Technologies in Mobility Disorders

Mobility is defined as the ability to independently move around in the environment; it is a strong prognostic marker for disability and mortality in the general population, and it is a key contributor to quality of life, especially in older age. The digital assessment of mobility has been recently recognized as pivotal endpoint for pharmacological and non-pharmacological interventions [1]. The normal aging process has been associated with several changes in mobility, including the global speed and ability to move but also specific modifications of gait and balance, two of the most basic movements of the human body [2]. Therefore, technology can already be considered as important for measuring mobility and its limitations, e.g., due to ageassociated diseases. This chapter will delineate why and how digital health echnology for diagnosis as well as determination of progression and treatment response in chronic age-related diseases will become an inevitable part of clinical management in the course of the next years.
