Abstract: The paper presents an overview of the current strategies in the human robot interaction modalities implemented in robotic rehabilitation systems for the upper limb. An in-depth analysis reveals the potential benefits of the existing approaches in relation to the post-stroke stage of the patient. Using several human body anthropometric models and experimental data collected from a group of patients the motion types and amplitudes, limb segment lengths and weights are calculated. Medical protocols for the rehabilitation of post-stroke patients are proposed in correlation with the latest studies and trials. The experimental and calculated data represent a critical point in the preliminary development of new conceptual structures for robotic assisted rehabilitation to ensure an efficient recovery of the post-stroke patients.
Keywords: human robot interaction, post-stroke robotic rehabilitation, control strategies, medical protocols.
