A retrospective review of 100 consecutive pregnancies, involving 94 women receiving prenatal care at a rural western New York family practice, was conducted. Back pain was spontaneously reported to the physician by 23 women in 23 pregnancies. Eleven of the 23 women met diagnostic criteria for sacroiliac subluxation. These criteria include absence of lumbar spine and hip pathology, pain in the sacral region, a positive Piedallu's sign (asymmetrical movement of the posterior superior iliac spines upon forward flexion), a positive pelvic compression test, and asymmetry of the anterior superior iliac spines. A cohort of 11 women meeting criteria for sacroilia subluxation was treated with rotational manipulation of the sacroiliac joints. After manipulative therapy, 10 of the 11 women (91%) had relief of pain and no longer exhibited signs of sacroiliac subluxation.

The purpose of this study was to determine whether surface electromyography (EMG) from the erector spinae muscles could correctly identify individuals with low back pain without a population of elite athletes. A similar technique had previously been successful in identifying low back pain patients within a non-athletic population. A Back Analysis System was used to compute the median frequency of the EMG power density spectrum to monitor metabolic changes in back muscles associated with muscle fatigue. Twenty-three members of a men's collegiate varsity crew team consisting of port (N = 13) and starboard (N = 10) rowers were tested in a laboratory during a fatigue-inducing isometric contraction sustained at a relatively high, constant force. Six of the rowers tested were further classified as having low back pain. A brief test contraction was repeated at a fixed interval following the fatiguing contraction to monitor recovery. A two-group discriminant analysis procedure correctly classified 100% of the rowers with low back pain and 93% of the rowers without back pain on the basis of the median frequency data. The median frequency parameters related to recovery were the best discriminators of back pain. A similar analysis correctly classified 100% of the port rowers and 100% of the starboard rowers on the basis of their spectral parameters. The best discriminating variables in this instance were the median frequency parameters relating to both fatigability and recovery. Results from this study demonstrate that low back pain and asymmetrical muscle function in rowers can be assessed on the basis of EMG spectral analysis.

The coincidence of arthritis with polymyalgia rheumatica (PMR) or temporal arteritis (TA) is not well established. After reviewing the literature we found that 22% of patients suffering from PMR/TA present with additional signs of inflammatory joint involvement. Joints predominantly affected are the sternal junctions, knee and shoulder joints, and the wrists, involvement of the latter frequently resulting in carpal tunnel syndrome. With the exception of sternal junctions, bony erosions are rarely seen. In most cases, synovitis is mild, pauciarticular, asymmetrical, transient and not destructive. Little evidence for inflammatory involvement of spine or sacroiliac joints was found, thus, back pain in these patients should be considered as caused by osteoporosis of the spinal column, mostly due to prolonged corticosteroid treatment.

Back pain patients have restricted spinal movements, and the pattern of disturbance from normal movements may indicate the pathology and the functioning of the lumbar spine. Biplanar radiography was used to measure the three-dimensional intervertebral movements of patients with back pain alone and with back pain plus nerve tension signs demonstrated by restricted straight leg raise. Statistically significant decreases in flexion/extension compared with a normal control group were demonstrated for both groups. Accompanying coupled movements were increased only in those patients without nerve tension signs indicating asymmetrical muscle action, while those with tension signs had symmetric splinting particularly of the lower levels. Conservative treatments had no effect either clinically or on the movements. Caudal epidural injections produced clinical improvement and increased movements demonstrating relaxation of muscle splinting. Biplanar radiography, although capable of differentiating between the groups was not able to provide clinically useful information concerning individual patients with this type of back pain.

A series of 190 patients with lumbar spondylolisthesis treated operatively during the years 1948-80 at the mean age of 15.2 years (8-19 years) and reexamined 4-36 years (mean 11.2 years) later are presented. In 92 of them (48%) scoliosis (more than 5 degrees) in association with olisthesis was seen. The slipping affected the fifth segment in 90 and fourth segment in two patients. The female predominance was characteristic in the scoliotic group. Dysplastic changes of the posterior arc were more often seen in the group of patients with scoliosis than in the nonscoliotic group, and they also presented a more severe grade of slipping and lumbosacral kyphosis. The curve was usually mild and was situated in the lumbar area. Patients with a higher degree of lumbosacral kyphosis and more severe slipping also had a statistically higher degree of lumbar scoliosis. Operative treatment of spondylolisthesis consisted of posterior or posterolateral fusion in situ, but two patients were treated using ventral fusion and three severe cases with removal of loose posterior element. Lumbar scoliosis classified as sciatic type disappeared in 25 out of 39 patients after lumbosacral fusion, suggesting the "sciatic muscle spasm" as an etiologic factor. The torsional type of curve resulting from asymmetrical slipping of the vertebra was also corrected in 19 out of 28 cases after fusion. At follow-up patients with remaining lumbar scoliosis represented more low-back pain than those without any curve. In our opinion lumbosacral fusion is indicated before lumbar curve changes to structural scoliosis in symptomatic patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Series of thermograms from 125 sequential participants were analyzed to determine the usefulness of thermography as a tool for evaluating chronic pain. The stability and symmetry of thermographic patterns over time among both healthy subjects and subjects whose pain remained at the same intensity across several recordings were found to be both high and consistent. This was true only if sensitivity was limited to no greater than 0.5C per color band. Greater sensitivity resulted in the creation of inconsistent asymmetrical patterns among healthy and pained subjects. Thermograms were evaluated by the authors' statistical analysis of the heat patterns and by a ten-member panel of scientists. They found thermography an excellent tool for monitoring changes in pain related to variations in near surface blood flow, such as those occurring during a sympathetic block. It was excellent for relating changes in near surface blood flow to changes in phantom limb pain intensity. There was a good relationship between changes in pain intensity and changes in symmetry of heat patterns for most of the disorders examined. Thermography had mixed usefulness in differentiating pain-free from pained subjects reporting knee pain (test efficiency, 98%), leg pain, and back pain (efficiency, 56%). It consistently indicated painful areas among patients with spinal cord injury.

