In this upcoming episode, Dr. Meier will discuss how people move differently in the presence of (or in anticipation of) pain. Changes in motor control may play an important role in musculoskeletal pain. His lab uses a cross-disciplinary approach that combines neuroscience and movement biomechanics to provide new insights into the role of potential interactions between movement behavior, psychological factors and supraspinal mechanisms in the development and maintenance of persistent low back pain. We’ll touch also on fear avoidance and pain related movement avoidance.  Dr. Michael L. Meier is a senior pain researcher and group leader at the Department of Chiropractic Medicine at the University of Zurich. He received his master’s degree in neuropsychology and his doctorate in cognitive neuroscience from the University of Zurich, focusing on the processing of pain and nociception in the brain. In 2019, he received a grant from the Swiss National Science Foundation (SNF) to study the role of movement behavior and cortical processes in the development and persistence of low back pain. A hallmark of his work is linking research from different disciplines such as biomechanics, neuroscience, and psychology, shedding light on novel interacting pathomechanisms underlying persistent low back pain whose pathoanatomical cause is often unclear.

Dr. Kevin Haussler

Dr. Haussler graduated from The Ohio State University, College of Veterinary Medicine in 1988 and completed a small animal internship in Sacramento, CA.  To further his training in the conservative management of spinal-related disorders, he pursued human training at Palmer College of Chiropractic-West and completed a veterinary chiropractic certification program in 1993.  He attended the University of California-Davis to attain a PhD focusing on spinal pathology and pelvic biomechanics in Thoroughbred racehorses.   Currently, he is an Associate Professor at the Orthopaedic Research Center at Colorado State University and is involved in teaching, clinical duties, and research into the objective assessment of musculoskeletal pain, spinal dysfunction and the application of physical therapy and rehabilitation. Please comment below if you have any questions for us during the interview. I might choose some of them for our conversation.

Subacute and chronic patients with MRI confirmed symptomatic disc herniation treated with spinal manipulation were statistically (and clinically) significantly more likely to report improvement at 3 months compared with the nerve root injection. This prospective cohort study had 104 patients, 52 patients treated with cervical nerve root injection (CNRI) and 52 patients treated with spinal manipulation by a chiropractor. Baseline numerical rating scale (NRS) pain data were collected. Three months after treatment, numerical rating score pain levels were recorded and overall “improvement” was assessed using the Patient Global Impression of Change scale. Responses that were “much better” or “better” were considered to be “improved.” The proportion of patients “improved” was calculated for each treatment method and compared. The NRS and NRS change scores for the 2 groups were compared at baseline and 3 months.  Results showed that there was no significant difference in outcomes between acute patients treated with cervical nerve root blocks and those treated with spinal manipulation at 3 months. However, when comparing the 3-month outcomes for the subacute/chronic patients, more than 78% of patients treated with SMT reported clinically relevant improvement compared with 37.5% of patients receiving a single CNRI. There were no adverse events for patients in either treatment group and the cost of treatment was similar for the 2 treatment procedures.

Spinal manipulation biochemicalSpinal manipulation (SM) can improve function and reduce spinal disability.  SM also provides pain relief for many disorders such as back pain and neck pain.   Pain induces changes in both the central and peripheral nervous systems.  The mechanisms by which SM alters musculoskeletal pain are still not completely known.  Current evidence however suggests that SM is associated with neurophysiological responses including rapid hypoalgesia with simultaneous sympathetic and motor system excitation.  Animal studies have shown that analgesia provided by joint mobilization involves serotonin and noradrenaline receptors in the spinal cord.

A new investigation sought to determine the response of several other biochemical markers of pain and stress to SM.  Specifically, three neuropeptides (neurotensin, oxytocin, orexin A) and a glucorticoid hormone (cortisol) were studied.  The authors note that the neuropeptides have been associated with hypoalgesia and pain modulation and that cortisol plays an analgesic role in the stress response.  Recent theories have suggested that chronic pain could be partially maintained in a facilitated state due to maladaptive responses in the presence of recurrent stressful situations.  To date there is a lack of studies analyzing these specific biomarkers in relation to SM.

