Physical Examination
When you visit a healthcare professional for back pain, they will likely start by conducting a physical examination. The purpose of this examination is to evaluate your symptoms and assess your range of motion and muscle strength. These tests can help your healthcare provider determine the cause of your back pain and develop an appropriate treatment plan.
Evaluation of symptoms
During the physical examination, your healthcare provider will ask you about your symptoms. They will want to know how you would describe the pain, whether it is sharp or dull, constant or intermittent, and whether it radiates to other areas of your body. They may also ask about any activities or movements that worsen or alleviate the pain.
Range of motion tests
To assess your range of motion, your healthcare provider may ask you to perform various movements, such as bending forward, backward, and sideways. They will observe how far you can move without experiencing pain or discomfort. This can help them identify any restrictions or limitations in your spine’s mobility.
Muscle strength tests
Muscle strength tests are often conducted to evaluate the strength and function of your back muscles. Your healthcare provider may ask you to perform specific movements or resist against their pressure while they assess the strength and integrity of different muscle groups. This can help them identify any weakness or imbalance that may contribute to your back pain.
Medical History
In addition to the physical examination, your healthcare provider will also gather information about your medical history. This includes details about the pain you are experiencing, such as when it started, how long it has been present, and what activities or events may have triggered it. They will also inquire about any previous injuries or surgeries you have had that may be relevant to your current back pain.
Pain description
Describing your back pain accurately can provide valuable insight to your healthcare provider. Be sure to mention the intensity, quality, and location of the pain. Is it localized to a specific area or does it radiate to other parts of your body? Is it a sharp, stabbing pain or a dull, achy sensation? These details can help your healthcare provider narrow down potential causes and determine which diagnostic tests may be necessary.
Location and duration of pain
It is important to inform your healthcare provider about the exact location of your pain. Is it limited to the lower back, or does it extend into the buttocks, legs, or feet? Back pain that radiates into the lower extremities may indicate nerve involvement. Additionally, providing information about the duration of your pain is essential. Is it a recent occurrence or has it been chronic for months or even years? This information can help your healthcare provider identify possible underlying causes and develop an appropriate treatment plan.
Any previous injuries or surgeries
Previous injuries or surgeries may have an impact on your current back pain. Informing your healthcare provider about any previous accidents, falls, or sports-related injuries can be crucial in understanding the cause of your pain. Additionally, surgeries, such as spinal surgeries or procedures on adjacent areas, may also contribute to your symptoms. Your healthcare provider will factor in this information when determining which diagnostic tests are necessary for an accurate diagnosis.
Imaging Tests
To further investigate the cause of your back pain, your healthcare provider may order imaging tests. These tests provide detailed images of your spine and can help identify any structural abnormalities or damage that may be causing your symptoms.
X-rays
X-rays are commonly used to evaluate the bones in your spine. They can detect fractures, tumors, and abnormalities such as scoliosis or degenerative joint disease. X-rays provide a two-dimensional image and are readily available, making them a quick and cost-effective initial diagnostic tool for assessing back pain.
MRI
Magnetic Resonance Imaging (MRI) uses a powerful magnetic field and radio waves to produce detailed images of your soft tissues, including your spinal discs, muscles, ligaments, and nerves. MRI can help identify herniated discs, spinal stenosis, infections, tumors, or any other soft tissue abnormalities that may be causing your back pain. An MRI provides cross-sectional images, allowing for a more comprehensive evaluation of your spine compared to an X-ray.
CT scan
A Computed Tomography (CT) scan combines X-ray images taken from various angles to create detailed cross-sectional images of your spine. CT scans provide more detailed images of the bones and can detect fractures, tumors, or spinal infections that may not be visible on an X-ray. CT scans are particularly useful for evaluating the bony structures of the spine, including the vertebrae and facet joints.
Laboratory Tests
Depending on your medical history and other symptoms, your healthcare provider may order laboratory tests. These tests can help identify underlying medical conditions that may contribute to your back pain or confirm suspected diagnoses.
Complete Blood Count
A Complete Blood Count (CBC) test provides information about the cells in your blood, including red blood cells, white blood cells, and platelets. Abnormalities in these cell counts can indicate an infection, inflammation, or other blood disorders that may be causing or contributing to your back pain.
