Advocating for PD awareness, education, and increased clinical trial participation in this day and age is as powerful as it has ever been.
The use of social media makes our work powerful when an advocate can recommend certain research sites that have shown their willingness to treat volunteers with respect, making sure that their needs are met (including trial-related expense reimbursement) throughout their time involved in the trial, and made to feel that their commitment to the PD cause is appreciated.
"Word of mouth" these days has been changed to "Re-tweet" on Twitter and "Like" on Facebook. Imagine if you will the exponential power of the PD community letting their followers or friends know of the positive experiences they have had at certain sites and willing to recommend these to fellow PwP's.
Let us use the power of advocacy, which is a mighty one indeed, to send out those tweets, status updates, blogs, and any other means available to us to push research forward by letting POSITIVE-OUTCOME research sites known by name so that many more volunteers are willing to walk through their doors. I would venture to say that research organizations wouldn't mind being mentioned in a positive way for the work that they do.
