Orthoses
Changes over time
For centuries, fittings on paralysed lower limbs were consid-
ered extremely complicated. The first functional solutions,
however, were very simple. Elaborate leg appliances with
continuous splints were forged at the start of the 16th century.
Unfortunately these early orthoses did not allow the user to
flex the leg, for example when sitting down.
Orthoses with a knee joint equipped with a lock, which al-
lowed the leg to be flexed, were first built at the start of the
19th century. Otto Bock introduced system splints to the
market in the ‘60s of the 20th century, setting the standard
for orthotics.
�
With the E-MAG Control and E-MAG Active electromagnetic
knee joint systems, Otto Bock has ushered in a new era in
orthotic fittings. Novel materials have resulted in significant
application technology changes in the orthotic field over the
last few years, while new options for manual joint locking
mechanisms also appeared. The electronics and computer
industry has continuously developed smaller systems, so
that it is now possible to integrate electrical components
into an orthosis in order to enhance system functionality
and safety.

E-MAGActive
More mobility and a natural gait pattern
The E-MAG Active is the first electronically controlled knee
joint system with a secure stance phase and free swing
phase that is controlled independent of the ankle or sole
of the foot. An intelligent sensor system measures the leg
position during walking and controls the orthotic joint accord-
ingly. This means that the knee joint is automatically opened
and closed while walking, locking in the stance phase and
unlocking in the swing phase.
The advantage: Because the joint is controlled independently
from the ankle and sole of the foot, even users who have no
ankle functionality whatsoever are able to take advantage
of the functionality offered by this orthotic joint. The E-MAG
Active facilitates a more natural, smoother gait pattern for
the user and therefore improves his or her quality of life.
The E-MAG Active was developed for patients who, due to
a partial paralysis or a complete failure of the knee exten-
sors, are unable to stabilize their knee without compensating
measures. Safe use of the E-MAG Active knee joint system
�
requires certain residual muscle functions or hyperextension
of the knee joint. This guarantees consistent activation of
the swing-through and stance phases.
With its closed design, the E-MAG Active is protected against
external influences such as impacts or tangled clothing. The
joint surfaces form a homogenous, enclosed face even when
the joint is flexed.
Since the system is energy efficient, the battery provides
energy for up to 10,000 steps per day, depending on the
type of activity. We recommend charging the battery each
night in order to avoid possible capacity shortfalls.
The E-MAG Active is suitable for a body weight of up to
85 kg. Although th e knee joint system is controlled on the
lateral side of the involved leg, it is always equipped with a
medial support; this means a joint with the same design is
also located on the inside of the leg.

Enjoying a walk
Peter Hartmann
The odyssey begins in 1989 when Peter Hartmann suffers a severe Achilles
tendon injury during a soccer game. As a result of incorrect diagnoses and
treatments, his right leg is almost totally paralysed. The 48-year-old also suffers
several herniated discs and ultimately even a heart attack.

After numerous operations on his knee and spine, he is no
longer able to stand upright and becomes dependent on the
help of others for day-to-day tasks. “It was a terrible time,”
says Peter Hartmann about the many months he had to
spend in hospitals and rehabilitation clinics. His family was
instrumental in helping him find the courage to face life
during those difficult times.
Peter Hartmann is fitted with an orthosis in 2001. He is
able to return to work and starts reorganising his life. The
67-year-old used to love playing soccer, tennis, and handball.
Now he spends a lot of time with his three grandchildren,
and is actively involved in the local gun club and bowling
league. Since his retirement two years ago, the former de-
tective has been working as a lay judge for Sozialverband
Deutschland and helping others experiencing difficulties in
their lives. Long walks with his wife and shared vacations
in the caravan are also possible once again. “All this would
have been unthinkable back then,” says Peter Hartmann.
“Today, I can do almost anything I want.”

E-MAG knee joint systems combine mechanics and electronics
in order to maximize mobility, security, and reliability.
With the E-MAG Active, the locked stance phase and unlocked
swing phase are electronically controlled. An intelligent sensor
system measures the position of the leg during walking and
controls the orthotic joint accordingly.
The locking function of the orthotic knee joint is controlled
via a wireless remote control. A feedback system also keeps
the user informed of the current joint status.

Experience collected with the E-MAG Control contributed
to the development of the E-MAG Active. It is the first elec-
tronically controlled system knee joint with a locked stance
phase and free swing phase that is not dependent on the
ankle and sole of the foot.
The E-MAG Active principle is innovative and consistent: An
intelligent sensor system measures the leg position while
walking and controls the orthotic joint accordingly. The key
advantage: This allows the user to take advantage of the
features offered by the orthosis even if he or she does not
have any ankle functions.
The E-MAG Active offers maximum mobility and safety for
the user. It facilitates a more natural, smoother gait pattern
and therefore improves the user’s quality of life.
During walking, the E-Mag’s electronic system measures leg
position and locks or unlocks the joint depending forefoot
load and knee extension.

