In a patient with bilateral lower extremity edema that worsens in summer, which OMT technique is appropriate to relieve edema?

• A. Pedal pump
• B. Lymphatic pump
• C. Counterstrain
• D. High-velocity low-amplitude thrust

Answer: (A)

Edema relief in the legs is best addressed by actions that directly enhance venous return and lymphatic drainage from the lower extremities. The pedal pump achieves this by rhythmically flexing and extending the feet, which activates the calf muscle pump and promotes forward flow of venous blood toward the heart. This mechanical movement also helps push interstitial fluid upward, reducing dependent edema, and is especially useful when edema worsens with heat in the summer due to venous pooling. Lymphatic pump techniques can help with edema by increasing lymphatic flow, but for bilateral leg edema driven by venous pooling, the pedal pump provides the more direct, targeted benefit to the legs. Counterstrain is focused on relieving somatic dysfunction at tender points rather than actively moving fluid from the extremities. A high-velocity, low-amplitude thrust addresses joints and articulation, not fluid dynamics, so it wouldn’t be the best choice for edema relief.
