Activity Level 1 2 3 (4)

This award-winning design continues to add a little magic to prosthetic gait. It cushions shock and shear forces caused by vertical and twisting motion and protects the skin interface from abrasion and discomfort.

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

  • Reduced back pain during twisting movements e.g. golf swings1
  • Reduced compensatory knee flexion at loading response2
  • No reduction in step activity3
  • Blatchford torsion adaptors match the able-bodied rotational range4
  • Reduced loading rate on prosthetic limb5, particularly at fast walking speeds6
  • Users feel less pressure on their residual limb7
  • Patient preference, citing improved comfort, smoothness of gait and easier stairs descent5
