Desensitization training starts after which event?

• A. Before wound closure
• B. During wound closure
• C. After wound closure
• D. Never

Answer: (C)

Desensitization training targets reducing hypersensitivity in healing tissue by progressively exposing it to varied sensory input. It begins after wound closure because the skin and underlying tissues need to be protected so healing can complete without disruption. Introducing tactile stimuli during an open wound or while sutures are still present risks reopening, infection, or increased pain. Once the wound is closed, gentle, graded exposure to different textures, pressures, and temperatures helps nerve endings adapt, reduces sensitivity, and improves tolerance to touch for dressing changes and daily activities. Starting desensitization before closure or during closure would be unsafe and unnecessary—the appropriate time is after closure.