The purpose of this study was to determine the effect of cervical or thoracic manipulation on neurotensin (NT), oxytocin, orexin A, and cortisol levels.  Experimenters examined both spinal regions because they thought there may be a difference in anti-nociceptive effect between the cervical spine and thoracic spine.

Participants included graduate students from Spain.  All subjects were asymptomatic and were excluded if there was a contraindication to manipulation, history of whiplash or surgery, pain in the last month, SM in the last 2 months.  Thirty asymptomatic subjects were randomly divided into 3 groups: cervical manipulation (n = 10), thoracic manipulation (n = 10), and non-manipulation (control) (n = 10).  Although it is not explicitly stated in the article, I presume the manipulations were performed by physical therapists since the lead authors were PT’s.  Manipulations consisted of supine ‘anterior’ thoracic spine manipulations, and rotary type cervical manipulations.  Blood samples were extracted before, immediately after, and 2 hours after each intervention by way of venipuncture of the cephalic vein. Neurotensin, oxytocin, and orexin A were determined in plasma using enzyme-linked immuno assay. Cortisol was measured by microparticulate enzyme immuno assay in serum samples.

Results

Neurotensin (NT)

  • Statistically significant increases in neurotensin occurred in both the thoracic and cervical manipulation groups compared to controls post-intervention with the greatest increase occurring immediately following manipulation
  • Cervical spine manipulation produced a slightly larger increase in neurotensin

Orexin A

  • No statistically significant changes were noted in orexin A levels following treatment

Oxytocin

  • Statistically significant increases in oxytocin occurred in both the thoracic and cervical manipulation groups compared to controls post-intervention with the greatest increase occurring immediately following manipulation
  • Cervical spine manipulation produced a significantly larger increase in oxytocin compared to thoracic manipulation

Cortisol

  • A significant increase in cortisol occurred in the cervical manipulation group compared to controls and the thoracic manipulation group immediately post-intervention
  • However, a significant decrease in cortisol was found at 2 hrs post intervention in the thoracic SM group compared with pre-intervention values
  • A non-significant decrease in cortisol was found also found at 2 hrs post intervention in the cervical SM group compared with pre-intervention values


Discussion

NT is an endogenous peptide with broad spectrum of central and peripheral activities, including modulation of pain signal transmission and perception. NT behaves as a neurotransmitter in the brain and as a hormone in the gut.  Because of its association with a wide variety of neurotransmitters, NT has been implicated in the pathophysiology of several CNS disorders such as schizophrenia, drug abuse, Parkinson’s disease (PD), pain, central control of blood pressure, eating disorders, as well as, cancer and inflammation. Note that the antinociceptive effects of NT are independent from opioid antinociception.

Increased oxytocin following SM could be partly responsible for the analgesic effect linked to manual therapy techniques due to the activation of descending pain-inhibitory pathways.

Cortisol is a potent anti-inflammatory that functions to mobilize glucose reserves for energy and modulate inflammation. Ultimately, a prolonged or exaggerated stress response may perpetuate cortisol dysfunction, widespread inflammation, and pain.  SM in this study led to an immediate increase in cortisol followed by a significant 2 hour decrease in levels with thoracic manipulation and a decrease in 2 hr levels with cervical manipulation.


Key Points

  • SM can modify several biochemical markers of pain and stress
  • These findings suggest that descending inhibitory pathway mechanisms may be involved in the physiological effects that follow SM
  • The effect size for the cervical manipulation group was larger than that for the thoracic manipulation group suggesting an increase in the activation of the possible descending inhibitory pathway mechanisms after cervical manipulation compared to thoracic manipulation

18448850_xxlThe application of spinal manipulative therapy (SMT) is a cost-effective and widely recognized manual intervention used by a variety of health care professionals in the management of musculoskeletal pain. A growing body of scientific evidence supports the use of SMT for the treatment of a broad range of musculoskeletal disorders citing short-term antinociceptive (pain-relieving) effects and restoration of normal joint mechanics.

