INFORMATION
1 Description
1.1 Intended Use
The WalkOn Flex is to be used exclusively for orthotic fittings of the lower limbs and is exclusively
suitable for contact with healthy and intact skin.
1.2 Indications and Effects
WalkOn Flex supports the foot at drop foot conditions with no more than mild spasticity, e.g. after
stroke, traumatic brain injury, in multiple sclerosis, neural muscle atrophy, peroneal palsy etc. Es-
pecially appropriate when the ability to lift the foot decreases during activities (muscle exhaustion).
WalkOn Flex fits patients with:
• a stable ankle
• no or only mild impairment of motor knee control
• active patients, walking indoors as well as outdoors
For foot deformities: the WalkOn Flex is indicated when a foot deformity can be corrected through
the use of an additional insole and a lateral stop in combination with a sturdy shoe.
The WalkOn Flex is generally suitable for sports activities, as long as no fast, sudden movements
are executed in extreme stride sequences (e.g. basketball, badminton or riding with high activity).
In any case, activities should be discussed with the patient and a special fitting for high activity
levels realised where applicable.
Effects:
WalkOn Flex provides the user with a more natural gait pattern; a faster and more stable walk.
The toes and foot are lifted up during swing phase (clearance) and "foot slap" is prevented. En-
ergy restoring gives a propel effect at initial swing phase. At heel contact WalkOn Flex provide
the user with a slight outward rotation of the foot.
NOTICE
The WalkOn Flex is a dynamic ankle foot orthosis and must not be used for prevention of con-
tractures etc.
Indication must be determined by the physician.
