The ankle clonus reflex is elicited by rapid dorsiflexion of the foot followed by continued application of pressure to hold the foot in slight dorsiflexion. Rhythmic

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 is a rhythmic, oscillating, stretch reflex, the cause of which is not totally known; however, it relates to lesions in upper motor neurons and therefore is generally accompanied by hyperreflexia. Therefore, clonus is used as part of the neurological physical exam to evaluate the status of a patient’s nervous system. Clonus is a set of involuntary and rhythmic muscular contractions and relaxations. Clonus is a sign of certain neurological conditions, particularly associated with upper motor neuron lesions involving descending motor pathways, and in many cases is, accompanied by spasticity (another form of hyperexcitability).

An absence of transient ankle clonus has been shown to indi … 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. Mayo Clinic scale for tendon reflex assessment.

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 …
