High lumbar L1-L2 functional mobility is typically characterized by which level of ambulation?

• A. Limited household ambulation
• B. Unrestricted community ambulation
• C. Full-time wheelchair mobility
• D. No functional mobility

Answer: (A)

At L1–L2, hip flexion is usually preserved, allowing some stepping motion, but knee and ankle control and trunk stability are often insufficient for independent walking beyond short distances. This means ambulation is possible, but limited in scope and endurance, making home use the most realistic setting with assistive devices or bracing. The energy cost and balance demands are too high for reliable outside-the-home walking, so most individuals at this level fit the description of limited household ambulation.
