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 10 cm close to maximum pain of patients with chronic neck pain and chronic lower back pain at baseline (pretreatment) and after 2 weeks (posttreatment). Only patients in the lower back pain treatment group (filled square) had a significant treatment effect compared to patients in the control group (open square). No significant effect could be found in the neck pain group (filled circle = treatment group, open circle = control group). <i>P</i> values are indicated as *<i>P</i> &lt; .05, n. s. (no significance).</table>
