Abstract

Background
National surveys in New Zealand, Australia and the United Kingdom suggest ultrasound imaging (USI) use by physiotherapists is increasing. However, concerns exist regarding clarity for scopes of practice, and availability and standardisation of training.

Objectives
To investigate physiotherapists' understanding of scopes of practice for the use of USI; clarify the professional contexts, clinical uses and levels of training; and identify barriers preventing physiotherapists’ USI use.

Design
A cross-sectional, observational survey.

Methods
An Internet-based survey, offered in 20 different languages, was used including items covering five domains: (1) demographic and professional characteristics; (2) knowledge of scope of practice; (3) USI use; (4) USI training content and duration; and (5) perceived barriers to physiotherapists’ use of USI.

Results
1307 registered physiotherapists from 49 countries responded; 30% were unsure of the scope of practice for physiotherapists’ USI use. 38% of participants were users of USI, reporting varied contexts and clinical uses, reflected in the broader categories of: (i) biofeedback; (ii) diagnosis; (iii) assessment; (iv) injection guidance; (v) research; (vi) and teaching. The training users received varied, with formal training more comprehensive. 62% were non-users, the most common barrier was lack of training (76%).

Conclusion
These findings suggest physiotherapists' USI use is increasing in various contexts; however, there is uncertainty regarding scopes of practice. There are discrepancies in training offered, with a lack of training the most common barrier to physiotherapists’ use of USI. International guidelines, including a USI training framework, are needed to support the consistent and sustainable use of USI in physiotherapy.
