Back stretches when done on a regular basis will maintain the flexibility of your spinal ligaments, muscles, and fascia. Maintaining back mobility by doing a few back stretching exercises on a regular basis is important in terms of preventing back pain. If you are looking to relieve back pain or dysfunction or even back pain that has come on "for no particular reason" that may or may not have resulted from a back injury, it is best to consult a physical therapist rather than try all the back stretches out there. Your particular problem may require specific stretches in a particular direction. Working or stretching in the wrong direction could make your problem worse. Your physical therapist can diagnose mechanical problems and prescribe the correct back exercises for you.

Anatomy of the back
Why do we do back stretches?
The purpose of doing back stretches is multifacetted. Back stretches are necessary to maintain mobility, maintain joint health, sustain a good posture, and normalize forces on discs.
Maintain Mobility
Like all joints if you fail to take the joints in your back through their full range of motion on a regular basis you will eventually lose that range of motion. Like the saying "if you don't use it, you lose it." You can observe this in someone that has to spend weeks in a cast due to a fracture. While the fracture heals usually without issue, the joints that have been immobilized have become stiff because soft tissues have shortened, muscles have become weak, and cartilage has become softer. If we maintain our joints in a range that allows the surrounding soft tissues to shorten then eventually they will shorten and lead to stiffening.
Maintain Joint Health
The cartilage in the joints of your spine do not have a blood supply. They instead derive nutrients like a sponge through diffusion. It is the movement and compression of the cartilaginous surfaces that maintains their optimum health. back stretches will take your joints through their full range of movement.
Sustain a Good Posture
If you cannot move your joints into a position of good posture you simply cannot maintain a good posture. When we are children we have good movement between each segment of the spine, so when we twist our back or turn our head we do so by moving many joints. As we get older and some joints lose mobility, others have to compensate by becoming hypermobile or too mobile. This can lead to premature joint degeneration. If we can maintain mobility in all segments by doing back stretches we can minimize stress on those that would need to compensate for that loss.
Normalize Forces on Discs
I like to compare discs to jelly donuts in order to explain the hydrostatics to my patients. When you compress one side of a jelly donut, the jelly gets pushed to the other side. As it pushes it strains the annular fibres that hold it in. Over time and with age and previous injuries these annular fibres break down, develop cracks and fissures and can allow the jelly material to bulge. By doing back stretches in certain directions we can alter the position of the jelly material and minimize the stress on those annular fibres.
What happens if we never stretch our back?
Gravity is an ever present and dangerous force we live with on a daily basis. Unless we fight it, gravity will always win. That normal "S" shaped curve we all should have becomes shorter and more compressed if we let it. It is usually at the peaks of those curves in the "S" that we develop pain, strain, arthritis, compression fractures, etc. If we slouch and let gravity take hold we are essentially hanging on our ligaments and joints as opposed to keeping our joints in a nice neutral position. This will lead to regions of hypo mobility (stiffness) and hypermobility(too much movement) and subsequent degenerative changes.
Can back stretches correct back pain?
This of course depends on what is causing your back pain. Sources of back pain can be
Obviously not all of these problems will respond to simply stretching the back. Consult your family physician or physical therapist if the source of your back pain has never been diagnosed. It is important to rule out serious problems rather than dismissing them in hopes of self treating.
Pain originating from ligament strains, muscular fatigue, and bulging discs will respond to the correct forms of stretching. That type, frequency and direction of stretching should be prescribed by a physical therapist. The wrong type of stretching in these cases could potentially make your pain and your condition worse.
Can stretching your back prevent back pain?
Stretching your back will prevent mechanical back pain that results from shortening soft tissues. We call this a dysfunction. A dysfunction results when a spinal segment or segments lose their range of motion. This is usually a progressive condition that develops slowly over the course of years through the maintenance of poor postures. (not to be confused with Scheuermann's disease, or spondyloarthropathies).
By stretching your back on a regular basis you stretch the ligaments as well as the muscles and prevent the shortening that leads to dysfunction. Also,by avoiding slouched or forward head postures we don't allow excessive stretching forces to deform the supporting connective tissues leading to hypermobility which can lead to disc degeneration and arthritis.
How do I know what stretches to do for my back?
Which back stretches you need to do for your back will depend on many factors:
As it is impossible to present every scenario, I advise that you consult your physical therapist if you have any concerns or underlying conditions.
Here are some back stretching exercises suitable for a generally healthy population to maintain mobility. If you have pain or an underlying or preexisting condition consult your physical therapist to see if these back stretches are appropriate for you.
