Alter-Ego as an Assistive Robotic Device.

Rövid összefoglaló (regiszter, angolul)

The ALTER-EGO study is a monocentric, observational clinical investigation designed to evaluate the safety, usability, and feasibility of the humanoid robotic platform Alter-Ego as an assistive device in hospital and simulated home-care settings. The system is intended to support healthcare and rehabilitation professionals in the management of patients with Amyotrophic Lateral Sclerosis (ALS). Alter-Ego is an anthropomorphic, wheeled, self-balancing social robot equipped with compliant robotic arms and SoftHand synergistic grippers. It operates in teleoperated, semi-autonomous, or fully autonomous modes and integrates advanced navigation, mapping, object manipulation, and natural language processing capabilities. The robot is not classified as a medical device under EU Regulation 2017/745, as it does not perform diagnostic or therapeutic functions, but provides logistical, communicative, and organizational support. The study is conducted at ICS Maugeri IRCCS (Milan Camaldoli). Participants include healthcare professionals (physicians, nurses, physiotherapists, occupational therapists, speech therapists, and healthcare assistants) and up to 40 hospitalized ALS patients. Patients are not direct operators of the robot but provide experiential feedback through questionnaires and qualitative interviews. A total of 40 experiments are organized into four clusters: Cluster 1 - Telemedicine (Teleoperated or Semi-Autonomous Mode) Within a simulated home-care environment, Alter-Ego supports remote clinical and rehabilitation activities through four specific tasks: Simulated Remote Medical Visit (First Home Transition): A physician conducts a tele-visit via the robot, asking health-related questions, performing visual neurological assessments using cameras and microphones, requesting specific motor tasks, and reviewing vital parameters from home monitoring devices. This task addresses the need for expert supervision during early discharge phases. Assistive Device Training: A physiotherapist and nurse remotely verify and guide the correct use of assistive devices such as non-invasive ventilation systems, PEG, or patient lifters, providing practical instructions to patients and caregivers. Home Environment Assessment: An occupational therapist uses the robot in semi-autonomous mode to map the domestic environment and, in tele-guided mode, visually inspect spaces to identify architectural barriers and optimize assistive device placement. Telerehabilitation: Physiotherapists and speech therapists use the robot's audio-video interface and display to conduct remote rehabilitation sessions and functional evaluations, providing visual and verbal feedback. Cluster 2 - Delivery Services (Autonomous Mode) The robot autonomously transports small items within the hospital ward, including medical records, blood collection kits, rehabilitation tools, and small food or beverage packages. Cluster 3 - Guidance and Welcome Assistance (Autonomous Mode) Alter-Ego presents ward service information to newly admitted patients and provides personalized daily reminders regarding scheduled rehabilitation activities. Cluster 4 - Monitoring (Autonomous Mode) The robot administers the Visual Analog Scale (VAS) for pain assessment and includes an exploratory function for detecting vocal distress keywords (e.g., "pain," "help," "thirst") using AI-based speech recognition, alerting staff when necessary. Primary endpoints include usability and feasibility (System Usability Scale - SUS; Questionnaire for User Interaction Satisfaction - QUIS; NASA Raw Task Load Index - NASA-RTLX; State-Trait Anxiety Inventory - STAI) and safety assessment through systematic recording of adverse events. Secondary outcomes include healthcare professionals' satisfaction with autonomous robot performance, patient satisfaction (Likert scales), and psychosocial impact on professionals (selected PIADS items). Additional exploratory assessments investigate subjective factors that may influence usability and feasibility. Before the first interaction, patients and professionals complete a short questionnaire on prior experience with robots, expectations, and initial perception of Alter-Ego. Perception measures (anthropomorphism, agency and experience, warmth and competence, perceived closeness) are repeated after each experiment. At the end of each experiment, participants take part in a semi-structured qualitative interview (15-30 minutes), audio/video recorded only with specific consent and analyzed through reflexive thematic analysis. The ALTER-EGO study aims to determine whether an anthropomorphic robotic platform can safely and effectively support multidisciplinary ALS care, improve workflow efficiency, and enhance patient-centered assistance in both hospital and transitional home-care settings.
