Chronic Pain
IASP
definition
“an unpleasant sensory or emotional
response to a stimulus associated with actual
or potential tissue damage”
Pain “lasting longer than the anticipated
course of recovery” – often 3-6 months
Neurologic, physiologic, and emotional
components ( suffering)
Nociceptive Pain
Noxious
stimuli activating peripheral
receptors producing typical acute pain
along a-delta and C fibers
Pin-prick or stab wound or stubbed toe
Burn injury
Fractures
Neuropathic Pain
Pain
associated with injury or disease of
peripheral nerves
DM peripheral neuropathy
Shingles ( PHN)
Radiculopathy
Burning, shooting, lancinating pain
Allodynia, hyperpathia, central sensitization

Conservative
management of pain
after TBI
Rachel Heberling, MD
Cincinnati VA Medical Center
University of Cincinnati
Why Conservative Pain
Management in TBI?
Increased
sensitivity to medications
Increased difficulty managing medications,
especially prn’s
Increased self-efficacy via selfmanagement
Potentially decreased number of office
visits
Cost-effective
Heat
Superficial
heat: heating pad, hot shower,
hot bath
Deep heat: ultrasound
Effective
for pain relief, increased muscle
flexibility
Not much evidence, but obviously effective
briefly
Cold
Superficial:
Ice packs
Deep: cold laser
Cold
effective for pain relief and reducing
inflammation, but contracts muscles
Unclear mechanism and efficacy of cold
laser
STRETCHING!
Muscle
has viscoelastic properties
Slow, deep stretch paired with deep
breathing necessary
Muscle properties change for ~10 hrs after
deep stretch
Evidence
not compelling, but pain-relief
effect of stretching is very obvious
clinically
Stretching!
Other types of Exercise
exercise – has huge role in
decreasing muscle tension and
consequent pain.
Strength training – some role in
decreasing pain (e.g. core strengthening),
but generally minimized until pain
beginning to improve.
Aerobic
Meditation
Increasing
base of evidence for the pain
relief effects of meditation
Decreases stress
Improved emotional acceptance of pain
Yoga
EXCELLENT
choice for exercise
maintenance
Has role in decreasing active pain issues
as well.
Must start in beginner class!
Advanced Yoga Class
Tai Chi
Becoming
more popular topic of research
Have found that Tai Chi practice
decreases falls in the elderly
Somewhat similar to yoga, but more
focused on gentle fluid movement, as
opposed to deep prolonged stretch

sessions over 10 weeks regardless of
group
5 additional sessions for partial
responders (>10%, <50% improvement)
Limited communication with acupuncturist
