Dynamic Performance

• Passive, flexible limitation of plantar flexion 
• Dynamic foot repositioning 
• High stability and low weight 
• Flexible rollover behaviour in the heel and forefoot 
• High level of functionality and durability 
• Pliable calf section
  

The 28U11 WalkOn® lower leg orthosis is especially designed for use by active patients with weak dorsiflexion or paralysis. It flexibly and passively limits plantar flexion and ensures dynamic foot repositioning. The lightweight carbon fiber orthosis is stable and offers high energy return.

Physiological Gait Pattern

The flexible elements in the anterior foot area and the heel make a dynamic physiological gait pattern possible for your patient, both on even and uneven surfaces, while the middle portion of the foot and the calf band are held in place in order to actively support lifting the foot.

Gait analysis studies have shown that, compared to other carbon orthoses with frontal contact in the stance phase, the WalkOn® offers increased stability for the patient. During the swing phase, the orthosis compensates for the missing foot lifter function in an almost identical manner. The improved rollover dynamics can be verified by examining the torque acting on the upper part of the ankle. Near-sagittal torque was measured on the upper part of the ankle in the middle of the stance phase. This relates to a physiological stress on the joints and a high level of comfort.

In addition, the WalkOn® with its removable calf pad stands out with a high level of wearer comfort. The low weight and slim anatomical shape increase compliance and make a dynamic gait at higher speeds possible for your patient. It also ensures that the orthosis will last for a long time. The WalkOn® is easy to put on and take off.
