorder. Clonus will occur in the foot and leg following a quick movement, if there is an UMN lesion Hyporeflexia is associated with lower motor neuron disease or with decreased sensation.

Clonus can be a condition in itself, or it can be a symptom of another The ankle jerk reflex is mediated by the S1 nerve root. The plantar reflex (Babinski) is tested by coarsely running a key or the end of the reflex hammer up the lateral aspect of the foot from heel to big toe. The normal reflex is toe flexion. If the toes extend and separate, this is an abnormal finding called a positive Babinski's sign. Assessment of deep and superficial reflexes provides information on the integrity of reflex arcs at different levels in the central nervous system. They may be abolished by disease of the lower motor neurone or sensory neurones in the reflex arc, and may be modified by central damage, such as in hyper-reflexic upper motor neurone lesions. 5+: sustained clonus Deep tendon reflexes are normal if they are 1+, 2+, or 3+unless they are asymmetric or there is a dramatic difference between the arms and the legs.

2018-09-02 · Clonus is a type of neurological condition that creates involuntary muscle contractions. This results in uncontrollable, rhythmic, shaking movements. People who experience clonus report repeated The ankle clonus test, a method for evaluating the integrity of the spinal cord during operations for scoliosis, is predicated on the finding that patients recovering from general anesthesia normally have temporary ankle clonus bilaterally. An absence of transient ankle clonus has been shown to indi … This video introduces you to clonus and some of its causes.Disclaimers:-The information in this video only represents the knowledge of the individual(s) depi Two additional scales for the grading of reflex intensity are presented below to help identify similarities and differences that may exist between different scales of measurement.
