Posture

Question 1

Posture

Answer 1

Orientation of body parts relative to one another at any given time

• static and dynamic
• each weightbearing joint is considered a postural segment
• good alignment of postural segments = good posture

Question 2

Affects load on intervertebral discs

Answer 2

• supine 25%
• sidelying 75%
• standing 100%
• forward flexed 150%
• FF with weight 220%
• sitting 140%
• slouched sitting 185%
• slouched sitting with weight 275%

Question 3

Standing posture lateral view

Answer 3

Lateral view

• head through ear lobe
• shoulder through tip of acromion process
• T/S anterior to ventral bodies
• L/S through vertebral bodies
• pelvis level ASIS and PSIS alignment
• hip through greater trochanter
• knee slightly posterior to patella
• ankle anterior to lateral malleolus

Question 4

Standing posture posterior view

Answer 4

Posterior view

• head neutral
• shoulders bilaterally level
• scapulae superior angle and acromion level with T2; inferior angle T7 (more lateral than superior); medial angle 3 in from T/S;
• spinous processes centered in midline
• hips/pelvis PSIS level
• LE slightly apart
• knees level and not bowed or knock
• ankles straight calcaneus

Question 5

Standing posture anterior view

Answer 5

Anterior view

• head level
• shoulders bilaterally level
• sternum vertical
• hips/pelvis ASIS level
• LEs slightly apart
• knees level and not bowed or knocked
• ankles neutral arch
• feel slightl outward toeing

Question 6

Sitting posture

Answer 6

Lateral view

• head though ear lobe
• shoulder through tip of acromion process; shoulders not protracted nor retracted
• pelvis level ASIS and PSIS
• hip through greater trochanter, 90-100 degrees
• knee angle 90-100
• feet flat on floor or surface

Question 7

Supine

Answer 7

• firm surface to support normal curves of spine
• Same alignment as in standing but along horizontal plum line
• if neede, support under knees to maintain neutral lumbar lordosis and neutral pelvis

Question 8

Sidelying

Answer 8

• firm surface to support normal curves of spine
• horizontal alignment of spine segments
• bottom leg extended and top leg flexed with optional pillow between legs
