The efficacy of shoulder adjustments in the treatment of rotator cuff tendinitis

Abstract

Purpose . Rotator cuff tendinitis is a common problem, however, its diagnosis and management is not completely understood. The purpose of this research project was to investigate the efficacy of the chiropractic adjustment to determine whether or not it is an effective approach in the treatment of rotator cuff tendinitis. Methods This randomized controlled trial consisted of two groups. Each group consisted of thirty subjects, of any age, selected from the general population and randomly allocated to Group 1 or 2, participation in this trial was voluntary. Group 1 received chiropractic adjustment of the glenohumeral or acromioclavicular joint according to the fixations found on motion palpation and group 2 received placebo laser. Subjects in both groups had to comply with certain inclusion criteria before being allowed to participate in the study. Goniometer readings were taken to measure range of motion, algometer readings to measure pain threshold and the Numerical Pain Rating Scale was answered at the initial consultation, and on the third and sixth consultations. The Unpaired and Friedman's T- tests were used to assess the intra and intergroup information from the first, third and sixth consultations. Groups 1 and 2 were compared in terms of age, gender, race and clinical severity prior to onset.
