Understanding the neuroscience of proprioception, predictive motor control, body awareness, and neuroplasticity—and why comprehensive chiropractic care should consider more than pain and joint mobility.
Every movement we perform requires an extraordinary amount of coordination.
When we reach for a glass, turn our head, walk across an uneven surface, or maintain our balance, the nervous system must continuously process information about the body and its environment.
Our brain needs to know where our limbs are positioned, how quickly we are moving, how our weight is distributed, and what adjustments are necessary to accomplish the intended movement.
Much of this occurs automatically, without requiring conscious attention.
The brain receives sensory information from muscles, joints, skin, eyes, and vestibular organs while simultaneously sending motor commands to produce movement.
It must integrate these signals, predict the consequences of movement, detect errors, and adapt future responses.
This remarkable process is known as sensorimotor integration.
For clinicians working in chiropractic care, physiotherapy, and movement rehabilitation, understanding sensorimotor integration offers a more complete perspective on how the musculoskeletal and nervous systems work together.
It also raises important questions about how pain, injury, changes in movement, and rehabilitation may influence the body's sensory and motor functions.
Recent research published in Nature Reviews Neuroscience has significantly advanced our understanding of these relationships.
In 2019, neuroscientist Kathleen Cullen reviewed how the vestibular system integrates sensory and motor information during natural movement.
In 2022, Silvia Arber and Rui Costa examined the neural circuits connecting the brainstem and basal ganglia to coordinate movement.
More recent publications have investigated how the cerebellum predicts movement, how the brain constructs spatial representations of the body, and how sensory feedback contributes to locomotion.
Together, these discoveries reinforce a fundamental principle:
Movement is not simply the mechanical action of muscles and joints. It emerges through continuous interactions among the nervous system, the body, and the surrounding environment.
Understanding these interactions helps explain why comprehensive rehabilitation may require more than reducing pain or restoring joint range of motion.
1. Movement Begins With Information: The Importance of Sensory Feedback
The nervous system cannot effectively control movement without information about the body's current state.
This information is supplied through multiple sensory systems.
Visual information identifies objects, environmental boundaries, movement, and spatial relationships.
The vestibular system detects head motion and orientation relative to gravity.
Somatosensory receptors provide information about touch, pressure, body position, and movement.
Within the somatosensory system, proprioceptors located in muscles, tendons, and other tissues contribute essential feedback about the position and mechanical state of the body.
These signals allow us to coordinate movement even when we cannot see our limbs.
For example, closing your eyes does not prevent you from knowing approximately where your arm is positioned.
This ability depends substantially on proprioceptive information.
However, sensory feedback does not operate in isolation.
The brain compares and combines incoming information from multiple sources.
The relative importance of different signals can change according to the task and environmental conditions.
For instance, maintaining balance on an unstable surface may require greater reliance on visual or vestibular information when somatosensory information from the feet becomes less reliable.
This flexibility is an essential feature of human movement control.
2. Proprioception: The Body's Internal Position-Sensing System
Proprioception is frequently described as the body's ability to sense its position in space.
Although this is accurate, proprioception involves several related processes.
It contributes to the perception of joint position, movement, muscular effort, and force.
Muscle spindles provide information related to muscle length and changes in length.
Golgi tendon organs contribute information about muscular tension.
Additional receptors in the skin and joint-associated tissues provide complementary sensory signals.
Together, these inputs help the nervous system estimate the position and movement of different body segments.
Proprioception is essential for activities ranging from simple postural adjustments to complex athletic movements.
It also contributes to the development and refinement of motor skills.
When we learn a new movement, sensory feedback helps identify differences between the intended action and what actually occurred.
Repeated practice allows the nervous system to modify motor commands and improve performance.
However, proprioceptive performance is not determined solely by the condition of peripheral receptors.
It also depends on attention, central sensory processing, motor experience, task demands, and the integration of information from other sensory systems.
Consequently, altered proprioceptive performance does not automatically indicate damage to an individual joint or receptor.
3. The Brain Does Not Simply React to Movement—It Predicts It
One of the most important developments in movement neuroscience is the recognition that motor control involves prediction.
If the nervous system relied exclusively on sensory feedback arriving after movement occurred, many actions would be too slow or inaccurate.
Neural transmission and sensory processing require time.
During rapid movements, delayed information may no longer accurately describe the body's current state.
To overcome these limitations, the nervous system uses previously learned relationships between motor commands and their expected sensory consequences.
