RESUMO
BACKGROUND: The effectiveness of physiotherapist-led Cognitive Behavioural Interventions (CBI) with or without physiotherapy is still unclear. OBJECTIVE: This systematic review (PROSPERO registration number CRD42022321073) aims to determine the effectiveness of physiotherapist-led CBI with or without physiotherapy in comparison to physiotherapy alone on quality of life, disabilities and catastrophization. METHODS: MEDLINE, Web of Science, Science Direct, and PEDro were searched for randomized controlled trials that investigate the use of CBI versus conventional physiotherapy in chronic NSLBP. To be included CBI had to be performed by a physiotherapist. The primary and secondary outcomes were respectively quality of life and disability. RESULTS: Fourteen studies were included in qualitative analysis, in which 4 did not meet the PEDro score of 6 or higher. Pooled standardized mean differences from 3 studies showed no difference in quality of life between groups for mental and physical sub-scores at 3 months (SMD 0.02, 95% CI -0.17 to 0.21 and SMD 0.07, 95% CI -0.12 to 0.26 respectively). Pooled standardized mean differences from 9 studies showed no difference in disability between groups at 3, 6 and 12 months (SMD = - 0.40, CI 95% -0.80 to 0.01; SMD -0.18, CI 95% = -0.41 to 0.05; and SMD -0.24, CI 95% = -0.48 to 0.00 respectively). CONCLUSION: Results of CBI, especially cognitive functional therapy, seem promising in disability management despite a substantial heterogeneity. Furthermore, we found no difference in quality of life.
