McArdle Disease (GSD V) Exercise Intolerance Calculator

Assesses McArdle disease (myophosphorylase deficiency) severity using ischemic forearm test surrogate, exercise intolerance grade, myoglobinuria history, and CK baseline to guide safe exercise protocols and sucrose pre-exercise supplementation

Each component has a specific meaning:

• Ischemic forearm test surrogate — The ischemic forearm test surrogate recorded for the scenario being assessed.
• Exercise intolerance grade — The exercise intolerance grade recorded for the scenario being assessed.
• Myoglobinuria history — The myoglobinuria history recorded for the scenario being assessed.
• CK baseline — The ck baseline recorded for the scenario being assessed.

Note: Interpret the mcardle gsd v result against the thresholds and context described above.

Enter the ischemic forearm test surrogate, exercise intolerance grade, myoglobinuria history, CK baseline for the scenario you are assessing. Assesses McArdle disease (myophosphorylase deficiency) severity using ischemic forearm test surrogate, exercise intolerance grade, myoglobinuria history, and CK baseline to guide safe exercise protocols and sucrose pre-exercise supplementation. Use the mcardle gsd v result to inform your calculation.
