We offer a solution for nearly every application and level of amputation. Otto Bock is the manufacturer of our wide range of high quality prostheses, featuring outstanding technology.
Cosmetic Arm Prostheses
Cosmetic Arm Prostheses
Cosmetic Hands
Otto Bock Cosmetic Hands consist of an inner hand and a cosmetic glove. The form, color and surface structure of the cosmetic glove simulate the natural hand in great detail. Choose from 43 models in 18 colors for men, women and children. The glove can be easily cleaned, maintained and serviced.
The foam-formed inner hand guarantees low weight and high stability for enhanced comfort. By using different attachment options, the hand is universally applicable. For partial loss of the hand, a special inner hand is required.
The grip function depends on the construction of the hand mechanism. Cosmetic prostheses are also compatible with passive System Hands. They are opened with the healthy hand and closed independently.
Myoelectric Arm Prostheses
Myoelectric prostheses are electrically powered prostheses controlled by the myoelectrical impulses generated by a user's muscle contractions.
12K100 DynamicArm
The DynamicArm is an electronically controlled elbow joint with continuous gearing. Its vario-gear permits a more natural reproduction of a natural arm movement pattern through the continuous adjustment of gear ratio to the environmental conditions (input signal of the patient, movement phase,load to be lifted). Its harmonious movements combine high precision with speed to provide the patient with more independence in everyday life. The low level of operating noise and the slightly dampened and completely silent free-swing phase support the natural, inconspicuous appearance.
The shape and basic colour of the DynamicArm also match quite well with the human body and allow the amputation to slip into the background of daily life. Silicone elements discreetly divided into various colours dampen noises and shocks, such as those that may be caused when supporting oneself on a rigid surface.
Integrated into an appealing and unobstrusive design with the highest possible function, DynamicArm provides patients with quality of life.
Myobock Below Elbow Prostheses
Myo-electrically controlled upper limb prostheses with their accessories are the kind of fitting with the highest rehabilitation value. They unite optimal outer appearance and high grip force and grip speed as well as many combination and adjustment options.
The Residual Limb
There are 3 major factors that are crucial when designing and optimizing trans-humeral and elbow disarticulation prosthesis, including the following:
- Length of the bony lever arm
- Quality and nature of soft-tissue coverage
- Shape and muscle tone of the residual limb
Assembly
An above-elbow prosthesis consists of:- A single plastic upper arm shell
- An elbow joint usually with incorporated locking mechanism
- A plastic forearm
- A wrist joint
- A terminal device, either a hook or a hand
Elbow-Forearm ErgoArm
The ErgoArm, ErgoArm plus, ErgoArm Hybrid plus and the ErgoArm Electronic plus are four excellent elbow components for the myoelectric fitting of higher amputation levels.
The higher the amputation level, the greater the demands on the fitting technique. The ErgoArm Electronic plus and ErgoArm Hybrid elbow-forearm assemblies give you the tools you need for the myoelectric fitting of high amputation levels.
They offer state-of-the-art technology with the aim of combining low weight and extraordinary function with appealing design. The 12K44 ErgoArm Hybrid plus is recommended for hybrid protheses with a myoelectric hand and a cable-controlled elbow joint. And with its integrated "EasyPlug" cable guide, all electric cables disappear inside the prosthesis so that they are both inconspicuous and protected.
Due to its electronically-controlled lock, the 12K50 ErgoArm Electronic plus can be locked or unlocked with myo-signals as well as with a switch. This happens inconspicuously in fractions of a second and offers reliable loading in any position.
7.4 Volt Upper Limb System for Children
Fittings for children have always represented a major medical technology challenge because children have special requirements in terms of functionality, flexibility and mobility.
The 7.4 Volt Upper Limb Prosthetic System meets the individual needs of various age groups while simultaneously preparing the children for a future fitting with the system for adults. This innovative system for children achieves these objectives. In combination with the Electric Hand 2000, the MyolinoWrist 2000 and the MyolinoSkin Natural glove, it uses myoelectric components from the adult segment in order to establish the foundation for a flowing transition in the prosthetic fitting process. The 12K12 MovolinoArm Friction is the perfect complement to the Otto Bock portfolio for upper arm fittings in children aged 3 to 5 years.
