Conclusions
NLBP, disability, pain
The BSP-based intervention had beneficial effects on pain in patients with NLBP. In addition, this programme improved disability, physical components of quality of life and kinesiophobia in patients with NLBP. However, the psychosocial components of quality of life did not change after participating in the BSP. This programme could be easily implemented in hospitals, primary care centres and physiotherapy clinics with the aim of reducing the severe socio-economic impact caused by NLBP worldwide.
