Throughout life, our spine is under extreme strain...
The column is made up of vertebrae, muscles and discs that separate the vertebrae and act as a shock absorber. Excessive strain, such as frequent and repetitive movements, carrying loads, over-intensive sport or even sitting for long periods of time, ... can cause wear and tear and degeneration of our spine, and lead to most lumbago (back pain).
From a physiological point of view, the core of the intervertebral discs is composed of 90% water, hence its damping properties. As the only non-vascularized tissue, the nucleus deflates when compressed. It only deflates by reducing pressure (osmosis) when we are lying down.
As in adults, back pain is increasingly common in children and adolescents. Experts estimate that, depending on age, 20 to 50% of children between the ages of 10 and 15 have back pain.
During his or her school day, a student spends about
6.5 hours per school day in a seated position.
Unfortunately, school furniture is not suitable for every child. The size of children and teenagers varies greatly at each age, making it difficult to provide correct and suitable furniture for every child in schools. In addition, the horizontal work surface forces the child to lower his or her head and bend down to work.
Long-term sitting at school
damages our children's backs... from the age of 6.
The consequences are mechanical and neurological.
Abnormal demands on the spine of children and adolescents during the sensitive period of their growth influence the future of their back and promote low back pain in adulthood.
The muscles of the child's trunk are not yet sufficiently developed and strong enough to withstand sitting for hours without great effort.
Her attention in class decreases because she is then directed more towards the intense muscular effort imposed on her, causing distraction.
A well-fitting seat will help by reducing the muscular and mental effort required to remain seated for long periods of time. The child will be less agitated in the chair.
When moving, children often only want to compensate for muscle tension.
In the child in the classroom, there are two types of behaviour in response to the constraints of sitting for long periods of time: the "wise" child who does not move but ends up squeezing into his or her seat; the "fidgeting" child who does not stop moving, is distracted and distracted.
Between the ages of 6 and 12, the child is in full motor development. He still needs to refine his body schema.
His brain uses tactile, proprioceptive, vestibular and visual integration mechanisms that result in either a muscular response or relaxation.
Why give a cushion to your children?
The NOA cushion helps to maintain the three natural curves of the column in the sitting position (see photo on the right) and to energize the seat.
Spontaneously, when sitting, the pelvis tends to tilt backwards (see photo on the left). The cushion makes it easier to reposition the pelvis forwards (see photo on the right).
This correct and natural posture is essential for maintaining attention, alertness and listening skills and for promoting perseverance in the task.
Indeed, repositioning the head above the shoulders promotes good vascularization of the brain, beneficial for good concentration and better learning.
In addition, sitting on a dynamic seat cushion will cause imperceptible movements of the pelvic and back muscles, which will allow the child to grow by strengthening the erector muscles of the spine and prevent back pain caused by prolonged sitting.
