How It Works

Calculate leg spring stiffness using the oscillation method: k = mass x (pi/contact time)^2. Compare bilateral symmetry; asymmetry >15% indicates injury risk or post-injury compensation

Each component has a specific meaning:

  • Oscillation method: k = mass x ^2 — The oscillation method: k = mass x ^2 recorded for the scenario being assessed.

Note: Interpret the leg spring stiffness result against the thresholds and context described above.

How to Use

Enter the oscillation method: k = mass x ^2 for the scenario you are assessing. Calculate leg spring stiffness using the oscillation method: k = mass x (pi/contact time)^2. Compare bilateral symmetry; asymmetry >15% indicates injury risk or post-injury compensation. Use the leg spring stiffness result to inform your calculation.
