Steroid myopathy
Myopathy is defined as any abnormal
condition or disease of the muscle tissues, commonly involving skeletal tissue. Certian
drugs can cause myopathy.
Steriod myopathy is muscle disease or weakness caused from over use of steroids
especially Corticosteroids.
Symptoms of steroid myopathy
Chronic (classic) steroid myopathy
- Proximal muscle weakness is more pronounced than 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 pectoral
girdle muscles.
- Muscle bulk typically is normal, but muscle atrophy can occur.
- Muscle stretch reflexes typically are normal.
- Sensory examination should be normal.
Acute steroid myopathy
- Generalized muscle weakness, not limited to a more proximal distribution, is noted.
- Muscle stretch reflexes typically are normal.
- Sensory examination should be normal.
