Intersegmental Spinal Traction (IST)

The primary indications for intersegmental spinal traction are degenerative disc disease, joint hypomobility, and muscle spasm. Basically, traction encourages length, alignment, and functional stability. These goals become a priority in cases of mild structural compression that result in ischemia and pain sited either locally and/or distally, resulting in muscle spasm producing functional contraction. The associated nerve irritation, which may be sensory, motor, or both, may exhibit signs of pain, flaccidity, and diminished reflexes.
