leukemia
dental problem
cognitive
hearing
respiratory
what do we evaluate in down syndrome
posture
compensation
stability
strength
what is the aim of the bms for DS
to score specific motor behaviours
shows developmental period btw 0-36 mnths
measures and scores specific movement disorders
valid and reliable measurement method
what is seen in the motor development disorders
dec musc tone
insuff co contractions
jont hypermob
dec proprio
aim of pt in DS
incre tone
incre msc strength
reduce -ve effect of hypotonia
to prevent spinal and other joint disordera
What are the main principles of the pt
facilitation
stimulation
communication
inhibition
why is the supine position okay for the baby
corrects abduction of the arm
stabilize the trunk
corrects leg hyperabduction
easy for arms and leg to work against gravity
why is side position good also
provides active momement of upper arm and leg
stabilize underlying body parts
prepares baby for rotation
activities to support motor development steps
head control
crawling
standing on knee
standing and walking
pt aims for children between the age of 0-2
increase the joint stability
reduce negative balance
provide child with good posture haibts
take precautions against posture disorders
pt aims for children over two years
incr speed and endurance