Last year, about this time, I wrote about a systematic review that found spinal manipulation therapy (SMT) has a pain reducing effect as measured by pressure pain thresholds (PPT).  Additionally, the effect of SMT on pain reduction was statistically significant at remote locations (for example, adjusting the neck yielded reduction in pain at the elbow).

A new study has emerged in the scientific literature that advances our understanding of the topic (Srbely et al, 2013).  The authors note that although the pathophysiology of myofascial pain syndrome (MPS) is still unclear, research suggests that myofascial trigger points (MTPs) play an fundamental role in the generation and clinical manifestation of MPS.  However, it is currently unknown if the antinociceptive effects of SMT in myofascial tissues are manifest predominantly via regional or general mechanisms, or a combination of both. A study was needed to specifically investigate the hypothesis that SMT evokes robust antinociceptive effects in MTPs preferentially located within neurosegmentally linked myofascial tissues.

Srbely et al conducted the study through the University of Guelph.  The study was a single session, single blinded, randomized controlled intervention.  The primary inclusion criterion was the presence of a clinically identifiable MTP locus (active or latent) within the right infraspinatus and right gluteus medius muscles.  The primary diagnostic criterion used to clinically identify the trigger point locus was ‘a palpable hyperirritable nodule nested within a taut band of skeletal muscle; sustained ischemic pressure over the trigger point locus elicited a dull achy regional pain or discomfort.’  Exclusion criteria encompassed conditions that would affect normal somatosensory processing.

Thirty-six participants qualified for the study and were randomly assigned to test or control groups.  Two chiropractors saw participants at an urban outpatient clinic. One chiropractor performed the history, exam and manipulations while the other chiropractor (blinded to treatment allocation) detected the trigger points and measured all PPTs. The primary outcome was PPT values from infraspinatus and gluteus medius muscles.  The infraspinatus was chosen due to its innervation from the manipulated segment (C5-6). The gluteus medius acted as a regional control point (L4-S1 innervation).

PPT was measured with a force gauge (Newtons) over the trigger point locus (infraspinatus, gluteus medius) and was defined as the force necessary to elicit the onset of a deep dull achy local discomfort and/or referred pain. Measurements were taken at 1,5, 10, and 15 minutes postintervention.  In order to specifically compare regional antinociceptive effects between intervention groups, the authors also calculated the PPT difference (PPTdiff) between infraspinatus and gluteus medius trigger points at each time interval within each participant. Participants received a rotary type manipulation to the C5-6 segment in a supine posture.   Additionally, a drop piece mechanism was used to aid in the high velocity low amplitude thrust.  Control participants received a sham manipulation.  The sham consisted of rotating the neck of the participant, supporting the neck of the participant with the clinician’s forearm under the headpiece and a thrust of the forearm into the headpiece.  It is noted that the contact hand did not thrust and did not create ‘a real manipulation’ of any segment.

Results:

  • there was a significantly increased PPT threshold for infraspinatus trigger points in treated participants compared to controls at all time intervals beyond baseline
  • there was a significantly increased PPT threshold for infraspinatus compared to gluteus medius before and after manipulation at all time intervals beyond baseline
  • no significant differences in PPT scores were observed at any time interval when comparing test gluteus medius, control infraspinatus, and control gluteus medius groups
  • there were significant increases in PPTdiff in the test group vs controls at all time intervals beyond baseline

Key Findings:

  • This study suggests that SMT evokes statistically significant short-term increases in PPT in segmentally related myofascial tissues in young adults
  • Decreased pressure sensitivity (increased PPT score) was observed at all time intervals beyond baseline within neurologically linked infraspinatus muscle after real, but not sham, manipulation
  • The peak antinociceptive effect was measured as a 36% decrease in pressure sensitivity from baseline values and was recorded at 5 minutes postSMT

So, what does this study tell us?  It suggests that SMT evokes robust regional antinociceptive effects in myofascial tissues.  It also provides important evidence to support further research into the potential benefit and role of SMT in the management of chronic widespread pain syndromes  including myofascial pain, and fibromyalgia.

