History and physical exam for low back pain
Exam Overview
A thorough history to evaluate low back pain includes an assessment of:
- Pattern, intensity, and duration of the current episode of low back pain (you may be asked to complete a pain drawing to identify the sites and symptoms of pain). Make sure your doctor understands what brings on or increases your pain and what makes you feel better.
- Spine problems you have had since birth (congenital spine problems).
- Any type of arthritis in your spine.
- Previous episodes of low back pain and treatment.
- Previous accidents or injuries involving the back.
- Family history of low back pain.
- Work history.
- Sports and other leisure activities.
- History of cancer and other illnesses, such as abdominal disease, pelvic disease, or osteoporosis.
- Recent fever or unexplained weight loss.
- Corticosteroid use.
- Your smoking history.
Your doctor or nurse may also give you a written questionnaire to screen for depression or to assess how low back pain is affecting your life, to rate your job satisfaction, and to describe your support system available at home and at work.
During the physical exam, your doctor will ask you to do a series of movements while you stand, sit, and lie down. This makes it possible to assess muscular and sensory problems contributing to your low back pain. The physical exam will also include:
- Observation and measurements.
- Palpation, in which your doctor will feel for tenderness and joint alignment and check pulses in your legs.
- Deep tendon reflex tests.
- Sensation tests.
- Movement tests.
- Straight leg test.
- Muscle strength tests (neurologic testing).
- General abdominal, pelvic, rectal, and leg exams.
The results of these tests will help your doctor see whether your back pain and other symptoms are related to pressure on a nerve and which nerve or nerves may be compressed. Your doctor will use this information to help determine what type of treatment is most likely to be effective.
Why It Is Done
The history and physical examination are the first part of the work-up for low back problems. Your doctor may change or skip some of the tests to avoid further injuring your back.
Results
The history and physical examination for low back pain may provide the following results:
Normal
History does not reveal an obvious cause of the low back pain.
A physical exam does not cause the same type of pain, muscle weakness, or nerve-related symptoms that you have been having.
Your doctor may recommend:
- Nonsurgical treatment (rest, pain relievers, ice, exercise).
- More tests and exams to determine whether some other medical problem is causing your low back pain.
Abnormal
The medical history and physical exam are likely to distinguish between a low back problem related to a muscle strain or overuse and one that is caused by pressure on a nerve or another more unusual problem.
- If your back pain seems to be related to muscle strain or overuse, or if your nerve-related symptoms are not severe, your doctor will likely recommend conservative treatment (rest, pain relievers, ice, exercise) for a period of time to see whether your symptoms improve.
- If your nerve-related symptoms are more serious or if your doctor suspects that there is a more serious problem, he or she may recommend more tests, such as X-ray, magnetic resonance imaging (MRI), computed tomography (CT), or blood tests.
What To Think About
Pain can be related to both physical and emotional causes. When you're stressed, for example, muscle tightness or spasm can set into your back, causing or worsening pain. Similarly, troubling emotions can worsen pain. If you or your doctor have a sense that your pain is being caused or made worse by stress, anger, or other difficult emotions, be sure to plan for specialized treatment. Cognitive-behavioral counseling and biofeedback are two types of treatment that can give you tools for managing your pain.
