Question

Quizplus · Accepted Answer

The lack of sensation in the foot of a diabetic patient with a nonhealing ulcer is most commonly due to peripheral neuropathy, a common long-term complication of diabetes. Brown-Séquard syndrome is a spinal cord injury resulting in weakness or paralysis on one side of the body, while Raynaud's disease is a condition that causes blood vessels in the fingers and toes to narrow, leading to decreased blood flow and pain. Claudication refers to pain or cramping in the legs during activity due to decreased blood flow, and would not manifest as a lack of sensation in the foot.
