Like with many wearables in the marketplace, there is still a ways to go. There are issues around cost, communication optimization, and data quality, Kubota and Cohen said. But they also said that the Parkinson's study could someday lead to the development of better wearable monitors for patients with Parkinson's and other diseases. Certainly, though, this approach is a significant step up from more traditional Parkinson’s research assessments that involve outdated movement tests and questionnaires. Kubota, who said he still sees Grove weekly, is “optimistic that the data can be gathered by wearables to the point where we will be able to divide and conquer this disease.”
