For children, young people and adults with complex needs, a wide range of postural equipment is needed for positioning in lying, sitting, standing and mobility. In some cases, support of the neck and head is also required, to enable and sustain an upright position of the head. This support is most commonly needed in a sitting and/or standing position, where gravity impacts upon head control. 

It is recommended that health professionals perform an assessment of an individual in different positions in order to establish the equipment that is needed. Usually the first aim is to decide on the type of postural support or mobility equipment, for example - a wheelchair that keeps the trunk, pelvis and lower extremities well aligned and supported. Once a suitable brand and style of chair has been identified, then an assessment for an appropriate head support can done, based on the needs of the individual.
