cotnruction workers and seniors
sport injuries causing SCI are only from competitive sports
false, also recoretional
which sport is number 1 for for SCI
diving (pool and lake)
what is the link between SCI and olfactory bulb
ttthe neurons in the olf bulb can be regenerated ad used to jelp people with spinal cord injuries to repair and regroq
where do they inject cells from olf bulb in SCI and why
in the lesion and to reconnnect connections with neurons in the spine
how mant new cases per year of SCI
1100 new cases per year and
how many canandians are living with the impacts of SCI
44,000 Canadians
now living with the impacts of a SCI
what are the annual health care costs
3.6 bil
what are the lfietime care costs per person for SCI
1.6-3 mil
why is the range per personn in costs for SCI so large
the cost deoends on the severity and the age
how is more likely to suffer from SCI females or males and what percentage)
males (80%)
about 80% of SCI are males and in the age range of BLANK
16-30
about 80% of SCI are males and in the age range of 16-30… why
because of work, theyre more impulsive,, risk takers
true or false: lesions can only be complete
false can also be imcomplete
what is the percentage of complete vs incomplete SCI
50-50
in the past was there more complete or incomplete lisions
complete
why is there a decrease in complete lesions now vs in the past
meds, car sagetly belt and airbags, paramedics (for spinal immobilization)
what are meds used for in SCI
controlloing inflamation
are sensations above the lesion still intact
yes
sensory info comes from what pathways
asceding tracts. dorsal tracts
cutaneous info and proprioceptive are part of what system
somatosensory cortex
motor commands come down through what pathways
decsending (vental tracta0
Can an individual with a spinal
cord lesion at the lumbar level
contract his arm muscles?
yes
why Can an individual with a spinal
cord lesion at the lumbar level
contract his arm muscles?
because arms are cervical and trunk is thoractic but only legs are lumbar
what does the severity of the condition depend on sci
the level of the lesion
whether it is complete or incomplette
true or false, the injury can only affect one vertebra
false, more than one
quadriplegia is the involvmend of what parts of the body
all 4 limbs and trunk
what is the cause of quadriplegia
damage to the cervical sengments
what is the most common place of lesion in quadriplegia
c5-c6
why is c5 c6 the most common place of lesion in quadriplegia
because that is the most common in car accidents
c7 limits what motion
elbow extension
why is elbow extension important for wheelchair users
triceps innervation
paraplegia is the involvment of what body parts
lower limbs and/or trunk
true or false: the trunk is always involved in paraplegia and why
false, it depends where the damages are made
what is the cause of paraplegia
damage to the thoractice of limbar spine
true or false, an injury at the limbar does not affect the trunk
true
if you get a complete lision from t1-t6, what does taht affect
no sitting balance
if you get a complete lision from t7-l1, what does taht affect for sitting
you can do some useful sitting
if you have a complete lesion from l2 or lower do you have abnormal or mormal trunk ccontrol
normal trunk cometrol
what are the 6 health concerns in SCI
1) sensation loss
2) contractures and injury preventatino (spasticity)
3) lower limb atrophy
4) osteoporosis
5) weight management
6) ANS dysfunction during exercise
if you have a complete lesion you you have total or partial loss
total loss below lesion
if you have an incomplete lesion you have total or partial loss
partial loss below lesion
if you have an incomplete lesion you loss all types of sensations?
false, you may not lose some but not others
with a incomplete lesion are you more or less vulnerable to an injury
more
what does contractures and spasiticity mean
shortening and tightning of mhscles
where are the most common places for spasticity and coontractiures in SCI
flexors in upper limbs
extension on lower limbs
what can help prevent contractures and spasiticty for SCI
stretching 2x day (full ROM)
what is a common upper body position for SCI i
triple flexion
what is a common lower body position for SCI
platar flex and ankle inversion
what extrinsic method can you use to help with contracyture and spasticity
dorsal hand splint
why is lower limb atrophy, osteroporosis and weight management very common in wheelchair users (3)
b
because of a decrease in
1) muscle contraction (paralyssis)
2) mechanical loading on bones
3) energy expenditure
