Test #1 Flashcards
What are the steps of General Adaptation Theory?
Alarm
Resistance
Exhaustion
Alarm
“fight or flight”
initial response to injury/stress
Resistance
adaptation to stress
plateau
ex. muscle guarding
Exhaustion
body can no longer withstand stress = it gives out
longest stage
leads to overuse injuries
Adipose tissue is a good medium for what modality?
ultrasound
Cardinal Signs of Inflammation
redness
swelling
heat
pain
loss of function
Acute Inflammatory Response Cells
neutrophils
histamines
herparin
prostaglandins
kinins
Heparin
anticoagulant
Prostaglandins
increase capillary permeability
stimulate free nerve endings
Kinins
produce pain
Edema
old swelling that just pools or sits somewhere
What are the dimensions of pain perception?
sensory discriminative
cognitive evaluative
affective motivational
Sensory discriminative
localizes source of pain
Cognitive evaluative
interprets pain based on past experiences and expectations
Affective motivational
limbic system causes inward and outward responses (fear, anxiety, crying)
Afferent
body to brain
Efferent
brain to body
Which component of pain perception can be affected by modalities such as cold application?
Pain tolerance
What are the superficial receptors?
Thermal receptors
Merkel’s discs
Meissner’s corpuscles
Pacinian corpuscles
Ruffini corpuscles
Nociceptors
Merkel’s discs
react to low threshold mechanical pressure
adapt slowly
Meissner’s corpuscles
react to low threshold mechanical pressure
adapt rapidly
Pacinian corpuscles
deep in skin
react to HIGH levels of mechanical pressure
Ruffini corpuscles
stretching of skin and changes in joint position (proprioceptive)
Pain control theory targets what?
perception of pain
Gate control theory
distract from pain sensations with another sensation
Gate control theory -ascending
A-beta = muscles
small diameter traffic = pain stimuli
To decrease nociceptive stimuli:
- stimulate A-beta = closing small diameter traffic
Gate control theory -descending
gate closes in ascending and opioids are released to control pain perception
Electrical stimulation does what?
overloads the senses
Local anesthetics
cause loss of sensation in the area (ex. biofreeze)
What is the highest level of regulation?
licensure
Certification =
do you know what you are supposed to know
Registration
register with state before practicing
Blanket prescription
assigned to no one
