Care must be taken to differentiate these sprains from a sacroiliac, hip, rectal, or pelvic lesion. During the 1990s and 2000s a large number of papers have been published on lumbar motor control training, led by researchers from the University of Queensland. PLUMB LINE ANALYSIS With one hand, firm pressure is applied by the examiner over the suspected sacroiliac joint, fixing the patient's anterior pelvis to the table. During evaluation, the patient should be instructed to sit on an examining stool, thus immobilizing the pelvis, and asked to rotate the trunk first to one side and then to the other. This pressure should elicit further tissue relaxation. Asymmetrical fullness of the suboccipital musculature usually indicates upper cervical rotation. The bones of the pelvic girdle are well supplied with ligaments for stabilization (Fig. Frequently associated is a lateral shift (scoliosis) away from the midline. Clinical tests will elicit signs of sacroiliitis and rigidity of the lumbar and later the thoracic spine during forward flexion. With the patient in the prone position, a re-examination by palpation of the spinous processes, transverse processes, and paravertebral musculature should be made. Chronic hypertonicity of the intertransverse muscles is another common cause of low-back pain. If severe, this can force the inferior process into the IVF and produce direct impingement of the IVF contents. With the patient in the lateral recumbent position, deep gluteal palpation will reveal taut cords. (2) vigorous jerky movements of short duration, or Subluxations also frequently occur at the point where a primary curve merges into its compensatory curve. There is a high incidence of trauma and strenuous physical activity in the history of spondylolysis such as fatigue fractures from falling on the buttocks. However, an entrapped fragment or protrusion would not be benefited and may be aggravated. They are more frequently the result of a misstep, an awkward twist during flexion, or torsional overexertion (eg, shoveling). In bending, the knees should not flex. The result of these two measurements offers an appraisal of the degree of instability present. Perfect synchronization of these lumbar-sacral-pelvic motions must be achieved to obtain minimal biomechanical stress. Quite frequently, psychologic stress superimposed on a biomechanical fault precipitates episodes of backache. With the other hand, the ankle is grasped and an attempt is made to extend the leg at the knee. Sensory to skin over posterolateral aspect of leg and lateral foot; heel; over upper third of lateral aspect of leg below knee; over anterolateral aspect of leg and dorsum of foot and toes; medial aspect of sole, great toe, 2nd to 4th toes; lateral aspect of sole, 4th and 5th toes; on dorsum of foot between great toe and 2nd toe. Normally, no pain should be felt on this maneuver. Some examiners allow the hyperextended limb to fall from the table edge. The position of the gluteal cleft should be noted. This act stretches the anterior abdominal and iliopsoas muscles and increases intrathecal pressure. Standing Test for Inferior Joint Motion. The patient is asked to raise the knee on the side being tested. For example in the upper spine, if the atlas shows a left lateral shift, right lateral flexion of the head is greater than the same effort to the left. In this position, body weight (plus loading) pulls the sacrum anterior, while taut pelvic extensors pull the ilia posterior. Trauma: Lumbar and Sacral Syndromes With the palpating hand, the examiner places a thumb over the patient's PSIS and exerts pressure, then slides his thumb outward and then inward. In this distortion, the characteristics are an unleveling of spinal support due to anomaly, trauma, or pathology where the structural unleveling of the spine above tends to portray a normal compensatory response if the motion units are functional. In bending, the knees should not flex. Likewise, if symptoms are aggravated by prolonged sitting, it is evident that sustained flexion is causing a mechanical deformation and therapy should emphasize lumbar extension. Hamstring extensibility can be tested passively and dynamically with manual muscle extensibility examination. There is a guarded gait and limited spinal motion, especially spinal flexion due to hamstring tension. Low back disability has an extremely high incidence, and acute strains are frequently superimposed on chronic strains. This results in a reflex contraction of the muscles supplied. The intertransverse spaces of the normal spine open on the convex side and approximate on the concave side. (A) Anterior view. Manual Therapy for the Low Back and Pelvis – A Clinical Orthopedic Approach (2015). During lateral bending in the erect position, considerable rotation accompanies the abduction motion if there is a significant degree of lordosis. It may require 10-20 minutes of complete relaxation in this position for the protruded anulus to recede. When signs of extension weakness are evident, differentiation must be made between weak spinal extensors and weak hip extensors. The distortion is associated with muscular weakness or spasticity such as of the psoas in the lumbar spine or the sternocleidomastoideus in the cervical spine; postural imbalance and interference to normal locomotive effort; muscular soreness and fatigue; irritative microtrauma to all involved vertebral motion units; compensatory curvatures; and biomechanical stress transmitted throughout the spinal