Methods The tenderness of anterior superior iliac spine which was the starting point of gluteus medius was taken as the center, i cm around it, 4-8 needle insertion points were fixed. Fire-needle with intensive and deep needling method was applied deeply on the surface of the bone then immediately taken out. The treatment was given once every 3 days, 3 times as a course. Results After 2 courses, 22 cases were fully recovered, 22 cases with remarkable effect, 4 cases without effect, and the total effective rate was 92.5%. Conclusion Fire- needle with intensive and deep needling method has remarkable therapeutic effect.展开更多
