the effects of chiropractic Spinal manipulation on central processing of tonic pain a pilot study using standardized low resolution brain electromagnetic tomography sloreta
Scientific Reports, 2019Co-Authors: Kelly Holt, Muhammad Samran Navid, Dina Lelic, Imran Khan Niazi, Esben Bolvig Mark, Asbjorn Mohr Drewes, Heidi HaavikAbstract:The objectives of the study were to investigate changes in pain perception and neural activity during tonic pain due to altered sensory input from the spine following chiropractic Spinal Adjustments. Fifteen participants with subclinical pain (recurrent Spinal dysfunction such as mild pain, ache or stiffness but with no pain on the day of the experiment) participated in this randomized cross-over study involving a chiropractic Spinal Adjustment and a sham session, separated by 4.0 ± 4.2 days. Before and after each intervention, 61-channel electroencephalography (EEG) was recorded at rest and during 80 seconds of tonic pain evoked by the cold-pressor test (left hand immersed in 2 °C water). Participants rated the pain and unpleasantness to the cold-pressor test on two separate numerical rating scales. To study brain sources, sLORETA was performed on four EEG frequency bands: delta (1–4 Hz), theta (4–8 Hz), alpha (8–12 Hz) and beta (12–32 Hz). The pain scores decreased by 9% after the sham intervention (p < 0.05), whereas the unpleasantness scores decreased by 7% after both interventions (p < 0.05). sLORETA showed decreased brain activity following tonic pain in all frequency bands after the sham intervention, whereas no change in activity was seen after the chiropractic Spinal Adjustment session. This study showed habituation to pain following the sham intervention, with no habituation occurring following the chiropractic intervention. This suggests that the chiropractic Spinal Adjustments may alter central processing of pain and unpleasantness.

preretinal hemorrhages following chiropractor neck manipulation
American Journal of Ophthalmology Case Reports, 2018Co-Authors: Yannis M. Paulus, Nicholas BelillAbstract:Abstract Purpose To report a case of a new complication following complementary and alternative medicine chiropractor neck manipulation with multiple preretinal hemorrhages. Observations A 59-year-old Caucasian female presented with the acute, painless constant appearance of 3 spots in her vision immediately after a chiropractor performed cervical Spinal manipulation using the high-velocity, low-amplitude technique. Examination multiple unilateral preretinal hemorrhages with no retinal tears. The preretinal hemorrhages were self-limited and resolved by 2 months later. Conclusions Chiropractor neck manipulation has previously been reported leading to complications related to the carotid artery and arterial plaques. This presents the first case of multiple unilateral preretinal hemorrhages immediately following chiropractic neck manipulation. This suggests that chiropractor Spinal Adjustment can not only affect the carotid artery, but also could lead to preretinal hemorrhages.

reflex effects of a Spinal Adjustment on blood pressure
Chiropractic Journal of Australia, 2010Co-Authors: Kelly Holt, Randy W Beck, Stephen Sexton, Heidi Haavik TaylorAbstract:Objective: To investigate whether an Adjustment to any segment in the spine resulted in a blood pressure change and to see whether the direction of any potential blood pressure changes were dependent on the region of the spine adjusted. Methods: Participants included 70 patients attending the New Zealand College of Chiropractic Student Health Centre. Blood pressure was recorded by a blinded examiner before and after either a single Diversified type chiropractic Adjustment or an Adjustment set-up with no thrust. Participants were randomly allocated to groups. Each trial was allocated to a subgroup based on the Spinal region involved. Some participants were involved in more than one trial session with a total of 118 trials included in the study. Results: Multifactorial repeated measures ANOVA assessing for any effect from the Adjustment revealed a significant overall interactive effect for the factors TIME (pre / post) and GROUP (Adjustment / control) [F (1,103)=4.23, p=0.042] for systolic blood pressure. Further analysis of the Adjustment group revealed a significant overall effect [F (1,49)=10.89, p=0.002] with systolic blood pressure decreasing significantly (-3.9 +/- 10.3mmHg) following an Adjustment. No other significant differences were found in the Adjustment or control groups. Conclusion: An Adjustment to any segment in the spine resulted in a statistically significant average decrease in systolic blood pressure of 3.9 mmHg. The direction of blood pressure change that was observed was not dependent on the region of the spine adjusted. However, visual analysis suggests cervical and lumbopelvic Adjustments had a greater influence on systolic blood pressure than thoracic Adjustments. Diastolic blood pressure remained relatively constant. Average changes in blood pressure were unlikely to be clinically significant. However, in individual participants some blood pressure changes were considered to be clinically relevant following an Adjustment.
