Evaluation of ALBA device for upper extremity motor function in adults with subacute and chronic acquired brain injury: a randomised controlled trial protocol in a tertiary clinic of the metropolitan region of Chile

Introduction Stroke is a significant worldwide cause of death and a prevalent contributor to long-term disability among adults. Survivors commonly encounter a wide array of motor, sensory and cognitive impairments. Rehabilitation interventions, mainly targeting the upper extremities, include a wide array of components, although the evidence indicates that the intensity of practice and task-specific training play crucial roles in facilitating effective results. Assisted therapy with electronic devices designed for the affected upper extremity could be employed to enable partial or total control of this limb, while simultaneously incorporating the aforementioned characteristics in the rehabilitation process. Methods and analysis 32 adults who had a subacute or chronic stroke, aged over 18 years old, will be included for this randomised controlled trial aiming to determine the non-inferiority effect of the inclusion of a robotic device (ALBA) to regular treatment against only regular rehabilitation. Participants will be assessed before and after 4 weeks of intervention and at 3 months of follow-up. The primary outcome will be the Fugl-Meyer assessment for upper extremities; secondary outcomes will include the questionnaires Functional Independence Measure, Medical Outcomes Study 36-item Short-Form Health Survey as well as the System Usability Scale. Ethics and dissemination Full ethical approval was obtained for this study from the scientific and ethical review board Servicio de Salud Metropolitano Oriente of Santiago (approval number: SSMOriente030522), and the recommendations of the Chilean law no 20120 of 7 September 2006, concerning scientific research in the human being, its genome and human cloning, will be followed. Ahead of inclusion, potential participants will read and sign a written informed consent form.
