It is forced into the venous end of the capillary bed when the net hydrostatic pressure is less than oncotic pressure.
True
- no tight jxns in capillaryies
- anchoring filaments attach capillaries to fascia (keep capillaries open when interstitial pressure inc.)
- valves ensure unidirectional flow
- lymph hearts between valves: cyclically contract - lumph pumps
Lymphatics: Which of the following is correct about lymph fluid?
a. lymph formation creates pressure gradients that drive lymph movement through lymphatic vessels
b. lymphatic vessels drain fluid from the tissue and and continuously provide information about the tissue to the immune system
c. lymph vessels transport microbial antigens, tissue antigens, toxins, cytokines, apoptotic cells from tissue to regional lymph nodes
all of the above
Lymphatics: Failure of the lymphatic system has been implicated in the pathogenesisof cardiovascular disease, infection, intestinal disease, autoimmunity, inflammation and edema.
True/False - Interventions that improve lymph flow may relieve edema and treat infection by enhancing the circulation of immune cells, inflammatory mediators and pharmaceuticals
True
Lymphatics: Physical therapy has been shown to increase lymph flow in humans and animals. Examples of PT include:

Lymphatics: Dogs were surgically instrumented to measure thoracic duct lymph flow. Results showed increased lymphatic flow, however, which of the treatments provided the greatest increase in lymphatic flow?
The greatest increases were seen during abdominal pump and exercise
Lymphatics: The lymph nodes act as the site of antigen processing. They circulate up to 40x/day.
True/False - It is believed that OMT may redistribute lymph pools, thereby enhancing lymph flow and immune surveillance. LPT helps to mobilize lymph-borne factors and pharmaceuticals (that protect against infectious and inflammatory diseases) into circulation.
True
Lymphatics: Who helped quantify the amount of lymph that can be pumped?
Norman Gevitz
Lymphatic: In Dr. Hodge’s experiment, lymph flow was measured with their patients (dogs) under anesthesia. They collected the lymph and measured the flow during baseline, during 4 min abdominal LPT and post-LPT. The concentration of protein, leukocytes, cytokines, chemokines, and ROS were measured and comparisons were made between the timepoints.
What was found?
- 1st 4 minutes: baseline steady
- Within 1 minute LPT: inc. leukocytes, remains elevated through LPT
- At 8 minutes: LPT was stopped leukocyte concentration returned to baseline
**significant, transient increase in lymph articulation; not significant change in MAP
Lymphatic: During administration of LPT, leukocyte flux was increased in the lymph.
True/False - All cells were increased including B cells with different isotypes (IgA and IgG). After 4 minutes of LPT 10 fold cells were found in the circulation. Furthermore, memory and effector cells were present
True
Chronic pain: The biomechanical model involves the musculoskeletal system (postural muscles, spine and extremities).
It is responsible for posture and motion of the body in space. In cases of dysfunction, OMM can be used to re-establish normal function. What are examples?
Foot orthotics (improve posture - dropped arches, leg length inequality)
*consider meds and surgery as indicated
Chronic pain: The respiratory model is associated with the thoracic inlet, thoracic and pelvic diaphragms and the rib cage. It affects mechanics of repiration, circulation and lymphatic drainage.
Emphasis is on unimpeded delivery of oxygen and nutrients as well as removal of waste products. If these things do not happen, tissue health will be affected (impact other systems). What are OMT therapies?
- decrease somatic dysfunction in fascia, muscle, tissues associated with respiration, circulation, and lymph
- meds/surgery as indicated
Chronic pain: The neurological model is associated with the CNS, PNS, ANS and viscerosomatics. It is responsible for the coordincation and integration of body functions as well as maintenance of homeostasis. It also addresses the neurologic aspects of pain.
True/False - OMM in this model helps to normalize neural function such as treating a viscerosomatic reflex or treating the OA (incerase PNS and decrease SNS; relaxing).
True
*consider meds/surgery as indicated
Chronic pain: The metabolic-energetic model is associated with viscera and endocrine glands and diet (processed foods inc. inflammation and pain). It functions in the maintenance of homeostasis (most function = least amount of energy).

