Introduction: This research corresponds to a descriptive study on innovation of robotic technologies developed in Colombia, applied to the process of rehabilitation in patients with functional loss of the hand due to traumatic events.Materials and methods: two patients were selected: Patient with traumatic cervical spinal cord injury level C6 and patient with posttraumatic stiffness secondary to hand breakage.Results: Using the hand exoskeleton in patients with cervical spinal cord injury improved functionality according to the DASH scale, decreasing pain intensity and reported improvement of their self-esteem and quality of life. In the patient with broken hand after a rehabilitation process assisted by robotic orthotic, functional recovery was evidenced by DASH scale also improvement on arcs joint mobility and pain decreased intensity according to visual analog scale.Discussion: We conclude that the use of robotic orthotic hand improved functionality and decreased pain in both patients. Level of evidence: The purpose of the study is to generate clinical evidence (level III) of the usefulness of robotic orthosis in solving global public health problems associated with this type of disability.
