Manual lymphatic drainage (MLD) (Fig. 1) is a therapeutic technique distinct from traditional massage, aimed at enhancing the natural flow of lymph fluid within the body to aid in the removal of waste products from tissues. The lymphatic system, reliant on the peristalsis of smooth muscle cells in lymph vessels and the movement of skeletal muscles, propels lymph toward the heart, integrating it with the cardiovascular system. MLD employs light pressure and rhythmic circular motions, a method developed in the 1930s by Danish doctors Emil Vodder and Estrid Vodder, initially as a treatment for chronic sinusitis and immune disorders. Noticing swollen lymph nodes in patients with chronic colds, the Vodders experimented with gentle hand movements to stimulate lymph flow, later formalizing their technique and disseminating it post–World War II.
