The human spine is a complex anatomical structure with 33 interlocking bones called vertebrae that hold the spinal cord, and between each vertebra sits a disk that acts as a cushion between the bones. This structure allows us to bend, reach, walk, dance and actively live our lives.

When back pain starts, from a muscle pull or sitting too long in front of a computer, it becomes clear how much we depend on our backs to move freely.

“It’s best to take an active role in caring for your back and strengthening the core muscles that support your back,” says Nick Shamie, M.D., a professor of orthopaedic surgery and neurosurgery at UCLA School of Medicine and professor and chief of spine surgery in the Department of Orthopaedic Surgery at the David Geffen School of Medicine at UCLA.

A simple piece of equipment called a back stretcher can help, especially when incorporated into a yoga, stretching or exercise routine. And when we do experience mild back pain, a back stretcher may provide welcome, if temporary, relief.
