Interventions that temper declining functional status due to aging are critical to the vitality and longevity of the elderly. Conservative, non-drug treatments that address disability and pain may significantly reduce the societal burden associated with spinal dysfunction in this population. Chiropractic and exercise are two such promising therapies, and have yet to be compared in the context of short- versus long-term management.
Unanticipated recruitment challenges and repeated reductions to the award negatively impacted our ability to implement the study as proposed. After careful deliberation among the study's Steering Committee, and approval by the IRB and funding agency, the study has been modified to a 2-treatment comparison (formerly 3 treatments).
As such, the primary aim of this study is to compare the effectiveness of 3 versus 9 months of chiropractic care and exercise in 200 seniors with chronic spinal dysfunction. The primary outcomes are patient-rated neck and back disability.
Additionally, initial inclusion criteria regarding disability ratings have been relaxed to allow more individuals with global spine-related disability to qualify. Specifically, participants now must have:
1. a minimum of 10% disability in both neck and back regions (at least 5/50 on Neck Disability Index (NDI) and Oswestry Disability Index(ODI)) at baseline 1 evaluation, and
2. a combined disability (NDI+ODI) score of at least 25/100 at baseline 1 evaluation.
Secondary aims are to assess between-group differences in patient self-reported pain, general health, improvement, self-efficacy, kinesiophobia, satisfaction, medication use, and objective biomechanical outcomes. Seniors' perceptions and experience with treatment will be assessed through qualitative interviews. Finally, the cost-effectiveness and cost-utility of these interventions will be measured.
Additional secondary aims include assessing within group differences in an additional 18 patients randomized to receive 9 months of exercise only in the earlier phase of this study. Outcomes of these aims include the self-report, biomechanical, and qualitative outcomes listed above (with the exception of cost-effectiveness and cost-utility data).
This project will significantly contribute to the evidence base of conservative, non-drug treatments that address disability and pain in seniors with spinal dysfunction. Identification of effective therapies has tremendous potential to substantially improve the functional status, quality of life, and overall health in the aging population.
