A physical therapist is developing a stretching program for a patient with C6 ASIA A SCI. What is the MINIMUM straight leg raise (SLR) range of motion recommended for functional long sitting activities in patients with tetraplegia?

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

Answer: (C)

In tetraplegia, keeping the hamstrings sufficiently flexible is crucial for performing long-sitting activities with a stable trunk. The straight-leg raise angle serves as a measure of hamstring length needed to bring the leg forward in a seated position without forcing the spine to compensate. A minimum of about 110 degrees of hip flexion with the knee extended (that is, a straight-leg raise of 110 degrees) provides enough length to position the leg in front of the body while maintaining an upright trunk. This level allows essential functional tasks in long sitting—such as donning shoes, reaching for objects, or placing the feet on a footrest—without excessive pelvic or lumbar motion that could destabilize posture or create compensatory patterns. If the SLR is only 60 or 90 degrees, the hamstrings are too tight for comfortable long sitting, leading to compensations and limited function. A higher angle like 140 degrees isn’t typically necessary for these activities and isn’t required to achieve the objective. So, the 110-degree minimum reflects the amount of hip flexion needed to support functional long-sitting tasks in tetraplegia without overextending or stressing the system.
