How to score it

Starting from standing, assess the patient's ability to walk 10 feet on an uneven or sloping surface — indoor or outdoor, such as turf, gravel, or a ramp. Use clinical judgment to determine whether an available surface meets the intent of the item. See Guidance Manual Ch. 3 GG item-by-item tips for full scoring rubric.

The common error

Confusing this item with GG0170I (Walk 10 feet on a flat surface) and scoring the same performance for both — GG0170L specifically requires an uneven or sloping surface, and clinicians should seek one out (gravel, turf, a ramp) rather than reusing the flat-surface result.
