Parkinson's disease - Streamlined clinical trials, from a home computer

A Parkinson's research and treatment center is experimenting with an unusual new approach to clinical trials- have participants assess themselves from their home computers potentially using everything from videos of tremors to a mouse that senses motor abilities. If it works, the strategy could greatly reduce the need for doctors' visits and make trial participation vastly cheaper and possible from anywhere in the world. The organization will design questionnaires for participants to accurately capture their health and health history. Volunteers submit saliva samples that will be sequenced for single-base variations. One concern, is that relying on volunteers to run through such tests out of sight of clinicians may lead to bias.
