CRPS Type I management: which of the following statements is true?

• A. It is characterized by vasomotor dysfunction
• B. It involves demyelination of peripheral nerves only
• C. It is caused by acute infection
• D. It presents with nocturnal pain

Answer: (A)

CRPS Type I is defined by autonomic and vasomotor instability in the affected limb, which leads to changes in skin color, temperature, edema, and sweating due to abnormal blood flow. This vasomotor dysfunction is the hallmark feature, so the statement describing it as such is the true one. The idea of demyelination of peripheral nerves only doesn’t fit CRPS Type I, since it isn’t primarily a demyelinating neuropathy (and Type II would involve a nerve injury). It isn’t caused by an acute infection, as CRPS typically follows injury or trauma rather than infection. While nocturnal pain can occur, it isn’t the defining characteristic of CRPS.
