Which of the following is an effect of Manual Lymph Drainage (MLD)?

• A. Decreases lymph flow around blocked areas
• B. Blocks sympathetic activity
• C. Increases contraction frequency of lymph collectors
• D. Eliminates total re-accumulation risk

Answer: (C)

Manual Lymph Drainage works by gently stimulating the lymphatic vessels to move lymph more actively. Lymph collectors beat with intrinsic contractions called lymphangions, and applying light, rhythmic strokes in the direction of drainage increases how often these contractions happen. That rise in contraction frequency boosts lymph propulsion, helping fluid move from swollen areas into the lymphatic system and onward toward the venous circulation. This increased lymphatic pumping is the core effect of MLD.

It doesn’t decrease flow around blocked areas; instead, it enhances overall drainage and can help fluids find alternative pathways past blockages. It doesn’t block sympathetic activity, and it doesn’t eliminate the possibility of fluid re-accumulation—edema can recur, though MLD helps manage it and reduce swelling.
