It's estimated that as many as 75% of us will have some form of back or neck pain at some point in our lifetime. The good news is that most of us will recover without the need for surgery—and conservative care such as physical therapy usually gets better results than surgery.
Degenerative disk disease (DDD) is one cause of back and neck pain. Usually the result of the natural aging process, degenerative disk disease (DDD) is a type of osteoarthritis of the spine.
Your spine is made up of 33 vertebrae that are stacked on top of one another. Between each of these vertebrae is a rubbery piece of cartilage called an "intervertebral disk." ( See images: Degenerative Disk Disease - Cervical | Lumbar ) Imagine the disk as a tire, with gelatin filling the hole in the tire. The tire is called the "annulus," and the gelatin is called the "nucleus." When we're young—under 30 years of age—the disk is made mostly of gelatin. As we age, and sometimes with injury or excessive wear and tear, we start to lose some of that gelatin, and the volume of the disk decreases, resulting in less space between the vertebrae. The disk becomes flatter and less flexible, leaving less space between each set of vertebrae. Sometimes bone spurs form in response to this degeneration of the disk, making the spine stiff. When the rough surfaces of the vertebral joints rub together, pain and inflammation may result. Nerves may become irritated or compressed.
Disk degeneration might occur throughout several regions of the spine, or it might be limited to one disk. When it's part of the natural aging process, the degeneration does not always lead to pain. For some people, however, it can cause a great deal of pain and disability.
You are more likely to develop DDD if you:
You might have mild to intense neck and back pain—or no pain at all:
The pain is often made worse by sitting, bending, and reaching. It may be worse first thing in the morning and after staying in any one position for a long time.
In severe cases, when DDD results in pressure on the nerves, it can lead to numbness, tingling, and even weakness in the arms or legs.
Your physical therapist will conduct a thorough evaluation that includes a review of your medical history and will use screening tools to determine the likelihood of DDD. For example, the therapist may:
If you have muscle weakness and loss of sensation or very severe pain, special diagnostic tests, such as x-rays, may be needed. Physical therapists work closely with physicians and other health care providers to make certain that an accurate diagnosis is made and the appropriate treatment is provided.
Research shows that in all but the most extreme cases (usually involving muscle weakness or high levels of pain), conservative care, such as physical therapy, has better results than surgery.
After the evaluation, if your therapist suspects you have DDD and there are no major medical problems, treatment can begin right away.
Your physical therapist's overall purpose is to help you continue to participate in your daily activities and life roles. The therapist will design a treatment program based on both the findings of the evaluation and your personal goals. The treatment program likely will be a combination of exercises.
Relieve Pain and Increase Movement
Your therapist will design:
This might sound like a lot of exercise, but don't worry: research shows that the more exercise you can handle, the quicker you'll get rid of your pain and other symptoms.
Your physical therapist also might decide to use a combination of treatments:
Once your pain is gone, it will be important for you to continue your new posture and movement habits to keep your back healthy.
DDD usually is a natural result of aging. Research has not yet shown how to prevent it—but you can make choices that lessen its impact on your life and slow its progression. Many physical therapy clinics conduct regular educational seminars to help people in the community learn to take care of their backs and necks. These seminars often are free and provide demonstrations along with written information about exercises for the back and neck, instruction on proper lifting and sitting postures, and other tips to keep your back healthy.
Your physical therapist can help you develop a fitness program that takes into account your DDD. There are some exercises that are better than others for people with DDD, and your therapist will educate you about them. For instance:
The American Physical Therapy Association (APTA) believes that consumers should have access to information that could help them make health care decisions and also prepare them for their visit with their health care provider.
The following articles provide some of the best scientific evidence related to physical therapy treatment of degenerative disk disease. The articles report precent research and give an overview of the standards of practice for treatment of DDD both in the United States and internationally.
