Which statement accurately describes the LSO Knight brace?

• A. Flexion, extension and lateral control
• B. Attaches to skull by screws
• C. Allows early mobilization
• D. Provides max support by spreading forces over larger area

Answer: (A)

The LSO Knight brace is a rigid thoracolumbar orthosis that stabilizes the lumbar spine by limiting movement in multiple planes. It achieves this by applying targeted pressure to create a three-point control effect, which restricts flexion, extension, and lateral bending of the trunk. That’s why the statement describing control of flexion, extension, and lateral movement best captures what the Knight brace does. The other options don’t fit: this brace does not attach to the skull with screws (that setup is for halo devices), it isn’t primarily defined by attaching to the skull, and while some immobilization occurs, its key purpose isn’t simply “early mobilization.” It also doesn’t rely on spreading forces over a larger area to provide maximal support; instead, it stabilizes the spine through targeted three-point control to limit motion.
