Reliability of zygapophysial joint space measurements made from magnetic resonance imaging scans of acute low back pain subjects: comparison of 2 statistical methods.
This purpose of this study was to assess the reliability of measurements made of the zygapophysial (Z) joint space from the magnetic resonance imaging scans of subjects with acute low back pain using new equipment and 2 different methods of statistical analysis. If found to be reliable, the methods of Z joint measurement can be applied to scans taken before and after spinal manipulation in a larger study of acute low back pain subjects. ⋯ Both statistical methods were found to be useful and complementary and showed the measurements to be highly reliable.

Mechanical vs manual manipulation for low back pain: an observational cohort study.
This is an observational prospective cohort study to explore the treatment effect of mechanical vs manual manipulation for acute low back pain. ⋯ This study highlights the challenges inherent with conducting research that allows for "treatment as usual." The data and experience derived from this investigational study will be used to design a future randomized clinical trial in which tighter controls will be imposed on the treatment protocol.

Randomized Controlled TrialThe effect of spinal manipulation on the efficacy of a rehabilitation protocol for patients with chronic neck pain: a pilot study.
This pilot study sought to (1) determine whether a 4-week period of chiropractic care improved the ability of chronic neck pain patients to respond to an 8-week period of exercise rehabilitation and (2) determine effect sizes to use in sample size calculations for future studies. ⋯ Chiropractic care combined with exercise and exercise alone are both effective at reducing functional disability and pain in chronic nonspecific neck pain patients. Future studies will need at least 64 subjects per group to determine if there are differences between the groups and if these differences are attributable to changes in neuromuscular measures.
