Randomized Controlled Trial Comparative StudyQuantification of cavitation and gapping of lumbar zygapophyseal joints during spinal manipulative therapy.
The purpose of this study was to use previously validated methods to quantify and relate 2 phenomena associated with chiropractic spinal manipulative therapy (SMT): (1) cavitation and (2) the simultaneous gapping (separation) of the lumbar zygapophyseal (Z) joint spaces. ⋯ Zygapophyseal joints receiving chiropractic SMT gapped more than those receiving SPP alone; Z joints of men gapped more than those of women, and cavitation indicated that a joint had gapped but not how much a joint had gapped.

Randomized Controlled Trial Comparative StudyChanges in pressure pain thresholds and Basal electromyographic activity after instrument-assisted spinal manipulative therapy in asymptomatic participants: a randomized, controlled trial.
The purpose of this study was to investigate the effects of instrument-assisted spinal manipulative therapy (SMT) targeted to the low-back region on changes in pressure pain thresholds (PPTs) and basal electromyographic activity (BEA) in asymptomatic participants. ⋯ The application of instrument-assisted SMT resulted in an immediate and widespread hypoalgesic effect with local muscle relaxation in asymptomatic participants. It is hypothesized that therapeutic mechanisms, either segmental or central, may be involved in the therapeutic effects of instrument-assisted SMT.

Randomized Controlled TrialA randomized clinical trial of chiropractic treatment and self-management in patients with acute musculoskeletal chest pain: 1-year follow-up.
We have previously reported short-term follow-up from a pragmatic randomized clinical trial comparing 2 treatments for acute musculoskeletal chest pain: (1) chiropractic treatment and (2) self-management. Results indicated a positive effect in favor of the chiropractic treatment after 4 and 12 weeks. The current article investigates the hypothesis that the advantage observed at 4 and 12 weeks would be sustained after 1 year. In addition, we describe self-reported consequences of acute musculoskeletal chest pain at 1-year follow-up. ⋯ At the 1-year follow-up, we found no difference between groups in terms of pain intensity and self-perceived change in chest pain in the first randomized clinical trial assessing chiropractic treatment vs minimal intervention for patients with acute musculoskeletal chest pain. Further research into health care utilization and use of prescriptive medication is warranted.

Randomized Controlled TrialInvestigation of the effects of a centrally applied lumbar sustained natural apophyseal glide mobilization on lower limb sympathetic nervous system activity in asymptomatic subjects.
The purpose of this study was to investigate the effects of a manual mobilization technique on indirect measures of sympathetic nervous system activity. ⋯ The results of this study showed that, in asymptomatic participants, both lumbar SNAG and sham techniques performed on L4/5 intervertebral joint with active flexion induced a sympathoexcitatory response in lower limbs compared with the control group.

Randomized Controlled Trial Comparative StudyEffects of muscular stretching and segmental stabilization on functional disability and pain in patients with chronic low back pain: a randomized, controlled trial.
The purpose of this study was to compare the effects of 2 exercise programs, segmental stabilization exercises (SSEs) and stretching of trunk and hamstrings muscles, on functional disability, pain, and activation of the transversus abdominis muscle (TrA), in individuals with chronic low back pain. ⋯ Both techniques improved pain and reduced disability. In this study, SS was superior to muscular stretching for the measured variables associated with chronic low back pain.