Dr. Carlos Gevers

Dr. Carlos Gevers joins me to discuss mechanisms of spinal manipulation, particularly as they relate to central sensitization and neuroinflammation. He also shares a study on Tumor Necrosis Factor-Alpha in Urine Samples of Patients With Chronic Low Back Pain Undergoing Chiropractic Care.

Carlos Gevers Montoro is a second-generation chiropractor. He graduated from Life Chiropractic College West in 2003 as Valedictorian and the recipient of the Clinical Excellence Citation award. After practicing for a few years in Spain and France, he was instrumental in the opening of the Madrid College of Chiropractic (MCC), where he still lectures. His contributions at the MCC were mostly related to the clinical sciences. In parallel, he served for seven years as the President of the Spanish Chiropractic Association, being involved in chiropractic politics and policy at the national and international level.

In 2018 he decided to switch gears and take a completely new path in the research arena. He started his PhD in Pain Neurosciences at UQTR – University of Montreal joint program under the supervision of Prof. Mathieu Piché. His PhD studies are partially funded, by a prestigious grant from the Government of Quebec. His line of research and his first publications are mostly focused on mechanisms of spinal manipulation, particularly as they relate to central sensitization and neuroinflammation. These two phenomena seem to be strongly implicated in the development of chronic pain syndrome and other conditions.

Dr. Ken Weber

Dr. Ken Weber and I discuss his research pursuits which involve: 1) developing imaging modalities that are more sensitive and specific to the pathology, providing more diagnostic, prognostic, and predictive information; 2) providing more quantitative information to the clinician; and 3) using these measures to better understand the nervous system and how it functions, the neurophysiology of pain, how treatments work, and why certain treatments work for some patients but not for others. Dr. Ken Weber is an Instructor in the Department of Anesthesia, Perioperative and Pain Medicine at Stanford University. He obtained his Doctor of Chiropractic from Palmer College of Chiropractic Florida in 2009 and then completed a PhD in neuroscience at Northwestern University in 2016, specializing in movement and rehabilitation science. Ken’s research intersects clinical pain research and advanced MRI techniques with an emphasis on brain, spinal cord, and musculoskeletal imaging. His research aims to better understand the neural and musculoskeletal changes underlying clinical pain conditions, the mechanisms of treatments, and predictors for recovery. Ken is currently supported by a K23 Mentored Patient-Oriented Research Career Development Award from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health. His previous funding has included the National Center for Complementary and Integrative Health, the National Institute on Drug Abuse, and the NCMIC Foundation, Inc.

Dr. Craig Moore, Chiropractic, HeadachesDr. Craig Moore discusses the role of chiropractors in the management of headaches. Some areas of discussion we touch upon include the societal impact and costs associated with headaches; prevalence of headaches in the community; prevalence of headache in chiropractic clinical settings; why do people turn to chiropractors; current level of evidence for chiropractic treatment of different headache types; what do the headache guidelines recommend for each headache; what should a chiropractor consider when examining a headache patient (history and examination).

Dr. Craig Moore is the director of a multi-disciplinary allied-health clinic in Crows Nest, Sydney. His clinic focus is toward the diagnosis and management of musculoskeletal disorders and in headache disorders in particular (migraine, tension-type headache, cervicogenic headache).

Dr. Moore has completed a Masters of Clinical Trials Research and is currently enrolled at the University of Technology Sydney, doing a PhD in Public Health – focused on the chiropractic management of headache disorders. As a founding member of the Australian Chiropractic Research Network (ACORN) he has a strong interest in supporting the development of chiropractic research through the utilization of this practice-based research network project. He has numerous publications in the scientific literature in such journals as Spine, BMC Neurology, JMPT, BMC Musculoskeletal Disorders and Headache to name a few. Dr. Moore is also a CARL Fellow!
