The purpose of this article is to present and evaluate a "neuromanual" treatment for frozen shoulder, called the OAT-Manual Capsular Dissection, using local anesthetic while the patient is fully conscious. For this study, shoulder abduction was measured before and after the treatment. The results showed near or complete recovery of shoulder abduction as well as increased muscle strength and decreased pain immediately following the procedure. The experimental group had an average maximum of 51 degrees of abduction in the affected shoulder prior to the OAT procedure. Following the procedure, subjects retained an average of 177 degrees of shoulder abduction 2 days later. Readers of this study familiar with the generally accepted difficulty in achieving even minor results with conservative treatment of frozen shoulder will acknowledge that results such as these without surgery or manipulation under general anesthetic are unprecedented. The results of this study show great promise that the Trigenics® OAT Procedure for frozen shoulder enables patients suffering from this painful and debilitating disorder to achieve a quick recovery.
