New Orthosis: The Thoracic Lumbar Sacral–Hip Spica Orthotic Sitting Frame

ABSTRACT Introduction This article describes the benefit of combining a thoracic lumbar sacral orthosis (TLSO) and a hip spica orthosis (HSO) to create a sitting frame for children with emerging neck and trunk control who cannot sit by themselves. Materials and Methods A child with motor disabilities who cannot sit independently benefits from a custom floor sitting frame. The sitting frame's thoracic lumbar sacral orthosis and hip spica orthosis are separate entities but are used together to allow a child to sit on the floor independently. Although the presented child does not need added head support, the TLSO-HSO sitting frame can be fabricated with cervical support. This sitting frame has a versatile joint allowing for movement between upright sitting and sitting with upper-limb weight bearing. The frame's hip joint can also be locked in different degrees of tilt. The described child uses the frame in a locked 90° upright position. Evaluation, fitting, fabrication, and reimbursement submission is explained. Conclusions Floor sitting is an important developmental milestone. Available equipment, such as floor sitters and compression garments intended to support a child in sitting, fail to sufficiently support all children with significant motor disabilities who have floor sitting goals. The TLSO-HSO sitting frame is a custom-made floor sitter that may give children with significant motor disabilities who have emerging neck and trunk control the support they need to independently sit on the floor. This orthosis has the potential to improve the lives of many children and their families as it can be used in both home and classroom settings and can give children with significant motor disabilities the opportunity to use their hands freely to play and to interact with peers during floor play time. Clinical Relevance Some children with severe motor disabilities cannot floor sit independently. The present study describes a new floor sitting frame that closes the gap between available products designed as these products do not meet the needs of all children with severe motor disabilities who have emerging neck and trunk control.
