Prosthetic legs used after above-knee amputation include different systems that mimic the knee joint. One of these is electronically controlled prosthetic systems, that is, prosthetic systems with a microprocessor knee joint. This content aims to provide general information about this type of prosthesis.
What is a microprocessor knee joint?
Prostheses with a microprocessor knee joint are devices that contain sensors placed in the knee area and an electronic control unit. The sensors continuously measure data such as the speed and angle of the step and the ground conditions. The control unit evaluates this data and adjusts the knee's resistance according to the phase of gait.
The aim is to help the user achieve a more balanced and controlled gait.
General features
Prostheses of this type may often include the following features:
- Electronic control intended to adapt to changes in walking speed
- Systems aimed at offering support in different situations such as level ground, slopes and stairs
- Operation on a rechargeable battery
- Resistance to certain conditions (within the limits stated by the manufacturer)
The technical features and conditions of use of each device vary by model and manufacturer. You can find a detailed breakdown of these features in the article on features of microprocessor knee joint systems, and a general definition of the system in what is a microprocessor knee joint.
Who may it be suitable for?
The choice of prosthesis type is determined according to the person's amputation level, general health, mobility level and daily living needs. The appropriate prosthesis is selected and fitted in line with the relevant specialist physician's assessment and prescription/medical report. Adjustment of the device and training in its use are also addressed as part of this process.
