Abstract:

Hypothesis: Perception of motion can be objectified. The ability to palpate motion improves with level of training. Methods: A six-inch, fluid-filled sphere was attached to a syringe via a rigid conduit. The syringe was mounted to a pump that was programmed to deliver and withdraw fluid over predetermined intervals. With a closed system, fluid was pumped into and out of the sphere inducing various amounts of expansion and contraction. Participants placed their hands on the ball and verbalized what they felt as fluid was introduced or withdrawn. Responses were recorded and correlated with the participants’ level of osteopathic training. Results: Palpation of motion was objectified. First-year medical students and residents are able to correctly identify motion better than physicians. Conclusion: The ability to correctly perceive motion appears to be independent of training. This device proved beneficial in objectifying perceived motion and may assist future students in training.