12K12 Friction Elbow
The 12K12 MovolinoArm Friction is available in one size. It is the perfect complement to the current Otto Bock product portfolio since it allows fittings on the right and left side for children aged 3 to 5 years. It is compatible with passive, body-powered and myoelectric arm prosthesis systems. The elbow has one friction setting for humeral rotation and one for flexion/extension of the forearm. These components are easy to adjust by parents. Another advantage is that the elbow is compatible with the components of the 7.4 volt system for children - the 7in1 Controller, MyolinoLink, MyolinoSoft, MyoCharge Integral and MyoEnergy Integral - and therefore clearly benefits from the product advantages of this system.
MyolinoWrist 2000 10V51
The MyolinoWrist 2000 is a mechanical friction wrist joint that supplements the hand system for children. It is only compatible with the Otto Bock Electric Hand 2000. It can be used with all 4 sizes (5, 5 , 6, 6 ) of the Electric Hand 2000 and is suitable for either side. The wrist joint is available with a lamination ring or for bonding into pre-fabricated forearm or elbow components.
MyolinoLink 60X6 / MyolinoSoft 560X3
The 60X6 MyolinoLink is used for the wireless transfer of data between the 7in1 Controller and a PC with Bluetooth functionality. The advantage: There is no need to disassemble the prosthesis. Patient-specific settings can therefore be changed without a cable connection.
In order to offer patient-specific controller settings, setup software is also being used for the first time in a hand system for children. Rather than using specified settings, it works with various parameters such as the patient side, control programme, threshold and gripping speed that can be individually adjusted. This is especially advantageous for children with high mobility requirements.
7 in 1 Controller 9E420
The 9E420=* 7in1 Controller is a control system for the Electric Hand 2000 that processes muscle signals and transmits them to the prosthetic hand. The 7in1 Controller runs on 7.4 volts and offers 7 control programmes, some of which are derived from the system for adults. The advantages are apparent: Children can benefit from the range of possibilities offered by systems for adults, their prosthetic hand can be adapted individually and they are simultaneously prepared for a later fitting with the adult system.
MyolinoSkin Natural 8S20N
Skin Natural prosthesis gloves offer a highly natural appearance. They help to complete the body image, which is of particular importance to children. Skin Natural gloves are very robust and easy to clean. Another important function of the gloves is to protect the prosthesis from environmental influences such as dust, dirt, and moisture.
System Electric Hands
The Otto Bock System Electric Hand combines advanced functionality with maximum comfort. It covers a wide range of needs thanks to the variety of different sizes and integration options.
The result is the Otto Bock System Electric Hand with three-fingertip grip. It consists of the interior system hand, hand shell and the cosmetic glove.
We've created a variety of sizes and connection options for establishing the mechanical and electrical connection to the socket, allowing you to cover a wide range of indications.
MyoHand VariPlus Speed
The MyoHand VariPlus Speed is a new development from Otto Bock. It combines the mechanical characteristics of the SensorHand Speed and the control options of the DMC VariPlus system electric greifer.
At a glance
- Available in 3 hand sizes (7 , 7 , 8 )
- Available with 3 connection options (quick-disconnect wrist, lamination ring, threaded stud)
- High active proportional grip force (up to 100 N)
- High proportional speed (up to 300 mm/s)
- No coding plug (program selection using the 757T13 MyoSelect)
- Grip recognition and grip force build-up via bow sensor
- No thumb sensorMigration of control programs from the DMC VariPlus greifer ? Advantage: Fast digital control program
Thanks to the high gripping strength and speed, objects can be gripped quickly and precisely. With the 757T13 MyoSelect, a total of 6 different programs can be selected and adapted according to your patient?s indications. This permits optimum adaptation to the needs and abilities of the prosthesis wearer.
