Recruitment strategies and reason for success

Recruitment strategy	Reason for success
Fast-track scheduling	Shortened time for entry into the clinic and subsequently to recruitment
Research meeting recruitment reviews	Reminder to clinicians of the study entry criteria every Monday morning before the week’s clinics, increasing real-time recruitment
Clinical repository enrollment	Allowed creation of reminder sheets for recruitment into the exercise study at the time of the patient’s clinic visit
Contiguous clinic and research space	Study coordinators could meet with the potential subject immediately at the time of the clinic visit
Wait-listed control group	All patients knew that they would be receiving an exercise intervention
Local exercise and paid gym memberships	Patients could exercise locally and reduce the need to drive into a high traffic urban center
Heart rate monitors could be mailed back to study team	Alleviated the need for patients to travel back to the research clinic to return equipment
Multiple neurologists on the study	Allowed for in-person recruitment and more options for research visit scheduling at all times by a study neurologist
Experienced RN study coordinator	Facilitated recruitment by multiple techniques: support groups, social media, and after hours
Focused minority recruitment training	Raised investigator awareness and resulted in increased numbers of minorities recruited
De novo PD population	May be more motivated to participate in an intensive one-year exercise study due to a milder phenotype
Outreach to local neurologists	Increased the numbers of patients referred from the community for recruitment
Parkinson disease 101 course started	Focus on de novo Parkinson disease allowed for targeted recruitment at the quarterly seminars
