Low bone mineral density affects 77% of children with severe cerebral palsy (GMFCS IV \& V) with an increased fracture risk of 4%. One strategy supposed to improve bone mineral density is verticalisation with static devices. Nowadays there is no time recommendation of verticalisation however high intensity verticalisation has been shown to be effective in improving bone mineral density in childrens with cerebral palsy, but difficult to apply in real life due to lack of qualified therapists, device's complexity, and severe impairment in those children. The investigators aim to compare bone mineral density and bone remodelling factors of verticalized and non verticalized childrens with severe cerebral palsy as achieved in everyday life. The investigators conduced a retrospective study comparing bone mineral density and factors who influence bone remolling in severe cerebral palsy's according to whether they are verticalized or not.

Variation of Densitometric Z score between both groups
A Z-score compares the patient bone density to the average bone density of people your own age and gender.A Z-score is helpful in diagnosing secondary osteoporosis and is always used for children. It is most useful when the score is less than 2 standard deviations below this normal. In this setting, it is helpful to scrutinize for coexisting illnesses or treatments that may contribute to osteoporosis such as glucocorticoid therapy, hyperparathyroidism, or alcoholism.
