Lecture 4: Posture and Respiration Flashcards
What are some factors that influence posture?
health, body build, strength, gender, endurance, and kinesthetic awareness
Which type of posture is unnatural and can impede blood flow?
Static posture
Good posture is a state of _________ and _________ balance
Muscular and skeletal
What type of posture is ever changing, difficult to assess, and individual patterns can be developed
Dynamic posture
position in which you hold your body upright against gravity while standing, sitting, or lying down
posture
T/F: Muscles that are active are dependent on where the Line of Gravity (LOG) falls
True
If the LOG is in front of joint, anterior pull by gravity must be offer by pull of muscles ______________
posteriorly
What is this describing?
- Side View
- Through mastoid process
- just in front of or through acromion process
- through hip joint or just behind
- just in front of center of knee joint
- through lateral malleolus
Normal erect posture
What are some requirements of good posture?
good muscle flexibility, normal ROM in the joints, strong and balanced postural muscles, body awareness, endurance, good health
Faulty relationship of parts of body, inadequate balance over the base of support, bones and joints become misaligned, increases normal wear of joints, increases stress on ligaments, causes poor balance over base of support
Poor posture
Name some causes of poor posture
Lack of knowledge, poor habits, poor environment, injury or illness, weak muscles, decreased flexibility, neurological damage
Name some types of poor posture
Chronic pain condition causes person to lean to one side; weakness (stroke), spasticity, scoliosis, kyphosis, lordosis
Lateral deviation of spine
scoliosis
increased posterior convexity of thoracic spine (hunchback)
kyphosis
increase concavity in lumbar or cervical spine (big butt)
lordosis
What are some ways that OTs can correct deficits in posture?
adapt environment, assistive devices, and activity modification
The diaphragm and the external intercostals are muscles of ________ inspiration
relaxed
T/F: Accessory muscle of inspiration participate in resting respiration
False
Sternocleidomastoid, upper trapezius, scalenes, serratus anterior, pec major and minor, and latissimus dorsi are ________ muscles of inspiration
accessory
T/F: Expiration is a passive process with no muscular activity
true
Rectus abdominus, internal and external obliques, transverse abdomens, and internal intercostals are muscle of ______________
expiration
Thorax enlarges in ____ planes with inspiration
3 (all three)
What is this describing?
Diaphragm contracts, lungs are pulled downward filling with air, ribs flare outward, thorax enlarges
Inhalation
What is this describing?
diaphragm relaxes and returns to resting position, lungs empty and are reduced in size, ribs lower, thorax relaxes
Exhalation
