Abstract
|
|
|
Thermograpy which maps body surface temperature, has been proposed as a safe, economic and effective diagnostic test for lumbar radiculopathy.
This study involved the relative value of digital infrared thermographic imaging as compared to CT-myelography and electromyogrphy in the examination of 44 patients with low back pain who have received conservative treatment for more than 3
months
after
industrial accident.
@ES The results were as follows:
@EN 1) In comparing CT-myelography with the electromyography and digital infrared thermographic imaging in lumbar herniated nucleus pulposus, there was a slightly better percentage of agreement between the CT-myelography and the
electromyography(89%)
than exists with digital infrared thermographic imaging.
2) Of 10 patients with specific nerve root compression due to lumbar herniated nucleus pulposus on CT-myelography, electromyography was abnormal in 9 patients but digital infrared thermographic imaging was abnormal in only 7 patients.
Thermography, though a simple and less invasive procedure with a potential of usefulness for detecting lumbar herniated nucleus pulposus, appears to have limitation in differentiating the exact nerve root and need to be supplemented by other
electrophysiologic tests.
