Which modality could be used to decrease sensitivity for CRPS?

• A. Fluidotherapy
• B. Cryotherapy
• C. Ultrasound
• D. Electrical stimulation

Answer: (A)

Desensitization through graded sensory input is a common goal in managing CRPS. Fluidotherapy provides controlled, soothing tactile stimulation while warming the limb. The cabinet bath of heated air and tiny cellulose particles allows the therapist to adjust textures, pressure, and temperature so the patient experiences varied sensory input without sharp pain. This repeated, tolerable exposure helps retrain the nervous system to interpret touch as non-painful, reducing allodynia and hyperalgesia over time. Other modalities don’t offer the same graded, texture-rich exposure. Cryotherapy delivers cold, which can be uncomfortable and may worsen vasomotor symptoms in CRPS for some patients. Ultrasound focuses on tissue heating or nonthermal effects rather than providing progressive desensitization. Electrical stimulation can help with pain relief but doesn’t provide the structured sensory exposure used to desensitize hypersensitive skin.
