Per Odin, MD, PhD, Lund University, Lund, Sweden, discusses the tools available to monitor motor fluctuations. The Parkinson’s disease (PD) home diary has been frequently used in clinical trials to asset the effects of novel treatments on motor fluctuations. However, a recent study compared patient diary ratings of motor states to direct clinical assessments of an experienced observer, and the results found that the PD home diary only inadequately reflected actual motor states. The use of technology-based measurement tools, such as wearable devices, has the potential to provide more objective and clinically meaningful outcomes in PD patients with motor fluctuations. This interview took place at the 2022 International Congress of Parkinson’s Disease and Movement Disorders in Madrid, Spain.
