Tuina combined with moxibustion From The Treatment of 15 Cases of Pediatric Enuresis with Tuina & Moxibustion by Song Zhan-lin, Shi Yong Zhong Yi Nei Ke Za Zhi (Clinical Journal of Chinese Medicine Internal Medicine), 1993, #1, p. Ten cases were between 7-10 years old, three cases were 11-14 years old, and two cases were 15-18 years old. Nocturnal enuresis in these patients ranged from slight (one time per night) to severe (multiple times per night). Most children in this study did not have any other obvious symptoms, but five cases had frequent urination during the day. Treatment method: Tuina consisted of supplementing Shen Jing (Kidney Channel) on the pinky 500 times, supplementing Pi Jing (Spleen Channel) on the thumb 300 times, supplementing Fei Jing (Lung Channel) on the ring finger 300 times, transporting Nei Ba Gua (Inner Eight Trigrams), i. Moxibustion was then applied to the following acupoints: Dan Tian (CV 4-6) Shen Shu (Bl 23) Bai Hui (GV 20) These patients were treated one time per day, and five days equaled one course of treatment. In general, patients received 1-2 courses of treatment, although stubborn cases received three courses. Chinese Research on the Treatment of Pediatric Enuresis 161 Study outcomes: Ten cases (67%) were cured, four cases were markedly improved, and one case improved. Tuina combined with internal medicine From The Treatment of 60 Cases of Pediatric Enuresis Combining Chinese Medicinals & Spinal Pinch Pull Technique by Wu Xiao-ju, Huai Hai Zhong Yao (Huaihai Chinese Medicine), 2002, #4, p. Forty-eight of these patients (80%) were between 5-8 years old and 12 cases (20%) between 9-15 years old. All the children were more than three years old, and their course of disease was less than one year. Treatment method: External treatment consisted of the spinal pinch-pull technique. In other words, the practitioner pushed and pinch-rolled up the spine five times and then rubbed with their palm in a circular manner from the top to the bottom of the spine two times. Ten days equaled one course of treatment, and, after a three day interval, the patient continued with the next course of treatment. Internal treatment consisted of the oral administration of Bu Shen Suo Niao Tang (Supplement the Kidneys & Reduce Urination Decoction) which was composed of: Huang Qi (Radix Astragali), 30g Dang Shen (Radix Codonopsitis), 10g Shan Yao (Radix Dioscoreae), 10g Tu Si Zi (Semen Cuscutae), 10g Yi Zhi Ren (Fructus Alpiniae Oxyphyllae), 10g Sang Piao Xiao (Ootheca Mantidis), 10g Wu Wei Zi (Fructus Schisandrae), 6g Jin Ying Zi (Fructus Rosae Laevigatae), 10g 162 Treating Pediatric Bed-wetting with Acupuncture & Chinese Medicine Fu Pen Zi (Fructus Rubi), 10g Ma Huang (Herba Ephedrae), 6g One packet of these medicinals was decocted per day in water until 300 milliliters of medicinal liquid remained. Ten days equaled one course of treatment, and the treatment was continued for three successive courses of treatment. From The Treatment of 32 Cases of Pediatric Enuresis with Spinal Pinch Pull, Moxibustion & Cupping by Li Qiang-hua, An Mo Yu Dao Yin (Massage & Dao Yin), 2000, #4, p. The course of disease was less than three years in 19 cases and more than three years in 13 cases. The enuresis occurred one or more times per night in 16 cases, 1-3 times per week in nine cases, and 1-2 times per month in seven cases. Also in seven cases, the enuresis was increased in amount on cold, rainy days. Treatment method: First, spinal pinch-pull was performed five times from Chang Qiang (GV 1) to Da Zhui (GV 14). During the fifth time, the area was pinched three times (instead of one time) and pulled. One treat- ment was given every day, and 10 days equaled one course of treatment. This treatment was done every other day, and five treatments equaled one course of treatment. In addition, Chinese Research on the Treatment of Pediatric Enuresis 163 moxibustion for approximately 10 minutes was done at Guan Yuan (CV 4) and San Yin Jiao (Sp 6) until the skin was slightly red. One treatment was given every day, and 10 days equaled one course of treatment.
