Telerehabilitation Program to Improve Function in People With Chronic Low Back Pain Compared With Conventional Care

The goal of this clinical trial is to evaluate whether an additional telerehabilitation program, combined with conventional care, can improve functional recovery in adults with chronic low back pain treated in primary care clinics of the Mexican Institute of Social Security (IMSS). The main questions it aims to answer are: * Does the telerehabilitation program lead to greater functional improvement, measured by the Oswestry Disability Index (ODI), compared with conventional care alone? * Does the program reduce pain intensity and improve adherence and satisfaction among participants? Researchers will compare patients receiving conventional care plus telerehabilitation with those receiving conventional care only to determine whether the digital intervention provides additional clinical benefits. Participants will: * Continue their usual medical care for chronic low back pain at IMSS clinics. * Follow a 6-week telerehabilitation program delivered through an online platform, including educational videos, stretching and strengthening exercises, and weekly virtual check-ins. * Complete baseline and post-intervention assessments of pain, disability, and satisfaction.