The elimination of the thumb sensor allows our patient to grip actively and consciously. Items have to be held and positioned by targeted muscle signals since the electronics of the MyoHand do not readjust the grip force automatically. The MyoHand VariPlus Speed is recommended for active patients with a low amputation level in particular. A key advantage of the hand is that the patient can actively build up a grip force of up to 100 N. An optimum selection for our patient can be made from numerous different control programs. With each control program, the speed and build-up of grip force can be optimally adapted to patient requirements using the 757T13 MyoSelect.
DMC plus - System Electric Hand
With the DMC plus - System Electric Hand, our patient can naturally control grip speed and grip force in proportion to their muscle signal with the Dynamic Mode Control (DMC) plus electric hand.
For response characteristics that are even more sensitive, there's the new DMC plus. This control also features a new type of safety mode: After gripping once with maximum force, a slightly higher EMG signal is required to open the hand. This reduces the chances of the hand opening due to unintentional muscle contraction. Digital Twin Control combines Digital Control and Double Channel Control (Single Site) into one hand. This allows you to decide which control mode is best for your patient.
System Electric Hand Digital Twin
The Electric Hand with Digital Twin control combines two classic features in one: digital and double-channel control.
SensorHand Speed
At maximum speed, this hand opens and closes almost three times as fast as a standard System Electric Hand.
Proportional Speed and AutoGrasp Feature
Faster! Proportional speed from 15-300 mm/second. Twice the speed of other myoelectric hands (standard hands run at approximately 130 mm/second). Enhanced EMG signal processing and improved software make the SensorHand Speed even more responsive to user's signals. Experienced users say they can't 'outcontract' the hand.- The SensorHand Speed has a high user acceptance rate because it's quicker to open, to change between opening and closing, and to accumulate grip force.
- The AutoGrasp feature allows the wearer to simply hold an object and avoid wasting energy on monitoring whether the item is slipping or not. AutoGrasp can even be turned off when not needed.
- The standard slip-clutch allows the wearer to release the hand quickly in an emergency.
- Improved design along with a new microprocessor and advanced software make the Speed faster and quieter without having to use possibly damaging higher voltage batteries.
- Increased opening power is designed to overcome any resistance from stiff gloves and handshells.
- Effective at lower temperatures: the SensorHand Speed works normally in temperatures as low as -4F/-20 C.
System Electric Hand size 7
The advanced System Electric Hand size 7 was designed especially for adolescents and adults with very small hands. Though significantly smaller, shorter and lighter, the size 7 still has the same grip force and grip speed as the other System Electric Hands.
Transcarpal Hand
The use of myoelectric components to treat amputations and malformations in the transcarpal region was long considered impossible. Until now. Otto Bock has developed unique solutions for treating especially long residual limbs.
New Perspective for Many Patients
Patients with long residual limbs have a myoelectric option with Otto Bock?s 8E44 Transcarpal Hand.
To create a hand as lightweight and compact as possible, Otto Bock has made the motor 1/3 smaller and repositioned it to take up less room proximally. The result is a hand with the same grip force as comparable adult hands. And to save even more room we've created an innovative new connection technique that uses cable loops instead of a lamination ring. The Transcarpal Hand can be operated with either the DMC plus or Digital Twin control units.
Because many patients with long residual limbs can perform pronation and supination (ulna and radial bones conserved) the relevant joint for this function has been left away. To make sure as many patients as possible can be fit, we offer three standard sizes (7 , 7 , 8 ) in two control variations.
Transcarpal Hand DMC plus
The Transcarpal Hand with DMC plus (Dynamic Mode Control) sets new standards: grip speed and grip force are regulated in proportion to the strength of the muscle signal.
The DMC plus control contains both the original DMC control and the DMC plus mode. The DMC plus mode includes a virtual "hand switch": After gripping once with maximum grip force, a slightly higher signal is required to open the hand. This improves gripping security and facilitates the holding of such things as eating utensils.
Transcarpal Hand Digital Twin
The Transcarpal Hand with Digital Twin control combines two classic features in one: digital and double-channel control.
Endoskeletal Adapter 8R1=*
The Endoskeletal Adapter allows the application of the Transcarpal Hand as a particularly short and lightweight hand with quick-disconnect mechanism for fittings of long residual limbs.
