Otto Bock Kenevo User manual

Kenevo
Activity mode B

Dear Kenevo user,
You have chosen the Kenevo together with your prosthetist. In the Kene-
vo, we use our latest technology for a high level of safety. The knee joint
will therefore support you in everyday life and during rehabilitation
particularly if safety and stability are very important for you.
Three activity modes are available. We would like to introduce mode
B/B+ to you here. The movement pattern in this mode is quite natural.
The Kenevo exes in the so-called swing phase during walking; that is,
when you swing your leg forwards into the air. Mode B/B+ is particular-
ly suitable if you walk for short distances at a slow pace and use wal-
king aids. The basic functions are always active, supporting you espe-
cially when you sit down and stand up.
Your advantages in mode B
• Advanced technology for a high level of safety
• Prosthesis swings through when you walk, including small
steps and with walking aids
• Stumble Recovery Plus: The Kenevo provides high stability as
soon as you make an unexpected movement; the joint is damped
and offers excellent support
• Three active basic functions: supported sitting down,
supported standing up, wheelchair function (optional)
Extra in mode B+
In mode B+ the knee exes slightly in stance phase – just as the natu-
ral knee joint exes a bit. However, exion is limited to 10° here to
support a high degree of stability.

How mode B works
In mode B, the Kenevo swings forwards into the
air (swing phase) when you walk and exes as it
does so. If you roll over the prosthetic leg in the
stance phase aerwards, it immediately provides
you with high stability again.

Make everyday life easier
To ensure a continually high level of safety, the
Kenevo features Stumble Recovery Plus. This imme-
diately increases the resistance when you make an
unexpected movement and want to stabilise your-
self with the prosthetic leg. Three basic functions
also make your everyday life easier: supported sit-
ting down, supported standing up and the optional
wheelchair function. They are active at all times.
• Supported sitting down
The Kenevo automatically detects when you sit
down and assists you. You can place weight on the
joint and still sit down in a slow, controlled manner.
Your hands are free as you do not have to stabilise
yourself. The Kenevo supports you.
• Supported standing up
You can also place your full weight on the Kenevo
when standing up and pause while doing so. The
prosthesis detects your movement towards the
standing position and prevents you from falling
backwards.
• Wheelchair function
If you use a wheelchair now and then, you do
not need to remove the prosthesis to be able to sit
comfortably. In just one step you can position the
Kenevo where it feels comfortable for you: with the
leg between a slightly exed and nearly extended
position. This means it will not be in your way as
you drive forwards.
The team behind the training
The following training will help you get to know mode B/B+ and familiarise
yourself with it. Please speak with your physician, physiotherapist and
prosthetist before starting. They know you personally and will provide you
with individual advice.
Discuss together which exercises will help you and how oen you can train.
Your tting team will also explain to you how to perform the respective
exercise. You can of course then continue the training at home following
consultation with your team.
We wish you every success – step by step. Please take your time. What you
learn now will become habit and will make your everyday life easier.

1
Initiating the swing phase
Activity mode B
Start Stand in a walking position in front of an exercise ball. The prosthesis is
positioned slightly in front of the other foot.
Exercise • Take a step with the other, rear leg. You will roll over the prosthetic foot
as you do so.
• Then kick forwards against an exercise ball with the prosthetic foot.
• If this works well, you can perform the exercise outside of the bars and
then walk in curves.
Objective Walking with the prosthetic leg swinging through.

3
Flex prosthesis while placing weight on it
2Activity mode B+
Start Stand upright and hold onto the parallel bars. Step into a walking position
with the prosthetic leg in front.
Exercise • Now flex the knee until the entire foot is in contact with the floor.
• Roll forwards over the foot so that your body's centre of gravity shifts
forwards. The knee and hip extend.
• If this works well between the bars, use a walking aid.
Objective You learn to flex the knee slightly while placing weight on it and then
extend it again while walking. This initiates your next step.
Start Stand upright and hold onto the handrail.
Exercise Descending a ramp:
• Start with the prosthetic side. Put the heel down. Place weight on the pros-
thetic side while the other leg takes a step. Let the prosthetic leg flex.
• Walk sideways on steeper ramps.
• Practise standing and stopping on the ramp as well.
Uneven ground:
• Use the flexion of the prosthesis to gain contact between the entire foot
and the floor more quickly.
Objective Use prosthesis flexion to master gentle slopes and walk on uneven
ground.
Flat ramp / uneven ground

Unlocking the knee joint to sit down
Supported sitting down/standing up
4
Start Stand in front of a chair. The prosthesis is positioned
slightly in front of the other foot.
Exercise Place weight on the prosthesis. Bend your upper body far forwards. Move
your hands to the armrests. Shift your pelvis to the back and sit down.
Objective Unlocking and sitting down. Building up confidence in the function.
Start Stand in front of a chair. The prosthesis is positioned
slightly in front of the other foot.
Exercise • Start sitting down. Stop during this movement: You will feel the Kenevo
locking and supporting you. Continue moving backwards: The Kenevo
flexes when it recognises the sitting down pattern once again.
• Start standing up. Stop during this movement: You will feel the Kenevo
locking and supporting you. Continue moving upwards.
Objective Place weight on the prosthesis while sitting down and standing up. This
enables you to switch your grasp from your walking aid to the armrests or
vice versa.
5

Positioning the prosthesis with the wheelchair function
Start Sit in the wheelchair.
Exercise Activation:
• Move your lower leg vertically to the desired position.
Deactivation:
• Use your hand or other foot to move the leg upwards until the Kenevo is
extended. Let go of it again.
• Alternatively, you can put light pressure on the toes, for example by
pressing the foot against a wall.
Objective Increase distance between the prosthesis and the floor when using a
wheelchair.
Flexing the prosthesis while sitting
Start Stand in front of the chair and place your hands on the armrests.
Exercise • Sit down without placing weight on the prosthetic side. The leg thereby
remains extended. The knee joint flexes automatically after you have been
sitting for one second.
• If the knee does not flex automatically, the angle between the prosthesis
and your hip is too large. In this case simply lift the prosthesis slightly.
Objective Flex the knee while sitting without manually unlocking it. An alternative to
supported sitting down.

Battery charge level
• Please remember to charge the Kenevo overnight. This is necessary for its functionality.
• Make charging a habit! In the packaging you will find a sticker which you can put on your bathroom mirror, for example. This
way you will always be reminded to connect the Kenevo to the outlet.
• You can easily check the Kenevo’s charge level by rotating it 180°. The sole of the foot then faces up. Briefly hold the joint still
and wait until you hear beeping signals. One beep means that the rechargeable battery is nearly empty; five beeps means it is
fully charged. If it beeps continually, the joint is not working properly. In this case please contact your prosthetist.
• You can continue using the Kenevo if the battery is empty. Certain functions will no longer work, of course, but it is still safe
and provides stability.
Moisture protection
• The Kenevo is protected against dripping water. This means it is not a problem if the joint comes into contact with a few drop-
lets of water.
• However, the Kenevo is not waterproof. The joint will be damaged if you shower or bathe while wearing it.
• If water does somehow penetrate into the prosthesis, dry the joint and contact your prosthetist.
Please refer to the provided patient information for further, detailed operating instructions.
Your prosthetist will provide you with these.
