Effect of an Intervention Based on Back School in an Aquatic Environment on Non-specific Low Back Pain

Participants will undertake a back school-based program. This program will follow the recommendations of the biopsychosocial model of chronic pain and will be conducted in an aquatic environment. The intervention will be carried out by physiotherapists in a sports center. The duration of the intervention will be six weeks, with a frequency of two sessions per week, totaling 12 sessions of 45 minutes each. Of all the sessions, 10 will have a practical focus (centered on trunk exercises) and the other two will have a theoretical focus (providing education on pain and risk factors for low back pain).
