A controlled comparison between manual lymphatic mapping (mlm) of plantar lymph flow and standard physiologic maps using lymph drainage therapy (ldt)/osteopathic lymphatic technique (olt)

Abstract

Background: Trained practitioners claim to identify the specific direction of superficial or deep lymphatic circulation using a non-invasive technique called Manual Lymphatic Mapping (MLM). MLM is a recent advance in manual therapy, a component of Lymph Drainage Therapy (LDT)/Osteopathic Lymphatic Technique (OLT). Objective: Assess the potential of trained practitioners to palpate superficial lymphatic flow. Method: Each practitioner mapped the sole of the foot of a healthy volunteer, a region never previously studied. The results of the mapping were compared between trained and untrained practitioners and physiologic lymph charts Results: Trained practitioners (n=393) provided significantly more correct mappings (correct answers = 245) than untrained practitioners (n=411, correct answers = 11) (X2 = 329.54, p < 0.05), and OR = 60.20, p < 0.05. Conclusion: Trained practitioners, but not untrained practitioners, mapped pedal flow by palpation, consistent with standard physiologic lymphatic maps. Flow studies, by imaging in individual subjects mapped by palpation, must further test this finding.
