For functional long sitting in tetraplegia, the recommended SLR angle is approximately 110 degrees.

For functional long sitting in tetraplegia, the recommended SLR angle is approximately 110 degrees.

• A. 60 degrees
• B. 90 degrees
• C. 110 degrees
• D. 140 degrees

Answer: (C)

The key idea is that the straight-leg raise (SLR) angle used in this context reflects how much hip flexion is available to position the leg for a functional long-sitting posture in tetraplegia. Reaching about 110 degrees of hip flexion with the knee kept straight provides enough mobility to bring the leg forward into a long-sitting position while maintaining a stable pelvis and allowing the arms to work for daily tasks. This degree of flexibility helps keep trunk alignment comfortable and prevents compensatory movements that could destabilize posture. If the angle were much smaller, like 60 degrees, there wouldn’t be enough hip flexion to place the leg forward for functional tasks. A 90-degree angle is often not sufficient for truly functional long sitting, where the leg needs to be positioned forward with control. Going up to 140 degrees would require excessive hip flexion, which can be unsafe or uncomfortable and may disrupt pelvic stability or provoke spasticity.