removes somatic dysfunction
*consider meds/surgery
Chronic pain: The behavioral model evaluates mental, emotional and spiritual states and lifestyle choices.
True/False - The musculoskeletal system and emotional states can reflect each other. This is where OMM can help.
True
*consider patient education/medications
Chronic pain: Pain is a complex process that involves afferent input from the body and is modulated through the spinal cord, limbic system and cerebral cortex.
True/False - Pain is subjective. It is considered chronic if it lasts longer than 12 weeks. It is possible for patients to consciously affect their experience of pain through the cerebral cortex. If this happens, chronic pain becomes a biopsychosocial problem in addition to physical.
True
types:
- -acute/chronic
- -malignant/non
- -nociceptor induced (musculoskeletal/visveral)
- -neuropathic, referred or SNS maintained (reflex sympathetic dystrophy, chronic regional pain syndrome
Chronic pain: True/False - Different medications target different aspects of pain (NSAIDS target inflammation, gabapentin targets neuropathic pain)
True
*see article about chronic pain meds
Chronic pain: Regional pain (not in dermatome or other distribution) that is associated with changes in sensation (e.g. allodynia), motor, autonomic (sweating, vasomotor) and/or skin changes. It is most often in the distal limb.
It presents as two types.

What are the two types of chronic regional pain syndrome?
- Type I “regional sympathetic dystrophy”
- -90%
- -no peripheral nerve damage - Type II CRPS
- -peripheral nerve damage *
Chronic pain: True/False: Regional Pain (Chronic regional pain syndrome) is similar to fibromyalgia in that it is thought to be secondary to central sensitization. Initial injury could cause hypersympathetic stimulation and facilitation of the area.
It tends to develop 4-6 weeks after the initial injury (fracture, crush, sprain, surgery) and usually requires multidisciplinary team approach to treat successfully.
True
Chronic Pain: The most successful approach to treating chronic pain is multi-disciplinary (treat physical symptoms and experience of pain) due to the fact that it has interdependent psychosocial and physical elements.
What are the aspects of the biopsychosocial model associated with chronic pain?
- Psychological
- -how patient represents pain to self
- -“I am disabled” - Social
- -how patient presents pain to others OR influences of social cues on a person’t behavior
- -“other people need to help me”
*does patient have secondary gain (attention from others or others doing their chores?
Chronic pain: Multi-disciplinary teams can involve physicians (PCP, pain management, psychiatrists), psychologists, PT/OT’s, dieticians and medical social workers. There is a wide variety of approaches to the problem which has multiple roots.
True/False - Studies have shown this approach leads to decreased experience of pain, decreased functioning, and lower rate of return to work.
False
- decreased pain, increased functioning, inc. return to work
- psychological effects: decrease catastrophizing, self reported disability and depression

You decided to perform a bicycle test to differentiate between vascular and neurogenic claudication because you suspect ______
Spinal stenosis
- may have vascular and neurogenic at the same time
- vascular: walking, doesn’t improve w/ forward bending
- if secondary to nerve impingement: objective weakness, atrophy and asymmetric weakness

HVLA: What should be performed prior to HVLA?
Soft tissue
- dec. hypertonicity
- inc. resiliency of tissues around dysfxn
- relax/reassure patient
- less force needed w/ relaxed muscles/tissues
HVLA: Because HVLA techniques function to gap the joint (stuck drawer), the operator must be well versed in the anatomy.
True/False - An audible “pop” may coincide with joint gapping, however, production of a pop is NOT the therapeutic goal
True
HVLA: The following are the basic principle of HVLA -
- Accurate diagnosis
- Choice of vectoring force
- Engage the restrictive barriers
- Do NOT back off the stacked barrier before you thrust (balance and control)

- Rotational (cervical, lumbar)
- Tranlatory (cervial, thoracic)
- Distraction (added dimension to all areas)
HVLA:
- ______ lever: when the force vector is applied directly at the bony landmark as the focal point (cervical, ribs, thoracic spine)
- ____lever: when the force vector is directed from a distance to the dysfunction utilizing traction forces through myofascial components (lumbars)
- Short lever
- Long lever
*methods of thrust: direct **
HVLA: There are several different theories/hypotheses that explain the mechanism of HVLA. Of the following, which is the most current hypoothesis?
- Thrust forcefully stretches a contracted muscle producing afferent impulses from the muscle spindles to the CNS. CNS reflexively sends inhibitory impulses to the muscle spindle to relax the muscle.
- The thrust forcefully stretches the contracted muscle pulling on its tendon, activating golgi tendon receptors and reflexively relaxing the muscle.
- Thrust produces a cavitation effect in the joint. Sudden distraction of joint surfaces produces a nitrogen bubble, along with the noise and increased freedom of motion.
