To the Editor: The article by Dr Ghoname and
colleagues1 appears to show that percutaneous
electrical nerve stimulation (PENS) is better than some other modalities as
a temporary treatment for low back pain (LBP). The authors state that patients
selected for this study had chronic "LBP secondary to radiologically confirmed
degenerative disc disease." However, the radiographic degree of disk degeneration
generally does not correlate well with degree of pain; in fact, many patients
with degenerative disk disease have no LBP.
