Posture

Question 1

What is Posture?

Answer 1

• relative alignment of body
• composite of positions of all joints
• least strain on structures
• least amount of muscular effort

Question 2

What is the ideal posture?

Answer 2

stable
mass over base of support
minimize stress and strain on tissues
minimize energy cost

Question 3

Physical Therapist job in analyzing posture

Answer 3

analyze body alignment in regard to gravity’s line of application
postulate what may cause abnormality
deviation from optimal result in unnecesary joint mvmnts
help guide test/measures

Question 4

5 things that affect posture

Answer 4

1. lack of flexibility/mobility
2. weakness
3. pain
4. built that way anatomically
5. habits

Question 5

BOS

Answer 5

Base of Support

-body part in contact with supporting surfave and area between supporting structures

Question 6

COG

Answer 6

Center of Gravity

• point around which mass of body is equally distributed
• anterior S1-S2

Question 7

Principles of Alignment, Joints, and Muscles

Answer 7

• faulty alignment= undue stress and strain
• joint positions indicate which muscle elongated/shortened
• relationship between alignment and muscle test findings if posture habitual
• muscle shortness brings origin and insertion closer
• adaptive shortening can develop in muscles that remain in short condition
• muscle weakness allows seperation of o/i
• stretch weakness occurs in one-joint muscles that remain elongate

Question 8

What is good posture

Answer 8

efficient
reduced stress on tissues
stable

Question 9

Answer 9

Head slightly forward
lobe of ear ->
bodies of cervical vert->
 shoulder joint->
 bodies of lumbar vertebrae->
 sacral promince->
slightly poster to hip joint->
slightly ant axis of knee joint->
