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

Administer the ALS Functional Rating Scale-Revised (ALSFRS-R) to assess functional status in amyotrophic lateral sclerosis across 12 items covering speech, swallowing, handwriting, cutting food, dressing, turning in bed, walking, climbing stairs, dyspnea, orthopnea, and respiratory insufficiency

Each component has a specific meaning:

  • 12 items covering speech — The 12 items covering speech recorded for the scenario being assessed.
  • Swallowing — The swallowing recorded for the scenario being assessed.
  • Handwriting — The handwriting recorded for the scenario being assessed.
  • Cutting food — The cutting food recorded for the scenario being assessed.
  • Dressing — The dressing recorded for the scenario being assessed.
  • Turning in bed — The turning in bed recorded for the scenario being assessed.

Note: Interpret the alsfrs-r result against the thresholds and context described above.

How to Use

Enter the 12 items covering speech, swallowing, handwriting, cutting food, dressing, turning in bed for the scenario you are assessing.
