Biomechanical data is derived from the musculoskeletal system and the way it operates dynamically in relation to muscle force and the effects of gravity. Biomechanical analysis can be used to scientifically assess the causes of movement problems in individuals. This chapter discusses how, through the use of an innovative tool developed by the researchers to visualise older adult biomechanical data, evidence of understanding and experience of mobility issues during activities of daily living was gathered from older adults, healthcare professionals and design practitioners. It also discusses the potential role of this tool to facilitate cross-disciplinary discourse and deepen professional-practitioner understanding, and insights obtained about the experiences of older adults through empowering them, through the tool, to better engage in meaningful discussions with professionals.
