Bionic hand prostheses are electronically controlled devices intended to support hand and finger functions in individuals who have experienced upper limb loss. This content has been prepared for general information purposes.
What is a bionic hand prosthesis?
Bionic (myoelectric) hand prostheses are devices within the scope of myoelectric hand applications that control movement by detecting electrical signals in the user's muscle tissue through surface electrodes. These signals are processed and converted into functions such as opening and closing the fingers, adjusting grip force or, in some models, wrist movement. The aim is to support activities of daily living with functionality close to natural hand movements.
General types and features
Prostheses of different designs are available depending on need:
- Full hand prostheses: Multi-articulating solutions in which all fingers can move. They support tasks such as eating, carrying and grasping.
- Partial hand and finger prostheses: Solutions fitted in harmony with the remaining tissue in cases of loss of a finger or part of the hand; details are explained under partial hand and finger prostheses.
- Multi-articulating (myoelectric) systems: Designs in which each finger can be driven by a separate motor, allowing different grip patterns; the general working principle is covered under myoelectric arm prostheses.
Some systems may offer features such as adjustment via a mobile app, software updates and cover options matched to skin tone. The functions of the devices vary according to the user, remaining muscle strength and lifestyle.
How is the right choice made?
Determining the appropriate prosthesis type depends on factors such as the amputation level, the condition of the muscle signals and daily needs. Bionic hand prosthesis applications are planned in line with a specialist physician's assessment and medical report; fitting and the adaptation process are carried out at an orthotics and prosthetics center.
