What is the point of reflex testing?
Reflex testing contributes to accurate bedside diagnosis in many cases of neuromuscular disease, providing localising diagnostic information that cannot be obtained by any other method (including clinical neurophysiological and neuroradiological investigations).
What does a +2 mean on reflex?
a brisk response
2+ = a brisk response; normal. 3+ = a very brisk response; may or may not be normal. 4+ = a tap elicits a repeating reflex (clonus); always abnormal.
What are normal reflex scores?
Reflexes are graded on a scale of 0 to 4. A grade of 2 indicates normal reflexes. A grade of 3 indicates hyperreflexia; 4 indicates hyperreflexia with clonus. Decreased relexes are indicated by 1 (hyporeflexia) or 0 (no reflex elicited, even using the Jurassic maneuver.

How do reflexes work?
The reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc. Reflex arcs act on an impulse before that impulse reaches the brain. [1] Relex arcs can be Monosynaptic ie contain only two neurons, a sensory and a motor neuron.
What reflexes are tested in a spinal cord assessment?
The usual set of deep tendon reflexes tested, involving increasingly higher regions of the spinal cord, includes: Another type of reflex test is called the Babinski test, which involves gently stroking the sole of the foot to assess proper development and function of the spine and cerebral cortex.
What kind of Doctor tests reflexes?
Neurologists (doctors with specialized training in neurology) often perform reflex tests. Physician assistants, physical therapists, and nurses may also test reflexes as they examine or evaluate individuals. Adams, Raymond D., Maurice Victor, and Allen H. Ropper.
