A recent study performed in Spain has shown an immediate benefit from one adjustment in subjects with mechanical neck pain. A group of 70 patients with neck pain (25 males and 45 females, ages 20-55 years) participated in this study. The subjects were randomly divided into either an experimental group, which received an adjustment, or a control group, which received manual mobilization. The adjustment group showed a significant improvement in neck pain at rest and mobility after application of the manipulation. The control group also showed a significant improvement in neck pain at rest, flexion, extension, and both lateral flexions, but not in rotation. Results suggest that a single cervical HVLA manipulation is more effective in reducing neck pain at rest, and in increasing active cervical range of motion, than a control mobilization procedure in subjects suffering from mechanical neck pain.
