How does desensitization training progress through stimuli?

• A. Sudden, full exposure to all textures.
• B. Gradual exposure to textures, weights, and vibration to reduce hypersensitivity.
• C. No exposure; recommend complete rest.
• D. Exposure to heat only.

Answer: (B)

Desensitization training uses graded exposure to tactile input to retrain the nervous system’s response to touch. The idea is to start with textures that are only mildly irritating and progressively move to more challenging textures, while also adding proprioceptive (weights) and vibratory stimuli as tolerance grows. By carefully increasing the variety and intensity of stimuli in small, manageable steps, the nervous system learns to dampen hypersensitive reactions and tolerate everyday textures and activities. This gradual approach prevents overwhelming the patient and promotes lasting desensitization.

Jumping straight to full exposure would likely trigger strong protective reactions and reinforce avoidance. Complete rest won’t change hypersensitivity, and exposing only to heat targets a different sensory aspect and doesn’t address tactile desensitization comprehensively.
