Mechanical traction is a therapeutic technique used by physical therapists to alleviate neck and back pain by gently stretching the spine and decompressing the intervertebral discs. This method involves the use of a traction machine or manual devices that apply controlled force to elongate the spine, which can help relieve pressure on nerves, reduce muscle spasms, and improve overall spinal alignment. 

Patients often experience increased mobility and decreased pain following treatment, making it particularly effective for conditions such as herniated discs, sciatica, and chronic back pain. By promoting relaxation and enhancing circulation, mechanical traction can support a more effective rehabilitation process and improve quality of life.
