Multiflex – Standard
1 2 The Multiflex foot and ankle provide the activity level 2 user with comfortable multi-axial motion, which enhances stability. The low profile design with sandal toe allows for a more natural appearance.
Key Features
- Multi-axial function
- Low profile
- Sandal toe
Multiflex – Standard Clinical Evidence Reference
Clinical Outcomes using Multiflex feet
- Low stiffness at weight acceptance leads to early foot-flat and greater stability for lower mobility patients14
- No loss of stability during standing with Multiflex than fixed ankle/foot15
- Easier to walk on uneven ground with Multiflex than fixed ankle/foot15,16
- Easier to walk up a slope with Multiflex than fixed ankle/foot15
- Little to no difference in gait mechanics compared to flexible, “energy storing” prosthetic feet17
- Increased prosthetic ankle range-of-motion with Multiflex compared to fixed ankle/foot15,16,18-20
- Increased prosthetic ankle power with Multiflex compared to fixed ankle/foot for bilateral users16
- Prosthetic rollover shape closer to natural biomechanics than fixed ankle/foot18
- Bilateral users can walk longer distances and report “smoother” gait with Multiflex compared to fixed ankle/foot16
- Benefits in mobility for bilateral users15,16,18,19
- Equivalent socket comfort to higher technology, energy-storing feet21
- Improved stance phase timing symmetry with Multiflex compared to fixed ankle/foot20
- Reduced sound limb loading with Multiflex compared to fixed ankle/foot20
- Majority of users rate Multiflex as either “good” or “acceptable”22 and bilateral users prefer Multiflex to fixed ankle/foot16
