Low back pain is the most common diagnosis seen in many physical therapy clinics, and it affects nearly 85-90% of Americans at one time or another. It is the second leading cause of visits to a doctor, after the common cold. Low back pain is also the leading cause of lost time at work, and billions of dollars are spent each year diagnosing and treating low back pain.
What Exactly Is the Low Back
The low back, or lumbar spine, consists of five bones, or vertebrae, stacked upon one another. Between the bones are soft, spongy shock absorbers called intervertebral discs. The spinal cord and nerves are protected by these bones. Multiple ligaments and muscular attachments provide stability and mobility to the lumbar spine.
What Causes Low Back Pain
The three most common causes of low back pain are poor sitting posture, frequent forward bending, and lifting heavy items.
Although trauma may be a cause of low back pain, most often there is no apparent reason for the onset of symptoms. Thus, it is thought that repetitive strain on the structures around the lumbar spine is the main cause of low back pain.
When to Seek Help
Remember, low back pain can be a serious problem and it is highly recommended to consult a physician, physical therapist or other qualified health care provider if low back symptoms are present and are significantly limiting function and mobility. Also, there are a few signs and symptoms that require immediate medical attention. These include, but are not limited to:
- Loss of muscular control. If sudden loss of muscular control in the hip, thigh, calf, shin, or toes occurs, an immediate referral to a physician is warranted. If you are not able to lift your leg to walk, rise from a chair, or walk up stairs, you may have a serious problem that needs medical attention.
- Loss of bowel or bladder function. If structures in the low back are compressing the spinal cord or nerves that control bowel and bladder function, loss of bowel or bladder control may occur. Most often, the primary symptom is inability to urinate. If this occurs with onset of low back pain, it should be considered a medical emergency and immediate medical attention is required.
- History of cancer or metastatic disease. Although rare, it is always a good idea to see a physician if you have a recent onset of low back pain and a history of cancer. Simple tests can be performed to rule out metastatic disease and proper treatment can be initiated.
- Recent significant trauma. Although rare, low back pain can be brought on by trauma such as falls or motor vehicle accidents. If significant trauma has taken place and caused acute low back pain, a visit to a physician to rule out a fracture is required before initiating treatment.
Where is Low Back Pain Felt
Symptom location may also be helpful to identify the cause of the problem and to start self-management of low back pain. The most common symptoms coming from the lumbar spine can be found here.
What to do When Low Back Pain Occurs
If you are currently experiencing low back pain, one or two days of rest is indicated. After this short time period, gentle self-care exercises should be started to restore mobility and decrease pain. Some basic exercises to try can be found here. Since poor posture is a major cause of low back pain, maintaining proper posture is important. Use a small pillow or towel roll to support the spine while sitting. Remember, if pain prevents you from exercising or if pain persists for more than 2-3 weeks, a visit to a physician, physical therapist, or other health care provider is necessary.
What to Expect from Physical Therapy
When low back pain is persistent or interferes with normal activities, a visit to a physical therapist may be necessary. When you go to a physical therapist, he or she will perform an initial evaluation on the first visit. Be prepared to move around quite a bit, so be sure to wear comfortable clothing and make sure that your low back is accessible.
An initial evaluation will consist of several different parts. First, a history about your present problem will be taken. Be prepared to discuss your symptoms and what activities or positions make your symptoms better or worse. Some special questions will be asked to help the therapist determine the nature of your problem and to discover anything that needs immediate medical attention.
The physical therapist will also take measurements of how you are moving. This may include measurements of your range of motion and strength. A postural assessment will also be included in the initial evaluation. From the results of the evaluation, a specific treatment plan will be devised and started. It is important to remember to be an active participant in your treatment and ask questions if you are unsure of what to do.
When an acute episode of low back pain strikes, don't panic. Most studies indicate that acute low back pain is short lived and most symptoms resolve spontaneously in a few short weeks. With that in mind, low back pain, although short lived, tends to be episodic in nature. Many times, people have multiple episodes of low back pain during their lifetimes. Recurrent episodes tend to get progressively worse with the passage of time. Therefore, it is important to not only treat the symptoms of low back pain, but also to have a strategy to prevent future low back problems.
One of the most important times to care for your low back is when you have no symptoms. By maintaining proper posture and appropriate strength and mobility in the spine, episodes of low back pain may be avoided completely.
