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.
