Outcome Measures

Primary Outcomes (12)

  • Functional near-infrared spectroscopy (fNIRS)

    Functional near-infrared spectroscopy (fNIRS) is an optical imaging tool for noninvasive, continuous monitoring of regional blood flow and tissue oxygenation. It can measure two hemodynamic parameters, both deoxyhemoglobin (HHb) and oxyhemoglobin (HbO2), at the same time. It reflects changes in regional blood flow to areas of the brain involved in processing functional tasks (Cognitive tasks). A baseline assessment of a participant will be done before the start of the intervention.

    Aftwe 16 weeks of intervention

  • Heart rate variability (HRV)

    HRV will be used as an objective assessment of psychological health and stress for the participants. High HRV is a marker of an adaptable, responsive nervous system that can detect sensory stimuli and appropriately increase or decrease the heart rate based on the needs of the individual Low HRV and low parasympathetic activity is associated with chronic pain states, poor cardiovascular health and mood disorders.

    Up to 16 weeks

  • Serum Brain-derived neurotrophic factor (BDNF)

    Brain-derived neurotrophic factor (BDNF) plays an important role in neuronal survival and growth, serves as a neurotransmitter modulator, and participates in neuronal plasticity, essential for learning and memory. The higher concentration shows more activity. A baseline assessment of a participant will be done before the start of the intervention.

  • Whole head EEG( sub-cohort of participants)

    The EEG will be recorded from 40-scalp electrodes using the extended 10-20 system montage (Quick-Cap International). The participant will be seated comfortably in a chair with eyes closed throughout the entire recording. We will record a period of resting whole head EEG. We will use standardized low-resolution brain electromagnetic tomography (sLORETA) for the resting EEG to calculate potential changes (Spatio-spectral Analysis) in brain activity and communication post the chiropractic care intervention. A baseline assessment of a participant will be done before the start of the intervention.

EXPERIMENTAL

A registered chiropractor will assess the entire spine, and both sacroiliac joints will be assessed for vertebral subluxation by a registered chiropractor with at least five years of clinical experience.The clinical indicators that will be used to assess the function of the spine before spinal adjustment intervention include assessing for joint tenderness to palpation manually palpating for a restricted intersegmental range of motion, assessing for palpable asymmetric intervertebral muscle tension, and any abnormal or blocked joint play and end-feel of the joints. Chiropractors use these biomechanical characteristics as clinical indicators of spinal dysfunction and vertebral subluxation.

Other: Chiropractic Care

Control Group

PLACEBO COMPARATOR

The participants head and/or spine will be moved in ways that include passive and active movements, similar to what is done when assessing the spine by a chiropractor. The control intervention will also include the participants moving into adjustment setup positions similar to how the chiropractor would typically set up a patient with no joint pre-loading or adjustive thrust. No spinal adjustment will be performed during any control intervention. This control intervention is not intended to act as a sham treatment session

Other: Control Group

Interventions

The actual force applied to the patient's spine depends on the chiropractor, the patient, and the spinal location of the subluxation, the general shape of the force-time history of spinal adjustments is very consistent and the duration of the thrust is always less than 200 milliseconds.
