The clinical diagnosis of stage I or II SIS is made when one or more of the following mentioned factors exist, next to a positive Neer impingement test and a positive Hawkins test.;Patients* history:
- Diffuse unilateral shoulder pain for > 3 months;
- Pain during activities with abduction, retroflexion and/or internal rotation (i.e. closing the door, putting on jacket, overhead activities);
- Pain at night or incapable of lying on the shoulder.;Physical examination:
- Diffuse pain at palpation of the greater tuberosity;
- Disturbed scapulohumeral rhythm;
- Painful arc;
- No complaints or sings of pathologies on the contralateral shoulder;
- > 90 Degrees external rotation in 90 degrees of passive abduction (frozen shoulder);
- Positive Yocum test.
Patients are excluded if one of the following characteristics is found:
- <35 Or > 60 years old
