The short-term effect of a spinal manipulation on pain/pressure threshold in patients with chronic mechanical low back pain.

OBJECTIVE: The purpose of this study was to evaluate the pain/pressure threshold of selected myofascial points in subjects with chronic mechanical back pain after a single manipulation or mobilization. DESIGN: The study design was a randomized control trial. SETTING: Chiropractic College outpatient clinic. PARTICIPANTS: Thirty subjects aged 18-50 yr (mean age 31 yr, SD = 7 yr) with chronic mechanical low back pain (mean duration of pain 74 months, SD = 83 months) were randomized into two groups. One group received a manipulation and the other received a mobilization. OUTCOME MEASURE: Pain/pressure threshold of selected myofascial points were measured before, immediately after, and 15 and 30 min postintervention. RESULTS: Sixteen patients were allocated to the manipulation group and 14 to the mobilization group. Repeated measured analysis of variance for all locations failed to show clinical or statistical significance (p > .287). The overall effect between treatments and the interaction between treatment and time was not significant (p > .268). CONCLUSION: The absence of significant changes may be attributed to the selection of myofascial points, the instrument sensitivity to small changes, the differences in baseline measures and the absence of effect from one intervention.

The precipitation or aggravation of musculoskeletal pain in patients receiving spinal manipulative therapy.

Complications of chiropractic adjustments or manipulations can be considered either benign or catastrophic. Although there are a number of papers on the more severe complications, the precipitation of benign and often reversible symptoms following chiropractic care has been largely ignored in the literature. This article discusses six cases where pain symptomatology was either aggravated or precipitated at a location other than the presenting complaints. Two potential causes of these complications are discussed: a) the use of long levers, which can exert force on nonsymptomatic joints in the extremities, and b) the manipulation of biomechanically dysfunctional but asymptomatic joints.

The physics of spinal manipulation: work-energy and impulse-momentum principles.

The purpose of this article was to illustrate that the work-energy and impulse-momentum relations are derived from Newton's second law, and, thus, will give identical results to F = ma for any force system analysis. It should be noted that using the work-energy or the impulse-momentum approach requires that all external forces acting on a system are considered. Furthermore, it must be emphasized that any force acting internal to the system (e.g., muscular forces in the system "chiropractor") do not enter these equations.
