The Parks–Bielschowsky three-step test, [1] also known as Park's three-step test or Bielschowsky head tilt test, [2] is a method used to isolate the paretic extraocular muscle, particularly superior oblique muscle and trochlear nerve (fourth cranial nerve), [3] in acquired vertical double vision. [4] It was originally described by Marshall M ...
The cranial nerve exam is a type of neurological examination.It is used to identify problems with the cranial nerves by physical examination.It has nine components. Each test is designed to assess the status of one or more of the twelve cranial nerves (I-XII).
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [1] but not deeper investigation such as neuroimaging.
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.

The cerebellum provides the motor control that allows people to maintain balance by integrating three types of sensory input: vestibular (inner ear and eight cranial nerves), proprioceptive (peripheral nerves and dorsal columns of the spinal cord), and visual (eyes and second cranial nerves). Now, Romberg's test evaluates postural instability ...
The test can be performed by tapping the triceps tendon [3] [note 1] with the sharp end of a reflex hammer while the forearm is hanging loose at a right angle to the arm. A sudden contraction of the triceps muscle causes extension, [note 2] and indicates a normal reflex. [4] [5]