column. Almost any type of bacterial infection may originate in or extend to the sacroiliac joints. If Lasegue's supine test is positive at a given point, the leg is lowered below this point and dorsiflexion of the foot is induced. Because of chronic lumbar overstress, heavy lifting is commonly associated with an increased incidence in spondylolysis and disc herniation at the lower lumbar area. Neurologic signs and Lasegue's tests are usually negative. Action: Primary spine extensor, whilst aiding in the control of spine flexion. Winged scapulae or blades failing to lie smoothly upon the chest wall should be sought. Extension occurs from above downward. Heavy loads or severe blows, especially at an unguarded moment, may rupture some associated ligaments and/or subluxate the joint. Spondylolysis is similar to spondylolisthesis in that there is also a defect in the pars interarticularis, but there is no anterior slipping of the vertebral body. BASIC INVESTIGATIVE APPROACH The sacral parasympathetics as well as the thoracolumbar sympathetics innervating the viscera are accompanied by a meager but sufficient quantity of viscerosensory fibers. The most common causes of nondisc functional pain are postural fatigue, spinal strains (acute and chronic), and IVF syndromes. During the first 60° of flexion, the pelvis is locked by the posterior pelvic muscles. Special roentgenographic and laboratory analyses are necessary if symptoms do not respond as anticipated. Before concluding this part of the examination, the examiner should test the effects of repetitive loading in flexion. In posterior root irritation, pain can be felt in the dermatome, myotome, sclerotome, and possibly in the viscerotome. DISTORTION SIGNS Naffziger's Test. In the chronic stage, the muscles become fibrotic and the paravertebral ligaments shorten, often to an area extended quite lateral from the midline. (4) biomechanical impropriety of the pelvis in static postural accommodation and locomotion. Longissimus Capitus (head rotation/pulls backward) 5. If the patient's pain increases, a disc involvement or area of inflammation is probably the factor involved. These six major functional groups of the lumbar spine are not mutually exclusive. Rotation right. As few chairs contain a lumbar roll to maintain the normal lordosis, the longer a person sits in a relaxed position, the more the muscles relax and weight-bearing stress must be absorbed by the ligaments. These anterior ligaments can be divided into superior and inferior ligaments. When the segments are asymmetrically loaded, the bodies of the involved segments normally deviate farther from the midline than their spinous processes. There is a guarded gait and limited spinal motion, especially spinal flexion due to hamstring tension. This hardening is usually followed by hypertrophy or exostosis. Fibers on the side of the concavity shorten, and fibers on the side of the convexity lengthen. Frequent trauma to the articular structures as a result of excessive joint motility results in repetitive, low force injury. More lost working hours are attributed to this affliction than any other factor, and the vast majority of these complaints find their cause in biomechanical failures. A positive sign of joint inflammation or sprain is seen with an increase in pain; however, absence of pain does not necessarily rule out chronic sacroiliac involvement. It is for this reason that the direct cause of a sacroiliac sprain-subluxation may not be within the joint itself and recurrence can only be avoided if the coupled joints, ligaments, and muscles are kept elastic. Then the floor-fingertip distance is measured. Local pain in the spine does not positively indicate nerve compression; it may indicate the site of a strain, sprain, or another lesion. If the vertebral bodies were not subject to the law of rotation during bending, the spine would have to lengthen during bending and its contents (ie, cord, cauda equina, and their coverings) would be subjected to considerable stretch. Muscles connect to the vertebrae and bones via ligaments, flexible bands of fibrous tissue. Cineroentgenography shows that this is true only when the sacroiliac and pubic articulations are completely fixated in all directions of movement. This produces excessive stress at the lower lumbar facets, and the "catch" comes at this angle. For example, if the sacral base slips anteroinferior on the right with the right ilium rotating posteriorly on the sacral base, the pelvis as a whole will tend to rotate anteriorly on the right to keep body weight centered over the head of the femur because the acetabulum has translated superiorly. If there is a right structural scoliotic deviation of the lumbar area, the patient sitting, with pelvis fixed, will find it easier to rotate the torso to the right than to the left. A stiff distortion of the spinal column may suggest spondylitis deformans. The distorted articular surface may produce chronic instability from erosion and degeneration, leading to reactionary osteophytoses which, in turn, are subject to fracture. The fracture line is usually through the sacral foramina, which weaken the bone at these points. These anterior ligaments can be divided into superior and inferior ligaments. In the well-conditioned individual, IVD conditions are more often, but not exclusively, attributed to extrinsic blows or wrenches. If this does not occur, it is atypical and most likely pain producing. The trunk will usually be flexed in the basic protective position. It