Score for weakest neck flexion or extension, as part of the Myasthenia Gravis Composite (MGC)
Neck flexion or extension, weakest
0;1;3;4;
0 = Normal;1 = Mild weakness;3 = Moderate weakness;4 = 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".
