Vari-Flex® XC Rotate

HC040014

Vari-Flex XC Rotate combines the established Flex-Foot® attributes of energy return and smooth roll-over, with valuable shock absorption and rotational capabilities.

Lightweight and easy to fit, the foot incorporates a torsion cell, which helps to reduce rotary forces on the knee joint and shear forces on the residual limb. The dual carbon keel lessens the impact of vertical forces, while the EVO feature helps to enhance stance control and roll-over motion, boosting overall walking comfort.

Designed to accommodate hiking and other high impact activities, as well as level ground walking, Vari-Flex XC Rotate is ideal for active people who want to use a single, lightweight foot for a wide range of everyday activities.

Impact Levels

Impact LevelExample

Low Impact

Daily activities involving gentle, steady walking with the use of a walking aid.

Example: Moving around at home, modest walking in the community.

Moderate Impact

Daily activities involving average walking with the ability to vary speed or walking pattern.

Example: Going to the shops, confident outdoor walking.

High Impact

Daily activities involving fast walking, jogging and climbing stairs.

Example: Heavy-lifting, manual labor, recreational sports.

Vari-Flex® XC Rotate™ Features

Active Tibial Progression

Active Tibial Progression

Vertical forces generated at heel contact are stored and translated into a linearmotion described as Active Tibial Progression. This action reduces the need toactively push the body forward using the contralateral foot and also equalizesstride length.

Benefit: More natural gait and reduced walking effort.

CARBON-X® Active Heel

CARBON-X® Active Heel

The Carbon-X Active Heel stores the energy during loading response as the amputee transfers his or her body weight onto the prosthetic foot. Energyis gradually released from the heel providing optimal return for forwardprogression of the limb.

Benefit: Reducing impact to the joints and residual limb thus increases comfort, reduces joint and limb damage.

EVO™

EVO™

The EVO (Energy Vector Optimization) feature is generated by controlling how the ground reaction force is transferred to the prosthetic foot. Each step is optimized through the magnitude, placement and direction of forces for maximum efficiency. EVO enables the amputee to develop the most natural gait progression possible which reduces fatigue and puts less pressure on the sound side.

Benefits: Fluent roll-over which mimics natural gait progressionReduced fatigueEffortless control of the ankle during stance phaseLess pressure on the sound side Less pressure on the lower back

Full Length Toe Lever

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.

Proportional Response

Proportional Response

The layering of carbon fibre, optimised through extensive computer analysis and mechanical testing, ensures that the deflection of the carbon fibre 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.

Rotation

Rotation

Trunk rotation is essential for good gait dynamics. If rotation is limited by loss of joints and the prosthetic interface, gait dynamics and comfort are compromised. Rotational forces are translated to more proximal joints and to the residual limb. Rotary torque absorbing components assist inrestoring rotation thus improving joint health, comfort and gait dynamics.

Benefit: Supports normal gait dynamics, reduces risk of joint damage, and improves residual limb comfort within the socket interface.

Split Toe

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.

Vertical Shock Pylon

Vertical Shock Pylon

The vertical shock pylon reduces impact to the residual limb, joints and lower back during daily activities. It also ensures a more energy-efficient gait by minimising vertical displacement of the centre of gravity.

Benefit: Protection of joints, the spine and stump by reduction of the shock loading.
