Which reflex assessment includes stroking from the lateral malleolus to the small toe?

Chaddock's reflex is assessed by stroking the skin of the lateral malleolus towards the small toe. This reflex test is one of the cutaneous reflexes that evaluate the integrity of the corticospinal tract and peripheral nervous system. It primarily tests the response of the plantar flexor muscles as a reaction to stimulation of the skin, and it can indicate neurological issues if the reflex is exaggerated or absent.

In contrast, the other reflexes mentioned serve different functions or are assessed in different ways. Oppenheim's reflex, for example, involves a similar mechanism but is assessed by running a finger down the anterior tibia. Gordon's reflex is assessed differently, focusing on squeezing the calf muscle rather than specific stroking of the foot. The patellar reflex, on the other hand, involves a direct tap on the patellar tendon to assess the knee-jerk response.

Chaddock's reflex is particularly important in neurological examinations as it helps clinicians gather information about potential underlying conditions affecting the nervous system.
