Temporal Associations between Sleep and Daytime Functioning in Parkinson’s Disease: A Smartphone-Based Ecological Momentary Assessment

Abstract: Objectives/Background: Disruptions to mood, cognition, and other daytime functioning are common and debilitating symptoms of Parkinson's disease (PD), and there is evidence that sleep problems contribute to these symptoms. However, previous studies are limited by reliance on self-reported sleep and cross-sectional designs. With the aim of assessing sleep as a possible treatment target for improving daytime functioning in PD, we used smartphone-based ecological momentary assessment (EMA) and actigraphy to inves… Show more

“…Among 17 studies, 6 studies collected symptoms using a smartphone accelerometer and gyroscope [ 16 , 20 , 21 , 24 , 25 , 28 ]. Further, 7 studies used wearable devices [ 20 , 23 , 26 , 27 , 31 , 33 , 35 ], which included a smartwatch [ 20 , 33 ], a smart insole [ 20 ], an actigraph such as a Fitbit [ 23 ], and sensors attached to the ankle [ 31 , 35 ], chest [ 26 ], or wrist [ 26 ]. Task performance was assessed in 9 studies [ 16 , 20 , 21 , 24 , 25 , 29 , 30 , 34 , 35 ].…”

“…Voice data were collected using the microphone of a smartphone in 2 studies [ 20 , 21 ], and 1 study collected voice data using a head-mounted condenser microphone [ 35 ]. Another method of collecting data on symptoms was a self-reported survey [ 20 , 22 , 24 , 26 , 27 , 30 , 34 ]. Structured survey tools for electronic patient-reported outcomes [ 22 ] and ecological momentary assessments (EMAs) [ 26 , 27 ] were developed.…”

“…Conversely, most authors used this tool to indirectly examine sleep quality through specific measures, such as the fragmentation index and sleep latency, time, and efficiency. Overall, studies that used actigraphy in PD addressed the following four main issues: (i) assessment of sleep features [ 13 , 16 , 17 , 20 , 21 , 22 , 23 , 24 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 ]; (ii) evaluation of therapeutic interventions [ 14 , 15 , 83 , 89 , 90 , 91 , 92 , 93 , 94 ]; (iii) validation of clinical scales [ 95 , 96 ], and; (iv) identification of specific primary sleep disorders [ 18 , 19 ].…”
