2 WalkOn Flex WalkOn WalkOn Trimable WalkOn Reaction WalkOn Reaction plus One range Many different applications The WalkOn product range allows you to address the specific needs of each patient. A variety of conditions and degrees of paralysis in the lower extremity can be treated. The primary feature of the WalkOn orthoses is that they are dynamic a particular benefit for patients with permanent dorsiflexor weakness. 2 Ottobock WalkOn product range

3 WalkOn Reaction junior The products in the WalkOn range are made of carbon fibre prepreg material or a glass/carbon fibre composite. The energy-return properties of the composite material effectively support a physiological gait even when walking speeds and loads are varied. The medial attachment in the longitudinal arch, the dorsal or spiral spring and the support elements facilitate different functions of the orthoses. The elongated frontal element of the WalkOn Reaction also supports users in the frontal and sagittal planes. This provides effective support, especially for patients with additional weakness of the plantar flexors. The WalkOn Reaction junior is a special solution for children. It was developed especially for use in combination with other orthoses and is available from size 24 and up. The ergonomic design of the WalkOn orthoses means they are discreet and inconspicuous to wear. And the climate-regulating pads ensure a high level of wearer comfort. WalkOn product range Ottobock 3

4 WalkOn Flex Art. no. The WalkOn Flex lifts the foot and facilitates a relatively high level of mobility. Indications The orthosis can be used for dorsiflexor weakness, including with mild spasticity, for example following a stroke or traumatic brain injury, for multiple sclerosis, neuromuscular atrophy or isolated peroneal paralysis. It is particularly recommended in cases where dorsiflexion capacity decreases following sustained activity (muscle fatigue). The WalkOn Flex is suitable for indoor and outdoor use for patients who have a stable ankle joint and no impairment of motor control of the knee. The spiral design allows a certain degree of movement in pronation and supination and natural torsion at heel strike. How it works Enables a largely symmetrical and fluid physiological gait with natural heel strike and controlled rollover in the heel and forefoot area Energy return supports foot movement in the early swing phase and reduces compensatory movements such as hip hike Supports dorsiflexion (ground clearance) Prevents uncontrolled foot contact and foot slap in the early stance phase Promotes external rotation of the foot at heel strike Benefits Physiological rollover Proven high durability Glass/carbon fibre composite for high flexibility Allows forefoot loading for climbing stairs and squatting High level of wearer comfort due to low weight and open heel Calf strap made of climate-regulating padding for improved skin hygiene and wearer comfort Slim, discreet design Easy to don and doff Sole can be trimmed to size Optional 28Z10 lateral pronation strap 4 Ottobock WalkOn product range

5 WalkOn Trimable Art. no. The WalkOn Trimable lifts the foot and also stabilises the ankle joint. Indications The orthosis can be used for dorsiflexor weakness with mild to moderate spasticity, for example following a stroke or traumatic brain injury, for multiple sclerosis, neuromuscular atrophy or isolated peroneal paralysis. The WalkOn Trimable is suitable for indoor and outdoor use for patients with no or only mild impairment of motor control of the knee. Its design also allows for some instability of the knee joint. Axis deviation in the ankle joint can be accommodated by using an appropriate insole. How it works Enables a largely symmetrical and fluid physiological gait with natural heel strike and controlled rollover in the heel and forefoot area Energy return supports foot movement in the early swing phase and reduces compensatory movements such as hip hike Supports dorsiflexion (ground clearance) Prevents uncontrolled foot contact and foot slap in the early stance phase, while providing some support for knee flexion Limits plantar flexion and supination when worn with a sturdy shoe Benefits Proven high durability Carbon fibre prepreg material for moderate energy return Allows forefoot loading for climbing stairs and squatting High level of wearer comfort due to low weight and open heel Calf strap made of climate-regulating padding for improved skin hygiene and wearer comfort Slim, discreet design Easy to don and doff Sole can be trimmed to size Optional 28Z10 lateral pronation strap WalkOn same indication and mode of action but without a trimmable sole WalkOn product range Ottobock 5

