Which of the following is listed as a factor that affects ambulation?

• A. Motor level
• B. Eye color
• C. Blood type
• D. Hair texture

Answer: (A)

Ambulation in individuals with spinal involvement depends largely on the motor level of the spinal cord—the lowest segment with normal motor function. This level determines which muscles below the lesion can still be activated, shaping a person’s ability to stand, transfer, and walk, as well as what braces or devices might be needed. A higher motor level means more muscles are impaired, making walking more challenging and increasing reliance on assistive devices or seating, while a lower motor level allows greater leg function and potential ambulation. Traits like eye color, blood type, or hair texture don’t reflect nerve control or muscle strength, so they don’t predict walking ability.
