Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate the Quantitative Myasthenia Gravis (QMG) score to objectively assess the degree of neuromuscular dysfunction across 13 items including ocular, bulbar, and limb function

Each component has a specific meaning:

  • 13 items including ocular — The 13 items including ocular recorded for the scenario being assessed.
  • Bulbar — The bulbar recorded for the scenario being assessed.
  • Limb function — The limb function recorded for the scenario being assessed.

Note: Interpret the qmg score result against the thresholds and context described above.

How to Use

Enter the 13 items including ocular, bulbar, limb function for the scenario you are assessing. Calculate the Quantitative Myasthenia Gravis (QMG) score to objectively assess the degree of neuromuscular dysfunction across 13 items including ocular, bulbar, and limb function. Use the qmg score result to inform your calculation.
