Frequency of clonus: 5-8 Hz and the average period of oscillations of the ankle clonus is approximately 160–200 ms with plantar flexion comprising 45% of the period and dorsiflexion 55% of the period. Literature suggests that the duration of the dorsiflexion around 88.63±10.83 ms, and the duration of the plantarflexion 71.75±6.73 ms. 2021-01-22 · In someone with ankle clonus, a series of five or more uncontrolled muscle contractions and relaxations will occur, causing the ankle to jerk repeatedly.

Deep tendon reflexes are used to understand the response of the muscles. The test is very simple to perform. 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. 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.
