To confirm true nerve compression, one would have to demonstrate the presence of:

• A. Deficits
• B. Pain
• C. Subluxation
• D. Reflexes

Answer: (A)

Deficits in nerve function are the clearest sign that a nerve is truly compressed. When a nerve is compressed, its ability to carry signals to and from the brain is impaired, which shows up as sensory loss or alteration in the nerve’s distribution and/or weakness in the muscles served by that nerve. Pain can accompany compression but by itself doesn’t prove that conduction through the nerve is compromised. Subluxation is not a direct measure of nerve status, and reflexes may be normal or altered for reasons other than compression. So, identifying actual deficits—sensory changes in the dermatome and/or weakness in the corresponding myotome—provides objective evidence that nerve function has been affected by compression.
