Abstract:

Background: The Dalrymple pedal lymphatic pump (DPLP) is a common osteopathic manipulative treatment (OMT) technique used clinically to increase lymphatic circulation and fight infection. As traditionally taught, “correctly performed” DPLP involves oscillating force applied to the patient's feet at an individualized rate and force combination that produces a visible “abdominal sloshing” motion at the level of the diaphragm. This force has never been measured, but an average DPLP rate of 120 per minute (2.00 Hz) is suggested. Machines such as the AT101 (CIS, Florida) may be capable of replicating DPLP OMT and its physiologic effects for potential use in research and clinical arenas. Hypothesis: Manual and AT101 frequency and force (F&F) can be replicated interchangeably as can the visual (“sloshing”) OMT titration point. Methods: Fifty-one subjects were randomly assigned to 2 groups; an accelerometer measuring F&F in all subjects. Group 1 subjects (n=25) received manual DPLP titrated to create an “abdominal slosh.” They were then placed on the AT101 where machine settings were adjusted attempting to replicate identical F&F measurements recorded during manual DPLP. Finally, the examiner blindly modified machine settings to attempt to recreate the “OMT slosh” on the AT101. Group 2 subjects (n=26) all received an AT101-induced motion using predetermined settings and then underwent a manual attempt to replicate machine-induced F&F. Each was then re-evaluated while receiving traditional DPLP. Results: In group 1, manual DPLP frequency and force averaged 2.23 Hz and 0.27 G, respectively, with successful F&F replication on the AT101 (average= 2.20 Hz at 0.26 G). On the AT101 a visible “slosh” in the same subjects was re-created using an average F&F of 2.18 Hz at 0.29 G. In group 2 subjects, optimal manual DPLP averaged 2.34 Hz at 0.29 G. Machine presettings in group 2 subjects created higher F&F averages (2.47 Hz at 0.42 G); manual F&F replication attempts averaging 2.35 Hz at 0.43 G. Conclusion: While individualized, a traditional DPLP can be performed using an average 0.28 G force at a rate of 135 per minute (2.25 Hz). An experienced operator using an AT101 machine is able to reproduce the F&F used in the manual DPLP as well as its traditional “slosh.” Frequencies and forces in manual- and machine-induced pedal pump are reproducible. Factory settings on the AT101 machine create only a few F&F combinations that were unable to be fully reproduced or sustained by hand.
