Chapter 10: Domain IV: Therapeutic Intervention
You are working with a patient with acute back pain and researching the efficacy of various interventions. You review a study on the use of acute lumbopelvic manipulation to relieve acute low back pain. The reference article has a Level II validation. What does this imply about this treatment intervention?
A. The study is prospective in nature using a variety of patients and clinicians to evaluate impact on clinical practice. Clinicians can use the results in a variety of settings with confidence that it will improve patient outcomes.
B. The study is prospective in nature with a variety of patients and clinicians, and the intervention can be used with confidence in a variety of settings.
C. The study is prospective in nature and uses similar patients and clinicians. The results are best used in settings similar to those in the research.
D. The study is retrospective in nature or is a new original research project. The results should not be used exclusively until further validation can be conducted.
B: Clinical prediction rules for diagnosis, intervention, and prognosis can be validated using a four-level (I to IV) validation scale with a level I clinical prediction rule being most predictive and level IV requiring additional validation.40 Question Level: AN
An athlete has sustained a hamstring strain. Which of the following physiological events indicates the fibroblastic repair phase of the healing process for this injury?
A. Immediate vasoconstriction followed by reflex vasodilation, stagnation, and stasis
B. Formation of an insoluble fibrin clot and phagocytosis
C. Synthesis of intracellular matrix and formation of granulation tissue
D. Formation of fibroblasts, decrease in type III collagen fiber, and increase in type I collagen fibers
E. Conversion of prothrombin to thrombin and production of collagen fibers
C: The fibroblastic repair phase is marked by proliferation and regeneration that allows for scar tissue formation. The fibroblastic repair phase follows the inflammatory response phase and begins by stimulating the growth of endothelial capillary buds to increase oxygen delivery to the injured site. Then the granulation tissue is deposited to fill the gaps of the fibrin clot as it breaks down.30 Question Level: R
Which of the following physiological responses is most associated with the inflammatory phase of the healing process?
A. Histamines are released from the leukocytes causing vasodilation and decreased ...