6 WalkOn Reaction Art. no. The WalkOn Reaction facilitates dorsiflexion and the use of ground reaction forces to influence the knee and ankle joint. Indications The WalkOn Reaction supports patients with dorsiflexor weakness with no or slight to moderate spasticity. It can also be used for slight impairment of the plantar flexion muscles, for foot deformities that can be corrected with insoles and a lateral support element and for slight impairment of knee extension (for example constant fatigue of the knee extensors during long periods of standing or walking). The indication frequently occurs after a stroke, traumatic brain injury, multiple sclerosis, neuromuscular atrophy or peroneal paralysis. The WalkOn Reaction is suitable for indoor and outdoor use for patients with a high level of activity, who need support for knee extension or flexion in the mid-stance phase and during toe-off or heel strike. The frontal support element allows it to effectively influence the knee joint with the help of the ground reaction force. The support element is noticeably longer than in the other WalkOn orthoses, making it possible to exert greater influence on deviations of the frontal axes in the knee and ankle joint. How it works Enables a largely symmetrical and fluid physiological gait with support for knee extension and flexion, depending on what is needed Its energy return supports toe-off and heel strike, thus reducing compensatory movements such as hip hike Supports dorsiflexion (ground clearance) Prevents uncontrolled foot contact and foot slap at heel strike and supports knee extension during toe-off When standing, the alignment of the orthosis influences the statics in the frontal and sagittal planes In conjunction with the lateral pronation strap, it is possible to reduce varus deviations of the foot and ankle joint and supination of the forefoot. This should always be supported by a corrective insole Benefits Highly dynamic properties (use of ground reaction force) Proven high durability Carbon fibre prepreg material for high energy return Shin pad made of climate-regulating padding for improved skin hygiene and wearer comfort High wearer comfort due to low weight and open heel and the anatomically designed frontal support element Pads and closures are combined: in other words, all fabric parts can be washed and replaced Slim, discreet design (no orthosis in the lateral area of the ankle) Asymmetrical design promotes easy, intuitive handling Sole can be trimmed to size 28Z10 lateral pronation strap for correcting instability in the foot and ankle area included in the scope of delivery 6 Ottobock WalkOn product range

8 WalkOn Reaction plus Art. no. The new WalkOn Reaction plus is the logical extension of the WalkOn Reaction and can be used on patients who require greater stiffness of the dynamic forefoot characteristics. Indications The WalkOn Reaction plus also supports patients with dorsiflexor weakness with no or slight to moderate spasticity. It is suitable in case of additional loss of the foot lowering musculature and/or slight to moderate weakness of the knee extensors (extension of the knee joint against gravity should be possible; muscle strength level 3 according to Janda). The WalkOn Reaction plus is also suitable for foot deformities that can be corrected with the 28Z10 pronation strap and insoles. In addition to the functions of the WalkOn Reaction, the WalkOn Reaction plus is suitable for patients who have a higher level of activity and therefore require greater support for knee extension. The design and other functions are comparable to those of the WalkOn Reaction. We recommend testing the various stiffness levels using the 28T3/4 Fit Kits (page 9) in order to obtain the best possible functionality for the patient. How it works Enables a largely physiological gait with higher stiffness than the familiar WalkOn Reaction. This means that even more effective support for knee extension and flexion can be provided thanks to the special forefoot characteristics and more powerful spring force. Its energy return supports toe-off and heel strike, thus reducing compensatory movements such as hip hike Supports dorsiflexion (ground clearance) Prevents uncontrolled foot contact and foot slap at heel strike and supports knee extension during toe-off When standing, the alignment of the orthosis influences the statics in the frontal and sagittal planes Benefits Spring bar with Dyneema reinforcement Highly dynamic properties (use of ground reaction force) Proven high durability Carbon fibre prepreg material for high energy return Shin pad made of climate-regulating padding for improved skin hygiene and wearer comfort High wearer comfort due to low weight and open heel and the anatomically designed frontal support element Pads and closures are combined: in other words, all fabric parts can be washed and replaced Slim, discreet design (no orthosis in the lateral area of the ankle) Asymmetrical design promotes easy, intuitive handling Sole can be trimmed to size 28Z10 lateral pronation strap for correcting instability in the foot and ankle area included in the scope of delivery 8 Ottobock WalkOn product range

