Brief Summary

The goals of this observational study are: To determine the validity and reliability of the OPTIMAL-confidence scale in people with chronic low back pain. To assess the influence of confidence and fear of movement on the evolution of low back pain. The main question it aims to answer is if people with chronic low back pain present different psychoemotional variables around fear of movement and decreased confidence in their ability to perform movement that may influence their low back pain. For this purpose, a two-phase study was designed. In the first phase, the OPTIMAL-confidence scale will be validated in patients with chronic low back pain, determining its internal consistency and validity. In the second phase, a prospective study will be carried out with patients with low back pain who attend physiotherapy centres to determine how confidence and fear of movement influence the characteristics of pain and its evolution. Data will be collected at the beginning of the physiotherapy treatment, at the end of the treatment and after three months. The data will be analysed using learning machine techniques.

Secondary Outcomes (4)

  • Change from Baseline Kinesiophobia at 3 months.

    Recruitment, "physiotherapy discharge" (week 3) and 3 months later.

  • Change from Baseline Disability at 3 months.

    Recruitment, "physiotherapy discharge" (week 3) and 3 months later.

  • Change from Baseline Risk at 3 months.

    Recruitment, "physiotherapy discharge" (week 3) and 3 months later.

  • Change from Baseline Intensity of pain at 3 months.

    Recruitment, "physiotherapy discharge" (week 3) and 3 months later.

Other Outcomes (2)

  • Self-Efficacy.

    Recruitment.

  • Socio-demographic information.
