Nine weighted items totalling 0–100. Higher is better.

What it doesn’t measure

Instability, balance, or range in degrees.

3 Reading the score

Interpreting it

Interpret against baseline.

Supports required is a useful item — it captures the transition from boot to shoe that a function score misses.

Is the change real?

MCID 10.5 to 15.0 points at 3 to 6 months, falling to 7.5 to 11.4 at 6 to 12 months. MDC 4.7 to 5.2 points. Compare the change against this patient's own baseline as well as the figure. SourceMeasured in after surgery for an unstable ankle fracture.

Student trap. Using it for a sprain. It was built for fractures and its items assume that trajectory.
