High-level lesions may cease ambulation after how many years?

High-level lesions may cease ambulation after how many years?

• A. 1-2 years
• B. 3-4 years
• C. 5-6 years
• D. 7-8 years

Answer: (B)

High-level spinal lesions disrupt trunk and leg motor control, so walking is already energy-intensive and relies on limited muscles. As a child grows, the demands of ambulation increase while muscle strength at that high level may not keep pace. Orthopedic changes commonly develop—scoliosis, hip and knee contractures, and foot deformities—that further destabilize gait and raise the effort required to walk. These combined factors often push ambulation to cease by early preschool years, around three to four years of age, even in children who could walk with support earlier. This pattern reflects how lesion level shapes mobility: higher lesions tend to lead to loss of walking ability within that early age range, even with therapy and orthotic interventions.