Beside demonstrating morphological changes, CT enables one to make quantitative measurements of the spinal canal (sagittal diameter, transverse diameter, area of the spinal canal, width of the lateral recess and symmetry of the articular joints). A reduction of the transverse diameter of the spinal canal or asymmetry of the articular joints is associated with an increased and earlier incidence of back pain. In addition, patients with asymmetrical vertebral joints showed more frequent and earlier development of disc prolapse.

The clinical appearance of hamstring shortening in 10 patients referred with diagnosis of asymmetry of the trunk, scoliosis, postural defect, strange gait, and back pain is reported. Additionally, an assessment of knee extension deficit (KED) angle in 575 healthy children (4-15 years of age) was performed. The mean KED angle in the group of healthy children was 35 degrees (SD = 14 degrees). The border between norm and disease was defined as a mean + 2 SD and equaled 63 degrees. A KED angle greater than 60 degrees occurred in 10% of normal children. There was no correlation between age and a value of KED angle. In the study group, KED angle greater than 40 degrees was more frequent in boys. A correlation between disorders within musculoskeletal system and greater KED angle was found. These disorders were more frequent in children with asymmetrical KED angle. In our opinion, the border value of the KED angle is not a good differentiating factor between hamstring shortening and contracture because it does not explain the cause of the disorder.

Spondyloarthropathies are important and common inflammatory arthropathies that occur in approximately 2% of the population. They are often underrecognized. The diagnosis features the presence of asymmetrical, predominately lower limb arthritis and/or inflammatory back pain. The spondyloarthropathies can be subdivided into several disease subcategories, including ankylosing spondylitis, Reiter's/reactive arthritis, psoriatic arthritis, inflammatory bowel disease-associated arthritis and a large group of undifferentiated spondyloarthritis. The interactions between infectious agents and the individual's genetic background are important aetiological factors. Therapies for these conditions include physical therapy, non-steroidal anti-inflammatories and disease-modifying drugs.

Adult scoliosis is defined as a spinal deformity in a skeletally mature patient with a Cobb angle of more than 10 degrees in the coronal plain. Adult scoliosis can be separated into four major groups: Type 1: Primary degenerative scoliosis, mostly on the basis of a disc and/or facet joint arthritis, affecting those structures asymmetrically with predominantly back pain symptoms, often accompanied either by signs of spinal stenosis (central as well as lateral stenosis) or without. These curves are often classified as "de novo" scoliosis. Type 2: Idiopathic adolescent scoliosis of the thoracic and/or lumbar spine which progresses in adult life and is usually combined with secondary degeneration and/or imbalance. Some patients had either no surgical treatment or a surgical correction and fusion in adolescence in either the thoracic or thoracolumbar spine. Those patients may develop secondary degeneration and progression of the adjacent curve; in this case those curves belong to the type 3a. Type 3: Secondary adult curves: (a) In the context of an oblique pelvis, for instance, due to a leg length discrepancy or hip pathology or as a secondary curve in idiopathic, neuromuscular and congenital scoliosis, or asymmetrical anomalies at the lumbosacral junction; (b) In the context of a metabolic bone disease (mostly osteoporosis) combined with asymmetric arthritic disease and/or vertebral fractures. Sometimes it is difficult to decide, what exactly the primary cause of the curve was, once it has significantly progressed. However, once an asymmetric load or degeneration occurs, the pathomorphology and pathomechanism in adult scoliosis predominantly located in the lumbar or thoracolumbar spine is quite predictable. Asymmetric degeneration leads to increased asymmetric load and therefore to a progression of the degeneration and deformity, as either scoliosis and/or kyphosis. The progression of a curve is further supported by osteoporosis, particularly in post-menopausal female patients. The destruction of facet joints, joint capsules, discs and ligaments may create mono- or multisegmental instability and finally spinal stenosis. These patients present themselves predominantly with back pain, then leg pain and claudication symptoms, rarely with neurological deficit, and almost never with questions related to cosmetics. The diagnostic evaluation includes static and dynamic imaging, myelo-CT, as well as invasive diagnostic procedures like discograms, facet blocks, epidural and root blocks and immobilization tests. These tests may correlate with the clinical and the pathomorphological findings and may also offer the least invasive and most rational treatment for the patient. The treatment is then tailored to the specific symptomatology of the patient. Surgical management consists of either decompression, correction, stabilization and fusion procedures or a combination of all of these. Surgical procedure is usually complex and has to deal with a whole array of specific problems like the age and the general medical condition of the patient, the length of the fusion, the condition of the adjacent segments, the condition of the lumbosacral junction, osteoporosis and possibly previous scoliosis surgery, and last but not least, usually with a long history of chronified back pain and muscle imbalance which may be very difficult to be influenced. Although this surgery is demanding, the morbidity cannot be considered significantly higher than in other established orthopaedic procedures, like hip replacement, in the same age group of patients. Overall, a satisfactory outcome can be expected in well-differentiated indications and properly tailored surgical procedures, although until today prospective, controlled studies with outcome measures and pre- and post-operative patient's health status are lacking. As patients, who present themselves with significant clinical problems in the context of adult scoliosis, get older, minimal invasive procedures to address exactly the most relevant clinical problem may become more and more important, basically ignoring the overall deformity and degeneration of the spine.
