WalkOn Reaction Plus

Greater stability for the knee joint

People with permanent dorsiflexor weakness depend on a medical aid that lifts their foot while walking.

This is precisely what the WalkOn Reaction Plus does. It helps lift the foot during the swing phase, so that the gait becomes safer while the risk of stumbling and falling is reduced. The tip of the foot no longer gets caught as easily on small obstacles or uneven ground.

Like the WalkOn Reaction, the WalkOn Reaction Plus also supports the knee joint thanks to its special design, but offers an even higher degree of stiffness. When the foot lowering musculature is impaired as well, you benefit from the high energy return of the orthosis, which is activated during the rollover motion of the foot. You walk more naturally again.

WalkOn Reaction Plus – power to get you moving again

Walk more naturally

The WalkOn Reaction Plus promotes a largely physiological gait. Depending on your current phase in the gait cycle, knee extension and flexion are supported by the special structure (frontal support element) of the orthosis – even when your activity level increases and you require greater support for knee extension. Your gait pattern becomes smoother.

Fewer compensating movements

Compensating movements can lead to signs of wear. The WalkOn Reaction Plus can reduce these through its high energy return. You walk more symmetrically, because the orthosis stores energy at heel strike and releases it again during the rollover movement of the foot.

Enhanced safety

Your safety is increased because the WalkOn Reaction Plus supports and lifts your foot in the swing phase as you walk. The risk of catching the tip of your foot, for example on carpet edges or uneven ground, is reduced.

Use regular footwear

The orthosis fits in any shoe that provides support. You only need to make sure that the shoe has a reinforced heel. To put on the orthosis, position the WalkOn Reaction Plus in the shoe and then slide your foot in.

Lightweight and discreet

The WalkOn Reaction Plus is lightweight, slim, and discreet under clothing. A shin pad makes it even more comfortable for you. 

Robust and durable

The WalkOn Reaction Plus is especially robust. It has proven its durability in tests and long-term functional testing.
