Group classification of leg prostheses based on activity level
Your activity level as a prosthesis user determines the structure of your prosthesis. Prostheses for the lower limb (leg prostheses) are divided into different groups according to the Belgian health insurance funds RIZIV. The activity level determines the insurance amount:
Group 1: Cosmetic leg prosthesis
A cosmetic prosthesis is chosen if there is no prospect of walking function. Cosmetic prostheses are therefore made with an emphasis on a beautifully anatomically finished leg that is perceived by the outside world as a real leg.
Group 2: Transfer prosthesis
A transfer prosthesis is provided where there is limited prospect of walking function. Transfer prostheses are only used for short-distance travel, both indoors and outdoors, with the use of walking aids. With a transfer prosthesis, the emphasis is mainly on easy and quick donning and doffing of the prosthesis.
Group 3: Definitive prosthesis
You have limited walking ability, use walking aids, but can move around without help from others. You also take part in social activities outside the home.
Group 4: Definitive prosthesis
You are active and can walk with your prosthesis without walking aids and take part in social activities outside the home.
Group 5: Highly active prosthesis
You are highly active, and your prosthesis must be capable of passing a walking test without walking aids or other support.
Prosthesis users classified in groups 3, 4 or 5 are eligible for a computer-controlled electronic prosthetic knee or MCK–MPK knee, provided they meet the specified conditions. The Amputee Care Centre in Genk (Belgium) is fully equipped with a digital gait and measurement laboratory and specialises in the manufacture of definitive and highly active prostheses.
