Ankle clonus. Grade 4 ankle hyper reflexia is called ankle clonus. There is repetitive ankle dorsiflexion and plantarflexion on passive dorsiflexion of the foot by the examiner till the force applied by the examiner is withdrawn. Causes. Any spinal cord lesions, be it traumatic, neoplastic, pyogenic, vascular above the level of S1 can cause clonus.

In these experiments clonus was maintained by continual stretch of the triceps surae while the excitability of the motoneurons performing clonus was examined by putting in three kinds of test stimuli with different delays after the preceding clonic burst. These added stimuli were afferent volleys elicited by tendon taps, H-reflex stimulation, and vibration of the Clonus refers to a neurological condition in which the nerve cells that control the muscles are damaged and send faulty signals.

People with ankle clonus may have difficulty walking. Clonus may be found at the ankle, patella, triceps surae, wrist, jaw, biceps brachii. In general, clonus may occur in any muscle with a frequency of 5-8 Hz and the average period of oscillations of the ankle clonus is approximately 160-200 ms.

Briskly dorsiflex and partially evert the foot, sustaining the pressure (do not leave the hand after dorsiflexing). Clonus is felt as repeated beats of dorsiflexion/plantar flexion. 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).

The ankle clonus test is a diagnostic test wherein doctors induce dorsiflexion (flexing the foot back and forth) to look for abnormal reflex movements of the foot. Deep tendon reflexes are used to understand the response of the muscles. The test is very simple to perform.

3 and 4 are not routinely practised in clinical neurology. Medical conditions that can cause clonus include: 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 Clonus most commonly affects muscles at the ends of limbs, including ankles, wrists, etc. Clonus can also be caused by a medical condition such as multiple sclerosis, Huntington disease, spinal These rhythmic oscillations (clonus) are most easily elicited in the foot (usually with oscillations of 5 to 8 Hz), by briskly dorsiflexing the patient’s ankle.

In general, clonus may occur in any muscle with a frequency of 5-8 Hz and the average period of oscillations of the ankle clonus is approximately 160-200 ms. Plantar flexion (PF) comprises 45% of the period, dorsifleksion (DF) comprises 55% of the period. Ankle clonus is an involuntary tendon reflex that causes repeated flexion and extension of the foot.
