Patients were unknowingly randomly assigned to one of two groups, a control group and an experimental group. One group maintained current medication levels and underwent a specific exercise routine using Pilates. The other group continued current medication but a specific exercise routine was not provided. A researcher who did not know to which group patients belonged, evaluated patients at several time points including at 45, 90 and 180 days. Patients were assessed for pain, flexibility, and pain medication intake among other things. At the end of the study it was found that the Pilates exercise group had decreased pain and decreased use of pain medications, as well as increased flexibility.
