Research   
A Speech-Language Pathologist tracks speech volume and quality on a computer monitor

Diagram: Evidence-Based Practice=Patient Satisfaction + Expoerts + EvidenceEvidence-Based Practice (EBP) occurs when the following three components intersect: evidence that a treatment works; an expert who provides the treatment; patients who enjoy and profit from the treatment. After all, what good would a therapy program be that was effectively administered by an expert if the patients thought it was boring?

Parkinson Voice Project provides extensive training to our clinical staff (experts); our therapy programs are effective, fun, and interesting (patient satisfaction); and now, we are grateful to have independent researchers in the speech-language pathology community proving the efficacy of SPEAK OUT!® and The LOUD Crowd® (evidence).
