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

<table>Numerical rating scale (mean ± SEM) of patients with chronic neck pain and chronic lower back pain at baseline (pretreatment) and after 2 weeks (posttreatment). Patients in the neck pain treatment group (filled circle) as well as in the lower back pain treatment group (filled square) showed a significant treatment effect compared to the controls (open symbols). <i>P</i> values are indicated as *<i>P</i> &lt; .05, ***<i>P</i> &lt; .001.</table>
