the three systems that interact to cause pain
sensory/discriminative
motivational/affective
cognitive/evaluative
sensory/discriminative system
how process intensity and strength of pain
motivational/affective system
conditioned or learned approach to pain. based on personal experiences and cultural influences
any avoidance behaviors of pain are part of the:
motivational/affective system
cognitive/evaluative system
spiritual, cultural, experience and other influences on how to react to pain
somatogenic pain
has a known cause
psychogenic pain
unknown cause
acute pain is a ___ for the body
protection mechanism
three types of acute pain
somatic, visceral, referred
somatic acute pain
pain of the muscle, bone, skin
visceral acute pain
pain of an organ. radiates. causes N/V
referred acute pain
area of pain is different from origin of injury.
referred pain should be:
taken seriously
chronic pain
lasts more than 6 months
Chronic pain can be either ___ or ___ and can be classified as either ___ or ___ pain.
constant or intermittent
central or neuropathic
Central chronic pain
lesion or disruption in CNS
Neuropathic chronic pain
trauma or disease in peripheral nerves
Chronic pain causes:
behavioral changes, depression, sleeping, eating, anger
the goal when dealing with chronic pain
to get patient back to normal function. Can't always eliminate pain
eight chronic pain terms to know
neuralgia, causalgia, reflex sympathetic dystrophies, hyperesthesias, myofascial pain syndrome, hemiagnosia, phantom limb, trigger points
neuralgia
damaged peripheral nerve
nerualgia is usually caused by
acute trauma
causalgia occurs
a couple of weeks after injury.
causalgia affects
groups of nerves and causes discoloration of skin
hyperesthesias
increased sensitivity and decreased pain threshold to tactile and painful stimuli.
hyperesthesias may result from
chronic irritations of CNS areas
because of hyperesthesias
pain is diffuse (becoming widely spread), modified by fatigue and emotion and mixed with other sensations
myofascial pain syndromes are the
second most common chronic pain condition
myofascial pain syndromes
pain results from muscle spasm, tenderness, and stiffness
examples of myofascial pain syndromes
myostisis, fibrositis, myofibrositis, myalgia, and muscle strain--conditions that involve injury to the muscle and fascia
myofascial pain syndromes cause
decreased use in area
hemiagnosia are associated with
stroke
hemaignosia
loss of ability to identify the source of pain on one side of the body
painful stimuli on the side of the body with hemignosia produce
discomfort, anxiety, moaning, agitation, and distress but no attempt to withdraw from the stimulus
a person who has hemaignosia knows pain sensation but
cannot determine where it is coming from
phantom limb pain
pain in limb that has been amputated after it has completley healed
trigger points
small hypersensitive regions in muscle or connective tissues that, when stimulated, poduce pain in a specific area
pain threshold and pain tolerance are used to
assess pain
pain threshold
point at which person perceives pain
pain tolerance
amount tolerated until doing something about it
example of referred pain
bowel rupture which causes air to travel to subscapula and cause pain under shoulder
pain receptors are located on the ___ side of neuron
afferent (sensory)
pain receptors are found in
the skin, mucous membranes, lining of body cavities, and deep tissue (everywhere)
when people with hyperesthesias recieve a light touch
it elicits acute pain
reflex sympathetic dystrophies
damage to peripheral nerve that causes severe burning senesation in innervation area
