In clinical and rehabilitative practice, posture is often framed as a structural outcome—an expression of skeletal alignment and musculoskeletal architecture. While anatomical factors undeniably influence postural tendencies, a growing body of evidence and clinical insight suggest that posture is primarily a conscious, learned behaviour, shaped by neuromuscular control, environmental context, and cognitive awareness. This perspective has significant implications for assessment, intervention, and patient education. Our clinical thinking and protocol setting must reflect this in patient education and the time allocated to motor learning rather than manual therapy alone.
Anatomy: The Framework, Not the Determinant
Anatomical structure provides the foundational framework for movement and alignment. Variations in spinal curvature, pelvic orientation, joint morphology, and connective tissue elasticity all contribute to an individual’s postural baseline. However, these structures are dynamic and responsive to mechanical loading, neural input, and behavioural conditioning.
Research in motor control and neuroplasticity demonstrates that the central nervous system can adapt postural strategies in response to training, feedback, and environmental demands. Thus, while anatomy may influence postural potential, it does not rigidly define it.
Posture as a Behavioural Output
Posture is not a static position but a dynamic, habitual output of the neuromuscular system. It reflects the cumulative effect of:
- Motor learning and repetition
- Sensorimotor integration
- Cognitive and emotional states
- Environmental ergonomics
These factors are modifiable through conscious intervention. For example, habitual slouching at a workstation is not a consequence of spinal shape but of repetitive motor behaviour reinforced by environmental setup and lack of proprioceptive awareness. Chronic postures may alter anatomical structures over time, such as connective tissue thickening and stiffness. This needs to be addressed by a manual therapist to reduce the inhibition to adapt a more efficient posture, however, the emphasis must remain that conscious decision is still the primary factor that alters posture and maintains posture.
The Role of Conscious Control and Neuroplasticity
Interventions such as the Alexander Technique, the Feldenkrais Method, yoga, and postural re-education leverage the brain’s capacity for neuroplastic change. These approaches emphasise awareness, intention, and movement quality, demonstrating that posture can be consciously altered through sensory feedback and motor retraining.
Moreover, studies in cognitive neuroscience show that posture is influenced by affective and attentional states. For instance, individuals experiencing anxiety or depression often adopt flexed, withdrawn postures, while confident individuals exhibit upright, expansive alignment. These patterns are not anatomical—they are behavioural and psychological
Clinical Implications
Understanding posture as a conscious construct reframes the therapeutic approach:
- Assessment should include behavioural, cognitive, and environmental factors—not just structural alignment.
- Intervention should prioritise motor control, proprioceptive training, and patient education, rather than simply manual therapy and passive correction.
- Patient empowerment becomes central, as individuals learn to take ownership of their postural habits and make sustainable changes.
Conclusion
While anatomical structure provides the scaffolding for posture, it is conscious decision-making, motor learning, and environmental interaction that shape how posture is expressed and sustained. Recognising posture as a modifiable behaviour, rather than a fixed anatomical outcome, opens the door to more effective, individualised, and empowering clinical interventions.

The first principal component included posturographic parameters concerning the AP variation in COP displacement: average AP distance from the mean COP, AP RMS distance and maximum distance between two points of the AP time series. Moreover, in a study comparing a quiet standing ST and DT with a simultaneous tone-counting task [96], fallers had a significantly greater area of sway, AP and ML standard deviation of COP displacement compared to non-fallers, but without any significant interaction between task condition and group. This might be due to the fact that quiet standing is a relatively easy task.
