MUSCLES AND NERVES
If a person complains of numbness, weakness, or loss of control in part of his
body, or you want to test it: notice the way he walks and moves. Have him stand, sit,
or lie completely straight, and carefully compare both sides of his body.
Face: Have him smile, frown, open his eyes wide, and squeeze
them shut. Notice any drooping or weakness on one side.
If the problem began more or less suddenly, think of a head
injury (p. 91), stroke (p. 327), or Bell’s palsy (p. 327).
If it came slowly, it may be a brain tumor. Get medical advice.
Also check for normal eye movement, size of pupils (p. 217),
and how well he can see.
Arms and legs: Look for loss of muscle. Notice—or measure—
difference in thickness of arms or legs.
Watch how he moves and walks. If muscle loss or weakness affects the whole
body, suspect malnutrition (p. 112) or a chronic (long-term) illness like tuberculosis.
Have him squeeze your
fingers to compare strength
in his hands
and push and pull with his
feet against your hand.
Any string or
ribbon will do
to check if the
distance around
the arms or legs
is different.
Also have him hold his arms straight
out and turn his hands up and down.
Have him lie down and lift one leg
and then the other.
Note any
weakness or
trembling.
If muscle loss and weakness is uneven or worse on one side, in children, think
first of polio (p. 314); in adults, think of a back problem, a back or head injury, or
stroke.
