| C16608 | Myasthenia Gravis Composite (MGC) - shoulder abduct weak score | MGCShoulderAbductWeakScore | Score for weakness in shoulder abduction, as part of the Myasthenia Gravis Composite (MGC) | Score for weakness in shoulder abduction, as part of the Myasthenia Gravis Composite (MGC) | Shoulder abduction | 0;2;4;5 | 0 = Normal;2 = Mild weakness;4 = Moderate weakness;5 = Severe weakness | Numeric Values |
Physical examination "Moderate weakness" should be construed as weakness that equals roughly 50% +/- 15% of expected normal strength. Any weakness milder than that would be "mild" and any weakness more severe than that would be classified as "severe". |
