Spinal Manipulative Therapy Has an Immediate Effect on Thermal Pain Sensitivity in People With Low Back Pain

Chiro.Org Blog: Inhibition of A-delta fiber-mediated pain perception was similar for all groups. However, inhibition of temporal summation was observed only in participants receiving SMT, suggesting a modulation of dorsal horn excitability that was observed primarily in the lumbar innervated area. […]

Effects of 12 Weeks of Chiropractic Care on Central Integration of Dual Somatosensory Input in Chronic Pain Patients

Chiro.Org Blog: The dual SEP ratio technique appears to be sensitive enough to measure changes in cortical intrinsic inhibitory interactions in patients with chronic neck pain. The observations in 6 subjects revealed that 12 weeks of chiropractic care improved suppression of SEPs evoked by dual upper limb nerve stimulation at the level of the motor cortex, premotor areas, and/or subcortical areas such as basal ganglia and/or thalamus. It is possible that these findings explain one of the mechanisms by which chiropractic care improves function and reduces pain for chronic pain patients. […]

Metabolic Syndrome Components Are Associated with Intervertebral Disc Degeneration

Chiro.Org Blog: Metabolic Syndrome (MS) components were significantly associated with thoracic intervertebral disc degeneration (DD). Furthermore, accumulation of MS components significantly increased the odds ratio for thoracic DD. These findings support the need for further studies of the effects of metabolic abnormality on disc degeneration. […]

The Physiological Role of Tumor Necrosis Factor in Human Immunity and Its Potential Implications in Spinal Manipulative Therapy

Chiro.Org Blog: Physiological roles of tumor necrosis factor (TNF) have recently regained attention in the biomedical research community; new findings, particularly with the discovery of the interaction between TNF and Tregs, offer new insights to understanding human immunophysiology. This progress may provide a new paradigm in understanding SMT. […]

Visceral Responses to Spinal Manipulation

Chiro.Org Blog: Spinal manipulation is generally accepted as one reasonable treatment option in the management of musculoskeletal disorders such as low back pain and neck pain. Some evidence also exists that certain visceral disorders benefit from spinal manipulation (for example, see Bakris et al., 2007). However, the mechanisms by which spinal manipulation might alter visceral function, and so impact visceral disease, remain unclear. Therefore, in this paper, we review the currently available literature concerning visceral responses to the application of mechanical stimuli to the spine and paraspinal tissues. […]

The OUCH Randomized Controlled Trial of Adverse Events

Chiro.Org Blog: A substantial proportion of adverse events after chiropractic treatment may result from natural history variation and nonspecific effects. […]

Altered Central Integration of Dual Somatosensory InputAfter Cervical Spine Manipulation

Chiro.Org Blog: This study suggests that cervical spine manipulation may alter cortical integration of dual somatosensory input. These findings may help to elucidate the mechanisms responsible for the effective relief of pain and restoration of functional ability documented after spinal manipulation treatment. […]

Do Participants With Low Back Pain Who Respond to Spinal Manipulative Therapy Differ Biomechanically?

Chiro.Org Blog: After the first SMT, SMT responders displayed statistically significant decreases in spinal stiffness and increases in multifidus thickness ratio sustained for more than 7 days; these findings were not observed in other groups. Similarly, only SMT responders displayed significant post-SMT improvement in apparent diffusion coefficients. […]

Effects of Acupuncture, Cervical Manipulation and NSAID therapy on Dizziness and Impaired Head Repositioning of Suspected Cervical Origin

Chiro.Org Blog: In a single-subject experiment undertaken on 14 consecutive patients, the effects of acupuncture, cervical manipulation, no therapy, and NSAID-percutan application on kinesthetic sensibility, dizziness/vertigo and pain were studied in patients with dizziness/vertigo of suspected cervical origin. […]

Efficacy of Manual and Manipulative Therapy in the Perception of Pain and Cervical Motion in Patients with Tension-type Headache: A Randomized, Controlled Clinical Trial

Chiro.Org Blog: All 3 treatment groups showed significant improvements in the different dimensions of pain perception. Manual therapy and manipulative treatment improved some cervical ranges of motion. Headache frequency was reduced with manipulative treatment (P < .008). Combined treatment reported improvement after the treatment (P < .000) and at follow-up (P < .002). Pain intensity improved after the treatment and at follow-up with manipulative therapy (P < .01) and combined treatment (P < .01). […]

Spinal Manipulative Therapy and Somatosensory Activation

Chiro.Org Blog: The goal of this article is to briefly update our knowledge regarding several physical characteristics of an applied SMT, and review what is known about the signaling characteristics of sensory neurons innervating the vertebral column in response to spinal manipulation. Based upon the experimental literature, we propose that SMT may produce a sustained change in the synaptic efficacy of central neurons by evoking a high frequency, bursting discharge from several types of dynamically-sensitive, mechanosensitive paraspinal primary afferent neurons. […]

Spinal Pain in Adolescents

Chiro.Org Blog: Neck, mid back, and low back pain are common at the age of 11–15 years. For the majority of the participants, the pain seems to be mild in nature, relatively infrequent and of low intensity. A group of 14-20% was more severely affected with frequent pain which was also more intense. The two-year course showed a progressive development in pain, and that pain was likely to spread to more locations over a two-year period, regardless of initial pain location. […]

Manual Therapy Followed by Specific Active Exercises

Chiro.Org Blog: The present study confirms the immediate analgesic effect of manual therapy for chronic non specific Low Back Pain. Followed by specific active exercises, it reduces significantly functional disability and tends to induce a larger decrease in pain intensity, compared to a control group. However, these results of our pilot study need to be confirmed by future studies with appropriate sample sizes. […]

Tissue Damage Markers After a Spinal Manipulation in Healthy Subjects

Chiro.Org Blog: Tissue damage markers creatine phosphokinase (CPK), lactate dehydrogenase (LDH), C-reactive protein (CRP), troponin-I, myoglobin, neuron-specific enolase (NSE), and aldolase were determined in samples. Statistical analysis was performed through a 3 × 3 mixed-model ANOVA. Neither cervical manipulation nor thoracic manipulation did produce significant changes in the CPK, LDH, CRP, troponin-I, myoglobin, NSE, or aldolase blood levels. Our data suggest that the mechanical strain produced by SM seems to be innocuous to the joints and surrounding tissues in healthy subjects. […]

Review Of Methods Used By Chiropractors To Determine The Site For Applying Manipulation

Chiro.Org Blog: A considerable range of methods is in use for determining where in the spine to administer spinal manipulation. The currently published evidence falls across a spectrum ranging from strongly favourable to strongly unfavourable in regard to using these methods. In general, the stronger and more favourable evidence is for those procedures which take a direct measure of the presumptive site of care- methods involving pain provocation upon palpation or localized tissue examination. Procedures which involve some indirect assessment for identifying the manipulable lesion of the spine-such as skin conductance or thermography-tend not to be supported by the available evidence. […]