C-reactive protein test
The C-reactive protein (CRP) test measures the level of inflammation in your body. Elevated levels of CRP can indicate the presence of inflammation, which may be a sign of infection or an autoimmune condition that could be causing your back pain.
Erythrocyte sedimentation rate
The erythrocyte sedimentation rate (ESR) test measures how quickly red blood cells settle to the bottom of a test tube. A high ESR is a non-specific marker of inflammation in the body and may suggest the presence of conditions such as infection, autoimmune diseases, or certain types of arthritis that can cause or contribute to back pain.
Diagnostic Injections
In some cases, diagnostic injections may be used to help pinpoint the exact source of your back pain. These injections involve the administration of a local anesthetic or a combination of anesthetics and steroids directly into a specific structure in your spine.
Facet joint injections
Facet joint injections are used to determine if the facet joints in your spine are the source of your pain. These joints, located on either side of each vertebra, can become inflamed or arthritic, causing back pain. During a facet joint injection, a local anesthetic is injected into the affected joint to numb the area and relieve pain. If the injection provides temporary pain relief, it suggests that the facet joint is the source of your pain.
Epidural injections
Epidural injections involve the administration of an anesthetic and/or a corticosteroid medication into the epidural space, which is the area surrounding the spinal cord and nerve roots. These injections can help diagnose and treat pain caused by conditions such as herniated discs, spinal stenosis, or nerve root compression. If the injection provides temporary pain relief, it can confirm the suspected diagnosis.
Sacroiliac joint injections
Sacroiliac (SI) joint injections are used to determine if the SI joints, located at the base of the spine, are the source of your pain. These joints can become inflamed or irritated, leading to lower back pain. During the injection, a local anesthetic is injected into the SI joint to numb the area and reduce pain. If the pain is significantly relieved, it suggests that the SI joint is the source of your pain.
Electromyography (EMG)
Electromyography (EMG) evaluates the electrical activity of your muscles and the nerves that control them. It can help determine if your back pain is related to nerve compression or muscle dysfunction.
Nerve conduction studies
Nerve conduction studies are a common component of EMG testing. They involve stimulating a nerve with a mild electrical impulse and measuring the speed and intensity of nerve signals as they travel. This can help identify the presence of nerve damage or compression that may be contributing to your back pain.
Needle electrode examination
Needle electrode examinations involve the insertion of a small, fine needle electrode into specific muscles. This allows your healthcare provider to assess the electrical activity of the muscles and the nerves that supply them. The examination helps identify any muscle or nerve abnormalities that may be causing or contributing to your back pain.
Bone Density Test
Bone density tests, also known as Dual-energy X-ray Absorptiometry (DXA) scans or bone densitometry, measure the strength and density of your bones. These tests are primarily used to diagnose osteoporosis, a condition characterized by low bone density and increased risk of fractures. In some cases, low bone density may contribute to back pain.
DXA scan
A DXA scan is a non-invasive and painless test that measures bone density. It is most commonly performed on the hip and spine. The results of the scan are reported as a T-score and compared to the average bone density of young adults. A T-score of -1.0 or above is considered normal, while a T-score between -1.0 and -2.5 indicates osteopenia (lower than normal bone density) and a T-score of -2.5 or below indicates osteoporosis.
Ultrasound
Ultrasound is another method used to assess bone density. It is particularly useful for evaluating the heel bone (calcaneus). The test is painless and involves the use of high-frequency sound waves to measure bone density. Although not as accurate as DXA scans, ultrasound can provide an estimate of your bone density and help identify individuals who may be at risk for osteoporosis or fractures.
Provocative Tests
Provocative tests are physical examinations designed to reproduce specific movements or positions that provoke or exacerbate your back pain. These tests can help identify the structures or movements that are responsible for your symptoms.
Straight leg raise test
The straight leg raise test is commonly used to assess for the presence of nerve root irritation or compression. During this test, you lie on your back while your healthcare provider raises one of your legs with your knee straight. If you experience pain radiating down the back of your leg, it may indicate nerve root compression, such as from a herniated disc.
