Chronic (classic) steroid myopathy physical findings are as follows:

  • Proximal muscle weakness is more pronounced than is distal muscle weakness; however, severe relative weakness of the anterior tibialis muscle can be found.

  • Pelvic girdle muscles usually are affected more severely and earlier than are pectoral girdle muscles.

  • Muscle bulk typically is normal, but muscle atrophy can occur.

  • Muscle stretch reflexes typically are normal.

  • Sensory examination should be normal.
