Study Summary

The aim of this study is to evaluate the contribution of the vacuum suspension system in an ecological environment on the fitting's comfort compared to the vacuum suspension system inactive system in a multicenter prospective, randomized, double-blind, multiple N-of-1 trial.

In order to assess the therapeutic effect of the vacuum suspension system, given the heterogeneity of the population and the small number of patients eligible for the study, the multiple N-of-1 trial seems to us to be the methodology. The principle is to evaluate intensively and prospectively a small group of subjects, each case being its own comparator.
