The EliteVT prosthetic foot delivers shock absorption, rotation and stability to Level 3-4 users in a cosmetic and compact package. It manages the requirements of both walking and running through balancing biomimetic functionality with our proven spring technology.

  • Activity level 3
  • Activity level 4
  • Suitable for outdoor use

EliteVT Clinical Evidence Reference

Clinical Outcomes using e-carbon feet

  • Safety
    • High mean radius of curvature for Esprit-style e-carbon feet2: “The larger the radius of curvature, the more stable is the foot”
  • Mobility
    • Allow variable running speeds3
    • Increased self-selected walking speed4
    • Elite-style e-carbon feet (L code VL5987) or VT units demonstrate the second highest mobility levels, behind only microprocessor feet5
  • Loading symmetry
    • Users demonstrate confidence in prosthetic loading during high activity6
    • Improved prosthetic push-off work compared to SACH feet7
    • Increased prosthetic positive work done4
  • User satisfaction
    • High degree of user satisfaction, particularly with high activity users8

Improvements in Clinical Outcomes using shock-absorbing pylon/torque absorber compared to rigid pylon

  • Safety
    • Reduced back pain during twisting movements e.g. golf swings9
  • Mobility
    • Reduced compensatory knee flexion at loading response10
    • No reduction in step activity11
    • Blatchford torsion adaptors match the able-bodied rotational range12
  • Residual Limb Health
    • Reduced loading rate on prosthetic limb13, particularly at fast walking speeds14
    • Users feel less pressure on their residual limb15
  • User Satisfaction
    • Patient preference, citing improved comfort, smoothness of gait and easier stairs descent13
