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

<table>Scores of the Northwick Park Neck Pain Questionnaire (NPQ) and Oswestry Disability Index (ODI) (mean ± SEM) of patients with chronic neck pain and chronic lower back pain at baseline (pretreatment) and after 2 weeks (posttreatment). Patients of the neck pain treatment group (filled circle) had significantly lower neck-pain-related disabilities after 2 week treatment compared to patients in the waiting list control (open circle).  No such effect could be detected in the ODI in lower back pain patients (filled square = treatment group, open square = control group). <i>P</i> values are indicated as *<i>P</i> &lt; .05, n. s. (no significance).</table>
