Which statement about SCALE is true?

Which statement about SCALE is true?

• A. It requires neuroimaging to interpret results.
• B. It is valid only for children who walk independently.
• C. It measures selective voluntary motor control of the upper extremities.
• D. It assesses selective voluntary motor control of the lower extremities and is applicable across GMFCS levels in children with spastic CP.

Answer: (D)

The main idea here is understanding what SCALE measures and who it can be used with. SCALE looks at selective voluntary motor control—the ability to move a limb segment independently, without unwanted movement in other joints or along abnormal synergy patterns. For CP, this is a key ability that affects gait and daily function. SCALE is a clinical tool that assesses lower-extremity selective voluntary motor control by having a child perform isolated hip, knee, and ankle movements and scoring how well they dissociate those movements. It does not require any neuroimaging, which makes it a practical, bedside measure. Importantly, SCALE is designed to be applicable across GMFCS levels, so it can be used with children who walk independently as well as those who rely on assistive devices or do not ambulate at all. This broad applicability, focused on the lower limbs, is what makes the statement true. The other options don’t fit because imaging isn’t part of SCALE, it isn’t limited to upper-extremity movements, and it isn’t restricted to children who walk independently.
