Purpose: To investigate the expectations regarding physiotherapists of patients attending an interdisciplinary CLBP rehabilitation programme and the response to these expectations. Materials and methods: A thematic analysis was conducted, based on interviews of working-age patients with CLBP and without significant comorbidities. Results: Twenty patients participated (9 male, 11 female, aged 21–58 years; symptoms duration 4.3 ± 3.0 years; pain VAS 53 ± 21 mm). Patients expected to learn pain and activity management. Expected outcomes were a reduction of pain, increased well-being and a return to normality. A collaborative approach involving therapeutic and relational adaptation was expected. Despite divergences concerning emotional aspects, patients expected a large range of applied psychosocial skills. The programme met the expectations of most patients, especially when its goals matched those reported by the individuals. For most participants, the pain relief was below expectations. Active therapies were valued. After the programme, patients felt more ready to take responsibility for their back. Conclusion: The expectation of developing self-management skills was prevalent. Expected treatments were mostly compatible with recommendations. Expectations to resume activities and decrease pain were in line with the rehabilitation goals, although the expected reduction in pain was overestimated. Relational expectations converged towards patient-centred care.
