Ankle Ball And Snubber Selection - Blatchford Navigator NAV22LWW Instrucciones De Uso

Clinical Benefits
• Optimized keel allows for more consistent rollover radius of curvature.
• Rollover shape falls within the most energy efficient range for most people.
• Greater stability for low mobility users when moving through stance phase compared to
single axis feet and solid-ankle-cushioned-heel feet.
• Improved inter-limb symmetry of stance phase timing, compared to rigid ankles.
• Reduced sound limb loading, compared to rigid ankles.
For bilateral users, the clinical benefits of this device compared to rigid ankle devices include:
• No loss of stability during standing.
• Easier to walk on uneven ground, on slopes and to walk longer distances.

Ankle Ball and Snubber Selection

The ankle ball and the snubber are color-coded to indicate their hardness.
Use the table to choose an ankle ball and snubber combination that suits the weight and Activity
Level of the user. The letter on the left refers to the ankle ball. For example, WO refers to a white
ankle ball and an orange snubber.
• White (W) = Soft
• Orange (O) = Medium
• Blue (B) = Hard
Notes:
i) Bilateral users might need stiffer snubbers than unilateral users.
ii) Transfemoral users might need softer ankle balls than transtibial users.
