The aim of study carried out to determine the effects of myofascial release on the cranial arteries velocity from November 11, 2001 to March 29, 2002 the objects were 10 patients who having the tension-type headache at H-hospital This research compared with measure the mean flow velocity middle cerebral artery, posterior cerebral artery, vertebral cerebral artery. Result obtain were as follows; 1. Middle cerebral artery blood velocity between pre treatment and after treatment for 10days experiment was significantly increased 9.76cm/s(p<0.05)in right, 4.88cm/s(p<0.05)in left. 2. Posterior cerebral artery blood velocity between pre treatment and after treatment experiment was difference 6.35cm/s(p<0.01)in right, 5.14cm/s(p<0.01)in left, between pre treatment and after treatment for 5days experiment was 11.48cm/s(p<0.01)in right, 10.74cm/s(p<0.01)in left, between pre treatment and treatment for 10days experiment was 12.92cm/s(p<0.001) in right, 12.68cm/s(p<0.001) in left. 3. Vertebral artery blood velocity between pre treatment and post treatment experiment was difference 4.48cm/s(p<0.05)in right, 6.10cm/s(p<0.05) in left, between pre treatment and after treatment for 5days experiment was 12.50cm/s(p<0.001)in right, 14.40cm/s(p<0.001)in left, between pre treatment and after treatment for 10days experiment was 14.70cm/s(p<0.001)in right, 13.90cm/s(p<0.001)in left.
