It is well known that exercise is healthy and has several positive effects, both mentally and physically. More than 75% of the population a form of exercise. However, of the group with a physical disability (9% of the population), including people with a leg amputation (almost 2%), only 24% practise a sport. It is estimated that in total there are approximately 20,000 children (under 18) with a physical handicap nationwide, almost three quarters of whom do not exercise. This is partly because additional prostheses, such as sports prostheses, are very expensive (price varies from €3500 to €6500) and are not covered by the basic health insurance. Apart from the fact that exercise can also be a pleasant activity for people with a physical handicap, research has shown that regular physical activity can lead to an improvement in mood, an increase in self-confidence and a better acceptance of the handicap. In addition, exercise can prevent or break through loneliness and has positive effects on physical health. The risk of cardiovascular disease, high blood pressure and osteoporosis will also decrease and overall stamina will increase.

Within this project we focus on stimulating exercise in people with (partial) leg amputation.

Solution

JUMP (JUnior Modular Prosthesis) aims to make exercise more accessible and cheaper for people with leg amputations. To achieve this, an innovative modular prosthesis will be developed in JUMP. This modular prosthesis offers the disabled the opportunity to try out and practice multiple sports with a single (modular) prosthesis.

Unique features

The modular prosthesis is unique and radiates in its simplicity, because the foot is very easy to change by the patient. The cost price of this prosthesis will be considerably lower because the latest materials are used that have a lower cost base than the current prosthesis materials. In addition, only one socket needs to be developed per person that can be connected to multiple feet – making it very easy to practice different sports with the modular prosthesis. As shown in the picture below, the socket will be developed per patient and remains unique per patient. The innovative part of this prosthesis concerns the pylon, where the pylon is adjusted in such a way that there is complete freedom of movement for the foot, and there are several types of feet that can be applied and used without having to change sleeves. Using the JUMP prosthesis, people with leg amputations can perform both everyday activities and a variety of different sports. Within JUMP, three feet will be developed for popular sports – and after the successful completion of the project, the range will be expanded.
