Which condition indicates a backward tilt-in-space frame?

• A. Unable to sit upright or perform weight shifts
• B. Issues with sliding or extensor tone
• C. Cannot support the head
• D. Good trunk control

Answer: (A)

A backward tilt-in-space frame is used when the person cannot maintain an upright seated posture and cannot perform effective weight shifts. The tilt back supports the trunk and head by repositioning the body into a more stable, posturally supported position, reducing the need for continuous active trunk control and helping with pressure relief. This makes it appropriate for someone with weak or variable trunk control who otherwise would slump or slouch and risk loss of balance. If someone can sit upright with good trunk control and can shift weight safely, a tilt-in-space frame is less necessary, and a frame that maintains a more upright position would be more appropriate.
