title: The effect of subcutaneous nerve stimulation (SCNS) on pain associated with osteoarthritis of the hip.
abstract: A novel form of subcutaneous nerve stimulation (SCNS) was recently introduced for the relief of chronic pain. We present a study using this form of SCNS applied over the radial, median and saphenous nerves in patients with clinically diagnosed osteoarthritis of the hip. Acceptable pain relief was obtained in 60% of patients receiving stimulation, however, comparable analgesia was achieved in a control group, who received no electrical stimulation through similarly placed needles. We suggest that these results may be explained by the ability of SCNS to evoke a placebo response. The efficacy of the placebo effect and the ethical implications of its use in clinical practice are discussed.