These processes allow it to anticipate certain aspects of movement before sensory feedback becomes available.
This is often described through the concept of an internal model.
An internal model is a theoretical framework describing how neural systems may estimate movement dynamics, predict sensory consequences, or generate appropriate motor commands.
The Cerebellum and Predictive Motor Control
A 2025 review in Nature Reviews Neuroscience, Cerebellar Circuit Computations for Predictive Motor Control, explores how cerebellar circuits contribute to the accuracy, timing, and adaptation of movement.
The authors examine evidence for multiple computational theories, including internal models and learned feedforward control policies.
Their research emphasizes that the exact computations performed by the cerebellum remain an active area of investigation.
Nevertheless, its contribution to coordinated movement and motor learning is well established.
This is particularly relevant during activities that require rapid adjustments, such as catching an object, maintaining balance, or navigating an unexpected obstacle.
The nervous system does not wait until every movement error has occurred.
It uses experience and incoming information to anticipate the demands of movement and adjust accordingly.
4. The Brainstem, Basal Ganglia, and Cerebellum: A Network for Coordinated Movement
Movement is not controlled by a single region of the brain.
Instead, multiple neural networks contribute to selecting, initiating, coordinating, and refining motor activity.
A 2022 Nature Reviews Neuroscience article, Networking Brainstem and Basal Ganglia Circuits for Movement, describes how specialized neuronal populations participate in different aspects of motor control.
Brainstem Networks
The brainstem contributes to essential motor functions, including postural regulation, head and eye coordination, and aspects of locomotion.
It serves as an important interface between higher brain regions and spinal motor circuits.
The Basal Ganglia
The basal ganglia contribute to movement selection, initiation, reinforcement learning, and the coordination of goal-directed behavior.
They help regulate which motor actions are facilitated or inhibited under particular circumstances.
The Cerebellum
The cerebellum contributes to movement timing, coordination, error-related learning, and predictive motor control.
Its extensive connections with other brain regions allow it to influence multiple aspects of movement.
The Cerebral Cortex
Cortical networks participate in voluntary movement planning, sensory processing, and the performance of complex tasks.
These systems continuously interact.
A movement such as walking involves rhythmic spinal activity, brainstem postural regulation, sensory feedback, and higher-level planning when the environment becomes challenging.
The result is a distributed motor-control system capable of adapting to different circumstances.
5. The Spine and Spinal Cord: More Than a Mechanical Support System
The spine provides structural support while protecting the spinal cord and associated neurological structures.
The spinal cord serves as a major pathway for communication between the brain and body.
However, its role extends beyond transmitting information.
Spinal neural circuits participate directly in reflexes, coordinated muscle activity, and the regulation of movement.
A 2026 review published in Nature Reviews Neuroscience, Redefining the Central Pattern Generator for Vertebrate Locomotion, examines how spinal locomotor circuits contribute to rhythmic movement.
Central pattern generators are networks capable of producing coordinated rhythmic motor activity.
The review describes emerging evidence that these networks are dynamic, modular systems continuously influenced by sensory feedback and descending neural commands.
Much of the detailed circuit evidence comes from zebrafish and other experimental animal models.
Therefore, the findings should not be interpreted as direct evidence for a particular chiropractic treatment in humans.
Nevertheless, they demonstrate an important neurophysiological principle:
The spinal cord actively participates in movement coordination rather than functioning solely as a passive communication pathway.
This provides a foundation for understanding why sensory feedback from the body is important for motor regulation.
6. The Vestibular System: Understanding Movement Relative to the World
The vestibular system provides information about head movement and orientation relative to gravity.
It contributes to gaze stabilization, balance, posture, and perception of self-motion.
However, vestibular processing is not independent of the rest of the nervous system.
In her 2019 review, Vestibular Processing During Natural Self-Motion: Implications for Perception and Action, Kathleen Cullen describes how vestibular signals interact with proprioceptive, visual, and motor-related information.
A particularly important distinction involves the difference between voluntary and externally imposed movement.
When we voluntarily turn our head, the nervous system has information about the intended movement.
It can compare expected sensory consequences with incoming vestibular signals.
During an unexpected movement, sensory information may require a different neural response.
These processes help the nervous system distinguish self-generated movement from externally imposed motion.
More recent research by Mao and Gu, published in Nature Reviews Neuroscience in 2025, further explores how vestibular, visual, proprioceptive, and motor-command signals contribute to self-motion perception and navigation.
