Abstract:

Introduction/Background: Osteopathic medical students are trained extensively in palpatory skills. There are limited studies on the difference in palpation pressure between Osteopathic Medical Students (OMS) and Osteopathic Physicians (OP) during the diagnosis of somatic dysfunctions. Objective: Quantify the amount of pressure exerted when diagnosing thoracic somatic dysfunctions and elucidate any difference in pressure between OMS and OP. Methods: OMS and OP were randomly recruited to diagnose a thoracic somatic dysfunction in the same standardized patient in a seated position. Tekscan FlexiForce Sensors were attached to cotton gloves with the sensing area on the tip of the finger. Participants first palpated the spine without the glove to elicit a diagnosis and then repeated the diagnosis while wearing the gloves to measure the force utilized. Participants first diagnosed the rotational component, then the side-bending component, and finally the flexion/ extension component. Results: Twelve OMS (six first-year students and six second-year students) and eight OP participated. There was no statistically significant difference between the palpation force used by medical students versus physicians. The mean pressure used when diagnosing the rotation portion (6.15 PSI L; 5.84 PSI R) was greater than side-bending pressure (3.36 PSI L; 3.54 PSI R) and flexion/ extension (4.46 PSI L; 4.16 PSI R) pressure for all participants. ANOVA test showed a statistical difference between the three groups for both hands (Left-hand P-value = 0.0013) (Right-hand P-value = 0.0089). Discussion/Conclusion: It was observed that when diagnosing the thoracic spine, there was no identifiable difference in pressure used by physicians and medical students; however, there was a significant difference when diagnosing the rotation portion compared to side-bending and flexion/ extension. Limitations of this study include a small sample size.
