How the geko® T3 works

How the geko® T3 works

After an operation, the one thing that normally keeps fluid moving out of your legs — walking — is the thing you can do least of. Blood and fluid pool in the lower leg, and the ankle, foot and calf swell. For most people that swelling peaks around day six to eight.

The geko T3 is designed for exactly that window.

What the device actually does

  1. A gentle pulse, once every second

    Low voltage, no wires, no sensation of shock.

  2. It stimulates the common peroneal nerve

    A nerve running close to the surface just below your knee.

  3. Your calf and foot muscles squeeze and release

    The body’s natural muscle pump, working without you walking.

  4. Blood moves through the deep veins of the leg

    Venous, arterial and microcirculatory flow all increase.

What “60% of walking” means

Firstkind, who manufacture the device, measure the blood flow it generates in the deep veins of the leg at 60% of that produced by walking. In practice that means a meaningful share of the circulatory benefit of a walk, while you sit in a chair or rest in bed.

What the research shows

  • In a study of patients following forefoot surgery, swelling was significantly reduced four days after the operation, and the device was well tolerated.
  • A 2018 feasibility randomised controlled trial published in Heliyon examined whether the device could reduce oedema forming after total hip replacement surgery.

These studies were carried out in clinical settings. They describe what researchers observed in those groups — not a guaranteed outcome for any individual.

Talk to your clinician

The geko T3 does not replace advice from your surgeon, physiotherapist or GP. If you are recovering from an operation, check with the team looking after you before starting any new therapy — they know your case.
