SensorHand Speed and VariPlus Speed hand prosthesis

Holding and grasping objects

Reacting quickly and grasping

Grasping large and small objects, lightweight and heavy, fragile and robust: combined with myoelectrically controlled arm prostheses, the SensorHand Speed and VariPlus Speed prosthetic hands make it possible for the user to hold objects, grasp and be active. The special feature is that the hands can open for a quick reaction – in real time – similar to a natural hand. This gives you spontaneity and the ability to use our prosthetic hand almost naturally.

Myoelectric prostheses generally respond to the respective muscle signals of the wearer. Up to six control programmes with the SensorHand Speed and VariPlus Speed make it possible to tailor the hand prosthesis to the individual needs of the user – depending on whether the wearer can control one or two muscle signals. The gripping force and gripping speed can also be adjusted.

Quick-release wrist unit

You can turn the prosthetic hand manually by hand for added flexibility.

Speed sensor

A special mechanism provides the extraordinary gripping speed (15 to 300 mm per second).

Plastic caps

Plastic caps on the fingertips provide additional protection for the prosthesis glove from the inside and create a natural feel.

Thumb sensor

Thanks to the integrated SUVA sensors, the thumb sensor of the SensorHand Speed improves secure gripping and holding. It measures force changes (vector forces) and automatically adjusts the grip if the position of the object changes.

Control electronics

The control electronics permit individual adaptation with up to 7 control programmes.



Benefits at a glance

Quick reflexes

At maximum speed, the prosthetic hand opens about three times as fast as comparable prosthetic hands. With a proportional speed of 300 mm per second, you are even able to react quickly while grasping.

Secure hold

The integrated Autograsp feature of the SensorHand Speed helps you when an object you are holding starts to slip. The gripping force is increased in fractions of a second until the grasped object is in a safe position again.

Grasping objects

Gain freedom of movement in everyday life, at work and in your leisure time. You can grasp and hold various objects, regardless of whether they are light or heavy, small or larger.

Different sizes

The SensorHand Speed and VariPlus Speed are available in three different sizes – for men and women. This integrates them harmoniously into the body image.

Flexible in application

No matter whether you require a fitting starting at the shoulder, upper arm or forearm: Your prosthetic hand can be combined with various system components, so that you can use it to best advantage in everyday life.

Functionality

Prosthesis training

The important prosthesis training phase begins for you once you have been fitted with a prosthesis. Making it possible for you to use the prosthesis so it actually helps you in your daily life is the goal. At the outset, an occupational therapist helps you practice movement patterns such as eating or getting dressed. With special exercises, you learn to position the prosthesis correctly to achieve an optimum position for grasping. Once you are sufficiently confident in using your prosthesis, you practice controlling your muscle strength. Items like foam rubber, drinking straws or paper cups help you determine the various amounts of pressure your muscle contractions can produce, and how this affects materials and solidity.

FAQ

  • How do I control my prosthetic hand?

    You control your SensorHand Speed or VariPlus Speed prosthetic hand with the help of myoelectric signals. These signals can be measured on the skin surface as soon as you tense certain forearm muscles. Sensors in the socket called electrodes pick up the signals so that they can be converted and ultimately control the motor that moves the hand. This is how you open and close the hand.

  • How do I learn how to control the prosthesis with muscle signals?

    Training the muscle signals is perhaps comparable to learning an instrument: practicing regularly is very important. If your socket is properly fitted and your musculature is in good condition, you should already see major progress after about 3 months.

  • Can I type on a computer keyboard with the VariPlus Speed and SensorHand Speed?

    While this is of course possible in principle, it does require practice since you operate the keyboard with the thumb.

  • How long will the battery last?

    We recommend charging the battery overnight. It is integrated in the socket and can be removed separately and charged. The battery lasts for one day depending on the activity level and the chosen capacity.

  • Can I open the hand mechanically?

    If the battery is not charged, you can open the prosthetic hand mechanically as well. Your orthopaedic technician will practice this with you.

  • Are suitable prosthesis gloves available for the two prosthetic hands?

    Yes, Ottobock offers natural and durable PVC prosthesis gloves in a large selection of colours. Your orthopaedic technician will provide you with detailed information.
