Abstract:

Introduction/Background: Conducting Osteopathic Manipulative Medicine (OMM) research poses challenges in maintaining validity due to variations in palpatory skills among researchers, which can skew data in randomized trials. Previous literature shows that efforts to improve intra-researcher reliability, such as involving multiple physicians or establishing detailed guidelines, have shown limited success. Increasing the number of researchers could reduce the study’s validity. Hypothesis: This study hypothesizes that a calibration protocol before initiating OMM research will standardize diagnostic skills, improve assessment proficiency, and reduce variability in investigating techniques. Methods: Nineteen researchers underwent a calibration protocol to qualitatively and quantitatively evaluate innominate and pubic somatic dysfunctions. Researchers were paired with a board-certified OMM physician for identical evaluations. “Passing” calibration required adherence to all protocol steps, 70% accuracy in palpatory findings, and measurements within 15% error. Failing participants repeated calibration or faced exclusion from future participation. Pre- and post-calibration questionnaires assessed self-reported proficiency in OMM techniques on a 7-point Likert scale (1 = Not proficient, 7 = Very proficient). Results: Fourteen researchers passed calibration on the first attempt, and five succeeded on the second. Post-calibration, all achieved proficiency with high inter-researcher reliability, verified by the OMM physician. Pre- and post-calibration surveys showed that self-reported diagnostic confidence increased from 5.9 to 6.2, and treatment confidence rose from 5.8 to 6.8. Discussion/Conclusion: The evidence supports the effectiveness of a calibration in enhancing intra-researcher reliability in OMM studies. As OMM research relies on practitioners’ hands for data collection and treatment analysis, implementing calibration is essential for OMM research to improve study validity in multi-researcher designs. A limitation was the small sample. Future studies should calibrate additional OMM techniques, such as vertebral or cranial evaluations.
