What is it about?

This viewpoint article reviews the history of evidence-based medicine and argues that synthesizing evidence gathered from a wide variety of research designs, methods, and perspectives is more important than applying a strict evidence hierarchy. Concepts from a wide variety of fields including philosophy of science, research design and methodology, and precision medicine are brought together in an attempt to focus research on the scientific understanding of aphasia treatment effects.

Why is it important?

It is hoped that by incorporating diverse research designs, methods, and perspectives, researchers and clinicians will become better able to provide effective, personalized treatments for people living with aphasia to ensure that each person is able to improve their communication ability and quality of life.

Perspectives

This article builds on some of my ideas about scientific approaches and evidence that I have shared in earlier articles. I hope that this article will reach students and early career researchers. I believe that synthesizing high caliber research, using different approaches and perspectives, will ultimately improve the lives of people living with aphasia.
