Fibrodysplasia Ossificans Progressiva (FOP) Flare Severity Score

Assesses FOP episodic flare severity using warmth, swelling, pain, and ROM restriction, estimates new heterotopic ossification volume from MRI, and guides palovarotene dosing for flare prevention.

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

Assesses FOP episodic flare severity using warmth, swelling, pain, and ROM restriction, estimates new heterotopic ossification volume from MRI, and guides palovarotene dosing for flare prevention

Each component has a specific meaning:

  • Warmth — The warmth recorded for the scenario being assessed.
  • Swelling — The swelling recorded for the scenario being assessed.
  • Pain — The pain recorded for the scenario being assessed.
  • ROM restriction — The rom restriction recorded for the scenario being assessed.
  • Estimates new heterotopic ossification volume from MRI — The estimates new heterotopic ossification volume from mri recorded for the scenario being assessed.
  • Guides palovarotene dosing — The guides palovarotene dosing recorded for the scenario being assessed.

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

How to Use

Enter the warmth, swelling, pain, ROM restriction, estimates new heterotopic ossification volume from MRI, guides palovarotene dosing for the scenario you are assessing. Assesses FOP episodic flare severity using warmth, swelling, pain, and ROM restriction, estimates new heterotopic ossification volume from MRI, and guides palovarotene dosing for flare prevention. Use the fop flare score result to inform your calculation.
