The spine presents three physiological curves (cervical lordosis, dorsal kyphosis, lumbar lordosis). These spinal curves are crucial to answer effectively to everyday life’s requests: flexion, extension, inclination, rotation, jump, loading weights.

Hyperkyphosis refers to an excessive curvature of the dorsal kyphosis that can be classified into two categories: structural kyphosis, due to a congenital vertebral malformation or Scheuermann’s disease, and postural kyphosis, if the increased curve of the spine is related to bad posture.

In the case of postural kyphosis, the use of the brace K1 Posture Keeper® can be useful to restore the correct posture because it induces a dorsal dynamic call, through the reinforcement of the extensor muscles of the trunk and the activation of a neurological response.


The K1 POSTURE KEEPER® acts on the dorsal dynamic and is recommended for:
• posture correction and stabilisation
• painful postural syndrome
• curved back or hyperkyphosis
• juvenile kyphosis
• non-neurological scapulothoracic dyskinesis

Biomechanical mechanism

Using the B.A.C.K. (Back Active Correction Keeper)® patented system, K1 generates forces applied at particular points, mimicking the action of the muscles of the trunk extensors.
K1 restores correct posture by acting dynamically on the back, in accordance with the principle of balance between forces acting on the body.
K1 counteracts the action of the flexor muscles of the trunk .
(lower trapezius, Rhomboid, Serratus anterior)

Receptor Mechanism

K1 acts on the mechanoreceptors and proprioceptors, gradually adapting them to a new equilibrium corresponding to the correct posture.
K1 allows activation of a receptor response as a result of the modified balance between flexion and extension of the back.
