We officially divide the spine into 4 sections: the sacrum as the base, 5 lumbar vertebrae, 12 thoracic vertebrae and 7 cervical vertebrae, all of which are connected together with intervertebral discs as "buffers" to form an elastic axis with good mobility. Changes to this axis due to poor posture, flat back, scoliosis, etc. can therefore lead to muscle tension, fascial adhesions, trigger points or even nerve entrapment.
This very complex, dynamic complex "head-neck-shoulder", is held by ligaments, supported and moved by muscles, held together by fascia and protected from pressure loads by intervertebral discs.
Example: "Mobile phone neck"
- With an upright posture, the head puts a 5 kg load on the cervical spine
- At PC work in a slightly tilted head position already with 17 kg
- With strong diffraction, as with the use of a mobile phone even with 28 kg
