A total of 21 people hospitalized with acute pneumonia were enrolled in the study. All patients received medical treatment, including antibiotic medication. In addition, 11 participants underwent "specific osteopathic manipulative treatment for somatic dysfunction.
The study concluded that, "Although the mean duration of leukocytosis, intravenous antibiotic treatment, and length of stay were shorter for the treatment group, these measures did not reach statistical significance. However, the mean duration of oral antibiotic use did reach statistical significance at 3.1 days for the treatment group and 0.8 day for the control group."
