Ten 10 interventions with a program of aquatic therapy method (Ai Chi) and Yamamoto New Scalp Acupuncture (YNSA), were made, twice a week. The control group received the intervention only after the end of the study. Pain intensity was assessed by a visual analogue scale (VAS) and the functional capacity by Owestry functionality Index. Results : There was significant reduction in pain and improvement in functional capacity (p < 0.05) in YNSA and AI CHI and when compared to the control group.
