The Benefit of a Mechanical Needle Stimulation Pad in Patients with Chronic Neck and Lower Back Pain: Two Randomized Controlled Pilot Studies

<table>Pressure pain thresholds (mean ± SEM) at the area of maximum pain of patients with 413 chronic neck pain and chronic lower back pain at baseline (pretreatment) and after 2 weeks 414 (posttreatment). Patients in the neck pain treatment group (filled circle) as well as in the 415 lower back pain treatment group (filled square) showed a significant treatment effect 416 compared to controls (open symbols). <i>P</i> values are indicated as *<i>P</i> &lt; .05. </table>