Spurling’s test
Spurling’s test is used to assess for cervical nerve root compression. During this test, you turn your head to one side while your healthcare provider gently applies downward pressure on the top of your head. If you experience pain radiating down your arm, it may suggest the presence of nerve compression in your neck.
Femoral stretch test
The femoral stretch test is used to assess for nerve root compression in the lower back. Your healthcare provider will ask you to lie on your back with your legs straight. They will then gently bend one of your knees while extending your hip. If you experience pain traveling down the front of your thigh, it may indicate nerve root compression in your lumbar spine.
Nuclear Medicine Scans
Nuclear medicine scans involve the use of radioactive materials to create images that highlight areas of disease or abnormality. These scans can help identify sources of back pain that may not be apparent on other imaging tests.
Bone scan
A bone scan involves the injection of a small amount of radioactive material into your bloodstream. This material accumulates in areas of increased bone activity, such as those affected by infection, fractures, tumors, or arthritis. A special camera detects the radioactive material and produces images that help identify areas of abnormal bone activity.
PET scan
Positron Emission Tomography (PET) scans involve the injection of a small amount of a radioactive substance, known as a tracer, into your bloodstream. The tracer is taken up by cells that exhibit increased metabolic activity, such as cancer cells. PET scans can help identify areas of abnormal activity in your spine and can be particularly useful in detecting metastatic spinal tumors.
Myelogram
A myelogram is a procedure where a contrast dye is injected into the space surrounding your spinal cord and nerve roots, followed by X-ray imaging or a CT scan. This test can help identify abnormalities such as spinal stenosis, herniated discs, or tumors that may be causing your back pain.
Dye injection
During a myelogram, a radiopaque contrast dye is injected into your spinal canal. The dye helps visualize the spinal cord and nerve roots on X-ray or CT images, highlighting any abnormalities or areas of compression.
X-ray imaging
After the dye is injected, X-ray images are taken to visualize the distribution of the dye and identify any areas of compression or abnormalities in your spinal cord or nerve roots.
Ultrasound
Ultrasound imaging uses high-frequency sound waves to generate real-time images of the structures in your body. It is a non-invasive and radiation-free technique that can help evaluate soft tissues, muscles, and joints in the back.
Musculoskeletal ultrasound
Musculoskeletal ultrasound can help identify abnormalities in the soft tissues and muscles of your back. It can be useful in diagnosing conditions such as muscle strains, ligament tears, or fluid-filled cysts that may be causing your back pain.
Doppler ultrasound
Doppler ultrasound evaluates blood flow within the vessels of your back. It can help identify any vascular abnormalities or blockages that may be contributing to your back pain. Doppler ultrasound is particularly useful when assessing the spine for conditions such as spinal vascular malformations or disc-related vascular complications.
Discography
Discography is a diagnostic procedure that involves the injection of contrast dye into one or more of the intervertebral discs in your spine. This procedure helps identify the exact disc that is causing your back pain.
Contrast dye injection
During discography, a contrast dye is injected into the center of a specific disc in your spine. The dye helps visualize the structure and integrity of the disc on X-ray or CT images. This procedure can help identify degenerative discs, herniated discs, or other disc abnormalities that may be causing your back pain.
X-ray imaging
After the contrast dye is injected, X-ray images are taken to evaluate the structure of the disc and identify any abnormalities that may be contributing to your back pain.
Biopsy
In some cases, a biopsy may be necessary to obtain a tissue sample for further examination. A biopsy can help diagnose specific conditions or rule out underlying causes of your back pain.
Tissue sample extraction
During a biopsy, a small tissue sample is extracted from the affected area in your spine. This can be done using a needle or during a surgical procedure. The tissue sample is then sent to a laboratory for pathological examination.
Pathological examination
Pathological examination involves the analysis of the tissue sample under a microscope to identify any abnormalities or disease processes that may be causing your back pain.
Conclusion
Diagnosing the cause of back pain can be a complex process, as there are numerous potential causes. Physical examination, medical history, and a variety of diagnostic tests can help healthcare providers determine the underlying cause of your back pain and develop an appropriate treatment plan. Remember to communicate your symptoms, provide accurate information about your medical history, and follow your healthcare provider’s recommendations to ensure an accurate diagnosis and effective management of your back pain.
