In prosthetic legs used after above-knee amputation, microprocessor knee joint systems have been developed to support walking safety and movement control. In this type of prosthesis, gait phases are continuously analyzed with the help of electronic sensors and a microprocessor. Suitability and fitting are determined in line with the relevant specialist physician's assessment and medical report.
How It Works
The sensors in a microprocessor knee joint detect step speed, load distribution and joint angle. These data are evaluated by a microprocessor, enabling hydraulic resistance to be adjusted instantly. In this way, adaptation to different walking speeds and ground conditions is aimed for. You can find the basic definition of these systems in the article what is a prosthetic leg with a microprocessor knee joint, and their working steps in the guide to microprocessor knee joints.
Notable General Features
- Resistance adjustment in the stance and swing phases with a sensor system that monitors gait phases
- Support for more controlled movement on slopes, stairs and uneven ground
- Standing support aimed at balancing load distribution
- Resistance to water and weather conditions in some models
- Companion apps through which battery status and activity modes can be monitored
The Fitting Process
Prostheses with a microprocessor knee joint may not be suitable for everyone. The user's general health status, muscle strength, balance ability and activity level are assessed. Selection of the prosthesis and individual measurements and adjustments are carried out in cooperation between the specialist physician and the orthotic-prosthetic technician. Rehabilitation and gait training play an important role in the adjustment process.
