Background: Dizziness is one of the most common symptoms following concussion and requires a thorough vestibular assessment. However, due to limited tools and evidence on remote vestibular assessment and intervention, people unable to attend in-person consults cannot receive effective care. Objective: This study aims to describe the design and development process of MOVE-IT. MOVE-IT is a mobile phone application with an associated head mount device and clinician dashboard which aims to enhance vestibular assessments and intervention via telehealth by enabling clinicians to clearly observe client's eye movements. Methods: This study used a Living Labs methodology including the use of a scoping review, user engagement, multi stakeholder engagement, real-life settings, and co-creation. MOVE-IT was developed in three phases: Exploration, Experimentation and Evaluation. This paper describes the Exploration and Experimentation process. Exploration included a scoping review, focus group and consultation interviews. Experimentation included the co-creation of a minimum viable product in a real-life setting with regular feedback from multi-stakeholders. Outcome: MOVE-IT includes three components: a mobile phone application, head mount device and clinician dashboard. MOVE-IT aims to enhance the use of telehealth for vestibular assessments by: (1) using the head mount device to enable video recording of client's eyes during assessment, (2) allowing clinicians to view client's eye movements via the clinician dashboard whilst (3) a support person assists in the physical aspect of the vestibular assessment by a step-by-step guided video in the mobile application. Conclusion: The Living Lab method was a useful strategy for developing MOVE-IT. MOVE-IT meets all predefined functionality requirements and potentially provides a solution for remote vestibular assessment and intervention in the concussion population. The Evaluation phase will be conducted next to test usability, reliability and validity of MOVE-IT.
