KISS stands for Head joints Kinetic Imbalances due to Suboccipital Strain. In older children it is also called KIDD.
Both KISS and KIDD are considered to be non-existent by regular medical practitioners and despite several investigations into the cause of these complaints have provided no clear answers.
KISS generally occurs at birth, although there are some who claim that it can arise in the womb because of an unnatural posture, for example; a long time in the same position or breech. A very quick delivery, a forceps delivery, use of the vacuum pump, or caesarean section gives an increased chance of KISS / KIDD. Because there is no clear reason for KISS / KIDD there is also little that medicine and specialists can do to prevent it.
Scientific studies show that the upper neck joints and their proper functioning are important for the motor development and postural development of a child. In the first months they are also important for good breathing and swallowing reflexes. When the upper cervical vertebrae do not function properly, a child is limited in the development Due to lack of knowledge / experience, children with KISS are quickly considered to be a colicy baby, while there is indeed a basis for the often uncontrollable crying. KISS is not always accompanied by excessive crying, it is only one of the characteristics that can be present.

Some treatments often have an amazing effect. There are therapists who claim that one treatment is sufficient, but this is often not the case. The muscles and the body need time to get to the new position. Follow-up treatments are almost always necessary. Older children generally require longer treatment than when intervening at an early stage. It is good to have the child checked every six months until the second year of life. In some literature it is also indicated that the child should be regularly checked by the treating therapist well into primary school, because the area of the spine in the neck is still very vulnerable.
