Evaluation of Safety and Performance of the Atalante System With Patients With Lower Limb Paralysis

Brief Summary

      The study is a prospective, open, bicentric and observational study. It is conducted to
      assess the safety and performance of the Atalante exoskeleton system with patients with lower
      limb paralysis.

      The principal objective is to assess the performance of the Atalante system in performing
      ambulatory functions with motor complete SCI patients characterized by the success rate in
      performing a 10mWT at the last session of training with the Atalante system.

Study Type


Primary Outcome

The primary endpoint of the clinical investigation is defined by the success or failure at the 10 Meter Walk Test (10mWT) at the latest session.

Secondary Outcome

 Capacity of patient in walking defined by Success / Failure on a 10mWT test at the 6th session.
