Brief Summary
It is expected that mechanical low back pain (LBP) is associated with inflammatory changes localized to the affected tissues. Could such changes be detected in cells involved in the inflammatory process in an in vitro model? The investigators wish to test such a model to compare inflammatory markers in acute and chronic LBP patients and also examine the effect of spinal manipulative treatment (SMT) on changing the level of selected key inflammatory markers. The investigators hypothesize that:
- 1.Proinflammatory markers will be elevated while antinflammatory markers will be reduced in acute LBP patients relative to chronic back pain patients as well as in healthy study participants who have no LBP or any inflammatory conditions (controls).
- 2.SMT will cause a reduction in the production of proinflammatory markers while anti-inflammatory markers will increase relative to baseline levels as well as relative to controls

Outcome Measures
Primary Outcomes (1)
Determining proinflammatory cytokine (TNFα and IL-1β) levels in acute and chronic low back pain patients and in healthy asymptomatic subjects.
Supernatants from whole blood cultures are collected 24 or 48 hours postincubation, are dispensed in 0.5-1.0 ml aliquots and stored at 76C. Because subject recruitment occurs over a long period,it is not desirable to process samples sporadically. This approach allows using same-batch reagents/bioassay kits for all samples in an effort to decrease error and enhance internal consistency. Results will be expressed as the difference between the values obtained for acute, chronic and control at baseline.
Baseline (time zero) determinations to compare acute vs chronic vs control.
Secondary Outcomes (1)
Determining if spinal manipulative treatment will cause significant changes in the level of proinflammatory cytokine production in vitro.
Baseline and 2 weeks i.e on the 7th visit of patients.
Other Outcomes (1)
Determining the levels of anti-inflammatory mediators (IL-10, IL-1ra) and chemokines produced in the same cultures.
Baseline and 2 weeks i.e on the 7th visit of patients.
Study Arms (3)
Acute versus chronic low back pain
NO INTERVENTIONNo manipulative intervention. Phlebotomy for inflammatory biomarker determinations to compare acute versus chronic at baseline.
Spinal manipulation (SMT)
EXPERIMENTALInflammatory biomarker determinations after a course of 6 SMT interventions over the period of 2 weeks; a single SMT per treatment.
No treatment controls
NO INTERVENTIONAsymptomatic subjects. Biomarker determinations at time zero and again two weeks later.
Interventions
Spinal manipulation will consist of a single high velocity low amplitude thrust to a hypomobile vertebral segment determined by the treating clinician to contribute to the problem.
Eligibility Criteria
You may qualify if:
- For Asymptomatic controls:
- Adults between the ages of 20 and 60 years
- No pain of any etiology
- No inflammatory conditions including musculoskeletal complaints
- No diabetes
- No neoplasms
- No spinal manipulative treatments for the past 4 weeks
- Willing to sign informed consent
- For low back patients:
- Adults between the ages of 20 and 60 years
- Having low back pain of no longer than 4 weeks (acute) or longer than 12 weeks (chronic), with or without radiation to the lower extremity.
- No fractures
- NoInflammatory conditions
- No other pain complaints
- No diabetes
- +2 more criteria
You may not qualify if:
- \<20 or \>60 years of age.
- Having experienced low back pain longer than 4 wks but less than 12 wks
- Experiencing less than 3/10 pain as judged by a VAS score determined at time of presentation to study.
- Failure of clinician to locate a musculoskeletal indicator that will reproduce/localize the patient's pain (e.g., localized muscle tightness, soft tissue tenderness, reproduction of symptoms on digital joint challenge).
- Currently experiencing significant pain (sprain/strain) anywhere in the body other than the low back.
- Having been diagnosed with back pain of non-mechanical origin, including seronegative arthropathies, fibromyalgia, inflammatory joint conditions, infections, and tumors.
- Having been diagnosed with inflammatory conditions in the past (e.g autoimmune diseases, psoriasis), or currently experiencing any inflammatory condition(s) (e.g. allergies, tooth extraction or other dental work).
- Having been diagnosed with/experienced any infections in past 4 weeks (including common cold, oral/genital herpes, etc).
- Having a blood clotting disorder.
- Having received anti-inflammatory, immunosuppressive, immunostimulatory (e.g. immunization) or anticoagulant medications during the past 2 weeks.
- Having received a spinal manipulative treatment during the past 4 weeks.
- Unwilling to sign study consent form.
- Unwilling/unable to adhere to study schedule. -
