According to the power analysis, the population will be utilized as the experiment group and the control group. The measuring tool to be used is the Gastroparesis Cardinal Symptom Index (GCSI) which is the most widely used symptom score questionnaire for gastroparesis. The subjects in the population will each fill out the GCSI initially and again after an two (2) week period to measure their symptoms during a control period. The same subjects will then be treated with global osteopathic manual treatments one (1) treatment every two (2) weeks for four (4) weeks (day 1, 14, and 28). The GCSI will be filled out on the day of the first (1st) treatment (which is the last day of the control period) and then two (2) weeks after the last treatment (day 42). In order to reject the null hypothesis, with a p value of < 0.05 and a power of 0.8, a minimum of ten (10) subjects in the treatment group is required with a treatment effect of 1 or more. A 'Treatment effect of 1' is defined by Cohen's d, where d = mean difference/standard deviation.
