帯状疱疹後神経痛に対する低出力レーザー治療の効果

抄録

About a period of 3 years, 50 cases of postherpetic neuralgia (PHN) were treated by low power Ga-Al-As laser therapy. The rapid efficient ratio of pain releaf from PHN was 90% and the long period efficient ratio was 90%.
Age of the onset influenced prognosis of PHN. The patients who showed slight effects of laser therapy for pain releaf were predominantly in old populations.
Laser therapy showed high effects except for the patients whose PHN lesion was on the abdominal region.
And laser therapy showed high effects in the patients whose treatments were started within 3 months after the onset of PHN while laser therapy showed slight effects in the patients whose treatments were started more than 3-6 months after the onset of PHN.
