A bionic prosthetic leg is an artificial limb system containing sensors, a microprocessor and hydraulic/pneumatic components, which aims to regulate movement by assessing the user's gait, speed and ground conditions in real time. For this reason, it is also commonly referred to as a microprocessor prosthesis. The aim is to support a more balanced and natural gait pattern during the stance (loading) and swing (step) phases of the gait cycle.
How Does It Work?
The sensors inside the prosthesis measure certain data relating to the user and transmit it to the microprocessor. The microprocessor evaluates this data and adjusts the hydraulic resistance or motor support. In this way, the aim is to adapt the movement to the conditions at each step. The main data measured are:
- Step length and walking speed
- Ground incline and obstacles such as steps
- Standing and balance position
The main components include sensors, a microprocessor, a hydraulic system, a battery and, in some models, personalization via a mobile app. Battery life and resistance to water/liquid contact vary by model.
Who Is It Considered For?
Microprocessor knee joints are generally considered for individuals who have had an above-knee (transfemoral) amputation. They may also be considered for people with bilateral amputation to help support balance. Suitability varies according to the level of amputation, general health, physical condition and daily activity level; these factors are considered together during the patient assessment and appropriate prosthesis selection process.
Which type of prosthesis is suitable is determined in line with the specialist physician's assessment and medical report; fitting and adjustments are carried out by the prosthetist.
General Overview
Bionic prostheses are devices that aim to provide balance and movement support in daily life. Results may vary from person to person, and a regular rehabilitation process is important.
