Give yourself a hand

The SensorHand Speed opens and closes almost three times faster than other hands—300 mm a second!

And its Autograsp feature with sensor technology can tell when an object you’re holding begins to slip.

Flex your muscles

The motor makes the DynamicArm elbow twice as fast as other electric elbows—only .5 seconds from extension to full flexion. The elbow is proportional in speed and can actively lift up to 11 lbs (5 kg). It has a static holding capacity of 50 lbs (22 kg), while the Vario Drive clutch helps make it especially smooth when flexing and extending.

Natural and efficient

The elbow’s Automatic Forearm Balance takes advantage of the energy that is stored when the arm is extended and reuses it for flexion. This gives the elbow a smooth, natural swing when you’re walking.

Unlocks easily under load

The DynamicArm unlocks easily when under load, and can be positioned without having to send an unlock signal. This means that you can make fewer compensatory movements, and maintain a more natural posture.

Do the twist!

The wrist rotator is also controlled by your signals, so you can rotate your hand inwards or outwards without having to position it with your other hand.


Hand in glove

The MyoSkin Natural prosthetic glove comes in 6 colors. Made out of multiple layers of PVC, the gloves keep out dust and dirt and matches the natural skin structure down to knuckles and veins.

Quick reflexes

The system reacts very quickly to your signals because it is built on the Axon-Bus technology, which integrates all the electromechanical components and transmits signals almost instantaneously to them.


Reliable power

The Lithium Ion battery delivers reliable, high performance. It powers the elbow joint, the wrist rotator, and the SensorHand Speed hand.


The right therapy is essential

The right therapy is critical for success with the DynamicArm prosthesis and it’s important that you work closely with your therapy team, which may include your prosthetist, a physical or occupational therapist, your doctor—and even your family and friends.

For the best outcome, prosthesis training is divided into three phases that build on each other:

Controls training Therapy aimed and helping you learn how to control the prosthesis.

Repetitive drills Exercises to be repeated until using the hand become second nature.

ADL training How to use the prosthesis to its best advantage for everyday activities.

  • Can patients buy directly from Ottobock?

    Except for certain products available at , patients cannot purchase products directly from Ottobock. Ottobock products are generally prescribed by physicians or clinicians, who provide the product to the patient.

    If you’d like to be fit with an Ottobock product, please talk to your physician or clinician (orthotist, prosthetist, therapist, or Rehab Technology Specialist).

    If you have further questions, please call 800 328 4058 and ask for our Consumer Support Specialist.

  • Can I drive again using the prosthesis?

    This also depends on various factors. Please talk to your therapy team and contact the department of motor vehicles in your state.

  • Can I go back to work with my prosthesis?

    Depending on your occupation, you can go back to work with your prosthesis. If your work involves extreme physical strain, you should let your prosthetist know before the pros¬thesis is fabricated, because the type of stress applied to the prosthesis affects the manufacturing of the socket, as well as the selection of components. Various terminal devices, such as the Ottobock System Greifer may be helpful for specific tasks.

  • Can I ride a bicycle?

    Your ability to ride your bicycle depends on the amputation level and the type of prosthesis you have. The Axon-Bus prosthetic system was developed for everyday use and must not be used for unusual activities, for example, sports with excessive strain and/or shocks to the wrist unit (pushups, downhill, mountain biking) or extreme sports (free climbing, paragliding, etc.). Always refer to the the Instructions for Use manual before wearing your Michelangelo hand.

  • Can I go swimming with my prosthesis?

    Your everyday prosthesis is not suitable for swimming or taking a shower. Talk to your prosthetist about a specialized swimming prosthesis.
