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

Quantify disease severity in Multiple System Atrophy across autonomic, cerebellar, and parkinsonian domains using the UMSARS-based scoring

Each component has a specific meaning:

  • Autonomic — The autonomic recorded for the scenario being assessed.
  • Cerebellar — The cerebellar recorded for the scenario being assessed.
  • Parkinsonian domains — The parkinsonian domains recorded for the scenario being assessed.

Note: Interpret the msa severity result against the thresholds and context described above.

How to Use

Enter the autonomic, cerebellar, parkinsonian domains for the scenario you are assessing. Quantify disease severity in Multiple System Atrophy across autonomic, cerebellar, and parkinsonian domains using the UMSARS-based scoring. Use the msa severity result to inform your calculation.
