What is a common purpose of using traction in physical therapy?

Using traction in physical therapy serves the common purpose of relieving pressure on spinal nerves. This technique involves applying pulling forces to the spine, which helps to decompress spinal structures such as intervertebral discs and surrounding soft tissues. When traction is applied, it creates space between the vertebrae, which can alleviate nerve compression, reduce pain, and improve mobility.

This therapeutic approach is particularly beneficial for patients suffering from conditions like herniated discs, spinal stenosis, or radiculopathy, where nerve roots may be compressed due to the alignment of the vertebrae or disc issues. By relieving this pressure, traction can facilitate healing, enhance blood flow to the affected areas, and promote an overall improvement in function and quality of life.

The other options do not align with the primary purpose and application of traction. Enhancing muscle mass, improving joint stability, and enhancing respiratory function are objectives that can be achieved through various other therapeutic modalities but are not typically addressed through spinal traction.
