Questions and Answers
Radiculopathies -
correct answer ✅-result from injury to spinal nerve roots
-are commonly caused by: disc herniation, spinal stenosis,
osteophytes, tumors (Schwanoma, metastasis)
-result in pain/ sensory loss in a dermatomal pattern and weakness
in a myotomal pattern (ie multiple affected nerves and muscle
compartments

correct answer ✅results from injury to a peripheral nerve
(compression, entrapment); signs and symptoms (paresthesia,
weakness) are limited to the distribution of the affected nerve
