If desired, a reflex hammer of any type would be adequate equipment to test this reflex. Technique Eliciting the clonus reaction can be done in the same manner as eliciting a muscle stretch reflex, which involves tapping the tendon of the joint when it is in a relaxed position often at ninety degrees of flexion (see MSR Statpearls article for a more detailed description of these techniques).
