Final answer:
During the 6-month regularly scheduled visit, the doctor performs additional tests to assess muscular strength and sensory systems.
Step-by-step explanation:
During the 6-month regularly scheduled visit, the doctor performs additional tests to assess the patient's muscular strength and sensory systems. The doctor asks the patient to smile, raise eyebrows, stick out the tongue, and shrug shoulders to test muscular strength.
The patient is also asked to indicate when they feel the tip of a pen touch their legs, arms, fingers, and face with their eyes closed to assess sensory function. These tests help the doctor identify any deficits or problems in the patient's muscles and sensory systems.
