Microprocessor-controlled knee for children
Above-knee prosthetic solutions that aim to adapt to children's walking with the help of sensors and computerized control.
What is a microprocessor-controlled knee for children?
A microprocessor-controlled knee is a knee system used in above-knee prosthetic fittings that combines sensors, a computerized control unit and hydraulic components. By continuously sensing walking, it aims to adjust the resistance of the knee joint according to the situation and to come closer to a more natural movement.
When assessing these systems in children, growth and development, activity level, safety requirements and daily life habits are important. Which system is appropriate is determined individually by the specialist physician and team, taking the child's clinical condition into account.
This page is informational content that introduces the topic in general terms; it does not promote a specific product or brand.
Working principle
The sensors in the knee system detect the phases of the step, speed and loading. The control unit evaluates this information and aims to decide, according to the situation, when the knee will provide support and when it will move more freely.
This approach aims to support safety during standing and the stance phase, and to provide more fluent movement during the swing phase of the step. The settings are adapted to the child's walking by the specialist team, and growth-related changes are monitored with regular check-ups.
- The aim is to support safety during the stance phase.
- A more fluent step is supported during the swing phase.
- Settings are reviewed regularly according to the child's development.
What does it aim for in children?
The headings below introduce the general functions of these systems; the contribution of each feature for the child is assessed individually.
Stance safety
Controlled behavior of the knee during standing and the stance phase aims to support safe movement in daily activities.
Play and movement
It is intended to support the child's daily mobility by adapting to different speeds and surfaces.
Balance support
The knee responding to sudden changes detected during walking may help maintain balance.
Adapting to development
Monitoring growth-related changes with regular check-ups helps the system remain appropriate.
Participation in activities
The aim is to support participation in daily activities and age-appropriate activities.
General examples from daily life
The headings below give a general introduction to example types of activity; individual results vary from person to person.
Play and movement
Activities such as playing in the garden and outdoors are considered part of daily mobility.
Balance and coordination
Activities that require balance are important in gait training and in supporting development.
Participation in activities
Participation in age-appropriate activities aims to support the child's daily life.
Growth, development and adaptability
In children, prosthetic fitting requires regular follow-up because of growth and development. Measurements, settings and components are reviewed over time according to the child's development. The aim is to maintain support suited to the child's daily life and mobility.
- Growth-related changes are monitored with regular check-ups.
- Settings and components are reviewed according to development.
- Gait training helps the child make efficient use of the system.
Frequently asked questions
For which children is a microprocessor-controlled knee considered?
Suitability is assessed individually by the specialist physician and team, taking into account the child's above-knee amputation level, growth and developmental status, activity level, safety requirements and general health.
What is the difference from a mechanical knee?
Mechanical knees provide balance and support through hydraulic/mechanical mechanisms; microprocessor-controlled knees, on the other hand, aim to adapt to the situation by sensing walking through sensors and computerized control.
What happens as the child grows?
Because of growth and development, measurements and settings may change over time. For this reason, regular check-ups and adjustment when necessary are planned by the specialist team.
How does the process begin?
The process begins with a prescription or medical report issued by a specialist physician and continues through the stages of assessment, measurement, fabrication, fitting trial and gait training.
