回転性腱板障害患者に対する理学療法士による短期行動変容介入を統合したCOMBINEDアプローチの開発

Modifiable lifestyle factors (smoking, inactivity, overweight) could contribute to the onset and persistence of rotator cuff disorders, yet physiotherapy practice rarely addresses them. Brief interventions (BIs) can support behaviour change but are not routinely embedded in musculoskeletal care.

To develop The COMBINED approach: a physiotherapist-supported intervention integrating BI's targeting modifiable health behaviours into routine consultations for people with rotator cuff disorders; and to explore how physiotherapists can be supported to deliver it.

A theory-, evidence-, and pragmatic-based development process incorporated stakeholder co-design, behavioural theory, and evidence across three workstreams: (1) narrative review of BIs targeting smoking, inactivity, and weight management; (2) four co-design workshops with 26 stakeholders (physiotherapists, patients, experts) to select and adapt a BI and identify key intervention features; (3) theoretical modelling using COM-B, TDF, and BCTTv1 to map barriers/facilitators, select behaviour change techniques, and develop prototype components.

Fourteen BIs were identified; Moving Medicine had greatest utility. Barriers included time constraints, limited skills and confidence, and fear of offending patients, contrasting with patients' acceptability of lifestyle conversations. Recommendations included embedding the BI into routine care, scripts, infographics, patient resources, and training. Twelve TDF domains and 20 BCTs informed prototype development comprising: (1) patient-level intervention: a BI (adapted from Moving Medicine) embedded in routine consultations with tailored resources; (2) clinician-level implementation toolkit.

The COMBINED approach is the first formally developed intervention supporting integration of BI's within routine consultations for people with rotator cuff disorders and is now ready for feasibility testing.
