Many researchers seem to believe that low back pain is a modern problem. For instance, Waddell writes, “Observations of natural history and epidemiology suggest that low-back pain should be a benign, self-limiting condition, that low back-disability as opposed to pain is a relatively recent Western epidemic … .” In 2008, Martin et al found that, “The estimated proportion of persons with back or neck problems who self-reported physical functioning limitations increased from 20.7%… to 24.7% … 1997 to 2005,” which certainly shows that it is a growing problem and therefore likely to be worse now than in the past. A Spanish study (Jiménez-Sánchez et al) showed that “serious” musculoskeletal complaints (including a great deal of back pain, presumably) increased significantly from 1993 to 2001. Finally, Harkness et al did a nice job in 2005 of comparing rates of musculoskeletal pain (including low back pain) 40 years apart in the northwest of England, and found a large increase. In his books, Sarno also strongly portrays low back pain as a modern problem — though he doesn’t defend it . It’s hard to say if back pain actually is a modern problem, or whether it just tends to be described as such. Remember that human beings have a strong tendency to sensationalize and dramatize! Harkness pointed out in her study that the appearance of an increase “could be partly explained by the ‘worried well’. The ‘worried well’ are those patients who are concerned about their health, and attend their GP to seek reassurance about their well-being.” This is a great example of how hard it is to really be sure of anything!

Plain X-rays are generally not considered useful in the evaluation of acute back pain, particularly in the first 30 days. In the absence of red flags, their use is discouraged. Their use is indicated if there is significant trauma, mild trauma in those older than 50 years of age, people with osteoporosis, and those with prolonged steroid use. Do not expect an X-ray to be taken.
Massage might be beneficial for patients with subacute and chronic nonspecific low back pain, especially when combined with exercises and education.24 Acupressure or pressure point massage technique was more effective than classic massage. A second systemic review found insufficient evidence to determine efficacy of massage for acute low back pain.10 Evidence was insufficient to determine effects of the number or duration of massage sessions.
Magnetic resonance imaging (MRI) scans are a highly detailed test and are very expensive. The test does not use X-rays but very strong magnets to produce images. Their routine use is discouraged in acute back pain unless a condition is present that may require immediate surgery, such as with cauda equina syndrome or when red flags are present and suggest infection of the spinal canal, bone infection, tumor, or fracture.
Spinal manipulation: The U.S. Agency for Healthcare Research and Quality recognizes spinal manipulation by chiropractors and osteopaths as effective for acute low-back pain. Its effectiveness for treating chronic back pain is less well established. Some researchers suggest that early manipulative treatment for acute back pain may prevent chronic problems from developing. Other doctors warn against some chiropractic manipulations, particularly those that involve rapid twisting of the neck. Spinal manipulation can be considered a form of conservative care for the treatment of acute and chronic back pain as it is not invasive and does not employ prescription medications.
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).
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.
Does massage really ease back pain once you leave the table? A recent study found that one weekly massage over a 10 week period improved pain and functioning for people with chronic back pain. Benefits lasted about six months but dwindled after a year. Another hands-on approach is spinal manipulation. Performed by a licensed specialist, this treatment can help relieve structural problems of the spine and restore lost mobility.
