Ankle Clonus - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes Ankle Clonus, which is a repetitive dorsiflexion of the ankle in response to one time forcible dorsiflexion. Clonus is repetitive dorsiflexion of the ankle in response to one time forcible dorsiflexion. Clonus is usually accompanied by spasticity. The condition is typically seen in patients with multiple sclerosis, stroke or spinal cord damage. Ankle clonus occurs as a result of an upper motor neuron lesion and the integrity of the spinal cord is tested. Clonus is tested by inducing a stretch of the gastrocnemius muscle. Rapid flexion of the foot which results into dorsiflexion with stretching of the gastrocnemius muscle. Subsequent beating of the foot will occur and clonus that occurs as five beats or more is considered abnormal. Clonus is not fasciculation. Fasciculation is small spontaneous twitches associated with lower motor neuron pathology.