Thanks to the endoskeletal tube system, which is easily cut to the required length, the Transcarpal Hand is also a lightweight fitting alternative for short residual limbs. The Endoskeletal Adapter can be combined with any Transcarpal Hand of the corresponding size.
Skin Natural Gloves
Durable and easy to clean, Skin Natural gloves provide more realistic characteristics due to a multilayered structure that creates an impression of depth. The PVC-based material provides robust features for the gloves, showing high durability compared to other materials. Skin Natural is appropriate for patients wearing myoelectric, body powered, and passive arm prostheses.

Cable-Controlled Arm Prostheses
System Hands
The System Hand is a tremendous choice for either cosmetic or functional needs.
Hooks
For cable-controlled prostheses, a hook can be used as a terminal device instead of a System Hand.
In addition, they are easy to clean and are lightweight (aluminum alloy). Standard and working hooks are available for adults, children and adolescents.
While standard hooks are intended for a general use, working hooks with their robust construction as well as diverse and specialized grip options are particularly well-suited for crafts and carpentry.
Body Harnesses
Otto Bock Body Harnesses allow users to control hand and elbow functions through movements of the residual limb and shoulder.
Greater movement, simple control. Otto Bock Body Harnesses control hand and elbow functions through movements of the residual limb and shoulder.
Body Harnesses 21A35 & 21A36
The Body Harnesses give patients excellent proprioceptive feedback without the hassle of complicated harnesses or constrictive neck straps. Both the BE and Triple-Pull harnesses create continuous movement but don?t require sewing. In addition, the Body Harnesses have hygienic, removable axilla pads and easy to use, adjustable straps.
Upper Extremity Joint Bars
Upper Extremity Joint BarsUpper extremity joint bars are invaluable functional components for certain types of upper extremity orthoses and prostheses.
Accessories
Find all the accessories you need for Otto Bock arm prostheses, from extra batteries, chargers, and electrodes to MyoBoy training and analysis unit for technicians.
Electrodes
The latest development in electrodes. A new electrode design that provides a drastic improvement in sensitivity as well as superior noise filtration making it the clear choice for anyone fitting myoelectrics.
Rotator
The wrist rotator provides electrical rotation of the Otto Bock System Electric Hand or Greifer.
Linear Transducer
Linear transducers transfer excursion via the harness system to allow for proportional control of myoelectric components.
MyoWrist Transcarpal 10V38
The Otto Bock 10V38 MyoWrist Transcarpal enables wrist flexion and extension of up to 40.
Upper Extremity Liners
Silicone ArmLiners provide an intimate fit without irritating the skin. They feature two-way stretch, yet are strong enough to prevent unwanted stretching longitudinally?offering both comfort and security.
Silicone ArmLiner
A versatile and durable solution for upper extremity limb loss. These liners deliver both comfort and security.
The advantages of silicone:
- Temperature resistant from -60 C (-76 F)
to + 200 C (393 F) - Water, sweat and weather resistant
- Odor free
- Good adhesion
The Silicone ArmLiner provides an intimate fit and is skin-friendly. It features two-way stretch, yet is strong enough to resist unwanted stretching longitudinally. The Silicone ArmLiner is also the world?s first liner system specifically designed to meet the requirements of upper extremity prosthetics.
And because a lightweight prosthesis is easier to use and more comfortable to wear, we designed the liner to be as thin and light as possible.
The corresponding 14A1 Lock Set was developed after many years experience in upper extremity prosthetics. It is lightweight, functional and easy to use. The lock was designed to be as short as possible, which is especially important for people with long residual limbs.
Fittings with myoelectric devices require precise positioning in the prosthetic socket. For this reason, the Silicone ArmLiner pin system was designed with only a single ratchet.
Custom Silicone Liners
Custom-made silicone liners can be used whenever standard liners are no longer flexible and dynamic enough to accommodate difficult residual limbs.
The custom fabrication takes the form and soft tissue conditions of the residual limb into consideration to produce optimal contact between the skin and the liner. Custom Silicone Liners are available for both upper and lower extremity prostheses.
