Study Description

Brief Summary:

The purpose of this study is to compare the clinical effectiveness of two types of chiropractic spinal manipulation to conservative medical care for patients at least 55 years old with sub-acute or chronic LBP.

Condition or disease	Intervention/treatment	Phase
Low Back Pain	Other: HVLA-SM; Other: LVVA-SM; Other: Usual Medical Care	Not Applicable

Detailed Description:

Despite the high prevalence of LBP and the associated economic costs, disability, and lost productivity, and despite the development of several treatment guidelines, one of which recommends chiropractic spinal manipulation for some subgroups of patients with back pain, the management of LBP remains controversial and highly variable across professions and geographic regions. Although one recent publication describes the design of chiropractic and exercise for seniors with low back or neck pain, no published studies, to our knowledge, have assessed the effectiveness of chiropractic manipulation compared to medical care for older adults with sub-acute or chronic low back pain.

Outcome Measures

Primary Outcome Measures :

1. Roland Morris Low Back Pain Disability Questionnaire (RMDQ) [ Time Frame: Mean change from baseline to week 3 ]
   The RMDQ is a widely used health status measure for low back pain. Scoring of the RMDQ ranges from 0-24, with a higher score indicating an increase in low back pain disability. This outcome displays the mean change in RMDQ from baseline to week 3.

Eligibility Criteria

• Ages Eligible for Study: 21 Years to 55 Years (Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: Yes

Criteria

Inclusion Criteria:

• Age 21 to 55
• Idiopathic mechanical low back pain (LBP) matching classification 1-4 of the Quebec Task Force.
• LBP classified as subacute (onset 4-12 weeks previous) or chronic (onset more than 12 weeks previous), with the current episode occurring at least four weeks prior to the date of contact with the clinic: In order to exclude the greatest proportion of LBP patients that have a favorable natural history of improvement.
• Written Informed Consent
• A minimum baseline score on the Roland Morris Disability Questionnaire (RMQ) of 6 points.

Exclusion Criteria:

• LBP from other somatic tissues as determined by history, examination, and course (e.g. pain referred from visceral conditions).
• LBP diagnosis not meeting Classifications 1 through 4 of the Quebec Task Force, especially the following: low back pain associated with frank radiculopathy defined as typical shooting leg pain; positive straight leg-raising test; an altered lower extremity reflex; a dermatomal sensory deficit; at least one of the following: progressive unilateral muscle weakness or motor loss, or symptoms of cauda equina compression; and CT or MRI evidence of related anatomical pathology (e.g. abnormal disc, stenosis).
• Co-morbid pathology or poor health conditions in patients; Co-morbid conditions and general poor health significantly complicate the prognosis of LBP, and inject a variety of uncontrollable factors in case-management, not to mention experimental analysis and interpretation. Patients who have case histories and physical examination findings indicating other that average good health will be excluded from the study.
• Bone and joint pathology contraindicating patient for SM of the lumbar spine and pelvis: Patients with spinal fractures, tumors, infections, arthropathies, and significant osteoporosis will be referred to appropriate health care.
• Other contraindications for SM of the lumbar spine and pelvis (e.g. bleeding disorders or anticoagulant therapy, extreme obesity).
• Retention of legal advice related to this or a previous LBP episode: Patients with occupational or personal injuries will not be automatically excluded from the study unless they answer yes to a specific question about the retention of legal advice with respect to their LBP episode at the baseline interview.
• Pregnancy: Pregnancy is a contraindication for exposing a patient to ionizing radiation and is a confounding factor in the usual course of LBP.
• Inability to read or verbally comprehend English.
• Clear evidence of narcotic or other drug abuse as determined by history and examination: injects significant confounding factors with respect to internal validity and feasibility.
• Major clinical depression: Patients with scores greater than 17 on the Beck Depression Inventory will be excluded from the study. Patients with evidence of other psychiatric disorders as determined by history and exam will also be excluded.
• Use of manipulative care for any reason within the past 3 months as determined by history: to exclude the possibility of carryover effects.
• Unwillingness to postpone use of all other types of manual treatment for LBP except those provided in the study (including chiropractic and osteopathic SM, physical therapy, and massage) for the duration of the study period: to eliminate confounding effects.
