ReviewMuscle activity pattern dependent pain development and alleviation.
Muscle activity is for decades considered to provide health benefits irrespectively of the muscle activity pattern performed and whether it is during e.g. sports, transportation, or occupational work tasks. Accordingly, the international recommendations for public health-promoting physical activity do not distinguish between occupational and leisure time physical activity. However, in this body of literature, attention has not been paid to the extensive documentation on occupational physical activity imposing a risk of impairment of health - in particular musculoskeletal health in terms of muscle pain. ⋯ Of note is that intensive muscle strength training actually may rehabilitate painful muscles, which has recently been repeatedly proven in randomized controlled trials. With training the maximal muscle activation and strength can be shown to recover, and consequently allow for decreased relative muscle load during occupational repetitive work tasks. Exercise training induces adaptation of metabolic and stress-related mRNA and protein responses in the painful muscles, which is in contrast to the responses evoked during repetitive work tasks per se.

Review Meta AnalysisEpidemiology: spinal manipulation utilization.
The objectives of this article are to (1) describe spinal manipulation use by time, place, and person, and (2) identify predictors of the use of spinal manipulation. We conducted a systematic review of the English-language literature published from January 1, 1980 through June 30, 2011. Of 822 citations identified, 213 were deemed potentially relevant; 75 were included after further consideration. ⋯ Back and neck pain are the most frequent indications for receiving spinal manipulation; non-musculoskeletal conditions comprise a very small percentage of indications. Although spinal manipulation is more commonly used in adults than children, evidence suggests that spinal manipulation may be more likely used for non-musculoskeletal ailments in children than in adults. Patient satisfaction with spinal manipulation is very high.

ReviewThe basis for spinal manipulation: chiropractic perspective of indications and theory.
It is reasonable to think that patients responding to spinal manipulation (SM), a mechanically based therapy, would have mechanical derangement of the spine as a critical causal component in the mechanism of their condition. Consequently, SM practitioners routinely assess intervertebral motion, and treat patients on the basis of those assessments. ⋯ This paper reviews the putative mechanical features of the subluxation and three theories that form the foundation for much of chiropractic practice. It concludes with discussion of subluxation as an indicator for SM therapy, particularly from the perspective that subluxation may be one contributory cause of ill-health within a "web of causation".

Review Meta AnalysisChanges in pain sensitivity following spinal manipulation: a systematic review and meta-analysis.
Spinal manipulation (SMT) is commonly used for treating individuals experiencing musculoskeletal pain. The mechanisms of SMT remain unclear; however, pain sensitivity testing may provide insight into these mechanisms. The purpose of this systematic review is to examine the literature on the hypoalgesic effects of SMT on pain sensitivity measures and to quantify these effects using meta-analysis. ⋯ SMT demonstrated a favorable effect over other interventions on increasing PPT. Subgroup analysis showed a significant effect of SMT on increasing PPT at the remote sites of stimulus application supporting a potential central nervous system mechanism. Future studies of SMT related hypoalgesia should include multiple experimental stimuli and test at multiple anatomical sites.
