Validating clinical reasoning: a question of perspective, but whose perspective?

This paper explores the notion of validity from different perspectives and addresses its integration with clinical reasoning. Whilst valuing the evidence-based practice (EBP) perspective in our quest for validation of practice, the authors posit that other perspectives may provide added value through their potential for offering validity in differing circumstances. The reality of the EBP aspiration is discussed and nuances within the evolved term 'research-enhanced practice' are shared. Validity theory applied through different perspectives may, it is argued help to get to grips with the balancing act of validating manual therapy practice.
