<>To ensure a thorough examination, you will be asked to put on a gown. The doctor will watch for signs of nerve damage while you walk on your heels, toes, and soles of the feet. Reflexes are usually tested using a reflex hammer. This is done at the knee and behind the ankle. As you lie flat on your back, one leg at a time is elevated, both with and without the assistance of the doctor. This is done to test the nerves, muscle strength, and assess the presence of tension on the sciatic nerve. Sensation is usually tested using a pin, paper clip, broken tongue depressor, or other sharp object to assess any loss of sensation in your legs. >
<>Neurologic examination of the lower extremities includes strength, sensation, and reflex testing (Table 3), even in the absence of significant sciatica. A straight leg raise test is positive for L4-S1 nerve root pain if it radiates below the knee. A reverse straight leg raise test (extending hip and flexing knee while in the prone position) is positive for L3 nerve root pain if it radiates into the anterior thigh. A central, paracentral, or lateral disk herniation may affect different nerve roots at the same level. Examination of the lumbosacral, pelvic, and abdominal regions may provide clues to underlying abnormalities relating to back pain (Table 15,6 and 25,6,8). >
<>A very important muscle to strengthen is the transverse abdominis, which provides a great deal of support for the lower back. In many people this muscle is extremely weak and this can lead to lower back pain. A very gentle and safe way to strengthen this muscle is shown below. To carry out this exercise lie on your back, place a small cushion under your head, and bend your knees. Your feet should be hip distance apart and placed on the floor. Keep your upper body relaxed and your chin gently tucked in. Take a deep breath in, and as you breathe out focus on drawing your belly button in towards your spine. Hold this gentle contraction for 5 to 10 seconds. As you breathe out relax your tummy muscles. This is a slow, gentle tightening so aim to use less than 25% of your maximum strength. Repeat five times. >
<>Although most cases of back pain are “uncomplicated” and should be able to heal with the treatments mentioned above, sometimes in severe cases other interventions are necessary. Speak to your doctor if you experience lower back pain that does not get better in a few days or weeks. If back pain starts suddenly, look out for other symptoms that may point to a more serious condition, such as a fever, chills, dizziness, numbness or unexplained weight loss. >
<>When you have back pain, sleeping can be hard. It can be a vicious cycle because when you don't get enough sleep, your back pain may feel worse. A poor sleep position can also aggravate back pain. Try lying on your side. Place a pillow between your knees to keep your spine in a neutral position and relieve strain on your back. If you need to sleep on your back, slide a pillow under your knees. Be sure to sleep on a comfortably firm mattress. >
