Abstract: The invention relates to apparatus for training, investigation, and re-education, in particular for the neuromuscular system. The invention is mounted on a fixed frame and includes a matched is kinetic work system and a programmable two force drive work system, each comprising a drum, a cord windable on the drum terminating with a handle for grasping by the operator. The invention further includes a return member urging the cord to wind on the drum. A motor with an irreversible stepdown gear is connected to the drum of both systems via a transmission so as to exert a force on the cord depending on its direction and speed of displacement.
