What is the functional mobility classification for low lumbar L4-L5?

• A. Household ambulation
• B. Independent running
• C. Wheelchair for long distances
• D. Bedbound

Answer: (A)

At this level, there is enough leg function to walk, especially with the aid of braces or mobility devices, for short distances inside the home. An L4–L5 lesion typically preserves balance and many movements needed for indoor ambulation, but long-distance walking or outdoor, unassisted mobility is generally not feasible. That’s why the best fit is household ambulation: the person can get around the home with assistance or devices, but not rely on unassisted or extensive community walking.

The other possibilities imply a more limited or different pattern of mobility (being bedbound, needing a wheelchair for long distances, or being able to run independently), which does not align with the typical functional profile at L4–L5.
