Can a simple foot pump ease leg swelling in hospital patients?
NCT ID NCT07760363
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This trial tests a device called the Pedal Pump, which moves the feet for 10 minutes to help reduce lower leg swelling (edema) in hospitalized patients. The study includes 60 adults with edema due to conditions like heart failure, kidney disease, or chronic venous insufficiency. Researchers will check if the treatment is safe, tolerable, and whether it reduces leg swelling compared to a sham device.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pedal Pump device
- What this could lead to
- If effective, the Pedal Pump could offer a simple, drug-free way to reduce leg swelling in hospitalized patients, potentially easing discomfort and improving recovery.
- What could go wrong
- This is an early-stage feasibility study with a small number of participants. The device may not significantly reduce edema, and there is a risk of minor side effects like pain or skin irritation.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Bilateral lower extremity edema of at least mild severity judged by the treating clinician to be due to CHF, chronic venous insufficiency, kidney disease, or other etiologies of fluid overload conditions. * Medically stable * Able to remain in Fowler position for 10 minutes * Patients in the ER, observation, or admitted to the hospital for any period of time; outpatients (specifically CHF clinic patients) * Patients must give informed consent to participate. The patient must be able to read the consent form (in English or Spanish) or give consent after the form is translated for the patient. Exclusion Criteria: * Patients using a hospital bed which has the scale on the foot board * Lymphedema (interstitial protein-built fluid) * Lipedema (fat distribution) * Pressure ulcers * Active DVT (i.e. Patients who have signs of acute unilateral swelling must have a documented negative lower extremity venous duplex ultrasound within the current admission before they will be included in the trial.) * Symptomatic peripheral vascular disease * Wounds or infections in the feet, legs, buttocks, or back * Weeping lymphedema or bullous cellulitis * Uncontrolled hypertension (BP\>180/110) in the recent 2 hours * Uncontrolled hypotension (BP \<80/45) in the recent 2 hours * Heart rate greater than 110 or less than 45 in the recent 2 hours * Leg or back surgery in previous 30 days * Known pregnancy * Severe osteoporosis/fracture risk
