Chiropractic care is increasingly recognised for its neurological benefits, extending beyond pain relief to support brain-body communication, coordination, and functional performance. In 2012, Dr. Heidi Haavik and Dr. Brian Murphy published a study investigating how spinal manipulation affects sensorimotor integration and motor control. This research provided detailed insights into the mechanisms by which spinal adjustments influence the nervous system, highlighting the broader role of chiropractic care in optimising neurological function.
Dr. Haavik, a chiropractor and neurophysiologist, has dedicated her career to exploring the relationship between spinal function and the nervous system. Her work emphasises that spinal adjustments influence cortical and spinal processes, improving movement efficiency, coordination, and overall nervous system performance.
Let's Summarise the study: "The role of spinal manipulation in addressing disordered sensorimotor integration and altered motor control"
Why the Study Was Done
Previous research by Haavik and Murphy had shown that spinal adjustments can alter sensorimotor integration and improve proprioception. However, much of this research focused on isolated aspects of neurological function, such as cortical excitability or joint position sense. The 2012 study aimed to provide a comprehensive understanding of how spinal manipulation influences both sensorimotor integration and motor control simultaneously.
The researchers were particularly interested in exploring subclinical dysfunction, where spinal segments may not produce pain but still disrupt nervous system communication. By examining these effects, the study sought to demonstrate that chiropractic care can improve functional performance even in individuals without overt symptoms, supporting a broader preventive and optimisation role for spinal care.
How the Study Was Done
The study recruited participants with either subclinical spinal dysfunction or mild musculoskeletal discomfort, ensuring that the findings would reflect changes in nervous system function rather than responses to acute injury. Participants underwent a series of neurophysiological assessments both before and after receiving spinal adjustments.
Chiropractors performed precise manipulations of dysfunctional spinal segments. Adjustments targeted areas identified through clinical assessment as having altered mobility or joint mechanics. The manipulations aimed to restore normal spinal function and reduce interference in nervous system communication.
To evaluate outcomes, the researchers measured sensorimotor integration using somatosensory evoked potentials (SEPs) and assessed motor control through electromyography (EMG) and coordinated movement tasks. These measures allowed the researchers to determine how spinal adjustments influence both sensory processing and the execution of precise motor tasks.
The study design enabled the researchers to observe immediate neurological effects of spinal manipulation, providing objective evidence of how adjustments impact the nervous system.
What the Study Found
The results demonstrated that spinal manipulation improved sensorimotor integration, meaning the brain became more efficient at processing sensory input from the body. SEPs indicated enhanced transmission of sensory signals, suggesting that adjustments help the nervous system communicate more effectively with muscles and joints.
Motor control also improved following the adjustments. EMG recordings showed more coordinated muscle activation patterns, and participants performed movement tasks with greater accuracy and precision. These findings highlight that spinal adjustments do more than alleviate pain—they optimise the nervous system’s ability to control movement.
The study also reinforced the importance of addressing subclinical dysfunction. Participants without significant pain still experienced measurable improvements in sensorimotor function and motor control after spinal adjustments, demonstrating that chiropractic care can provide functional benefits beyond symptomatic relief.
What This Means
In everyday terms, this study shows that spinal adjustments can help your body move more efficiently and respond to sensory input more accurately. Improved coordination, balance, and precision in movement are all outcomes of enhanced brain-body communication. Even if you do not experience pain, chiropractic care can help your nervous system function optimally, supporting everyday activities and overall wellbeing.
Why The Study: "The role of spinal manipulation in addressing disordered sensorimotor integration and altered motor control" Matters For Chiropractic Care
This study has significant implications for chiropractic practice. Chiropractors can approach spinal dysfunction not only as a mechanical issue but also as a factor that affects neurological function and motor control. By addressing suboptimal spinal segments, adjustments can enhance sensorimotor integration, improve coordination, and optimise functional performance.
For patients, the research demonstrates that chiropractic care has preventive and performance-enhancing benefits. Improvements in movement efficiency, posture, and balance can reduce the risk of injury, support athletic performance, and contribute to long-term health. Regular chiropractic assessments and adjustments can maintain nervous system function, even in individuals who are not experiencing pain.
What This Means
Even if you feel healthy and are not in pain, chiropractic care can help your body and brain work together more effectively. Your movements can become smoother, your balance more stable, and your coordination more precise, supporting everyday activities and reducing the risk of minor injuries.
How This Study Connects to Broader Research
The 2012 study builds on previous work by Haavik and Murphy from 2007, 2008, and 2011, demonstrating that spinal adjustments influence sensorimotor integration, proprioception, and motor control. Together, these studies provide a detailed picture of how chiropractic care affects the nervous system at both cortical and spinal levels.
The research also aligns with broader findings in neurophysiology, showing that optimising spinal function can influence reflexes, cortical excitability, and neuroplasticity. Collectively, this body of work supports the concept that chiropractic care is not only for pain relief but also for maintaining and enhancing neurological and functional performance.
What This Means
Chiropractic care is backed by research showing that spinal adjustments can improve how your brain and body communicate, enhancing movement control and overall function. This reinforces chiropractic care as a proactive approach to maintaining health and optimising neurological performance.
Looking Ahead
Future research may explore the long-term effects of regular chiropractic care on sensorimotor integration and motor control. Questions remain regarding the optimal frequency and type of adjustments for maximising neurological benefits and how these effects manifest in different populations, including children, older adults, or individuals with subtle spinal dysfunction.
Advances in neurophysiological measurement techniques will continue to provide insight into how spinal adjustments influence nervous system function. As research progresses, chiropractors will be able to apply increasingly precise, evidence-based strategies to optimise patient outcomes, both for those experiencing symptoms and those seeking preventive care.
What This Means
Ongoing research helps explain why chiropractic care can benefit people even in the absence of pain. Adjustments may support better coordination, posture, balance, and overall neurological health, highlighting the value of chiropractic care as both a treatment and preventive measure.
The 2012 study by Dr. Heidi Haavik and Dr. Brian Murphy demonstrated that spinal manipulation positively influences sensorimotor integration and motor control. By improving the nervous system’s ability to process sensory information and coordinate movement, chiropractic adjustments can enhance posture, balance, coordination, and overall functional performance.
For chiropractors, the research reinforces the importance of addressing both symptomatic and subclinical spinal dysfunction to optimise nervous system function. For patients, it highlights that chiropractic care provides benefits beyond pain relief, including improved body awareness, coordination, and movement efficiency.
What This Means
Even if you do not experience pain, spinal adjustments can help your brain and body communicate more effectively, supporting smoother movement, better balance, and enhanced coordination. Chiropractic care is therefore valuable for maintaining optimal nervous system performance and overall health.