Their review emphasizes that accurate movement depends on combining several sources of information rather than relying on one sensory system.
These relationships are relevant to patients experiencing balance difficulties, dizziness, or impaired movement coordination.
However, vestibular dysfunction requires appropriate diagnostic assessment and should not automatically be attributed to spinal dysfunction.
7. The Body Schema: How the Brain Represents the Body in Space
Another important concept in neuroscience is the body schema.
The body schema is a dynamic sensorimotor representation that helps the nervous system estimate the position and dimensions of the body.
It supports movement planning and interaction with the surrounding environment.
Unlike a conscious mental image of the body, the body schema often operates automatically.
For example, when reaching for an object, the nervous system must estimate the position and length of the arm while coordinating movement toward the target.
It must also account for changes in posture and the position of other body segments.
A 2024 study published in Scientific Reports, Multisensory Conflict Affects Body Schema and Reaching Space, examined how conflicting visual and tactile signals influence body representation.
Researchers used experimental conditions in which visual information about touch was synchronized or delayed relative to actual tactile stimulation.
The conflicting sensory condition altered measures of body representation and judgments about reachable space.
These findings demonstrate that certain aspects of body representation are dynamic and responsive to sensory information.
Importantly, the study did not investigate chiropractic care.
Its relevance lies in establishing that the nervous system's representation of the body can change according to the consistency of incoming sensory signals.
This provides a scientific foundation for studying sensorimotor adaptation without establishing that any particular manual therapy reliably modifies the body schema.
8. Pain Can Influence Movement and Sensory Processing
Pain is not simply an indication of tissue damage.
It is a complex protective experience shaped by nociceptive signaling, central nervous system processing, previous experiences, and contextual factors.
Persistent pain can influence how individuals move.
People experiencing pain may reduce movement amplitude, alter muscle activation, adopt protective postures, or avoid certain activities.
Some adaptations are appropriate and protective during acute injury.
However, when protective movement patterns persist beyond their usefulness, they may contribute to reduced movement variability, physical deconditioning, or functional limitations.
A 2025 systematic review published in Frontiers in Pain Research, Sensory Processing in Medically Unexplained Pain Syndrome, examined relationships between chronic pain conditions and sensory processing.
The authors reviewed studies involving conditions such as fibromyalgia, complex regional pain syndrome, and neuropathic pain.
Their findings identified altered sensory thresholds across several sensory modalities in some chronic pain populations.
These observations are relevant to the broader understanding of pain and sensory function.
However, sensory findings in chronic pain are heterogeneous and are not yet reliable diagnostic biomarkers for most of these conditions.
They also do not establish that spinal manipulation reverses central sensitization or corrects abnormal sensory processing.
The research instead reinforces the importance of examining pain within a broader neurological and functional context.
9. Neuroplasticity: How the Nervous System Learns and Adapts
Neuroplasticity refers to the nervous system's capacity to change its structure or function in response to experience, learning, injury, and other influences.
It is essential for motor learning and rehabilitation.
When individuals practice a movement repeatedly, neural networks can adapt.
The nature of these adaptations depends on the task, intensity, frequency, feedback, and broader physiological context.
For example, learning to balance on an unstable surface involves repeated exposure to altered sensory and mechanical demands.
The nervous system must refine how it integrates sensory information and generates appropriate motor responses.
Likewise, rehabilitation following musculoskeletal injury often requires more than restoring tissue healing or reducing pain.
Patients may need to rebuild strength, coordination, movement confidence, and tolerance to physical demands.
However, neuroplasticity should not be treated as an automatically beneficial process.
Nervous system changes can support effective adaptation, but maladaptive learning and persistent protective behaviors can also develop.
Effective rehabilitation seeks to encourage functional adaptation through appropriate practice and feedback.
10. What Does This Mean for Chiropractic Care?
Chiropractic care has traditionally emphasized the assessment and conservative management of musculoskeletal disorders, particularly those affecting the spine.
Manual therapies may influence pain, movement tolerance, and musculoskeletal function in selected patients.
Researchers have also investigated whether spinal manipulation produces measurable neurophysiological changes.
Proposed mechanisms include alterations in mechanoreceptor activity, sensory input, spinal reflexes, pain processing, and motor control.
However, the evidence supporting these mechanisms varies considerably.
