Techniques were chosen from experience

I note that anteroposterior techniques were the most commonly used techniques for treating the glenohumeral joint to relieve shoulder pain and stiffness. As a clinician I have often found this technique to be unreliable or ineffective at best, and at other times to exacerbate pain in the shoulder. I would be interested to know whether the results would have been different if other commonly used techniques had been employed (eg, caudad glides, Mulligan-style mobilisations with movement, techniques using a seat belt etc.)
