The Intervention Effect of Exercise on Lumbar Multifidus Muscle Injuries

This is a single-center, prospective interventional study. The main purpose is to use ultrasound radiomics to analyze changes in multifidus muscle ultrasound imaging features before and after rehabilitation therapy in patients with low back pain related to lumbar multifidus injury, and explore whether these imaging features can be used to evaluate treatment response. Eligible participants are aged 18-80 years with chronic non-specific low back pain lasting more than 3 months, NRS/VAS pain score ≥1, and abnormal baseline ultrasound findings of the lumbar multifidus muscle. All participants will receive a 12-week home-based rehabilitation program, including prone multifidus activation exercises and core stability training, 3-5 times per week, 20-30 minutes each session. The primary outcome measures are changes in multifidus muscle area, ultrasound imaging features and pain scores after training. Safety will be monitored throughout the study. Training will be adjusted or paused if participants have increased pain, new radiating leg symptoms, dizziness, chest tightness, palpitations, or other adverse conditions.
