Open research questions in Dysphagia Assessment and Management

51 unresolved questions extracted from the limitations and future-work sections of 631 Dysphagia Assessment and Management papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • A more comprehensive safety pro- file remains to be established. The first limitation of this study is its non-randomized design, which was a methodological necessity to evaluate the scale’s clinical utility. Future randomized controlled studies are warranted to validate the superiority of IOE over NGT, independent of the selec- tion criteria. Future randomized controlled trials with larger samples and pre-planned adjusted analy- ses are warranted.

  • Purpose Evaluation and treatment of pediatric dysphagia, swallowing difficulties occurring during childhood, is in the speech-language pathologists' (SLPs) scope of practice; however, little is known regarding the education SLPs receive during their graduate work and afterwards to effectively assess, treat, and manage this diagnosis.

  • 6 Few studies have reported the prevalence of dysphagia in the independently living elderly population,7-9 and these studies have used a variety of nonvalidated instruments based on self-reported dysphagic symptoms, thus not reporting the real prevalence of dysphagia because the sensitivity and specificity of the tests were not taken into account.

  • It is recommended that this study should be replicated with a control group and a larger sample using either FEES or video fluoroscopy for scientific data to further substantiate music therapy outcomes in stroke rehabilitation.

  • BACKGROUND: A lack of data on dysarthria and dysphagia outcomes for children following traumatic brain injury (TBI) limits our clinical evidence base, and poses daily challenges for the speech language pathologist (SLP) managing this group.

  • summary This review emphasizes the following points: 1 The values of the physiological parameters of mastication (number of cycles and total electromyographic activity in the sequence, sequence duration, cycle frequency in the sequence, kinetic characteristics of the cycles) are characteristic of each individual and vary widely from one individual to another.

  • Applying pulse oximetry simultaneously to SSA can possibly add to the accuracy of aspiration detection, especially silent aspiration (limited evidence).

  • Future studies are needed to provide elaborate and comparable evaluation protocols and reporting of FEES in individuals with TBI.
