The Effects of Eight-Week Baduanjin Exercise on Chronic Low Back Pain and Disability Among Office Workers.

Inclusion Criteria: \- This study specifically targets office workers diagnosed with mechanical (or non-specific) chronic low back pain, which refers to persistent low back pain without a specific identifiable pathological cause such as disc herniation, spinal stenosis, or inflammatory diseases. Mechanical low back pain is the most common form of chronic low back pain among sedentary populations, particularly office workers, and is primarily attributed to musculoskeletal imbalances, poor posture, and prolonged sitting.Participants were included in the study if they met the following criteria: 1. Age and Occupational Requirements: Office workers between the ages of 20 and 55 years with at least two years of continuous employment. 2. History of Chronic Low Back Pain: Presence of persistent or recurrent low back pain localized below the costal margin and above the inferior gluteal folds, with a duration of more than three months. 3. Pain Intensity Assessment: A pain score exceeding 40 mm on a 100 mm Visual Analogue Scale (VAS), indicating a moderate level of pain. 4. Clinical Diagnosis Confirmation: Participants must be diagnosed with mechanical (non-specific) chronic low back pain by orthopaedic sports medicine specialists from the First Affiliated Hospital of Xi'an Jiaotong University. All participants will be required to submit their annual full-body medical examination report provided by the university between May 30 and July 30 each year. The Principal Investigator will collect these reports in advance and arrange for orthopaedic sports medicine specialists from the affiliated hospital to conduct an on-site screening at Xi'an Jiaotong University City College. During this process, specialists will review participants' medical history, evaluate physical symptoms, and consider available imaging reports (e.g., X-rays or MRI scans if previously conducted) to confirm the absence of specific spinal pathologies such as disc herniation or spinal stenosis. These specialists are experts in diagnosing and managing musculoskeletal conditions related to physical activity and sports, ensuring accurate assessment and classification of participants' chronic low back pain. Their involvement guarantees both clinical validity and safety in participant selection. 5. Cognitive and Physical Function: Normal cognitive function, adequate communication and interaction skills, and the physical ability to perform the basic movements of Baduanjin exercise. Participants must also hav…
