“…Stable scanner placement, known to be critical for quality of ultrasound recordings [ 12 ], may have been compromised as the researcher kept an arm-length distance from the participant for radiation safety [ 21 ]. For future studies, advantages of the use of a stabilisation unit for scanner placement during videofluoroscopic imaging would need to be balanced against the issues related to the use of these devices, such as the risk of loss of contact between the scanner and the skin [ 22 ].…”

“…While there are some data to suggest that standard-sized US equipment may provide reliable and valid swallowing measures [ 5 , 12 , 16 ], this could not be confirmed for pocket-sized technology [ 24 , 60 ]. The method of data acquisition, such as the use of hand-held versus fixed transducers, may further affect reliability [ 61 , 62 ]; as might variability between different data collection settings, for example, data collected in the clinical versus research environment. The relationships between reliability, validity and the assessment protocol are reciprocal.…”

Translating Ultrasound into Clinical Practice for the Assessment of Swallowing and Laryngeal Function: A Speech and Language Pathology-Led Consensus Study

Ultrasound (US) has an emerging evidence base for the assessment of swallowing and laryngeal function. Accessibility and technological advances support the use of US as a clinical assessment tool; however, there is insufficient evidence to support its translation into clinical practice. This study aimed to establish consensus on the priorities for translation of US into clinical practice for the assessment of swallowing and laryngeal function. Nominal Group Technique (NGT) was used as a formal method of consensus development. Clinicians and academics, all members of an international US working group, were invited to participate in the study. Two NGT meetings were held, where participants silently generated and then shared ideas. Participants anonymously ranked items. Rankings were aggregated before participants re-ranked items in order of priority. Discussions regarding rankings were recorded and transcribed to inform analysis. Member-checking with participants informed the final analysis. Participants (n = 15) were speech and language pathologists, physiotherapists and sonographers representing six countries. Fifteen items were identified and prioritised 1–13 (including two equally ranked items). Reliability, validity and normative data emerged as key areas for research while development of training protocols and engagement with stakeholders were considered vital to progressing US into practice. Analysis revealed common themes that might be addressed together in research, in addition to the ranked priority. A measured approach to the translation of US into clinical practice will enable effective implementation of this tool. Priorities may evolve as clinical and professional contexts shift, but this study provides a framework to advance research and clinical practice in this field.

“…Manual rather than fixed scanner placement was selected to improve clinical applicability. Further, there are inadequate data to suggest greater measurement precision by utilisation of scanner stabilization (Perry et al., 2016 ). Two‐dimensional grey‐scale imaging was performed using brightness mode and preset scanning depth and gain.…”

Background The use of ultrasound as an adjunct to clinical swallowing evaluation provides quantitative physiological and morphological data. As a low‐risk procedure, ultrasound imaging can be performed outside of a medical setting. This is particularly important for patients living in rural areas with restricted access to a hospital. Technical advances have produced pocket‐sized ultrasound technology that is more affordable, and therefore within the fiscal reach of most allied health services. Aims To explore the validity and reliability of pocket‐sized ultrasound technology in dysphagia assessment. Methods & Procedures Data were acquired from 43 patients with dysphagia using the Clarius ultrasound device. Ultrasound and videofluoroscopic measures of hyoid and laryngeal displacement during liquid and puree swallowing were collected concurrently to quantify correlation and agreement between identical measures derived from the two instruments. Reliability of ultrasound was assessed for measures of hyoid and laryngeal displacement, tongue thickness, and size of the submental muscles in eight patients. Reliability was evaluated for the entire process of data acquisition including scanning and online measurement using an iPad in a clinical setting and for offline measurement on a computer screen to explore environmental influences on reliability. Outcomes & Results Results revealed poor correlation between the measures of interest across instruments. Reliability of the entire process of data acquisition in a clinical setting was insufficient while reliability was more promising for offline measurements. Conclusions & Implications The clinical use of pocket‐sized ultrasound devices, such as the Clarius system, for swallowing evaluation is not indicated at this time. Enhanced validity and reliability of the entire process of data acquisition are needed prior to clinical translation of such technology. WHAT THIS PAPER ADDS What is already known on the subject The use of ultrasound allows for radiation‐free, non‐invasive swallowing assessment. Some data suggest that ultrasound is valid and reliable in the evaluation of swallowing using standard‐sized equipment. Insufficient validity and reliability have been reported for pocket‐sized ultrasound technology in the assessment of healthy swallowing. What this paper adds to existing knowledge This research is the first to provide validity and reliability data of the pocket‐sized Clarius technology in the evaluation of swallowing in patients with dysphagia. Insufficient validity and reliability of online data acquisition in a clinical environment were found. Reliability for offline measurement was more promising. What are the potential or actual clinical implications of this work? The clinical use of pocket‐sized ultrasound devices, such as the Clarius system, for swallowing assessment is not indicated at this time.
