The Influence of the Timing of Postoperative Rehabilitation Intervention on the Clinical Efficacy of Unilateral Biportal Endoscopic Spine System in the Treatment of Lumbar Disc Herniation

"This intervention is a standardized, progressive rehabilitation protocol for patients after lumbar disc herniation surgery, delivered under the guidance of a senior physical therapist. The protocol aims to improve pain, restore function, and prevent complications through core stability exercises and neurodynamic techniques. The exercises are performed once daily and progressed based on patient tolerance. The protocol consists of two phases:~Initial Phase ( commencing postoperatively): Includes: 1) Transverse abdominis activation; 2) Sit-to-stand training with abdominal bracing; 3) Four-point kneeling rockbacks for spinal mobility; 4) Neural mobilization techniques (performed in sitting); 5) Neural sliding techniques (performed in sitting).~Progressive Phase: Builds upon the initial exercises by increasing the range of motion, adding isometric hold times, and integrating cervical movement with neural techniques to increase difficulty and intensity."
