[Introduction] Acupuncture has been used in patients with functional digestive symptoms. Acupuncture treatment was used on a patient with upper stomach pain and feeling of fullness accompanied by pain in knee, neck and shoulders. Details of the clinical experience have been written in this brief report and shows improvement in gastric symptoms and increase of normogastria in gastric electrical activities by acupuncture treatment.[Case] A 73 year-old female patient, who was 148 cm tall and 51 kg in weight, complained of some chronic pain at the first medical examination. However, in the 24th treatment, the patient complained of severe stomach pain and feeling of fullness accompanied by 36 points on the gastrointestinal symptom rating scale (GSRS). Therefore, electrogastrograms (EGG) were recorded, as a noninvasive clinical evaluation of gastric function, at 15 minutes before and after the 30th treatment for 10 minutes using the retaining needle technique at bilateral ST36 andST40.[Result] The decrease of GSRS showed improvement of gastric symptoms by acupuncture treatment. After treatment, the percentage of normogastria in EGG increased to 71% from 58%, thus stabilizing theincrease in power spectra.[Discussion] It has been suggested that the increase of nomogastria in EGGs show an improvement of gastric symptoms. Moreover, the patient was told about the positive changes in EGG by an acupuncturist, and explaining that the acupuncture treatment seemed to improve clinical symptoms. Thus, acupuncture treatment contributed to an improvement of symptoms in a patient with stomach pain and feeling of fullness.[Conclusion] Acupuncture treatment induced an increase in percentage of normogastria in EGG power and resulted in an improvement in gastric symptoms of a patient with upper stomach pain and feeling of fullness.
