Participant selection and recruitment
We recruited practicing physical therapists with no restrictions on age, sex, clinical experience, area of speciality, or country of practice. The APA included a study invitation in two of their monthly newsletters and the Sydney Local Health District sent out study invitations via email to physical therapists working at Concord Hospital and Royal Prince Alfred Hospital. We also posted the study invitation on Facebook and Twitter. The invitation briefly outlined the purpose of the study and included a hyperlink that directed potentially interested physical therapists to complete the survey. Consent was obtained from all participants who completed the survey. Ethics approval was granted by Review Committee (Royal Prince Alfred Hospital Zone) of the Sydney Local Health District (protocol number: X19–0175 & 2019/ETH1151).
