Repeat Xena linked pub. PDD trail and use of Actigraph may end up being significant value added device. If the device works as advertised in this trial (in addition to typical sleep measures) then it all fits well with the Precision Medicine initiative and our recent Consortium of WW leaders.
Sleep Fragmentation
Sleep fragmentation is probably the most common nocturnal complaint in Parkinson’s disease. Several studies analyzing sleep patterns in Parkinson’s Disease have found that the sleep pattern is more frequently interrupted and that the amount of time spent in slow-wave and REM sleep (the deepest and most restorative phases of sleep) is significantly less than that of age-matched adults without Pakinson’s. This type of sleep disturbance may be associated with a greater susceptibility to medication-induced hallucinations as well as excessive daytime sleepiness.

And, these kinds of trials are reproducible. Try that w/a survey.