Flexion in Lying
You should pull only to the point of tension. You should not pull into any pain, bounce, or force the movement. If you are stiff in this direction it may take you months of repeating this exercise to regain full range of motion. This exercise is best not done in isolation. Most people should follow this exercise by Repeated Extension in Lying.
Repeated Extension in Lying
You should push only to the point of tension while maintaining your hips on the floor. You should not push into any pain, bounce, or force the movement. You should have a gentle curve in your back as you push up, no severe curvatures in one location. If you are stiff in this direction it may take you months of repeating this exercise to regain full range of motion. Stretching the ligaments of the spine safely is like moving teeth. It takes a small force on a repetitive basis over a long period of time. If you hold this stretch it can lead to excessive forces exerted on just a few joints as opposed to having the forces distributed along the whole back. Be gentle. It's likely that your back has become stiff over years, and that's not going to be fixed in a few weeks. It can take months.
Supported Upper Thoracic Extension
You should push only to the point of tension. You should not push into any pain, bounce, or force the movement. If you are stiff in this direction it may take you months of repeating this exercise to regain full range of motion. This exercise stretches the ligaments on the front in your spine as well as taking pressure off the discs and vertebral bodies. It is good to do this stretch if you are in an occupation that involves periods of prolonged sitting
Doorway Stretch
Your step should be small enoughso that you feel a pulling in your chest, but no pain. This is a particularly good stretch if you sit at a desk all day. In that position the pectoral muscles get tight and pull your head forward. Head forward postures can be the cause of headaches, disc injuries, and dysfunctions. If you have any history of shoulder injuries or instabilities, consult your physical therapist prior to trying this exercise.
Back over a Pillow
This back stretch helps to reverse the kyphosis in the thoracic spine. While it is normal to have a kyposis, gravity is always working to exaggerate it. Excessive kyphosis puts pressure on discs and vertebral bodies, and in severe cases can interfere with breathing.
Pelvic Tilt
If you do not feel your lower back pressing against the floor you may be tight in that region. Place your hand under your lower back. Doing the pelvic tilt you should feel your lower back pushing down on your hand. Do not hold your breath.
The pelvic tilt is a dynamic way of stretching the lumbar extensors. The easiest way of performing the pelvic tilt is lying down. As this is mastered you should try it standing with your back against the wall or when on all fours.
Kneeling Lumbar Flexion
This is a gentle stretch for the lumbar extensors. Also being stretched are latissimus dorsi, teres major, lower trapezius, gluteals, lumbodorsal fascia, part of the quadriceps, and ankle dorsiflexors.
The spine is the supporting structure that makes up the axial skeleton. There are 33 vertebrae in most people: Seven cervical vertebra, 12 thoracic vertebrae, five lumbar vertebrae, a sacrum consisting of five fused vertebrae, and the coccyx that consists of four fused vertebrae.
These vertebrae are arranged in such a way as to impart curves to the spine. The shape of the normal spine is curved out in the thoracic or middle back region and curved in in the lumbar or lower back region. These curves allow the spine to remain flexible. It is when these curves become excessive or reversed that problems can arise.
Between the vertebrae are the discs that act as shock absorbers and allow the vertebrae to rock back and forth on one another. Holding these discs and vertebrae in a column are the ligaments. Ligaments are the connective tissues that connect bone to bone and like other soft tissues are prone to shortening or lengthening depending on forces exerted upon them. Ligaments kept in a shortened position for prolonged periods of time will shrink and ligaments held in a stretched position for prolonged periods will undergo creep and become lengthened.
Ligaments are the connective tissues that attach bone to bone and hold this column of vertebrae and discs together. The anterior longitudinal ligament traverses the front of the vertebrae, the posterior longitudinal ligament traverses down the back of the vertebral bodies, and the ligamentum flavum is a relatively elastic ligament that runs along behind the spinal canal.
There is also a ligament that runs from spinous process to spinous process - the supraspinous ligament, and ligaments between the spinous processes - the intraspinous ligaments. There are also strong ligaments that attach L5 to the ilium.
The intervertebral discs lie between the vertebral bodies and act as shock absorbers, allowing the vertebrae to pivot on one another. The outer layers of the disc are like an onion, layer upon layer. The outer layers consist of strong fibrous connective tissues that hold the gelatinous of the nucleus pulposus in. The nucleus pulposus is a gelatinous substance that dries out as we age. Studies have shown that, like a jelly donut, this substance shifts depending on forces exerted upon it.
Knowing this we can do back stretches that influence the position of the nucleus pulposus.
When I discuss discs with patients I like to compare them to a jelly donut. In very simplistic terms the hydrostatics are similar.
