Chiropractic and Exercise for Seniors With Low Back Pain

Low back pain (LBP) is a significant health problem for both young and geriatric individuals. Of particular concern is that conditions associated with LBP, such as impaired strength and flexibility, can have very serious consequences for an older individual's independence and overall health.

The broad, long-term objective of this research is to identify effective therapies for low back pain (LBP) and to discover the best methods for enhancing health and functional capacity in the elderly population. This study is a multi-methods clinical trial consisting of a randomized clinical trial (RCT), a cost-effectiveness study alongside the RCT, and a qualitative study nested in the RCT.

This trial builds upon a previous study of chiropractic and exercise funded by HRSA, and focuses on elderly patients with sub-acute and chronic low back pain.

PRIMARY AIMS

• To determine the relative clinical effectiveness the following treatments for LBP patients 65 years and older in both the short-term (after 12 weeks) and long-term (after 52 weeks), using low back pain as the main outcome measure

• chiropractic manual treatment plus home exercise
• supervised rehabilitative exercise plus home exercise
• home exercise

SECONDARY AIMS

• To estimate the short- and long-term relative effectiveness of the three interventions using:
• Patient-rated outcomes: low back disability, general health status, patient satisfaction, improvement, and medication use measured by self-report questionnaires
• Objective functional performance outcomes: spinal motion, trunk strength and endurance, and functional ability measured by examiners masked to treatment group assignment
• Cost measures: direct and indirect costs of treatment measured by questionnaires, phone interviews, and medical records.
• To describe elderly LBP patients' perceptions of treatment and the issues they consider when determining their satisfaction with care using qualitative methods nested within the RCT.

Inclusion criteria

• Sub-Acute and chronic low back pain (Defined as current episode more than 6 weeks duration.)

Exclusion criteria

• Significant infectious disease Determined by history or by referral to supplementary diagnostic tests
• Ongoing treatment for low back pain by other health care providers
• Mean baseline low back pain score of 20 percentage points or less
• Contraindications to exercise Determined by history or by referral to supplementary diagnostic tests (i.e., uncontrolled arrhythmias, third degree heart block, recent ECG changes, unstable angina, acute myocardial infarction, acute congestive heart failure, cardiomyopathy, valvular heart disease, poorly controlled blood pressure, uncontrolled metabolic disease
• Contraindications to spinal manipulation (i.e. Progressive neurological deficits blood clotting disorders; infectious and non-infectious inflammatory or destructive tissue changes of the spine; severe osteoporosis)
