What is the primary objective of spinal orthoses?

To control pain by limiting motion and unloading spinal structures (correct)

To strengthen the muscles surrounding the spine

To increase spinal mobility and flexibility

To provide cosmetic enhancement to the spinal region

Which of the following is NOT a key design requirement for spinal orthoses to achieve their primary goal?

Increase muscle strength around the spine (correct)

Limit gross vertebral sway (motion) of the spinal column

Limit intersegmental motion at the injured site

Provide proper spinal alignment

For a single-level thoracolumbar compression fracture with up to 50% loss of segmental stiffness, what type of orthotic is typically recommended?

Flexible back brace

Rigid TLSO

Jewett-style TLSO (correct)

Lumbosacral orthosis (LSO)
