- OBJECTIVES: To quantify changes in gastric and intestinal emptying times in the conscious dog following gastrointestinal acupoint stimulation. MATERIALS AND METHODS: In a randomised, blinded crossover study, six dogs were fed 30×1.5 mm barium‐impregnated polyethylene spheres and underwent: (1) no acupuncture (Control); (2) stimulation of target points PC6 and ST36 (Target) and (3) stimulation of non‐target points LU7 and BL55 (Sham). Abdominal radiographs were assessed immediately after feeding the spheres and every hour for 12 hours and their number in the stomach and large intestines was counted. RESULTS: The number of barium‐impregnated polyethylene spheres found distal to the stomach was less in the Target group compared to the Control and Sham groups between hours 2 and 4, but no differences between groups were seen for the remainder of the treatment period. The number of spheres found within the colon/rectum was less in the Target group compared to the Control and Sham groups between hours 4 and 6, and compared to the Sham group only at hour 7 but no differences between groups were seen after hour 8. CLINICAL SIGNIFICANCE: Acupuncture targeted at the gastrointestinal tract of dogs was associated briefly with slowed gastric emptying and gastrointestinal transit time. This foundational study lays the groundwork for additional studies of acupuncture effects associated with altered physiologic states.
