Abstract
A study on the effect of low level laser therapy on acute headache syndromes was undertaken. Ten patients with acute vascular headache or occipital neuralgia were treated with low power laser over tender trigger points in the distribution of the second cervical and trigeminal nerves, Each tender point was stimulated for 30-40 s with low level laser therapy. There was a statistically significant decrease in headache when reassessed at 15 min. Although not statistically significant, low level laser therapy also appears to have a beneficial effect on associated autonomic symptoms.
