Abstract
Videofluoroscopic swallow studies (VFSS) are often considered the ‘gold standard’ technique to assess dysphagia. Despite this status, unanimous agreement has not been reached regarding the protocol for this procedure. Review of the literature reveals two main schools of thought. The first advocates a uniform, standardised protocol used with all patients. The second argues for functional, tailor-made studies, which aim to elicit a sample of swallowing representative of typical feeding patterns. This paper reviews the literature on VFSS methodology and evaluates the applicability of protocols to the paediatric population. Broadly speaking, adult protocols tend towards uniform procedures, whereas paediatric studies aim to be more individualised and tailor-made. Clinical recommendations based upon VFSS are examined in the light of validity and reliability issues. The need for standardisation of the VFSS procedure is highlighted. The question is raised whether it is possible to achieve uniformity and consistency between clinicians and still perform patient-centered, tailor-made VFSSs, which are truly representative of a patient’s swallow function. It is revealed that dysphagia specialists should achieve greater consistency in the VFSS procedure before claiming to be implementing a ‘gold standard’ technique.
