The axial skeleton transmits the weight of the head and the trunk and the upper limbs to the lower limbs at the hip joint discount decadron 1mg line. The muscles of the axial skeleton position the head and the spinal column cheap decadron 0.5 mg with visa, and move the rib cage so as to make breathing possible decadron 0.5 mg. They are also re- sponsible for the minute and complex movements of facial features. The vertebral column begins at the support of the skull with a verte- bra called the atlas and ends with an insert into the hip bone (Fig. From a mechanical view- point, it is a flexible rod charged with maintaining the upright position of the body (Fig. The vertebral column fulfills this role with the help of a large number of ligaments and muscles attached to it. A typical vertebra is made of the vertebral body (found anteriorly) and the vertebral arch (positioned posteriorly). Be- tween the vertebral bodies are 23 intervertebral disks that are made of relatively deformable fibrous cartilage. These disks make up approxi- mately one-quarter of the total length of the vertebral column. The shock absorbance characteristics of the vertebral disks are essential for physical activity. The compressive force acting on the spine of a weight lifter or a male figure skater during landing of triple jumps peak at many times the body weight. The numbers in parentheses indicate the number of bones of a certain type (or in a certain subgroup). The vertebral disks are also instrumental in determining the curvature of the spinal column. Most of the body weight lies in front of the vertebral col- umn during standing, walking, and running. The curvatures in the cervical (neck) and lumbar (pelvic) regions are primarily caused by the greater anterior thickness of the disks in that region. The reverse S shape of the vertebral column in the standing position brings the weight in line with the body axis. The bodies of the vertebrae are held together by longitudinal ligaments that extend the entire length of the vertebral column.

It would collapse under its own weight in the absence of the large number of ligaments and muscles that are attached to it.

Assume that the exercise is performed slowly so that equations of static equilibrium hold decadron 1 mg overnight delivery. The length L between the tip of the head of the athlete and his hip joint is 82 cm cheap 1 mg decadron amex. The length Lc between the center of mass of the upper body and the hip joint is 44 cm decadron 0.5 mg overnight delivery. The lever arm d of the erector spinae is 4 cm and is largely insensitive to the angle be- tween the upper and lower body. If we take moments with respect to the point of application of the total joint force in the hip joint, following equation is obtained: Fe? Substituting the input parameter values into this equation, we find Fe 5 2,823 N at u 5 p/4 Fe 5 3,993 N at u 5 p/2 Fe 5 2,823 N at u 5 3p/4 These results suggest that erector spinae is capable of generating forces that are four to five times the body weight. Some of the body dimensions required in the analysis can be obtained by direct measure- ment. Other input parameters such as the weight of a forearm or upper body can be evaluated by knowing the body weight and using it in the tables given in Appendix 2. Admittedly, the input data thus obtained will be approximations to direct measurements. However, the procedure gives a starting point for "back-of-the-envelope" computations. The lever arms of various muscle groups that move a body segment may be the hardest to measure. The data obtained by cadaver studies and by X-ray provide estimates for some of the important lever arms involved in movement and motion (Appendix 2). Consider, for example, the moment arms of the forearm flexors, biceps, and the brachioradialis mus- cles shown in Fig. The moment arm of biceps is nearly equal to zero when the angle between the upper arm and the forearm is 180°. We illustrate the analysis by considering the dependence of the lever arm of biceps brachia on the joint angle. This is a biarticular muscle in which both heads of the biceps arise at the scapula rather than at the prox- imal head of humerus. Additionally, a strong membranous band arising from the tendon of biceps attaches to the ulna. Let a denote the length of the humerus, b denote the distance between the center of rotation of the elbow joint and the point of insertion of bi- ceps on radius, and u be the angle between the humerus and radius (Fig. In this figure the length of the biceps muscle–tendon cord is repre- sented by the letter c and the normal distance from the center of line of application of the biceps force to the center of rotation of the elbow joint by the letter d. Note that d is the moment arm of the biceps force with respect to the elbow joint.