is usually impossible to tell what is primary and what is secondary as each can cause the other. Regardless of the degree of lordosis, L3 is usually fairly horizontal, thus it is subjected to minimal shear forces. It is often compressed in the IVF by a subluxated articular facet and less often by a herniated disc or a spur from the posterior aspect of the vertebral body. Marked demonstrable muscle weakness, pronounced atrophy, and intractable radicular pain. A 1/4–1/2-inch excursion should be felt as the ischium moves anterosuperior and lateral on the sacrum. Winged scapulae or blades failing to lie smoothly upon the chest wall should be sought. Cremasteric Reflex. STANDING HYPEREXTENSION (2) the direction of excessive rotary forces to the lumbar spine, leading to disc failure; Intervertebral disc conditions are more often, but not exclusively, attributed to extrinsic blows and wrenches. Pain from mechanical causes is sharp, acute, and occurs immediately. ), Note: Thoracolumbar Fascia and Abdominal Aponeurosis, In addition to the fibrous fascial ligaments and joint capsules of the lumbosacral and sacroiliac region, further stabilization is provided by the thoracolumbar fascia posteriorly and the abdominal aponeurosis anteriorly. Shape and Size. If at least rest, warmth, or stretching exercises are not offered, chronic strain can lead to the typical posture of spinal "sag," exhibiting drooping shoulders, a rounded thoracic region, inhibited rib and diaphragm motion, shallow breathing, lumbar hyperlordosis, anterior longitudinal ligament stretching, anterior pelvic rotation, chronic apophyseal synovitis, backache, disc collapse, bulging abdomen, visceroptosis, digestive disturbances, flatulence, and chronic tiredness. An understanding of Lovett's principles and the basic types of lumbar scolioses offers insight into distortion analysis. Palpation should be done with the fingerpads upon the interspinous spaces. Furthermore, both of these movements will be sluggish, quickly reaching their limits and pulling the sacrum into a visible distortion. Increased tone tends to pull the lower half of the spine and the pelvis anterior, lateral, and superior. (2) there is increased tenderness over the lateral portion of the inguinal ligament, and This reflex is also initiated when a gloved finger is inserted into the rectum such as during a prostate examination. However, if the lumbar spine is relatively flat or if the lateral bending is performed in the sitting position, the amount of associated rotation is minimal. ROENTGENOGRAPHIC CONSIDERATIONS A negative scoliosis is indicative of marked muscle involvement. In common pelvic mechanical problems on the side of involvement. In this context, Janse feels that the muscles most directly affected by this noxious reflex from an irritated viscus are the multifidi, rotatores, intertransversarii, and psoas major muscles. It should also be noted that atlanto-occipital, atlantoaxial, and coccygeal disrelation with partial fixation places a degree of traction upon the cord, dura, and dural sleeves in flexion-extension and lateral bending efforts. Unless corrective action is taken, this state becomes progressively degenerative as the result of the abnormal weight distribution during static and dynamic activity. The associated pain may be immediate or not occur for several hours after the tissues warmed by physical activity begin to cool. Please review the complete list of available books. THE LUMBAR VERTEBRAE If the hamstrings are normal and the paravertebral muscles are tight, pelvic motion is free but lumbar flexion is restricted. In primary lumbar scoliosis, the articular surfaces are no longer parallel and the result is articular friction leading to impingement, erosion, and arthritis. The paralysis is flaccid. In addition, emotional factors must be considered. The explanation is the same as that previously given for the cause of many vertebral subluxations. There may be a history of low back complaints with evidence of organic or structural disease. But even these may sometimes be involved. AIIS, anterior inferior iliac spine. SEGMENTAL FAULTS (2) The side of major misalignment is on the side to which the L5 has rotated, regardless of what direction the ilia have rotated. If this rebound test causes a marked increase in pain and muscle spasm, then a disc involvement is said to be suspect. Courtesy Joseph E. Muscolino. An understanding of Lovett's principles and the basic types of lumbar scolioses offers insight into distortion analysis. Body weight during development wedges the sacrum between the innominates because of their peculiar laterally inclined planes. Anular and end plate tears lead to fragmentation, displacement, and the development of scar tissue. Even a trace of sensory abnormality, objective or subjective, should immediately raise the suspicion of injury to the spinal cord or cauda equina. The cause is unknown. These disorders are said to seriously affect 25% of females and 18% of males over 70 years of age. However, if the facets deviate in their direction of movement, the unparallel articulating surfaces "scrub" upon one another. In the horizontal positions, the lumbar spine is in extension when a person is supine on a firm mattress or prone on either a firm or soft mattress. Olsen recommends the use of Fergurson's angle, where the body of L3 is X'ed and a line is dropped perpendicular from the center of the vertebral body. Also see Acute Lumbosacral Angle Syndromes and Table 12.13 in this