What does traction aim to do with the spine?

Traction primarily aims to separate vertebral body surfaces, which is beneficial in relieving pressure on the intervertebral discs and nerve roots. By creating space between the vertebrae, traction can help alleviate pain, improve circulation, and promote healing in conditions such as herniated discs, spinal stenosis, and other musculoskeletal disorders. This separation reduces the stress placed on the spinal structures, which can lead to decreased pain and improved functional movement.

The other choices, while related to spinal health, do not directly describe the primary goal of traction. For instance, while traction may indirectly contribute to increased flexibility or decreased body tension, its main function is to create space within the spinal column. Strengthening spinal muscles, although important in overall rehabilitation, is not directly achieved through traction but rather through targeted exercises and physical therapy interventions.
