According to research using magnetic resonance imaging (MRI), different approaches have been used to estimate cortical functions and some have shown changes in brain function associated with Chiropractic/Osteopathic Joint Manipulation Therapy. Specifically, arterial spin labeling MRI has shown that treatment of somatic dysfunctions leads to cerebral perfusion changes in asymptomatic young participants, while resting state functional connectivity MRI has demonstrated lasting effects on crucial areas of interoceptive networks in patients with low back pain. Other manual therapies such as spinal mobilization, and therapeutic touch / activities have also been shown to have an immediate effect on functional brain connectivity. These findings suggest that the modifications occurring in brain functional circuit organization after a Manipulation can be considered an effective proxy for the neurophysiological changes following manipulative treatments. Additionally, low-frequency fluctuations of the fMRI signal recorded at rest have been shown to influence behavior and contribute to variability in task-evoked responses, revealing networks that span across several cortical areas.
Somatic dysfunction refers to an impairment or dysfunction of the musculoskeletal system, including the bones, muscles, joints, and connective tissues. The term "cerebral perfusion" refers to the flow of blood to the brain, which is essential for the delivery of oxygen and nutrients to brain cells.
The statement "somatic dysfunction leads to cerebral perfusion changes" suggests that problems with the musculoskeletal system can have an impact on blood flow to the brain. This may occur because somatic dysfunction can cause changes in the alignment or movement of the spine, which can in turn affect the blood vessels that supply the brain. Changes in blood flow to the brain can have various effects on brain function and may contribute to the development of neurological symptoms or disorders ie. Lack of attention, decreased concentration, decreased athletic performance, headache, injury prone, hyperactivity, depression, etc.. Over the course of time.
To sum this up. Therapies like Chiropractic/Osteopathic Joint Manipulation Therapy, spinal mobilization, and therapeutic touch/activities have been shown to have immediate effects on functional brain connectivity, as observed through MRI techniques like arterial spin labeling and resting state functional connectivity. These findings suggest that modifications in brain functional circuit organization following manipulative treatments can be considered an effective proxy for neurophysiological changes. Additionally, somatic dysfunction can lead to changes in cerebral perfusion, potentially impacting brain function and contributing to the development of neurological symptoms or disorders.
