Myoelectric (bionic) hand system
Electronic hand prosthesis solutions that aim to convert electrical signals from the forearm muscles into finger movements and can be adapted to different grip patterns.
What is a myoelectric (bionic) hand system?
A myoelectric hand is a type of upper limb prosthesis powered by electric motors that detects electrical signals (EMG) from the forearm muscles through surface electrodes and converts these signals into finger movements. The aim is to help the person manage hand functions such as grasping and releasing with their own muscle control.
These systems are available with different grip patterns, finger structures and control options. Which structure is suitable is evaluated by the specialist physician and team, taking into account the person's amputation level, muscle signal capacity, daily living needs and goals.
Key functions
The headings below introduce the general functions of this product group; the contribution of each function to the person is assessed individually.
Multiple grip patterns
The aim is to be able to switch between several grip patterns for different objects and tasks.
Control by muscle signal
Signals from the forearm muscles are evaluated to manage the opening and closing of the hand.
Individual finger movement
Motorized finger joints aim to adapt to the shape of the object being held.
Adjustable grip
Grip speed and force can be adjusted to the person according to fragile and sturdy objects.
Variety of everyday grips
The aim with myoelectric hands is to be able to hold the different objects encountered in daily life safely. Different grip patterns can be defined for a glass, cutlery, a phone or small objects, and it is possible to switch between them during use.
- Grip patterns that can be defined for different tasks
- Adjusting grip speed and force to the person
- Check-ups after fitting and readjustment when necessary
Finger and hand design
The motorized finger joints and the overall structure of the hand are designed with both function and appearance in mind. Optionally, cosmetic gloves close to different skin tones can be used as an option considered according to appearance preference.
