The spine is divided into 5 regions: cervical, thoracic, lumbar, sacral and coccygeal. Regarding the mobility, cervical column (C1-C7) is the most mobile, column thoracic (T1-T12) is less mobile and the lumbar (L1-L5) shows a large movement of flexion-extension. During the lifetime, the spine is subject to various internal and external actions. Prolonged movements of muscles, ligaments, tendons, bones or joints, trauma, osteoporosis, degenerative diseases joints, spinal infections, bone compression, can cause various changes in spine and intense pain (especially at the cervical and lumbar zone). The treatment consists in reducing this pain by applying ice, medicines (analgesics, anti-inflammatory, and muscle relaxants), improving mobility and flexibility with exercises or physiotherapy and also avoids producing a new injury by changing the usual activities and unfavorable body’s positions during sleep or sitting.

Thanks to the evolution of the surgery, methods of treatment in different diseases, manufacturing technology and apparition of various materials, using orthosis has a great importance in the pathology of orthopedic, neurologic, rheumatologic, plastic and reparative surgery, neurosurgery, traumatology and sports medicine.
Orthosis application is currently one of the main methods of the medical recovery. Othosis are external devices that applied across a segment of the body prevent or correct the malfunction of that segment.
Spinal orthosis’ aim is to support and correct posture and spinal alignment, prevent and correct the deformation due to vicious positions (kyphosis, scoliosis, lordosis), managing to reduce pain by local heat, massage effect, reducing the axial load, limiting mobility, stabilizes spinal segment, allowing immobilization of the spine after trauma or surgery (6-12 weeks), maintain kinesthetic memory (for movement prohibited)
