FAST · Functional Arm Scale for Throwers

22 items · 6 min · 0–100 (modular) · higher is better

1 Before you use it

What it is

A modular alternative to KJOC for throwing athletes, with a general arm function core plus optional throwing- and pitching-specific modules.

Its advantage over KJOC is that it works on an injured athlete who is not currently playing — the core module doesn't assume competition.

When to reach for it

Throwing athletes, particularly mid-rehabilitation when they are not competing and KJOC's competition-based items don't apply.

2 Giving it

Scoring

Modular; the core plus whichever sport modules apply, reported 0–100. Higher is better.

What it doesn’t measure

Tissue status, range or strength.

3 Reading the score

Interpreting it

Interpret against baseline.

Is the change real?

No verified MCID or MDC is carried in our library for this measure, so the number on its own cannot tell you a change is real. Compare it to this patient's own baseline and say what changed functionally.

Student trap. Reaching for KJOC on an athlete who's three weeks post-injury and not throwing. Half its items won't apply — use this instead.
