About 50% of women experience low back pain during pregnancy. Back pain in pregnancy may be severe enough to cause significant pain and disability and pre-dispose patients to back pain in a following pregnancy. No significant increased risk of back pain with pregnancy has been found with respect to maternal weight gain, exercise, work satisfaction, or pregnancy outcome factors such as birth weight, birth length, and Apgar scores.
Biomechanical factors of pregnancy that are shown to be associated with low back pain of pregnancy include abdominal sagittal and transverse diameter and the depth of lumbar lordosis. Typical factors aggravating the back pain of pregnancy include standing, sitting, forward bending, lifting, and walking. Back pain in pregnancy may also be characterized by pain radiating into the thigh and buttocks, night-time pain severe enough to wake the patient, pain that is increased during the night-time, or pain that is increased during the day-time. The avoidance of high impact, weight-bearing activities and especially those that asymmetrically load the involved structures such as: extensive twisting with lifting, single-leg stance postures, stair climbing, and repetitive motions at or near the end-ranges of back or hip motion can easen the pain. Direct bending to the ground without bending the knee causes severe impact on the lower back in pregnancy and in normal individuals, which leads to strain, especially in the lumbo-saccral region that in turn strains the multifidus.

Clinical Trials
There are many clinical trials sponsored both by industry and the National Institutes of Health. Clinical trials sponsored by the National Institutes of Health related to back pain can be viewed at NIH Clinical Back Pain Trials.
Pain is subjective and is impossible to test objectively. There are no clinical tests that can be objectively verified. Clinical tests are limited to be measured by the patient s perception of how he scores the pain on a scale of 1 to 10. Sometimes and particularly with children a series of emoticons are presented to the patient and the subject is asked to point to an emoticon. Even though some clinical trials succeed in getting regulatory approval for products this is not a proof that this therapy is more effective or even has a benefit. All the test rely on the patients perception. The doctor can not verify whether 5 is a more appropriate score than 1 or 10.
A 2008 randomized controlled trial found marked improvement in addressing back pain with The Alexander Technique. Exercise and a combination of 6 lessons of AT reduced back pain 72% as much as 24 AT lessons. Those receiving 24 lessons had 18 fewer days of back pain than the control median of 21 days.

Treatments with uncertain or doubtful benefit
* Injections, such as epidural steroid injections and facet joint injections, may be effective when the cause of the pain is accurately localized to particular sites. The benefit of prolotherapy has not been well-documented. A 2009 medical review found multiple randomised trials which showed that corticosteroid injections into the facet joints where no more effective than saline injections.
* Cold compression therapy is advocated for a strained back or chronic back pain and is postulated to reduce pain and inflammation, especially after strenuous exercise such as golf, gardening, or lifting. However, a meta-analysis of randomized controlled trials by the Cochrane Collaboration concluded "The evidence for the application of cold treatment to low-back pain is even more limited, with only three poor quality studies located. No conclusions can be drawn about the use of cold for low-back pain"
* Bed rest is rarely recommended as it can exacerbate symptoms, and when necessary is usually limited to one or two days. Prolonged bed rest or inactivity is actually counterproductive, as the resulting stiffness leads to more pain.
* Electrotherapy, such as a transcutaneous electrical nerve stimulation (TENS) has been proposed. Two randomized controlled trials found conflicting results. This has led the Cochrane Collaboration to conclude that there is inconsistent evidence to support use of TENS. In addition, spinal cord stimulation, where an electrical device is used to interrupt the pain signals being sent to the brain and has been studied for various underlying causes of back pain.
* Inversion therapy is useful for temporary back relief due to the traction method or spreading of the back vertebres through (in this case) gravity. The patient hangs in an upside down position for a period of time from ankles or knees until this separation occurs. The effect can be achieved without a complete vertical hang ( 90 degree) and noticeable benefits can be observed at angles as low as 10 to 45 degrees.[citation needed]
* Body Awareness Therapy such as the Feldenkrais Method has been studied in relation to Fibromyalgia and chronic pain and studies have indicated positive effects. Organized exercise programs using these therapies have been developed.
* Ultrasound has been shown not to be beneficial and has fallen out of favor.

