Description

Technical Field

[0002] Lumbar disc herniation is a common and frequently occurring disease in clinic. Traction is a safe treatment for lumbar disc herniation with few serious complications. With the development of modern medicine, the in-depth understanding of the pathological mechanisms of spinal and musculoskeletal diseases and the advancement of traction bed-related technologies have laid a theoretical foundation for the development and clinical application of modern traction technology.

[0003] Traction therapy achieves its therapeutic purpose by applying mechanical force to stretch the spine and related soft tissues, thereby reducing nerve compression and restoring the morphology of the intervertebral disc.
