A traction machine typically refers to a device used in medical settings, particularly in physical therapy or rehabilitation. It's designed to apply a pulling force to a specific part of the body, often the spine or limbs, in order to relieve pressure, stretch muscles or ligaments, or correct alignment issues.

There are various types of traction machines, ranging from simple manual devices operated by a therapist to sophisticated motorized systems that can apply precise amounts of force. In spinal traction, for example, the machine gently stretches the spine to alleviate pressure on discs and nerves, providing relief for conditions like herniated discs or spinal stenosis.

The traction machine is often used as part of a broader treatment plan prescribed by a healthcare professional. It's important for the machine to be used under supervision to ensure proper technique and safety.
