What is phantom pain?
although the limb isn't there, the nerve endings at the site of the amputation continue to send pain signals to the brain that make the brain think the limb is still there
When dealing with phantom pain, is it true that sometimes the brain memory of pain is retained and interpreted as pain regardless of signals from injured nerves?
Where does the pain originate when dealing with phantom pain?
in the cut ends of the primary afferent fibers near the surface of the stump
What is referred pain?
pain originating from a site on/in the body but felt in other areas

pain that persists after a wound has healed
pain that extends beyond the normal course of injury or illness or amount of pain perceived is much greater
In what can chronic pain be produced?
(1) the PNS at the site of the injured nerves
(2) the CNS by neural patholgies that are largely unknown

the level of noxious stimulus required to alert an individual to a potential threat to tissue
What are trigger points?
pathological localized areas of pain that are hypersensitive to stimulation
Where can trigger points be found?
other soft tissue such as ligament, tendon, & fascia
What are dermatones?
a segmental skin area supplied by a single nerve root
What is a placebo effect?
pain reduction obtained thru mechanisms other than those related to the physiological effects of the treatment
if the pt thinks the treatment is beneficial than a degree of pain reduction occurs
How might a PTA use the placebo effect for the good of their pt?
mind over matter
PTA can use thise with theraputic modalities by changing modalities and new approaches in the treatment of an injury
can have a positive influence on the pt's perception and result in decreased pain
Why do gender differences in regard to pain preception matter to the PTA?
extroverts will quickly tell you how much pain they are in but introverts won't
Do male or female patients describe more pain and are more vocal about it?
Do women or men receive more and stronger pain medications?
Are men or women less likely to receive no medication for their pain?
How do you know if a nerve tract is an efferent or afferent tract?
afferent not strong enough to produce sufficient stimulus to open the gatemotor response
Do efferent or afferent pathways lead to the cortex receiving sensory information at 4 different levels all the way up?
Do efferent or afferent pathways lead away with actions occuring at the highest level?
Which nerve tract controls the sensory flight or fight limbic?
What is an ecchomosis?
blue/black discoloration of the skin caused by movement of blood into the tissues
In the later stages of ecchomosis, what colors may appear?
greenish brown or yellow
What is a hematoma?
a mass of blood confined to a limited area resulting from the subcutaneous leakage of blood
What is neuropathy?
destruction, trauma, or inhibition of a nerve
How long does the early phase of inflammation generally last?
a few seconds to a few months
Martha - 0-14 days
What is General Adaptation Syndrome?
a theory stating that the body has a common mechanism for adapting to stress
What happens in the alarm phase of GAS?
vessels constrict in extremities to supply more blood to the heart (fight or flight) to prevent any change in homeostasis
What happens in the resistive phase of GAS?
individual achieves physiological resistance or physical fitness working to maintain homeostasis plateau in the body's adaptation to stress
works to maintain homeostasis chornic inflammation
How long does the restrictive phase of GAS last?
many months to years
What happens in the exhaustion phase of GAS?
the body can no longer withstand the applied stresses
at this point 1 or more body systems can't tolderate the stress and therefore fails
point of distress-negative effect
traumatic or overuse injuries - no longer tolerant of stresses
elimination of homeostasis

What is the Gate Pain Theory?
suggests that the spinal cord contains a neurological gate that either blocks pain signals or allows them to continue on to the brain
How does the gate in the spinal cord operate according to the Gate Pain Theory?
by differentiating b/t the types of fibers carrying pain signals
