What is the postural system and why is it key to your health?
The postural system is the set of structures and mechanisms that enable the body to maintain its balance, adapt to its environment and move efficiently. It does not depend solely on muscles or bones, but on the integration of multiple systems working in coordination.
Posture is not something fixed or static. It is a dynamic process that constantly adjusts in response to the stimuli the body receives. That is why, when we talk about posture, we are not just talking about ‘standing up straight’, but about how the body organises its movement and adapts to each situation.

That is why, when we talk about posture, we are not just talking about ‘standing up straight’, but about how the body organises its movement and adapts to each situation.
Posture as a dynamic process
Every movement we make involves a reorganisation of our postural system. From walking to sitting, the body is constantly making adjustments to maintain balance.
When this system is working properly, movements are efficient and do not cause strain. When it malfunctions, compensatory mechanisms arise that can lead to pain or functional impairments.

Why posture isn’t just down to your muscles
Although muscles are important, posture is primarily regulated by the nervous system. It is the brain that interprets the information it receives from the body and decides how to coordinate posture and movement.
That is why focusing solely on strength training or stretching does not always solve postural problems.

Sensory integration: the foundation of the postural system
The postural system functions by integrating information from various sensory systems. This information is processed by the nervous system to generate an appropriate response.
What is sensory integration?
Sensory integration is the nervous system’s ability to receive, organise and interpret information from the body and the environment.
When it comes to posture, this information is key to knowing where we are, how we move and how we need to adjust to maintain our balance.
Systems involved in postural control
Postural control depends mainly on three systems:
Visual system
It provides information about the environment and the body’s position in relation to space.
Vestibular system
Located in the inner ear, it provides information about head movement and balance.
Proprioceptive system
It gathers information about muscles, joints and tissues, indicating the body’s position and movement.
The proper functioning of these systems and their integration is essential for efficient posture.
How is the skin related to the postural system?
The skin plays a key role in sensory integration, although this often goes unnoticed.
The skin as a sensory receptor
La piel contiene múltiples receptores que detectan presión, temperatura, vibración y contacto. Esta información es enviada al sistema nervioso y forma parte del control postural.
For example, the contact between the foot and the ground provides key information for maintaining balance.

The relationship between tissue, fascia and posture
Fascia connects different structures in the body and transmits tension. If the tissue loses mobility or elasticity, it can disrupt sensory input and affect posture.
That is why the condition of the tissue has a direct influence on how the body organises itself.

What happens when sensory integration fails?
When one or more systems do not function properly or do not integrate well, the body develops compensatory strategies.
The body’s adaptations and compensations
The nervous system always seeks the most efficient way to maintain balance, even if it is not the most correct one.
This may result in:
This may result in:
- Muscle strains
- Movement disorders
- Postural imbalances
Relationship with pain and dysfunction
Pain often arises not from a specific injury, but from poor postural control.
Compensatory movements that persist over time can cause discomfort or limit functionality.

How the postural system influences movement and performance
An efficient postural system allows you to move more easily, with less effort and a lower risk of injury.
Efficiency of movement
When sensory information is properly integrated, the body makes precise adjustments that optimise movement.
This results in greater efficiency and lower energy expenditure.
This results in greater efficiency and lower energy expenditure.
Injury prevention
Good posture reduces unnecessary strain on the body’s structures, thereby lowering the risk of injury.
How to work on the postural system through physiotherapy
Any approach to the postural system must take sensory integration into account, not just the structural aspects.
Overall assessment of the patient
It is essential to analyse how the various systems involved operate and how they interact with one another.
Intervention regarding the sensory system
Treatment may include:
- Proprioceptive stimulation
- Balance exercises
- Motor control exercises
- Tactile stimulation
The importance of tissue in postural control
Improving the mobility and quality of the tissue helps to optimise the information reaching the nervous system.
This is where dermatofunctional physiotherapy techniques can also play a significant role.

The relationship between the postural system and daily life
Posture affects all our daily activities.
Posture at work and daily habits
Holding certain postures and repetitive habits can affect the postural system if they are not properly compensated for.
The importance of movement
The body needs variety and movement to maintain a healthy postural system.
When you should pay attention to your posture
There is no need to wait until pain sets in before taking action.
Warning signs
- Feeling of stiffness
- Recurrent pain
- Lack of balance
- Fatigue caused by maintaining certain postures
- Restricted movement
Start understanding your body through sensory integration
Understanding the postural system as a process of sensory integration allows us to address problems from a more comprehensive perspective.
It is not just a matter of correcting posture, but of improving how the body perceives, interprets and responds to information.

Frequently asked questions about the postural system
Is the correct posture to always stand up straight?
No. Posture is dynamic and changes constantly depending on the activity.
Can posture be improved?
Yes. With the right kind of training, sensory integration and motor control can be optimised.
Is pain always linked to posture?
Not always, but it is often influenced by how the body processes information and movement.
Which type of treatment is most effective?
A holistic approach that takes into account sensory integration, the nervous system and tissue quality.
