A microprocessor knee joint is a prosthetic component that works with sensors and electronic control systems and may be used by people with limb loss at the above-knee level. This article discusses the general working principle of the technology and the assessment process for informational purposes.
Working principle
Microprocessor knee joints contain sensors that detect the position and speed of movement of the leg while walking. The data obtained are processed by a control unit, and the knee's resistance is adjusted in real time. The aim is to provide appropriate support at the different phases of the step.
These systems usually run on a rechargeable battery and can be configured according to the user's gait characteristics. The differences between mechanical and microprocessor knee joints are among the topics taken into account when determining the appropriate component.
Possible contributions
The intended contributions of microprocessor knee joint technology include:
- Support for a more balanced gait on level ground and slopes
- Controlled movement in activities such as going up and down stairs
- Balance support aimed at reducing the risk of unintended buckling during the step
- Supporting the user's independence in activities of daily living
The degree of these contributions may vary from person to person and may not produce the same result for every individual.
Assessment and fitting process
Prosthetic components such as a microprocessor knee joint are selected and fitted in line with a specialist physician's assessment and prescription/medical report. The appropriate component is decided taking into account the individual's limb condition, general health, activity level and expectations. Individual adjustment of the device and regular check-ups are carried out at the center by authorized technical staff.
