It's ironic because I was just reading a systematic review in BJSM about sub-acrominal impingement syndrome (SAPS) that reviewed the various interventions. Exercise had the most support, and therapeutic taping (or Kinesio taping) had no effect compared to placebo. I've also seen articles that say that taping has no effect on lumbar or thoracic pain. It's one more tool, but there are better tools to master (exercise, manual therapy, patient education, etc.). I definitely would not spend a thousand dollars to take one of these courses. You're better off going to a Mulligan, Maitland, or Chad Cook course.
