ongoing and not severe, but little to no recovery of function even with treatment
define an episodic physical disability
recurs but normal functioning most of the time
define a progressive physical disability
worsens over time
what is the prevalance rate of PD
more students today with PD than 30 years ago; due to improvements in medical treatments and tech to save lives with leads to more newborns who have severe health/physical injury and/or disability
what is Neuromotor Impairment

a type of physical disability in which defects or diseases of the muscles/bones that cause difficulty walking, standng, sitting, or using hands
what is Muscular Dystrophy? (MD)
a type of muscular dystrophy PD
degenerative, hereditary disease causing a progressive weakening of the muscle tissues
what are two examples of Muscular Dystrophy?
- Duchenne MD
- Facioscapulohemeral
what is Duchenne MD? (PD)
causes muscle weakness that starts in the pelvis and thighs and spreads to arms legs and trunk
what are some details of Duchenne MD (PD)?
mainly affects boys, usually age 3-5
most can no longer walk by 10-12
can cause problems in breathing/heart
most die in late teens/early 20s
what causes Duchenne MD? (PD)
a gene mutation that affects the production of a protein called dystrophin
linked to X-chromosome
what is facioscapulohumeral MD? (PD)
a genetic muscle disorder in which the muscles of the face, shoulder blades, and upper arms are effected
what are some details of facioscapulohumeral MD?
typically appears in teens of either gender
develops slowly (facial movements)
normal lifespan
what is the cause of facioscapulohumeral MD?
pieces of a gene called DUX4 are abnormally activated in FSHD-affected cells leading to the production of toxic proteins
CAUSED BY GENES
what are some other examples of Physical Disabilites?
severe asthma
AIDS
diabetes
cystic fibrosis
juvenile rheumatoid arthritis (JRA)
define a Traumatic Brain Injury (TBI)
an insult to the brain, not degenerative or congenital, but caused by an external, physical force that may produce diminished or altered state of consciousness, which can result in an impairment of cognitive abilities and/or physical functioning
what can a TBI also effect?
the disturbance of behavioural or emotional functioning
how is the a TBI measured?
levels of severity measured by altered state of consciousness using a Glasgow Coma Scale
what are the 3 levels of severity of a TBI
- Mild TBI (score of 13-15 on GCS)
- Moderate TBI (score of 9-12 on GCS)
- Severe TBI (score of 8 or less on GCS)
the impact of a TBI on a child depends on:
- the site of the trauma (frontal vs temporal lobe)
- the age of the child (stage of brains development)
- other co-occuring injuries/health concerns
what are some causes of a TBI?

- a direct blow to the head
- a rapid acceleration and deceleration of the head
what is the highest cause of TBI’s?
transportation
what is the prevalence rate of TBI’s
varies; hard to measure accurately due to effects changing over time)

more males than females
what are some difficulties experienced post-TBI
remembering
speech/language
irritability
aggression
mood swings
fatigue
uneven progress
what are some education considerations for children with a TBI
- assist child as they transition from hospital/home to school
- create a plan for cognitive, social, and sensorimotor domains as relevant
- teach strategies for sustaining attention, remembering previously learned skills, learning new things, dealing with fatigue, engaging in social behaviour
- transition programming for long term needs
what are some tips when working with students who have a TBI
be patient
maintain clear structure/routines
do not set specific expectations for achievement too early
be supportive and responsive to changing needs
each case of TBI will be very…
UNIQUE! need to design a plan of intervention considering the unique qualities of the individual
TBI prevention programs in schools
playground safety
school bus and vehicle safety
pedestrian safety
youth violence awareness and prevention safety
