Select the true statement concerning phantom limb pain.

• A. Most phantom limb pain becomes more severe with time
• B. Most amputees do not experience phantom limb pain
• C. Nerve blocks may be used to treat phantom limb pain
• D. Trauma amputees have a higher incidence of phantom limb pain than nontrauma amputees

Answer: (C)

Phantom limb pain starts after an amputation when the nervous system continues to generate or amplify pain signals from the missing limb, driven by changes in peripheral nerves and central processing in the brain. Because peripheral input can help drive this pain, blocking those signals can reduce the aberrant activity and lessen pain, making regional or neuraxial nerve blocks a useful treatment option in many cases. Nerve blocks can provide temporary relief by interrupting the sensory input from the residual limb, which can dampen central sensitization and abnormal brain activity related to the missing limb. They’re often used as part of a broader, multimodal approach and can also help guide further therapies, such as targeted nerve therapies or neuromodulation, when initial relief helps clarify which pathways are most involved. While the effect may be temporary, the response can be meaningful and inform ongoing treatment planning. The other statements aren’t as accurate. Phantom limb pain is relatively common among amputees, so it’s not correct to say most do not experience it. The course of phantom pain varies; it does not universally become more severe with time for everyone. And while some studies suggest traumatic amputations may have higher rates in certain groups, the data aren’t consistent enough to claim a definitive higher incidence across all populations.
