title: Efficacy of type a botulinum toxin injections and infrared polarized light on treating chronic migraine.
abstract: OBJECTIVE
  To investigate the clinical value of the combination of ultrasound-and-hyponome-guided type A botulinum toxin injection and infrared polarized light on treating chronic migraine.
  
  
  METHODS
  Ninety-one patients with chronic migraine were randomly divided into four groups: in the control group (group A, 22 cases in total), nimodipine was used in the treatment of chronic migraine for two months; in the infrared polarized light therapy group (group B, 22 cases in total), infrared polarized light was adopted in the treatment of chronic migraine for 50-60d; in the botulinum toxin treatment group (group C, 24 cases in total), ultrasound-and-hyponome-guided type A botulinum toxin was injected into frontal, temporal, and occipital muscles in treating chronic migraine; in the joint treatment group (group D, 23 cases in total), ultrasound-and-hyponome-guided type A botulinum toxin injection in group C and infrared polarized light in group B were both used here in the treatment of chronic migraine. Infrared polarized light therapy lasted 50-60d and the time of study lasted six months. The survey would include the conditions of patients with chronic migraine three months before treatment and at one, three and six months after treatment. Patients were asked to fill the MIDAS (migraine disability assessment questionnaire) and were graded on the evaluation scale of life quality, so that the researchers would be able to compare attack frequency, duration of attack, attack severity, the use of painkillers and their recovery from chronic migraine, and then observe their adverse reactions.
  
  
  RESULTS
  Eleven cases dropped out during the treatment, three cases in A group, two cases in group B, four cases in group C and two cases in group D. One, three and six months after treatment, the MIDAS scores in group A, B, C and D were significantly lower than before the treatment. Hence, the differences were statistically significant (p < 0.01). The scores in quality of life rating scale were significantly higher than pre-treatment scores, so the difference was statistically significant (p < 0.01). The MIDAS scores and quality of life rating scale scores in group D were compared with those in group A, B, and C respectively, and the differences were statistically significant (p < 0.05). Two patients were recorded with dizziness, and the dizziness disappeared after two weeks with no treatments at all. Forehead lines and crow's feet of 21 patients shallowed or disappeared in varying degrees after the injection.
  
  
  CONCLUSIONS
  The combination of ultrasound-and-hyponome-guided type A botulinum toxin injection and infrared polarized light on treating chronic migraine demonstrated a significant clinical effect.
