PROPRIO FOOT^®

HCPROFOO

PROPRIO FOOT is an adaptive microprocessor controlled ankle for amputees of low to moderate impact levels. Motor-powered ankle motion increases toe clearance in swing phase by raising the forefoot, reducing the risk of trips and falls. It also adjusts the ankle angle to changing terrain, providing stable foot placement on stairs and inclined surfaces.

Key Features

Increased toe clearance in swing
Automatic terrain adaptation on level-ground, ramps and stairs
Dynamic carbon foot blade with exceptional roll-over characteristics
Relax-mode for comfortable sitting and chair-exit-mode for easier sit transfers
Integrated battery
Weatherproof
Accompanying Össur Logic app for iOS devices provides:

Simple practitioner setup and adjustments, and printable user activity reports
User adjustable ankle alignment for changing footwear
Selection of user preferences and monitoring of step count and battery charge level

PROPRIO FOOT® Features

Full Length Toe Lever

The full length keel/toe lever matches the length of the sound foot, providing improved support to the prosthetic limb during late stance. It ensures that users spend equal time on the prosthetic foot and natural limb, thus providing improved walking dynamics and reduced impact to the sound limb.

Benefit: Improved walking symmetry and reduced impact to the sound limb.

Heel Height Adjustability

Heel height can be adjusted for various types of shoes to ensure correct alignment. Users can easily change shoes to fit most occasions as the heel height can be adjusted within the given range.

Benefits: Adjustable heel height minimizes misalignment of the prosthesis thus reducing walking fatigue and discomfort experienced with poor alignment.

Proportional Response

The layering of carbon fiber, optimized through extensive computer analysis and mechanical testing, ensures that the deflection of the carbon fiber heel and forefoot components are proportional to the user’s weight and impact level.

Benefit: Customized construction optimizes walking efficiency thus reducing fatigue for the user.

Sandal Toe

Sandal toe foot designs incorporate a split between the first and second toe.

Benefit: More anatomical look for increased visual appeal and more functional compatibility with sandal shoes.

Split Toe

A split toe feature allows the foot to adjust to uneven surfaces, allowing amputees to walk with stability and comfort on uneven ground.

Benefit: Helps to maintain balance, stability and reduces peak impact during loading.

Weatherproof

A weatherproof device can be used in a wet and/or humid environment but cannot be submerged. Freshwater splashing against the enclosure from any direction will have no harmful effect. Dry thoroughly after contact with freshwater. Freshwater: includes tap water. Excludes salt and chlorinated water.
