DMC (Dynamic Mode Control) sets a new standard in myoelectric prosthetics: Grip speed and grip force are controlled proportional to the strength of the muscle signal. 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 the two classical Digital Control and Double Channel Control (Single Site) into one hand. This way the prosthetist may decide which control mode is best suited for the patient. The new Otto Bock System Hands with DMC Plus and Digital Twin Control can be optimized for use with the new Otto Bock Lithium-Ion Energypack.
With a dizzying 300 mm per second opening/closing speed, (over twice as fast as before) and enhanced EMG signal processing, the new “SensorHand™ Speed” has unmatched performance.
In addition, our unique AutoGrasp feature stops objects being held from slipping by monitoring and changing the grip force as needed.
As with the previous hand Sensors recognise before an object being grasped starts to slip and will automatically increase the grip force to prevent the object falling.
SensorHand™ Speed also allows you to use one or two input devices and to select from various control options.
The Best Hand in the World Just Got Better
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 SPEED even more responsive to user's signals. Experienced users say they can't 'outcontract' the hand.
High user acceptance rate because it's quicker to open, change between opening and closing, and 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. Standard slip-clutch allows the wearer to release 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 -4°F/-20° C.

The sizing system for the System Electric Hand for adults and the 2000 Electric Hand for children has proven itself effective. The hand covers a wide range of sizes from children right through to adults.
The new Otto Bock size 7 System Electric Hand, closes the gap between the children’s 2000 Electric Hand and the System Electric Hand. It is also suitable for users with very long residual limbs. Though significantly smaller, shorter and lighter, size 7 nevertheless has the same grip force and grip speed as the other System Electric Hands.
The hand weighs a mere 350 g (including the wrist connection and inner hand) and is 100 g lighter than the next larger size 71⁄4.
Moreover, as it is 33 mm shorter than size 71⁄4, it is also suitable for patients with very long residual limbs. The new System Electric Hand, size 7 is available with the customary choice of wrist connections: the Quick-Disconnect Wrist, the die-casted ring or the threaded stud.
Available with DMC plus® or DigitalTwin® control. Size Seven Hand available in DMC and Digital Twin 8E38=6-R/L7 and =7-R/L7 Quick Disconnect 8E39=6-R/L7 and =7-R/L7 Lamination Ring

The Europeans responsible for the "Cyberhand" have, along with it's scifi-esque moniker, given their creation some scifi-esque capabilities that bode well for amputees and Luke Skywalker wannabees the world over. The bionic hand not only has individually functioning digits, including an opposing thumb for the multitude of actions that require one, but those fingers should be able to feel, yet still only take a relatively small number of nerves to control. It works in much the same way as a real hand; by using synthetic tendons that run through each finger, the artificial hand only needs 6 motors to control motion. So far they've created a touch sensitive prototype, and now it looks like their next task is to attach the hand and fire it up. Though what's really got us excited is the wireless communication between the nerve endings and the hand, opening up a whole realm of possibilities for hot-swapping arm attachments. We think you know where we're going with this.

The Modular Arm System supplied by RSLSteeper is truly a modular system with many interchangeable parts, allowing prosthetists to adapt components from most manufacturers. It is designed for rapid assembly and is light and cosmetically appealing. It requires minimal harnessing. The upper and lower forearm tubes are secured to a four-position, manually locked elbow mechanism. At the wrist, friction control of rotation, flexion and extension are available and an integral friction humeral rotator is also provided. A knurled socket attachment ring can be laminated into the socket during fabrication. A shoulder unit with adjustable friction, flexion and abduction movements can be used for shoulder disarticulation and fourquarter level prostheses. The Modular Arm System is finished with a soft and continuous surface. This finish comprises inner and outer elements. The inner cosmeses is built from four components, a foam cover for the upper arm, a foam cover for the lower arm and two soft foam wedges at the elbow. The arm foams are molded from Plastazote. These foam covers are supplied over-sized so that they can be shaped to approximate the contra-lateral arm. The outer cover is available in a choice of two materials; colored elasticized stockinette or reinforced silicone fabric. The silicone wipes clean with a light application of soap and water and are available in a choice of four colors.
World's most powerful elbowState-of-the-art digital technologyCompatible with all hands, grippers, and wrist rotatorsAutomatically locks and unlocksDozens of control optionsOperates with inputs from Myoelectrodes, Touch Pads™, Servo controls, and switches LTI introduced the Boston Digital Arm System early in 2001.
This state-of-the-art prosthetic system incorporates microprocessor technology for improved performance and optimal patient adjustment. The system uses the same drive mechanism as the Boston Elbow II because of its long history of reliable service. Also, this drive unit provides greater torque than any other powered prosthetic elbow on the market today - a feature most users soon recognize as a significant benefit. The Boston Digital Arm is not just for positioning a terminal device like many other elbow prostheses. This system can perform work, whether it be on-the-job, at home or doing hobbies.
The Boston Digital Arm System has many advanced features and capabilities. It can control up to four other prosthetic devices in addition to the elbow itself. For example, hands, grippers, wrist rotators, shoulder lock actuators, etc. can be operated through the Boston Digital Arm. And, these devices can be sequentially selected and operated by the user through co-contraction switching, a feature no other system can provide. A variety of other advanced control features are also available.
The Boston Digital Arm System is actually a platform for upper-limb prosthetic control. The on-board microprocessor enables the prosthetist to evaluate the patient for suitable muscle sites and then try various control strategies until a suitable one is found. This is done through the proprietary software provided with the system. Through the user-friendly graphical interface screens, the practitioner views the patient’s muscle signals and makes adjustments. If a different control strategy is preferred, he simply down-loads a new strategy to the prosthesis - a 5 second task
