allodynia
Pronunciation: al-oh-DIN-ee-ah
Pain response to normally non-painful stimuli, often complicating exercise progression in chronic pain rehabilitation.
Full Definition
A clinical condition where normally innocuous stimuli produce pain sensations. In exercise rehabilitation, allodynia presents significant challenges as patients may experience pain from light touch, movement, or mild exercise that would typically be painless. This phenomenon is commonly associated with central sensitization and requires careful modification of therapeutic interventions. Exercise therapists must distinguish between allodynia and normal post-exercise soreness to avoid inappropriate activity restriction or progression. Documentation should specify the type of stimulus causing pain and the patient's response patterns to guide treatment planning.
Usage
Usage note: Distinguish from hyperalgesia, which is increased pain to normally painful stimuli.
