To the Editor: The article by Dr Ghoname and colleagues1 advocating consideration of PENS in the treatment of chronic appears to have limited generalizability. The patients were relatively young, and therefore the findings may not be applicable to the many elderly persons who comprise a significant group of patients with chronic LBP. In addition, the authors used a visual analog scale to monitor pain response. A 100-point numerical rating scale2 is easier for most patients (especially the elderly) to complete, and is easier for examiners to score.
