P.I.G.R.O.: An Active Exoskeleton for Robotic Neurorehabilitation Training Driven by an Electro-Pneumatic Control

This paper presents the structure and the main innovations of P.I.G.R.O. (Pneumatic Interactive Gait Rehabilitation Orthosis). It is an active exoskeleton electro-pneumatically controlled with 6 DoF (Degree of Freedom) in the sagittal plane. Robotic neurorehabilitation trainings are its main field of application. Some preliminary tests are carrying on with brain stroke and ictus patients.
