Abstract:
The placebo effect of vibratory stimulation was studied in 72 patients with chronic pain syndromes in a double-blind crossover trial using a vibrator and a "placebo unit". Pain alleviation was reported by 48% of the patients during vibratory stimulation compared with 34% for placebo treatment; statistical significance (p less than 0.005).