9 WalkOn Reaction junior Art. no. The WalkOn Reaction junior is the new member of the WalkOn range. Based on the WalkOn Reaction plus, it features highly dynamic properties. The ankle-foot orthosis uses the ground reaction force to significantly improve the user s gait pattern. It is geared towards children, who require greater support than that provided by traditional dorsiflexion assist orthoses. Indications Infantile cerebral palsy Dorsiflexor weakness, without or with mild to moderate spasticity Hemiparesis, diparesis Benefits Highly dynamic properties (use of ground reaction force) Carbon fibre prepreg material for high energy return High wearer comfort due to low weight and open heel and the anatomically designed frontal support element Shin pad made of climate-regulating material for improved skin hygiene and wearer comfort Can be combined with additional dynamic anklefoot orthoses All fabric parts can be washed and replaced Sole can be trimmed to size Can be worn with sturdy standard shoes How it works Supports lifting of the foot Promotes dynamic rollover Increases the stride length by improving muscle dynamics Promotes exterior rotation of the foot at heel strike Promotes a physiological gait pattern Reduces the risk of falling Order no.: Article number=side & shoe size Example for ordering: =L24-27 WalkOn product range Ottobock 9

11 Easy fitting of orthoses Sole and pronation strap The orthoses in the WalkOn product range are particularly lightweight and comfortable to wear thanks to their anatomical design. For an optimal fit, the soles can typically be trimmed to size using ordinary scissors. A lateral pronation strap can also be used. Soles easily trimmed to size 1 Before adjusting the sole, place the orthosis on the patient s foot. This allows you to determine the correct distance of the longitudinal arch from the posterior edge of the heel. If the patient is wearing shoes with a removable insole, you can use this as a pattern for trimming the orthosis. Ensure that the sole is correctly positioned as described above so movement of the patient s Achilles tendon is not restricted by the orthosis. 2 Trim the sole of the orthosis as marked. Do not reduce the lateral edge more than is necessary. This is to avoid pressing the medial section of the spring against the medial edge of the foot and inner ankle. Make reductions from both sides only if you determine that the sole should be narrower. All information on how to fit the WalkOn Reaction and the WalkOn Reaction plus can be found in the instructions for use included with the product. Lateral pronation strap for more support The 28Z10 lateral pronation strap offers an additional option to provide the orthoses with further support. It is included with the WalkOn Reaction and the WalkOn Reaction plus and can be ordered as an option for the other orthoses. The principle of the lateral pronation strap is well understood and is still widely used today in the classic Valens shoe and splint. However, unlike this conventional method, the 28Z10 lateral pronation strap is not attached to the shoe, but is instead worn inside it. This allows the user to change their shoes at any time.

Using these trial orthoses, you can determine the right orthosis for your patient in just a short time. For the orthoses that primarily support only dorsiflexion and do not have a direct effect on knee joint function, the Fit Kits consist of pooled sizes, four orthoses in all, that cover all the required function tests. This applies to the WalkOn (28T1N Fit Kit), the WalkOn Trimable (28T1N Fit Kit) and the WalkOn Flex (28T2 Fit Kit). 28T2 Fit Kit The Fit Kits for the WalkOn Reaction (28T3 Fit Kit), WalkOn Reaction plus (28T4 Fit Kit) and the WalkOn Reaction junior (28T5 Fit Kit) each consist of eight orthoses so you can compare all functions and draw the correct conclusions from testing. 28T3 Fit Kit 12 Ottobock WalkOn product range