Surgery and Emerging treatments
Surgery may sometimes be appropriate for patients with:
* Lumbar disc herniation or degenerative disc disease
* Spinal stenosis from lumbar disc herniation, degenerative joint disease, or spondylolisthesis
* Scoliosis
* Compression fracture
* Vertebroplasty involves the percutaneous injection of surgical cement into vertebral bodies that have collapsed due to compression fractures. This new procedure is far less invasive than surgery, but may be complicated by the entry of cement into Batson's plexus with subsequent spread to the lungs or into the spinal canal. Ideally this procedure can result in rapid pain relief.
* The use of specific biologic inhibitors of the inflammatory cytokine tumor necrosis factor-alpha may result in rapid relief of disc-related back pain. [31]

Conservative treatments
* Exercises can be an effective approach to reducing pain, but should be done under supervision of a licensed health professional. Generally, some form of consistent stretching and exercise is believed to be an essential component of most back treatment programs. However, one study found that exercise is also effective for chronic back pain, but not for acute pain.Another study found that back-mobilizing exercises in acute settings are less effective than continuation of ordinary activities as tolerated.
* Physical therapy consisting of manipulation and exercise, including stretching and strengthening (with specific focus on the muscles which support the spine). 'Back schools' have shown benefit in occupational settings. The Schroth method, a specialized physical exercise therapy for scoliosis, kyphosis, spondylolisthesis, and related spinal disorders, has been shown to reduce severity and frequency of back pain in adults with scoliosis.
* A randomized control trial, published in the British Medical Journal, found that the The Alexander Technique provided long term benefits for patients with chronic back pain.. A subsequent review concluded that 'a series of six lessons in Alexander technique combined with an exercise prescription seems the most effective and cost effective option for the treatment of back pain in primary care'.
* Manipulation, as provided by an appropriately trained and qualified chiropractor, osteopath, physical therapist, or a physiatrist. Studies of the effect of manipulation suggest that this approach has a benefit similar to other therapies and superior to placebo.
* Acupuncture has some proven benefit for back pain ; however, a recent randomized controlled trial suggested insignificant difference between real and sham acupuncture .
* Education, and attitude adjustment to focus on psychological or emotional causes - respondent-cognitive therapy and progressive relaxation therapy can reduce chronic pain.

Short-term relief of Back Pain
* Heat therapy is useful for back spasms or other conditions. A meta-analysis of studies by the Cochrane Collaboration concluded that heat therapy can reduce symptoms of acute and sub-acute low-back pain. Some patients find that moist heat works best (e.g. a hot bath or whirlpool) or continuous low-level heat (e.g. a heat wrap that stays warm for 4 to 6 hours). Cold compression therapy (e.g. ice or cold pack application) may be effective at relieving back pain in some cases.
* Use of medications, such as muscle relaxants, opioids, non-steroidal anti-inflammatory drugs (NSAIDs/NSAIAs) or paracetamol (acetaminophen). A meta-analysis of randomized controlled trials by the Cochrane Collaboration found that injection therapy, usually with corticosteroids, does not appear to help regardless of whether the injection is facet joint, epidural or a local injection. Accordingly, a study of intramuscular corticosteroids found no benefit.
* Massage therapy, especially from an experienced therapist, can provide short term relief. Acupressure or pressure point massage may be more beneficial than classic (Swedish) massage.

Treatment Of Back Pain
The management goals when treating back pain are to achieve maximal reduction in pain intensity as rapidly as possible; to restore the individual's ability to function in everyday activities; to help the patient cope with residual pain; to assess for side-effects of therapy; and to facilitate the patient's passage through the legal and socioeconomic impediments to recovery. For many, the goal is to keep the pain to a manageable level to progress with rehabilitation, which then can lead to long term pain relief. Also, for some people the goal is to use non-surgical therapies to manage the pain and avoid major surgery, while for others surgery may be the quickest way to feel better.
Not all treatments work for all conditions or for all individuals with the same condition, and many find that they need to try several treatment options to determine what works best for them. The present stage of the condition (acute or chronic) is also a determining factor in the choice of treatment. Only a minority of back pain patients (most estimates are 1% - 10%) require surgery.