chapter. When the gluteus medius shortens to abduct the hip when the patient is laterally recumbent, the contraction tends to separate the ilium from sacrum. (1) an adaptive lumbar scoliosis away from the side of pain, leading to biomechanical changes in the thoracic and cervical regions; 7. Normal symmetrical facets glide with little friction produced. Body weight during development wedges the sacrum between the innominates because of their peculiar laterally inclined planes. The doctor stabilizes the patient's pelvis by cupping his hands over the ASISs and exerting moderate pressure. Lasegue's Rebound Test. Chronic hypertonicity of the intertransverse muscles is another common cause of low-back pain. If pelvic rotation fails to occur, the first suspicions should be sciatic irritation, hip restriction, or tight hamstrings. The hyperextension of the hip exerts a rotating force on the corresponding half of the pelvis. It may not occur until several minutes or hours after an injurious event has taken place. If the superior sacroiliac joint or the symphysis pubis is locked, the sacrum and ilium will move as a unit, the thumbs will not separate appreciably, and the sacral tissues (ligaments and spinal muscle attachments) will remain taut. Kernig's Neck Test. If, on the other hand, discomfort is experienced or augmented only after the legs have been raised beyond 50° and the small of the back wedges firmly against the towel, lumbosacral involvement should be the first suspicion. (2) alongside the L5–S1 spinous processes. Although great curves in the lumbar area are commonly seen, most of the apparent rotation seen is from distortion of the lumbar spine's base, tipping, and the lumbar lordosis viewed out of its normal plane. In all cases, the patient should be alerted that jugular pressure may result in vertigo. Reiter's syndrome also has its highest incidence among males 20–40 years of age. The major predisposing factors to low back pain appear to be a poor sitting posture, a loss of motion within the normal range of lumbar extension, and/or excessive hyperflexion activities. With the patient sitting, the examiner's thumbs are placed on the PSISs and the patient is asked to fan his knees open and close several times. An increase in pain is a positive indication of a sacroiliac lesion if the possibility of a hip lesion has been eliminated. Such a sign signifies either ipsilateral sacroiliac locking where the sacrum and ilium move as a whole or muscular contraction that prevents motion of the sacrum on the ilium. This is more easily determined by dotting the spinous processes with a skin pencil when the patient is in the standing position. This tends to separate the sacroiliac joints. The examiner places one hand under the heel of the affected side and the other hand is placed on the knee to prevent the knee from bending.       AVULSIONS Injuries to the lumbar cord or its tail occur from vertebral fractures, dislocations, or penetrating wounds in severe accidents. Lateral bending is then conducted, bilaterally. However, any mechanical force that will stress or deform receptors, with or without overt damage, or any irritating chemical of sufficient concentration will depolarize unmyelinated fibers and enhance afferent activity. In suspected cases where no obvious gross slipping has occurred, the Meschan method is used on the lateral projection. In the upright position, the greater the lordosis, the greater the compressive forces upon the posterior elements of the vertebral segments and the greater the shearing forces on the discs. This inhibits pelvic tilt and hyperlordosis. Standing Test for Inferior Joint Motion. A thumb is placed on the sacral apex and the other thumb on the ischial protuberance. Can produce unilateral flexion and rotation. As in other areas of the body, x-ray views of the spine must be chosen according to the part being examined and the injury situation. The features of this deformity are scoliosis and/or alteration of the normal A-P curves where there is no apparent structural basis. (3) there is increased tenderness over the origin of the sartorius muscle. Associated weak abdominals will contribute to faulty pelvic stabilization. The test is made at the end of extension by firm thumb pressure on the sacral apex while the other thumb is on the PSIS. However, we should also avoid the tendency to generalize that all such symptoms and signs are referred. Horizontal shear forces appear to be the most damaging forces for disrupting the ligamentous strapping between vertebrae. A folded towel is placed transversely under the small of the patient's back. When the apex of the lumbar curve is too low, a posterior subluxation will most likely be found in the upper lumbar area. Thus, sciatica that is aggravated by both standing and supine flexion suggests a disc involvement. When lumbar and pelvic muscles become fibrotic, a search should be made for other areas within the lower extremity such as in the hip flexors and the gastrocnemius (eg, the "high heel" syndrome). TESTING MUSCLE WEAKNESS This test is usually contraindicated in the elderly. The muscles and ligaments that hold the trunk erect are much stronger as a whole than those of the pelvis. Marginal spurring, lipping, and the consequence of osteophytic formation ensues. If this does not occur, it is atypical and most likely pain producing. See Table 12.12. This is more easily determined by dotting the spinous processes with a skin pencil when the patient is in the standing position.
