Remote smartphone monitoring of Parkinson’s disease and individual response to therapy

Abstract: Remote health assessments that gather real-world data (RWD) outside of clinic settings require a clear understanding of appropriate methods for data collection, quality assessment, analysis and interpretation. Here, we examine the performance and limitations of smartphones in collecting RWD in the remote mPower observational study of Parkinson's Disease (PD). Within the first six months of study commencement, 960 participants had enrolled and performed at least 5 self-administered active PD symptom assessments… Show more

“…In this study, we customized a smartphone research application (mPower) that has been previously used in an observational study of over 15,000 participants [13, 16]. The smartphone application had a set of 7 active tasks (finger tapping, standing still for 30 s, walking for 30 s, saying “aaah” for 10 s, assessments of rest and postural tremor, and a brief spatial memory test) designed to assess domains affected by Parkinson’s disease.…”

“…One of the shortcomings of current biomarker studies of mTBI is reporting values at a single, and varying, post-injury time-point [ 61 ]. The availability of digital devices provides an opportunity to explore and adopt digital biomarkers as objective quantifiable measures [ 69 , 70 ]. Although an experimental study of intentional falls from a wheelchair among able-bodied young adults using Apple Watch showed poor sensitivity for fall detection [ 71 ], numerous anecdotes of improved outcomes from hard falls due to detection by Apple Watch consistently make the news.…”

“…In fact, alternating finger tapping has been shown to be the most effective motor predictor for conversion from idiopathic REM sleep behavior disorder to Parkinson's disease, with deficits observed nine years prior to conversion 13 . The effectiveness of differentiating PD from controls has led to the widespread implementation of finger tapping on smart phone battery of assessments for PD 12,[14][15][16][17] . However, smartphone applications are limited to temporal metrics of tapping and position in 2D space of the fingers 15 .…”
