Neuro Exam:
1. Orientation
Does the diver know their own name and age?
Does the diver know the present location?
Does the diver know what time, day and year it is?
Note: Even though a diver appears alert, the answers to these questions may reveal confusion. Do not omit them.
2. Eyes
Have the diver count the number of fingers you display, using two or three different numbers.
Check each eye separately and then together.
Have the diver identify a distant object.
Tell the diver to hold head still, or you gently hold it still, while placing your other hand about 50cm in front of their face. Ask the diver to follow your hand. Now move your hand up and down, then side to side. The diver’s eyes should follow your hand and should not jerk to one side and return.
Check that the pupils are equal in size.
3. Face
Ask the diver to purse their lips. Look carefully to see that both sides of the face have the same expression.
Ask the diver to grit their teeth. Feel the jaw muscles to confirm that they are contracted equally.
Instruct the diver to close the eyes while you lightly touch your fingertips across the forehead and face to be sure sensation is present and the same everywhere.
4. Hearing
Hearing can be evaluated by holding your hand about 60cm from the diver’s ear and rubbing your thumb and finger together.
Check both ears moving your hand closer until the diver hears it.
Check several times and compare with your own hearing.
Note: If the surroundings are noisy, the test is difficult to evaluate. Ask bystanders to be quiet and to turn off unneeded machinery.
5. Swallowing Reflex
Instruct the diver to swallow while you watch the “Adam’s apple” to be sure it moves up and down.
6. Tongue
Instruct the diver to stick out their tongue. It should come out straight in the middle of the mouth without deviating to either side.
7. Muscle Strength
Instruct the diver to shrug shoulders while you bear down on them to observe for equal muscle strength.
Check diver’s arms by bringing the elbows up level with the shoulders, hands level with the arms and touching the chest. Instruct the diver to resist while you pull the arms away, push them back, up and down. The strength should be approximately equal in both arms in each direction.
Check leg strength by having the diver lie flat and raise and lower the legs while you resist the movement.
8. Sensory Perception
Check on both sides by touching lightly as was done on the face. Start at the top of the body and compare sides while moving downwards to cover the entire body.
Note: The diver’s eyes should be closed during this procedure. The diver should confirm the sensation in each area before you move to another area.
9. Balance and Coordination
Note: Be prepared to protect the diver from injury when performing this test.
