Wars, conflicts, and poverty increase higher rates of disabilities in the less developed world. Many are invisible citizens, forced to deal with discrimination, social exclusion, isolation, and poverty.

According to the International Red Cross, landmine victims come from military actions (13%), playing (8%), fieldwork (20%), traveling (15%), demining (4%), non-military actions (38%), and others (2%).

Only 5–15% of people located in Africa and Middle-East countries require assistive devices and technologies have access to them: production is low and often of limited quality, there are very few trained personnel and costs may be prohibitive.

Our answer:

the objective of prosthetics is to restore, as close as possible, the functional capacity formerly held by a limb deficient person, in the west as in developing countries. High health technological devices can be accessible for all.

This means:

for companies, innovations to bring down prices always more and more without losing the best results, implementing corporate social responsibility projects to donate prosthesis to people who can’t afford it;
for states and all other entities promoting persons with disabilities rights, provide access to devices for all.
