The patient is usually asked to undress, so the neurologist can see the muscles and look for atrophy (shrinkage), twitching, or abnormal movements. Tests are done to evaluate strength in all the major muscle groups. Evaluating Babinski response is an important part of testing the motor system. The neurologist strokes or scratches, heel-to-toe, the outer side of the sole of the foot and in patients over the age of 2, the toes normally curl downward in response. If the toes fan upward, a brain or spinal cord injury is indicated.
