EchelonVT

Suitable for outdoor use
Activity Level (2) 3 (4)

EchelonVT combines the advanced hydraulic technology of Echelon with an additional rotation and vertical shock absorption element, to reduce the shear forces at the socket interface. This reduces the rate of loading at the socket interface and allows the socket to rotate with the residual limb, rather than against it. This means the user is able to move and adapt more freely, making EchelonVT ideal for taking part in activities such as golf and hiking.

Key Features

  • Rotation and vertical shock absorption
  • Tripod action for conformance and vertical compliance
  • Smooth hydraulic and spring action

Unique & Proven Echelon Technology

The Echelon range sits at the heart of our pioneering prosthetic philosophy which makes our products so popular with users around the world. Created with a sharp focus on replicating a natural and safe walking experience, each product in the Echelon Range has a characteristic to suit different users and their requirements, providing confidence in every step.

 

This not only provides excellent energy storing and release properties but also works in harmony with the range of movement in the ankle to provide a natural and comfortable walking experience. 

 

When walking up slopes, the additional range allows the body to move forward over the foot, reducing energy requirements by making rollover easier. When walking down slopes, the foot complies with the slope without forcing the leg forward, allowing for a more controlled descent.

Hydraulic damping and foot springs produce a visco-elastic response that simulates the behaviour of muscles by storing and releasing energy. When compared to non-hydraulic ankles*, this technology is clinically proven to provide comfort, safety, natural walking, balanced limb loading and overall greater patient satisfaction.

Clinical Compendium

 

Clinical Compendium

Blatchford Biomimetic Hydraulic Technology mimics the dynamic and adaptive qualities of muscle actuation to encourage more natural gait. Multiple independent scientific studies, comparing Blatchford hydraulic ankle-feet to non-hydraulic feet, have shown:

  • Greater comfort, reduced socket pressures
  • Improved safety, reduced risk of trips and falls
  • Smoother, easier and more natural gait
  • More evenly balanced inter-limb loading
  • Greater satisfaction