A 2026 exploratory randomized controlled trial published in Chiropractic & Manual Therapies investigated the immediate effects of upper cervical manipulation on cervical sensorimotor control.
Thirty-five individuals with chronic primary neck pain were assigned to manipulation or sham treatment.
The researchers observed differences in certain measures of movement speed and movement time.
However, the primary measure of movement accuracy did not demonstrate a statistically significant between-group improvement.
The study was small and evaluated immediate outcomes.
Its findings therefore do not establish that cervical manipulation produces lasting improvements in sensorimotor function.
A separate 2024 randomized trial involving patients with chronic low back pain found that a single spinal manipulation session reduced local pain sensitivity but did not improve postural stability.
These findings illustrate why it is important to distinguish plausible mechanisms from demonstrated treatment effects.
The established role of sensory feedback in movement does not automatically demonstrate that manipulating a joint improves neurological performance.
Clinical interventions should be evaluated according to their actual outcomes, effectiveness, safety, and relevance to the individual patient.
11. Why Manual Therapy and Exercise May Serve Different Roles
One important implication of contemporary rehabilitation research is that passive treatment and active rehabilitation should not be considered interchangeable.
Manual therapy may help selected patients reduce pain or improve movement tolerance.
These changes can sometimes make it easier to participate in exercise and functional activity.
However, improvements in strength, endurance, motor coordination, and physical capacity generally require appropriately prescribed activity and practice.
For example, a patient with chronic neck pain may experience symptom relief following manual treatment.
Yet they may continue to demonstrate limited cervical endurance, reduced movement confidence, or difficulty maintaining head position during certain tasks.
Addressing these limitations may require cervical strengthening, motor control exercises, graded activity, and other rehabilitation strategies.
Similarly, someone with recurrent low back pain may benefit from improving physical conditioning and developing confidence in performing relevant movements.
The appropriate combination of interventions depends on the patient's diagnosis, functional limitations, preferences, and goals.
The purpose of integrating manual therapy with exercise is not to assume that adjustments are necessary before effective movement can occur.
It is to select treatments according to the clinical problems they are intended to address.
12. Movement Screening: Looking Beyond the Site of Pain
The complexity of sensorimotor control also supports considering movement function during musculoskeletal assessment.
Pain location does not always reveal every relevant functional limitation.
For example, a person experiencing recurrent shoulder discomfort may also have limitations in thoracic mobility, shoulder strength, or movement tolerance.
A runner with persistent knee pain may demonstrate relevant impairments involving hip strength, load management, or lower-limb capacity.
These findings do not mean that every movement asymmetry causes injury.
Nor does an abnormal screening result establish a specific diagnosis.
However, appropriate assessment can help identify factors worth addressing.
Functional movement screening, strength testing, balance assessment, and other evaluations may provide complementary information.
Their usefulness depends on the patient's presentation and whether the results guide treatment decisions.
When relevant, examination may include joint mobility, strength, endurance, coordination, proprioceptive performance, and functional tasks.
The goal is to understand the individual's current capabilities and identify opportunities for meaningful improvement.
13. From Movement Correction to Movement Capacity
Traditional rehabilitation language often emphasizes correcting dysfunctional movement.
However, not every variation from an idealized movement pattern is pathological.
Human movement is highly variable.
Individuals can accomplish similar tasks using different strategies depending on body structure, experience, physical capacity, and environmental demands.
Movement variability can be beneficial because it allows adaptation.
For example, walking across uneven terrain requires continual adjustment rather than rigid repetition of one movement pattern.
This is why rehabilitation should not focus exclusively on making every person move according to one predetermined standard.
A more useful goal is developing sufficient movement options and physical capacity to perform meaningful activities safely and effectively.
For some individuals, that involves restoring mobility.
For others, it involves increasing strength, improving balance, reducing movement-related fear, or gradually reintroducing activities previously avoided.
The objective is not necessarily perfect movement.
It is adaptable, efficient, and functional movement suited to the demands of the individual and their environment.
14. Special Considerations: Hypermobility and Complex Neurological Conditions
Not all patients respond to mechanical loading in the same way.
Individuals with generalized joint hypermobility, connective tissue disorders, or certain neurological conditions may require modified assessment and rehabilitation strategies.
A 2024 review in Frontiers in Neurology, Neuraxial Biomechanics, Fluid Dynamics, and Myodural Regulation, explored relationships among connective tissue mechanics, neural structures, and conditions associated with hypermobility.
