The Empower is an innovation in the field of prosthetic feet. It is equipped with an active ankle joint, making it the only prosthetic foot with powered propulsion.

Only the Empower continues to offer the combination of power, control, and stability:

  • Emulates the function and power of lost muscles and tendons 1,2
  • Provides energy instead of taking it away – even up ramps, hills and stairs 1,6
  • Life-like ankle movement that normalizes userʼs walking gait 4
  • Reduces joint forces which may result in less pain and fewer long-term orthopedic problems 1,2,5,6
  • Adjusts ankle power, resistance, and flexion in real time
  • Provides balance on variable terrain 3

 

Scope of delivery:
(1) 1A1-1 Empower Foot
(1) 2C14 Footshell
(1) SL=SPECTRA-SOCK Spectra Sock
(2) 757B38 Battery
(1) 757L38 Dual Bay Charger

 

Software:

Utilizing tablet-based software, you can customize the Empower Ankle for each individual user. The software and the tablet are delivered together with the first order.
