Alteration of Motion Segment Integrity

SOURCE: Dynamic Chiropractic

By Jeffrey Cronk, DC, CICE

Sometimes the internal discourse that is common in our profession seems to get in the way of our acceptance of real help so that we can expand our profession and better serve our patients. Alteration of motion segment integrity (AOMSI) is a significant gift from the AMA that allows us to methodically locate, substantiate and objectively prove the severity of the spinal subluxation. Of course, it comes as a gift only as long as we handle it with a high level of responsibility.

Alteration of motion segment integrity is determined by exact mensuration procedure published in the AMA Guides to the Evaluation of Permanent Impairment. It is a spinal subluxation that can be objectively identified with a high degree of accuracy, especially when one acknowledges the advancements that have occurred in assessment of stress imaging (X-ray, DMX).

Please remember that some of the most significant advancements in functional radiology assessment came from information gained from our profession’s very first federal research grant, awarded in the mid 1970s. It was University of Colorado scientist Chung Ha Suh, PhD, who secured the first chiropractic funding from the National Institutes of Health (NS 12226 01A1). Suh’s main areas of research focused on the development of computerized, kinematic models of the spine and three-dimensional, distortion-free X-ray analysis. This research improved our ability to more accurately measure articular deformations such as AOMSI.

Forward Head Posture

Forward Head Posture

The Chiro.Org Blog

Have you dropped by the Forward Head Posture Page lately?

There have been several new articles added recently.

According to Kapandji (Physiology of the Joints, Volume III), for every inch your head moves forwards, it gains 10 pounds in weight, as far as the muscles in your upper back and neck are concerned. That’s because because they have to work that much harder to keep the head (chin) from crashing onto your chest. This abnormal positioning also forces the suboccipital muscles (the ones that raise the chin) to remain in constant contraction, putting pressure on the 3 suboccipital nerves.

Chapter 3: Basic Factors of Biodynamics and Joint Stability

The techniques used for analyzing static positions of the body are only approximate inasmuch as forces accompanying movement incorporate such dynamic factors as acceleration, momentum, friction, the changing positions of rotational axes, and the resistance and support offered by tissues other than muscles. This chapter discusses the basic concepts and terms of biodynamics, biomechanical stress, and the biomechanical aspects of articular cartilage pertinent to the clinical setting.

Structural Motion

The study of dynamics is concerned with loads and the motions of bodies (kinematics) and the action of forces in producing or changing their motion (kinetics). Kinematics lets us describe the characteristics of motion position, acceleration, and velocity such as in gait or scoliotic displacements. Here we are concerned with the position of the center of mass of the body and its segments, the segmental range of motion, and the velocity and direction of their movements. In kinetics, we become concerned with the forces that cause or restrict motion such as muscle contraction, gravity, and friction. A complete biomechanical analysis of human motion or motion of a part would include both kinematic and kinetic data.

Motion can be defined as an object’s relative change of place or position in space within a time frame and with respect to some other object in space. Thus, motion may be determined and illustrated by knowing and showing its position before and after an interval of time. While linear motion is readily demonstrated in the body as a whole as it moves in a straight line, most joint motions are combinations of translatory and angular movements that are more often than not diagonal rather than parallel to the cardinal planes. In addition to muscle force, joint motion is governed by factors of movement freedom, axes of movement, and range of motion. (more…)

Chapter 7: CLINICAL BIOMECHANICS OF THE CERVICAL SPINE

This chapter considers those factors that are of biomechanical and related clinical interest imperative to the satisfactory evaluation of common or not infrequent cervical syndromes. The discussion assumes that the physician is skilled in taking a thorough clinical history and performing the basic physical, orthopedic, neurologic, and roentgenographic examination procedures. The kinesiology and kinematics of the neck, the effects and mechanisms of cervical trauma, and a number of clinical problems are discussed that are pertinent to the diagnosis and management of musculoskeletal cervical disorders.

General Aspects of Cervical Trauma

Blows to the head or neck may result in unconsciousness, but most blows do not. Rather, the effect is a “subconcussive” or “punch drunk” effect for a few moments. This state may be the effect of a severe blow to the head or the cumulative effects of many blows. It is assumed that the reader is well acquainted with the proper emergency procedures involved in head and neck trauma.

The anterior and lateral aspects of the neck contain a wide variety of vital structures that have no bony protection. Partial protection is provided by the cervical muscles, the mandible, and the shoulder girdle. After spinal injury, a careful neurologic evaluation must be conducted. Note any signs of impaired consciousness, inequality of pupils, or nystagmus. Do outstretched arms drift unilaterally when the eyes are closed? Standard coordination tests such as finger-to-nose, heel-to-toe, heel-to-knee, and for Romberg’s sign should be conducted, along with superficial and tendon reflex tests. For reference, the segmental functions of the cervical nerves are listed in Table 7.3.

Cervical spine injuries can be classified as being:

(1) mild (eg, contusions, strains);(2) moderate (eg, subluxations, sprains, occult fractures, nerve contusions, neurapraxias);(3) severe (eg, axonotmesis, dislocation, stable fracture without neurologic deficit); and(4) dangerous (eg, unstable fracturedislocation, spinal cord or nerve root injury).Soft-Tissue Injuries of the Posterolateral Neck

CERVICAL CONTUSIONS

Contusions in the neck are similar to those of other areas. They often occur in the cervical muscles or spinous processes. Painful bruising and tender swelling will be found without difficulty, especially if the neck is flexed. They present little biomechanic significance unless severe scarring occurs.

DIRECT NERVE TRAUMA

Nerve trauma occurs from contusion, crushing, or laceration.

Neurapraxia. Recovery of nerve contusion usually occurs within 6 weeks. Nerve contusion may be the result of either a single blow or through persistent compression. Fractures and blunt trauma are often associated with nerve contusion and crush. Peripheral nerve contusions exhibit early symptoms when produced by falls or blows. Late symptoms arise from pressure by callus, scars, or supports. Mild cases produce pain, tingling, and numbness, with some degree of paresthesia. Moderate cases manifest these same symptoms with some degree of motor and/or sensory paralysis and atrophy.

Axonotmesis. After nerve crush, recovery rate is about an inch per month between the site of trauma and the next innervated muscle. If innervation is delayed from this schedule or if the distance is more than a few inches, surgical exploration should be considered.

Neurotmesis. Laceration from sharp or penetrating wounds is less frequently seen than tears from a fractured bone’s fragments. Surgery is usually required. Stretching injury typically features several sites of laceration along the nerve and is usually limited to the brachial plexus.

INTRODUCTION

Strengthening exercises for the muscular system play an essential role in the chiropractic management of various neuromusculoskeletal disorders. Knowledge of various training methods and exercise techniques are thus among the most important requirements for effective treatment. [1] Properly conducted individual exercise programs help prevent many injuries and serve to shorten the recovery period necessary to restore the patient back to health. [2] Exercise programs can be designed to increase strength, aid weight loss, increase cardiorespiratory efficiency, or simply improve overall musculoskeletal performance.

All exercise programs should have specific goals in mind. The cornerstone of exercise is Davis’ Law, or the (SAID) principle that states that the body makes specific adaptation to imposed demands. [3] The more specific the exercise, the more specific the adaptation. Exercise, therefore, should be as specific as possible to the individual’s goals and needs. (more…)