The authors discuss how differences in tissue properties may influence mechanical loading and potentially complicate clinical presentations.
However, many proposed mechanisms remain hypotheses requiring further investigation.
The review does not establish that spinal manipulation can treat cerebrospinal fluid disorders, Chiari malformation, craniocervical instability, or other complex neurological conditions.
In patients with suspected instability or serious neurological pathology, clinical safety and appropriate referral must take priority.
Likewise, new neurological deficits, progressive weakness, unexplained gait deterioration, or other concerning findings require medical assessment rather than routine manipulation.
15. The Future of Chiropractic and Rehabilitation: Toward a Systems-Based Approach
A September 2026 doctoral dissertation by Mark Evans Lindsay, A Neuroanatomical Framework for Physical Medicine and Rehabilitation, proposes a systems-based approach to understanding interactions among mechanical loading, neural function, and rehabilitation.
The dissertation examines tissue architecture, mechanotransduction, sensorimotor integration, and motor control.
Its central argument is that mechanical stimuli and rehabilitative exercise may influence nervous system function through several interacting pathways.
Importantly, the author explicitly identifies these proposed pathways as mechanistic hypotheses rather than established causal effects.
The work includes anatomical investigations, imaging studies, and multidisciplinary clinical case reports.
However, the case reports cannot isolate the effects of manipulation from other components of treatment.
This is a valuable distinction.
The dissertation provides a framework for generating research questions and integrating knowledge across disciplines.
It does not establish that a particular manipulation technique can predictably produce specific changes in brain activity or neurological function.
Nevertheless, the broader direction is consistent with contemporary rehabilitation science.
Movement and musculoskeletal function are best understood through interactions among peripheral biomechanics, sensory feedback, central motor control, behavior, and environmental demands.
16. Our Approach to Chiropractic and Movement Rehabilitation
We recognize that musculoskeletal health involves more than joint mobility and pain intensity.
Our chiropractic approach considers the relationships among musculoskeletal structures, nervous system function, movement behavior, and individual physical demands.
Depending on the patient's presentation, assessment may involve joint mobility, muscular strength, movement quality, balance, coordination, and relevant sensorimotor functions.
For patients experiencing persistent or recurrent symptoms, we also consider whether limited physical capacity, movement-related fear, or other modifiable factors may be contributing to functional difficulties.
Treatment is individualized according to the examination findings, clinical indications, patient preferences, and safety considerations.
When appropriate, chiropractic care may be integrated with therapeutic exercise, physiotherapy, functional movement screening, strength and conditioning, or other rehabilitation approaches.
This allows treatment to address different dimensions of physical function rather than relying exclusively on passive interventions.
Our goal is not to claim that chiropractic adjustments directly correct neurological disorders or produce universal improvements in brain function.
Instead, we seek to use appropriate musculoskeletal interventions while helping patients develop the movement capabilities, confidence, and physical independence necessary for long-term health.
We also recognize the importance of interdisciplinary collaboration.
Patients with neurological, vestibular, cardiovascular, or other medical concerns may require additional assessment and coordinated care with qualified healthcare professionals.
Conclusion: The Future of Musculoskeletal Care Is Both Mechanical and Neurological
Human movement is an extraordinary example of biological coordination.
The nervous system continuously integrates information from muscles, joints, skin, eyes, and vestibular organs while generating the motor commands necessary for posture and movement.
The brain predicts the consequences of movement, interprets sensory feedback, and adapts through experience.
These processes involve distributed networks throughout the cerebral cortex, cerebellum, basal ganglia, brainstem, and spinal cord.
Contemporary neuroscience provides increasingly detailed explanations of how these systems operate.
For chiropractic and rehabilitation professionals, the implications are important.
The spine is both a mechanical structure and a source of sensory information.
Pain and injury can influence movement behavior.
Rehabilitation can support motor learning and functional adaptation.
And effective treatment should account for the individual's clinical presentation rather than assuming that one intervention addresses every component of dysfunction.
However, scientific accuracy requires distinguishing the established mechanisms of human movement from the still-developing evidence concerning particular treatments.
The future of chiropractic care should not depend on claiming that spinal adjustments control the brain. It should involve understanding how musculoskeletal function, sensory feedback, and motor control interact—and using that knowledge to guide safe, individualized, evidence-informed rehabilitation.
We believe this approach connects chiropractic care with contemporary neuroscience, functional movement, and the broader goal of helping individuals build durable physical capacity and independence.
