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.

Prevalence of modic changes in active duty military men with lumbar disk herniation who were scheduled for surgery.
The purpose of this study was to report on the prevalence of Modic changes (MCs) in a group of Netherlands military men who were scheduled for surgery (lumbar discectomy). ⋯ For the subjects in this study, MCs were most common at the lower lumbar spine segments, with a predominance of type II. In this study, the presence of a disk herniation and MC at the same level was 37.7%; however, a significant association was not demonstrable.

Modulation of pain-induced neuromuscular trunk responses by pain expectations: a single group study.
The purpose of this study was to investigate the alteration of pain-induced neuromuscular trunk responses by expectations in healthy volunteers. ⋯ These results confirm previous findings and indicate that experimental pain can alter neuromuscular responses during a trunk flexion-extension task. Furthermore, this study suggests that expectations can alter some of these alterations. Future studies should determine whether neuromuscular changes induced by expectations may contribute to the transition from acute to chronic low-back pain.

Comparative StudyMyofascial trigger points, pain, disability, and sleep quality in individuals with mechanical neck pain.
The purpose of this study was to investigate the presence of active myofascial trigger points (MTrPs) in a greater number of muscles than previous studies and the relation between the presence of MTrPs, the intensity of pain, disability, and sleep quality in mechanical neck pain. ⋯ The referred pain elicited by active MTrPs in the neck and shoulder muscles contributed to symptoms in mechanical neck pain. Patients exhibited higher disability and worse sleep quality than controls. Sleep quality was associated with pain intensity and disability. No association between active MTrPs and the intensity of pain, disability, or sleep quality was found.
