Physiotherapist performed Point of Care Ultrasonography (POCUS): a scoping review of 209 studies

Abstract

Background

Point of care ultrasonography (POCUS) is a non-ionizing imaging technique that is emerging in physiotherapy practice.

Objective

To systematically map the research literature on physiotherapist performed POCUS.

Data sources

Following PRISMA-ScR guidelines, OVID Medline, CINAHL, AMED, and EMBASE were searched.

Eligibility criteria

Peer-reviewed publications of physiotherapist performed POCUS were included.

Data extraction and data synthesis

Data collected included: title, author(s), journal, year of publication, design of included studies, sample size, age category of the sample, anatomical area of POCUS, geographical location of research, study setting, and disease condition/patient population. Data analysis consisted of descriptive statistics for the key characteristics of each research question.

Results

A total of 18 217 titles and abstracts and 1 372 full-text citations were screened, with 209 studies included. Most included studies were measurement studies that assessed the psychometric properties of POCUS in adult patients, were published in the United States of America and imaged the abdominal lumbo-pelvic region. Eighty-two percent of studies were published in the last 10 years.

Limitations

Non-English language, review articles and grey literature were excluded for feasibility. Studies were excluded if it was not clearly reported that a physiotherapist performed the POCUS.

Conclusion

This review identified a wide variety of practice settings and a diverse number of patient conditions in which physiotherapists are performing POCUS. This breadth and depth of this review highlighted the need for improved reporting of study methodology and key areas of future research in physiotherapy performed POCUS.

Contribution of the Paper

  • This is the first known scoping review of physiotherapist performed POCUS that included all areas of physiotherapy practice.
  • This review highlighted the wide variety of practice settings and diverse number of patient conditions in which physiotherapists are performing POCUS.
  • The most common study design were measurement studies, with most measurement studies investigating the reliability of physiotherapy performed POCUS of the musculoskeletal system or the abdominal lumbo-pelvic region, in healthy adult subjects.