The postdrawing inquiry consequently allowed a closer scrutiny buy 0.5mg decadron overnight delivery, which permits the clinician to apply a wide range of theo- retical constructs to the therapeutic hour order decadron 0.5 mg line. As we move into a comparison of the two HTPs from a quantitative ex- amination buy 0.5 mg decadron mastercard, the raw G IQ score and the good IQ score remained relatively the same (73/83 on the original and 74/80 on the adapted test). The tests differ in the net weighted score IQ (points toward the client’s potential level of functioning), with 10 less IQ points measured on the adapted pro- jective test. Taken as a whole, both tests pointed toward Borderline Intel- lectual Functioning, while the WISC-III score of 85 placed this patient in the low average range. Yet the testing that was administered when the patient was in early adulthood should not be overlooked. The Culture Fair Intelligence Test, an instrument that measures intelligence that is not influenced by cultural background or scholastic training, produced an IQ of 77. In comparison, the IQs from both HTPs are within mere points of each other, which may be due to the fact that both the HTP and the Culture Fair Intelligence test rely little on verbal training; as Craddick (1980) has stated, "Projective tests (such as the Rorschach) are by their very structure more likely to elicit pathological responses than will the WAIS [Wechsler Adult Intelligence Scale], for example" (p. Although this client was able to fully participate in a battery of verbal testing treatment, a clinician’s work with the difficult client often requires a broad knowledge of diverse cultures. These diversities are not relegated only to cultural traditions, religion, and generational differences, but also 136 Interpreting the Art encompass clothing and food preferences, communication styles, morality, control of aggressiveness, and socioeconomic differences. Consequently, cultural variations affect patterns of communicating, behaving, under- standing, and problem solving. However, as related to art therapy, research has indicated that "children up to age five, regardless of cultural or ethnic origins, follow a specific pattern.... This guide was taken in part from Lowenfeld and Brittain’s (1982) research on child- hood developmental stages, yet a quick search of their index for cultural is- sues finds them linked only with aesthetics. There is no mention of how culture affects art development and no discussion of any cross-cultural commonalities that may exist within childhood renderings. To address this deficiency in the research Alter-Muri (2002) began "an informal inquiry into how Lowenfeld’s theories might function today" in which "one hundred and fifty-six drawings by children ages 3 to 11 from schools in Switzerland, Denmark, Germany, France, and Hungary were collected" (p. Just as childhood developmental stages (art) paralleled Piaget’s cognitive theories (see Chapter 2), the results of Alter-Muri’s study found that Lowenfeld’s methods were applicable across cultures in Europe. Unfortunately, the research inherent in a qualitative breakdown of a pro- jective test is often based upon Western criteria. For that reason, when tak- ing cultural variations into account "projective techniques are found use- ful when the researcher is investigating a specific hypothesis, using an objective system of scoring" (Al-Issa, 1970, p. I chose the HTP projective test for its previously noted ability to measure independently quantitative details and for its objective scoring system. However, I must state that Buck’s study (not unlike Lowenfeld’s) focuses on research developed by Western participants and standards.

First, social support shows robust direct Syme pioneered the notion that social relationships effects on health outcomes. Third, support from friends is more produced stress on ulcers, hypertension, and neurosis in strongly related to health outcomes than family support. In addition, it was shown to reduce It is hypothesized that the voluntary nature of friend anxiety and physical arousal (via secretion of fatty acids) support may increase quality. Physical contact and the presence of others more likely to offer mutually appealing support. Handling that link social relationships to health, clinicians should reduced the arteriosclerotic impact of high-fat diets in proceed by recognizing the importance of their patients’ rats. Bovard proposed a psychophysiologic theory sug- social integration and support and assess it as part of a gesting social relationships, mediated through the amyg- normal social history. One may ask what kinds of organ- dala, activated the anterior hypothalmic zone and, hence, izations and activities are important to the patient. A secretion of adrenocorticotropic hormone, cortisol, comprehensive assessment of a patient’s level of social catecholamines, and associated sympathetic autonomic support should include questions regarding amount, fre- activity. Gathering such information Similar to socioeconomic status, links between social does not require the physician to resolve support issues. Researchers in this in which medications or other health regimens are pre- tradition have focused particularly on the effects of two scribed. If recommending dietary adjustments, increased types of connectedness: social integration (i. It also is ering from illness or medical intervention, providers associated with increased likelihood of recovery from should assess the nature of support that is in place. Perhaps most importantly, physicians should ascertain Religious participation is the dimension most strongly the extent to which their patients "feel" supported. For example, One important form of social integration involves the Mormons, Seventh Day Adventists, and members spiritual involvement and religious participation of older of other religions with strict behavioral prohibitions patients. In recent years, the medical community has around health, on average, are healthier and live longer. When patients social support and thereby be associated with im- refer to their faith or spirituality, there are at least three proved health outcomes.
