Over the last decade, a growing number of researchers have used advanced wireless technologies including wearable sensors for objective evaluation of specific motor symptoms in patients with Parkinson's disease (PD). In the near future, sensing technologies will likely provide relevant advances in the clinical management of patients with PD, contributing to early diagnosis, disease progression monitoring and therapeutic approach. In this regard, this eBook hosts new original studies focused on the objective monitoring of motor symptoms and therapeutic perspectives of wireless technologies in patients with PD.
