What is one of the greatest indicators that gait should be discontinued?

• A. Hip flexion contractures
• B. Knee valgus
• C. Ankle creep
• D. Low back pain only without functional loss

Answer: (A)

Severe hip flexion contractures are the strongest sign that walking is no longer feasible. When the hip cannot straighten during stance, the leg can’t achieve a stable, upright alignment needed for efficient and safe weight bearing. This fixed position forces a crouched gait, makes it very energy‑intensive to ambulate, and raises risks such as skin breakdown and joint strain. Even with braces or therapy, if the hip remains flexed, the ability to lengthen the leg and progress forward is severely limited, so discontinuing gait and shifting to other mobility options becomes appropriate.

Knee valgus is more about lower‑limb alignment that can often be managed with therapy or orthotics. Ankle creep indicates a timing or control issue at the ankle, which may be correctable with devices or specific exercises. Low back pain that occurs without functional loss isn’t by itself a definitive reason to stop gait; it needs to be evaluated in context with overall function and pain impact, but it doesn’t carry the same decisive weight as a fixed hip deformity.
