During PMS testing, which component includes testing sensation in all four extremities?

• A. Sensory
• B. Pulse
• C. Motor
• D. Reflexes

Answer: (A)

In PMS testing, the sensory component covers testing sensation in all four extremities. This part of the quick neuro exam checks how well the patient can feel light touch (and sometimes pain) in both arms and both legs, comparing sides to look for any loss or change in sensation. Detecting such deficits helps identify potential nerve or spinal injuries that require urgent attention. Pulses assess blood flow to the limbs, motor checks assess the ability to move each limb, and reflexes look at automatic nerve circuits—none of these specifically map out the sensory ability across all four limbs like the sensory portion does.
