About this study
Official title: AK Socket Evaluation : Sub-ischial vs Ischial Containment. Multi-center Randomised Crossover Study
Socket is key to provide comfort and function to lower limb amputees. A new socket, the sub-ischial socket, will be compared to "traditional" ischial containment sockets, based on comfort self-evaluation, and locomotor capacities.
Read the detailed description
Subjects wearing ischail containment sockets will be proposed to enter the research. They will be provided and fitted with a sub-ischial socket. Randomly, they will use one or the other socket for four weeks, then be tested : finctional test and questionnaires. After this testing session, they will use the other socket, and be re-tested accordingly.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Socket evaluationDevice
The subject will wear the socket for 4 weeks, and then reply questionnaires and achieve a 2-minute walking test
