Chiropractic management of frozen shoulder syndrome using a novel technique: a retrospective case series of 50 patients

The purpose of this case series is to describe the treatment and outcomes of a series of patients presenting with frozen shoulder syndrome who received a novel chiropractic approach (OTZ Tension Adjustment).The files of 50 consecutive patients who presented to a private chiropractic practice with frozen shoulder syndrome were reviewed retrospectively. Two primary outcomes were extracted from the files for initial examination and at final evaluation: (1) the 11-point numeric pain rating scale and (2) the percentage change in shoulder abduction. Each patient received a series of chiropractic manipulative procedures that focused on the cervical and thoracic spine.Of the case files reviewed, 20 were male and 30 were female; and all were between the ages of 40 and 70 years. The median number of days under care was 28 days (range, 11 to 51 days). The median change in Numeric Pain Rating Scale score was - 7 (range, 0 to - 10). Of the 50 cases, 16 resolved completely (100% improvement), 25 showed 75% to 90% improvement, 8 showed 50% to 75% improvement, and 1 showed 0% to 50% improvement.Most patients with frozen shoulder syndrome in this case series appeared to improve with the chiropractic treatment.
