Quizplus · Accepted Answer

Test the ankle clonus when reflexes are hyperactive. Support the patient's knee in a flexed position and briskly dorsiflex the foot with your other hand. If clonus is present, there is recurrent ankle plantar flexion movement as long as the examiner retains the foot in dorsiflexion. Sustained clonus signifies the hypertonia of an upper motor neuron lesion.
