Capturing nighttime symptoms in Parkinson disease: Technical development and experimental verification of inertial sensors for nocturnal hypokinesia

Roongroj Bhidayasiri, MD, FRCP, FRCPI, et al.

Nocturnal disabilities are very common among patients with Parkinson disease (PD), with up to 96.6 percent of patients reporting at least one nocturnal symptom. These symptoms negatively affect patients??? quality of life and increase caregiver burden. As one of the nighttime disturbances in PD, nocturnal hypokinesia contributes to nighttime falls. The majority of falls happened in bedrooms when patients attempt to get out of bed. The aim of our study was to develop a portable ambulatory motion recorder (the NIGHT-Recorder) that can quantify nocturnal hypokinesia in patients with PD. As part of the experimental verification, the device was able to capture the problems of fewer and slower rolling over episodes in patients with PD compared with their spouses. In contrast, PD patients got out of bed more often than their spouses. Therefore, the device helps identify those patients at risk for nighttime disabilities for early intervention that includes rehabilitation. Our study shows that it is technically feasible to develop a portable device to assist physicians in identifying patients who suffer or are at risk of nocturnal hypokinesia. Additional studies are warranted to develop protocols for early treatment and rehabilitation, as well as strategies to prevent nighttime falls or accidents in PD patients.
