The existing shortage of therapists and caregivers assisting physically disabled individuals at home is expected to
increase and become serious problem in the near future. The patient population needing physical rehabilitation of
the upper extremity is also constantly increasing. Robotic devices have the potential to address this problem as noted
by the results of recent research studies. However, the availability of these devices in clinical settings is limited, leaving
plenty of room for improvement. The purpose of this paper is to document a review of robotic devices for upper limb
rehabilitation including those in developing phase in order to provide a comprehensive reference about existing
solutions and facilitate the development of new and improved devices. In particular the following issues are discussed:
application field, target group, type of assistance, mechanical design, control strategy and clinical evaluation. This
paper also includes a comprehensive, tabulated comparison of technical solutions implemented in various systems
