The sophistication of yoga therapy research has progressed substantially. Researchers are beginning to identify outcomes that are uniquely associated with yoga therapy practices. Creditable research requires rigorous study design and careful attention to measurement and methodology. It is a process of excavation. As with other fields, much of yoga research started with general, surface-level questions: Does yoga help individuals who have arthritis, anxiety, or an eating disorder? Does yoga prevent the onset of these and other difficulties? Does yoga promote health? There is accumulating evidence that it may do each of these things and more.
