Dear Sir/Madam I am extremely concerned by the article by Cools et al. The paper offers an algorithm to the differentiation of external from internal impingement. The basis of their differentiation is purely on the relocation test alone. The only article they reference for this fact is Blevins (1997), which only refers to rotator cuff pathology in athletes. The authors also clearly state the inaccuracy of the relocation test and then discuss the posterior impingement sign, which improves the accuracy. It would be more accurate to use this test to differentiate between internal and external impingement and to run a proper controlled study to ascertain this. The impression given by the authors is that the relocation test is an accurate test for internal impingement, which it is clearly not. |
