The Therapeutic Roller Rider, model AP 5003, is a scooter board with trunk support designed for use by children with poor trunk control and weak lower extremities. By moving the handlebars from side to side, the child can play independently. Upturned handlebars encourage trunk extension and rotation, while promoting shoulder stability and upper extremity reciprocal movement. The board has a footplate to position the feet and an adjustable lower extremity strap. The board also has a padded back support to aid trunk stability, an adjustable seat belt, and a padded seat for proper pelvis positioning. This scooter board can be used indoors and outdoors on any hard, smooth surface.
