Acceptability and feasibility of implementation of the WalkBack intervention into clinical practice: A mixed-methods study.

Low back pain (LBP) is the leading global cause of disability. Its recurrent nature is a major cause of the burden, with ~70% of individuals experiencing a recurrence of LBP within 12 months following recovery, and half of these seeking care. Our recently completed NHMRC-funded WalkBack trial (n=701) found that a physiotherapist-facilitated walking and education intervention was effective for preventing LBP recurrences and associated care seeking (accepted at LANCET). These exciting results provide an opportunity to markedly improve physiotherapy management of recurrent LBP. Since the intervention was tested in a controlled research environment and participants were predominantly recruited from the community, it is yet to be determined how this intervention can be implemented in real-world clinical settings. This study will invite physiotherapists to implement the WalkBack intervention in their clinical setting. This study aims to assess the feasibility and acceptability of implementing WalkBack in routine practice. Specifically, we aim to: 1.Determine the number of patients with LBP offered WalkBack, the proportion who agree to participate, and the characteristics of these patients. 2.Describe how clinicians adapt WalkBack for delivery in their clinical setting (e.g., number of sessions, prices charged). 3.Identify the barriers and enablers to the implementation of WalkBack.
