chap 3 Pain tone and motion Flashcards
- “an experience based on a complex interaction of physical and psychological processes.”
- An unpleasant sensory and emotional experience
- Associated with actual or potential tissue damage
- Can be a warning sign
- Most common symptom prompting patients to seek medical attention
pain
pain that is Less than 6 months duration
Acute pain
pain that Persists beyond the normal time for tissue healing-
chronic
The experience of pain in one area when the actual or potential tissue damage is in another area
Referred pain
And what technique can we utilize to determine location of pain?
palpation
this pain Activates sympathetic nervous system
acute pain
Caused by the stimulation of pain receptors by noxious mechanical, chemical or thermal stimuli and associated with ongoing tissue damage
Nocioceptive pain
Result of peripheral or CNS dysfunction without ongoing tissue damage
Neuropathic pain
Psychological and social factors associated with chronic pain:
Depression Catastrophizing Decreased function Decreased ability to maintain employment Increased dependence
this pain is felt at a location distant from its source.
May be referred from one joint to another
Peripheral nerve to a distal area of innervation
Internal organ to an area of musculoskeletal tissue
Referred Pain
It is proposed that pain is referred in one of three (3)ways: what are they
From a nerve to its area of innervation
From one area to another derived from the same dermatome
From one area to another derived from the same embryonic segment
specific nerve endings called nociceptors respond to all painful stimuli, and specific nerve types transmit the sensation of pain from these nerve endings to the spinal cord and then within specific tracts, to the brain. What are these fibers called?
- myelinated A-delta fibers
- unmyelinated C fibers
Large, myelinated axons that conduct impulses more quickly than A-delta and C fibers
Located in the skin, bones and joints
Normally, transmit sensation related to vibration, stretching of skin and mechanoreception
A-Beta Fibers
- Group III afferents
- Transmit more rapidly
- Most sensitive to high intensity mechanical stimulation
- Sensations described as sharp, stabbing, or pricking
- Generally, not blocked by opiates
A-Delta Fibers
Sharp, pricking or tingling
Cutaneous pain
