1 Before you use it

What it is

WOSI's sibling, built for rotator cuff disease. Twenty-one visual-analogue items across physical symptoms, sport and recreation, work, lifestyle and emotions.

When to reach for it

Rotator-cuff-related presentations where you want more depth than SPADI, and post-operative cuff repair follow-up.

2 Giving it

Scoring

Summed 0–2100, reported as a percentage of normal. Lower is better.

What it doesn’t measure

Instability — use WOSI. And it takes eight minutes, which on a busy list is the real reason SPADI usually wins.

3 Reading the score

Interpreting it

Interpret against baseline.

More granular than SPADI, and it captures work and emotional domains SPADI doesn't touch.

Is the change real?

MCID 26.3 points. Compare the change against this patient's own baseline as well as the figure. SourceMeasured in rotator cuff disease.

Student trap. Choosing it over SPADI on a busy outpatient list and then not getting it completed. The best PROM is the one that actually gets filled in.

This is a learning tool. It does not diagnose patients and does not replace your clinical educator.
