Landmark Study Proves Benefits and Value of Maintenance Care00 00
|Reference: Senna & Machaly (2011) Does Maintained Spinal Manipulation Therapy for Chronic Nonspecific Low Back Pain Result in Better Long-Term Outcome? SPINE 36 (18) 1427-37.
"This study confirms previous reports showing that spinal manipulation is an effective modality in chronic non-specific LBP especially for short-term effects as the disability and pain scores in our study are significantly reduced in the short-term evaluation - but not in long-term - when compared with the sham manipulation."
Oswestry Disability Score: "At the 4-month and 7-month evaluation the mean disability scores gradually elevated back toward the pretreatment level in the non-maintained SMT group. However disability score in the maintained SMT group continue improving."
This was a prospective single blinded placebo controlled study. That means this is a VERY high quality study. Subjects were randomly assigned to their groups (no bias), there was a control to remove, as much as possible, the chance that improvements were from placebo, and assessments of improvement were performed by a blinded examiner (meaning the examiner did not know which group the patient was from - ie whether the patient had or had not been treated).
CLINICAL IMPLEMENTATION FOR PATIENT RESULTS
Spinal mobility, spinal comfort, and spine-related functional ability and quality of life all showed the exact same trend; the group that received maintenance care not only maintained but increased mobility, comfort, function, and quality of life as time under maintenance care progressed over the 10 months.
For the first time we have peer-reviewed evidence from a well designed study that shows a maintenance chiropractic care program consisting of care every 2 weeks for up to 10 months not only prevents relapse and a waste of initial investment, it pays dividends in continued improvements!
