Secondary injuries are essentially the inflammatory response that occurs with the primary injury.Microtraumatic injuries occur as a result of a cumulative repetitive overload, incorrect mechanics, and/or frictional resistance. Macrotraumatic injuries occur with a sudden overloading of the musculoskeletal tissues.(1) Coagulation and inflammation stage. (2) Migratory and proliferative stage. (3) Remodeling stage.Neutrophils are white blood cells of the polymorphonuclear (PMN) leukocyte subgroup that appear during the inflammation stage. Neutrophils are filled with granules of toxic chemicals (phagocytes) that enable them to bind to microorganisms, internalize them, and kill them.Monocytes are white blood cells of the mononuclear leukocyte subgroup. The monocytes migrate into tissues and develop into macrophages, and provide immunological defenses against many infectious organisms. + Chapter 3 Download Section PDF Listen ++ EAAAC + Chapter 4 Download Section PDF Listen ++ Empathy is the ability to see another person's viewpoint so that a deep and true understanding of what the person is experiencing can be made.An examination refers to the gathering of data and information concerning a topic.

The hamstrings are frequently shortened in this syndrome.Any five of the following: age, strength and flexibility imbalances, psychological aspects, evolutionary and hereditary influences, structural deformities, disease, pregnancy, habit, or pain.Postural muscles—Relatively strong muscles that are likely to be poorly recruited, lax in appearance, show an inability to perform inner range contractions over time, or provide a stable base for other muscles to work from.Phasic muscles—These muscles tend to become relatively weak compared to the postural muscles and are more prone to atrophy and adaptive shortening and show preferential recruitment in synergistic activities. In addition, these muscles will tend to dominate movements and may alter posture by restricting movement. + Chapter 7 Download Section PDF Listen ++ Plain radiographs.The following structures are listed in order of descending density: metal, bone, soft tissue, water or body fluid, fat, and air.Plain-film, or conventional, radiographs.Ligamentous injuries, joint instabilities.Magnetic resonance imaging (MRI).Arthrography.Angiography.Spatial resolution and contrast resolution. + Chapter 8 Download Section PDF Listen ++ Coordination, communication, and documentation; patient/client-related instruction; and direct interventions.PRICEMEM (Protection, Rest, Ice, Compression, Elevation, Manual therapy, Early motion, and Medications).Stimulation of the large fiber joint afferents of the joint capsule, soft tissue, and joint cartilage, which aids in pain reduction; stimulation of endorphins, which aids in pain reduction; a decrease of intra-articular pressure, which aids in pain reduction; the mechanical effect which increases joint mobility; the remodeling of local connective tissue; the increase of the gliding of tendons within their sheaths; and an increase in joint lubrication.The inflammatory stage of healing.The clinical aims during the inflammatory phase are to avoid painful positions, improve range of motion, reduce muscle atrophy through gentle isometric muscle setting, and to maintain aerobic fitness. + Chapter 9 Download Section PDF Listen ++ Pharmacokinetics is the study of the physicochemical factors involved as the body absorbs, distributes, metabolizes, and eliminates a drug. Pharmacodynamics refers to the effect the drug has on the body.The part of the autonomic system (sympathetic or parasympathetic) that is in control at rest is said to exert predominant tone.Water-soluble vitamins include the B complex, vitamin C, biotin, choline, and folacin (folic acid).Liver and kidneys.Exercise increases muscular blood flow and temperature and thus can enhance absorption through molecular diffusion across biological membranes. Exercise may also sequester some drugs and reduce the availability of the drug for elimination. Thermal agents that increase regional blood flow can potentially increase delivery of a drug to a specific tissue site. Theoretically, cold can restrict drug delivery by causing vasoconstriction at the cryotherapy site. + Chapter 10 Download Section PDF Listen ++ When there is mild pain; a nonirritable condition demonstrated by pain that is provoked by motion but which disappears very quickly; intermittent musculoskeletal pain; the pain reported by the patient is either relieved by rest or by particular motions or positions; and the pain is altered by postural changes or movement.Any five from the following: bacterial infection, malignancy, systemic localized infection, sutures, recent fracture, cellulitis, febrile state, hematoma, an acute circulatory condition, an open wound, osteomyelitis, advanced diabetes, hypersensitivity of the skin, and constant severe pain.Traumatic hyperemia, pain relief, and decreasing scar tissue.Strain–counterstrain, or functional techniques.Joint mobilizations. + Chapter 11 Download Section PDF Listen ++ Posture, direct trauma, extremes of motion, electrical injury, and compression.Double-crush syndrome.Visible atrophy, pain with palpation, diminished active and passive range of motion in the same direction, and weakness in the muscle distribution of a peripheral nerve.L4–S2.30–70 degrees. + Chapter 12 Download Section PDF Listen ++ Extensibility, elasticity, irritability, and the ability to develop tension.The erector spinae, the biceps brachii, the long head of the triceps brachii, the hamstrings, and the rectus femoris.Isometric, concentric, and eccentric.An isotonic contraction is a contraction in which the tension within the muscle remains constant as the muscle shortens or lengthens.True. + Chapter 16 Download Section PDF Listen ++ External rotation > abduction > internal rotation in a 3:2:1 ratio.DSubscapularis, teres major, pectoralis major, and latissimus dorsi.Infraspinatus, teres minor, and posterior deltoid.Supraspinatus, infraspinatus, teres minor, and pectoralis major. + Chapter 17 Download Section PDF Listen ++ False.

In this variation, the artery runs vertically and slightly medial and posterior to reach the transverse foramen of the lower cervical spine, although its exact direction is dependent on its exact point of origin (any anomalies result in tortuosity). The typical point of entry is at the C6 transverse foramen, but 10% of the population has entry points from C5 to C7. Also, the postsubclavian artery could have a kink in it.Divided into four parts: (1) Within the transverse foramen of C2. The C2 vertebral foramen has two curves: the inferior curve is almost vertical, whereas the superior curve is more horizontal and orientated laterally. (2) Between C2 and C1. The second part runs vertically upward in the transverse foramen of C2 and is covered by the levator scapulae and the inferior capitis muscles. (3) In the transverse foramen of C1. In the third part, the suboccipital portion of the vertebral artery bends backward and medially in the transverse foramen of C1. (4) Between the posterior arch of the atlas and its entry into the foramen magnum. On exiting the transverse foramen of C1, the artery travels behind the mass of the superior articular process of the atlas to cross the posterior arch of the atlas in a groove in which it is held by a restraining ligament. From the medial end of this groove, the artery runs forward, inward, and upward to pierce the posterior atlanto-occipital membrane with the nerve of C1 which separates it from the posterior arch of the atlas. It penetrates the dural matter on the lateral aspect of the foramen magnum, about 1.5 cm lateral to the midline of the neck. The artery is vulnerable to direct blunt trauma in this portion.(1) Pontine branches—pons. (2) Anterior inferior cerebellar artery—pons and cerebellum. (3) Superior cerebellar artery—pons midbrain and cerebellum. (4) Internal auditory (labyrinthine)—membranous labyrinth and eighth cranial nerve (vestibulocochlear).
