Abstract
The article focuses on topics, approaches, and methodological perspectives of qualitative intervention research developing within an experimental science-oriented research environment. Recent stroke rehabilitation studies from physical, occupational and speechlanguage therapy and nursing sciences predominantly utilize qualitative content summary, largely without reference to established qualitative research approaches. A majority of these studies is characterized by inventories of topics covered by research participants in interviews and focus groups. Based on existing typologies of qualitative findings, opportunities for developing the complexity and explanatory power of qualitative intervention research are discussed. A more thorough methodological foundation and quality control are important tasks for future development.
