Introduction to the Reflexes

The reflex examination is important for several reasons. Reflex changes may be the earliest and most subtle indication of a disturbance in neurologic function. The testing of reflexes is the most objective part of the neurologic examination. Reflexes are under voluntary control to a lesser extent than most other parts of the neurologic examination, and reflex abnormalities are difficult to simulate. They are not as dependent on the attention, cooperation, or intelligence of the patient and can be evaluated in patients who cannot or will not cooperate with other parts of the examination. In such circumstances, the integrity of the motor and sensory systems can sometimes be appraised more adequately by the reflex examination than by other means. Although the reflex examination is an essential component, it is only one part of the neurologic examination and must be evaluated in the context of the other findings.
