Arm Prostheses

Myoelectric arm prosthesis system

Upper limb prosthetic systems made up of interconnected components that aim to convert signals from the arm muscles into hand, wrist and, where needed, elbow movements.

What is a myoelectric arm prosthesis system?

A myoelectric arm prosthesis is an upper limb prosthetic system made up of interconnected components that detects electrical signals from the muscles of the forearm or upper arm and controls the movements of the hand, the wrist and, where needed, the elbow. The hand, wrist rotation and joint components are brought together to work as a whole through the person's muscle control.

The scope of the system varies according to the amputation level. In below-elbow applications the hand and wrist components are the focus, while in above-elbow applications an elbow joint may also be added to the system. The suitable combination of components is determined by the specialist physician and team, taking into account the person's needs, muscle signal capacity and goals.

Key functions

The headings below introduce the general functions of this product group; the contribution of each function to the individual is assessed on a case-by-case basis.

Integrated muscle control

The hand, wrist and joint components are designed to be controlled as a whole by signals from the arm muscles.

Wrist rotation and positioning

The wrist component aims to help bring the hand to a suitable angle for different tasks.

Components according to level

Depending on the amputation level, hand, wrist and elbow components can be adapted to the system.

Individual calibration

Signal thresholds and control settings are configured according to the person's muscle response.

Control and fitting work

Adapting the system to the individual involves electrode placement, signal measurement and configuring control settings. This work is carried out according to the person's muscle response and is readjusted during use when necessary.

  • Measuring muscle signals and determining electrode placement
  • Configuring control settings according to the person's response
  • Check-ups after use and readjustment when necessary

System components and integration

The hand, wrist and, where needed, elbow components are brought together to work as a single system. The aim is to help movements in daily life be carried out more smoothly and in a more balanced way. Components are chosen according to the person's needs.

Frequently asked questions

Who is a myoelectric arm system suitable for?

Suitability is assessed individually by the specialist physician and team, taking into account the person's amputation level, muscle signal capacity and needs.

How does the system change in above-elbow applications?

In above-elbow applications, an elbow joint may also be added to the hand and wrist components. The combination of components is determined by the team according to the level and needs.

How long does it take to learn to use it?

Control through muscle signals is developed through training and practice provided after fitting. The learning period varies from person to person and is supported by the team.
