* Measurement of the '''subacromial space'''. This is normally in shoulder radiographs is 9–10 mm; this space is significantly greater in men, with a slight reduction with age.<ref name=petersson1984/> In middle age, a subacromial space less than 6 mm is pathological.<ref name=petersson1984>{{cite journal|author=Claes J.
