What is the inferior trim line for a TLSO?

The inferior trim line for a TLSO (Thoraco-Lumbo-Sacral Orthosis) is typically positioned 1/2" to 1" above the seating surface. This positioning is critical for several reasons.

Firstly, having the inferior trim line above the seating surface allows for optimal support while accommodating the natural movements of the body when seated. It prevents discomfort and pressure on areas of the body that may be under significant strain due to posture or seating position.

Moreover, sitting can affect the biomechanics of the spine and pelvis, so the trim line's placement is designed to enhance stability without restricting necessary mobility. This ensures that the TLSO remains functional and comfortable for activities of daily living, while effectively providing the necessary support to the thoracic, lumbar, and sacral regions.

The other choices do not align with the standard clinical guidelines for TLSO design, which emphasizes the importance of an accessible and comfortable inferior trim line that facilitates patient care and functional mobility.
