A technique that gradually retrains the nervous system to tolerate touch, temperature, and texture without pain.
What It Is
Desensitization therapy is a key component of physical therapy for amplified pain conditions like AMPS and CRPS. It involves systematically and gradually exposing the affected area to various sensations — touch, texture, temperature — to reduce the nervous system's heightened pain response. The principle is simple: by repeatedly and progressively exposing the nervous system to stimuli in a controlled way, the brain learns that these sensations are safe, not threatening.
How It Works
Desensitization typically involves: • Tactile desensitization: Touching the affected area with different textures (soft cloth, towel, sandpaper — progressing from gentle to rough) • Temperature desensitization: Alternating warm and cold water, ice massage • Vibration: Using a vibrating massager on and around the painful area • Weight-bearing: Gradually putting weight on the affected limb • Functional activities: Using the affected body part in daily tasks The key is progression — starting with tolerable sensations and gradually increasing intensity.
Evidence Overview
Desensitization is a well-established component of functional restoration programs for amplified pain. While it is typically studied as part of a broader PT program rather than in isolation, clinical evidence strongly supports its role in: • Reducing allodynia (pain from light touch) • Improving tolerance to normal sensations • Supporting overall functional recovery It is considered a standard of care in intensive pain rehabilitation programs.
Potential Benefits
Potential benefits include: • Reduced pain from everyday touch and contact • Ability to wear normal clothing comfortably • Improved tolerance for physical contact and activity • Key step toward functional recovery • Can be done at home as part of a daily program Desensitization is essential for patients with allodynia.
Limitations
Limitations include: • Can be uncomfortable or painful, especially initially • Requires consistent daily practice • Progress can feel slow • Must be part of a broader treatment program • Not sufficient as a standalone treatment Patient and family education about why it hurts and why it's important is crucial.
Risks & Side Effects
Desensitization is low-risk but can be challenging: • Temporary increase in pain during and after exercises (expected) • Emotional distress from confronting pain • Risk of overdoing it if not properly guided • Frustration or avoidance A skilled therapist provides structure, encouragement, and appropriate pacing.
Cost Overview
Desensitization is typically part of a physical therapy program: • Incorporated into regular PT sessions • Home program requires minimal equipment (various textures, ice, etc.) • No additional cost beyond PT For intensive programs, desensitization is a daily component.
Insurance Coverage
Covered under physical therapy benefits when part of a treatment program. No separate billing typically applies. For home programs, no insurance authorization is needed for the materials themselves.
Questions to Ask Your Provider
Questions to discuss with your therapist: • How do we incorporate desensitization at home? • What materials do we need? • How do we know when to progress to the next level? • What if the pain gets worse — should we stop or push through? • How long does each session take? • How do we keep a child motivated to do this daily? • How does this fit with the rest of the treatment plan?
Patient Experiences
Desensitization is often described as one of the hardest parts of treatment — it requires confronting the very sensations that cause pain. But families who push through consistently often see dramatic improvement in their child's ability to tolerate touch and resume normal activities.