E-MAG Control
Enhanced reliabilityand safety
The E-MAG Control is the first knee joint system with an
electromagnetic lock operated by an electronic control unit.
Conventional locking systems use a variety of methods to
deactivate a lock. With all of these systems, the user has to
reach into the vicinity of the knee joint with at least one hand
in order to operate the joint. This is the most unpleasant and
unsafe moment during day-to-day orthosis use.Since the knee
becomes unstable when it is unlocked, the unnatural move-
ment leads to an insecure stance during the unlocking phase.
The E-MAG Control facilitates a secure stance during this
phase. A remote control, which can be used as a hand-held
device or integrated into a crutch, leaves the hands free so
they can help support the body. The E-MAG Control features
a feedback system in the unlocking phase, which sends
a signal when the joint is opened. This allows the user to
consciously prepare for that moment.
19
In addition, the anterior offset of the knee rotation point
causes the knee joint to remain in a secure position until a
movement that involves knee flexion is consciously initiated.
According to user feedback, failure of the knee joint lock
to engage properly when standing up is the most frequent
cause for a fall with an orthosis. Once again, the E-MAG
Control offers a key advantage: It also has a feedback
function for the locking process. As soon as the knee is
extended and the knee joint is locked, a signal commu-
nicates the fact that the joint is secure. Verification or the
subsequent application of manual pressure to the locking
bail is not required. As a result, the system guarantees a
secure stance at all times.
With its closed design, the E-MAG Control is protected
against external influences such as tangled clothing or
impacts that could trigger the joint to unlock or lock. The
joint surfaces form a continuous, enclosed face even when
the joint is flexed.
And because the system is energy efficient, the battery will
last up to 48 hours with 120 knee flexions and four hours of
standing per day. Charging the battery regularly every night
eliminates capacity problems. Since the battery is quick and
easy to replace, using a spare battery is also an option.
A second remote control that allows the joint to be control-
led according to present requirements is also available. A
remote control can be permanently integrated into a crutch.
Please note that only model 22K2/4 crutches are approved
for remote control installation.
The E-MAG Control may be used as a unilateral joint for
a body weight of up to 55 kg, without employing a second
joint on the medial side of the leg. If this is not desirable, a
medial support of the same design may be installed. This
is mandatory for a body weight in excess of 55 kg and is
currently approved for a body weight of up to 85 kg.

Standing for extended periods is unavoidable at her job, but,
in spite of paralysis in her left leg caused by Polio, Semra
does not mind standing up. Sitting still is much harder – un-
less she is focused on her trade, which requires skill and
a steady hand.
Semra Cinpolat has been married for many years. In her
spare time, she dedicates her full attention to her son. “Of
course my husband doesn’t get left out either. The three
of us have a lot of fun together, trying out new games or
romping through the apartment. We are all very active
and like to be out and about.” Sports are very important
to Semra Cinpolat. She cycles regularly, attends a fitness
studio, and goes dancing. She has also discovered the joys
of Nordic walking.
She and her family own their home. Her husband operates
a restaurant on the ground floor. The second floor is rented
out and the family lives on the upper floor. Stairs are no
problem for Semra Cinpolat.

E-MAG Control Questions and answers

2�
The E-MAG Control is the first electronically controlled orthotic
joint system. Through the combination of mechanics and
electronics, it significantly enhances safety for day-to-day
mobility. The electronic control unit allows the orthotic joint
to be locked and unlocked using a wireless remote control
– even for those users who have limited mobility or who are
dependent on forearm crutches. The remote control may
also be integrated into a crutch. Thanks to this option, the
user can always support him or herself with both arms. The
knee joint is unobtrusive and easy to operate.
The E-MAG Control is a system that operates with an
electromagnetic lock. An electronic control unit and remote
control are also required in order to operate the joint. Power
is supplied by a battery.
The electronic control unit is activated using the remote
control. It operates the lock and provides the user with
feedback regarding the knee joint status. This means the
joint position is reported in addition to the operating state.
As a result, the user can rely on the joint in any situation.
The E-MAG Control eliminates the need to manually check
whether the joint is in a secure position. Using a selection
of profiles, the feedback system confirms the position and
state of the joint.
Users can select from the profiles according to the settings
they prefer. Choices include the “Loud Environment” profile
that provides feedback with a tone, light, and vibration, and
the “Quiet Environment” profile that provides feedback with
vibration only. The light signal is mainly intended to verify
electronics adjustments since it is not readily visible under
clothing.

How can I get the E-MAG?
Please consult your orthotist in order to determine if one of
the E-MAG knee joint systems is suitable for you and if an
additional therapeutic benefit for your orthotic fitting can be
guaranteed. If so, you and your prosthetist should discuss
the structure of the orthosis.

Who can use the E-MAG Control?
The E-MAG Control is suitable for users with post-traumatic
conditions, e.g. poliomyelitis, post-polio syndrome, and knee
extensor failure or weakness. Please note that the use of
the E-MAG system is specifically contraindicated for users
who are not able to bring the E-MAG joint into the extended
position by contracting the knee musculature. The user must
be able to bring the E-MAG joint into the extended position
in order to activate the lock. A variety of factors can help
achieve this. Either the user is able to independently extend
the knee joint while standing, or he or she requires help from
the forefoot lever through a specific dorsal stop that can be
achieved using an adjustable ankle joint. Forefoot support
from a long, rigid sole is another option.
Who can use the E-MAG Active?
The E-MAG Active is suitable for users with higher mobility
requirements who were previously unable or unwilling to obtain
an adequate orthotic fitting for various anatomical reasons
such as leg length reduction, valgus / varus deviations in
the knee joint, or a severely atrophic leg. This includes users
suffering from poliomyelitis, post-polio syndrome, or partial
paraplegia with certain physical limitations. The E-MAG Active
was developed for patients who, due to a partial paralysis
or a complete failure of the knee extensors, are unable to
stabilize their knee without compensating measures. Safe
use of the E-MAG Active knee joint system requires certain
residual muscle functions or hyperextension of the knee joint.
This guarantees consistent activation of the swing-through
and stance phases. The E-MAG Active may also be used
with orthoprostheses.
