Basic Alignment/Posture

Question 1

From a lateral prospective, where should the plume line fall at the head and neck?

Answer 1

through the ear lobe to the acromion process

Question 2

From a lateral prospective, where should the plume line fall at the shoulders?

Answer 2

through the acromion process

Question 3

From a lateral prospective, where should the plume line bisect the thoracic vertebrae?

Answer 3

The line bisects the chest symmetrically

Question 4

From a lateral prospective, where should the plume line fall through the lumbar vertebrae?

Answer 4

midway between the abdomen and back and slightly anterior to the sacroiliac joint

Question 5

From a lateral prospective, where should the plume line fall through the pelvis and hip?

Answer 5

posterior to the hip joint, through the greater trochanter, creating an extension moment

Question 6

From a lateral prospective, where should the plume line fall at the knee?

Answer 6

anterior to the midline of the knee, creating an extension moment

Question 7

From a lateral prospective, where should the plume line fall at the ankle?

Answer 7

slightly anterior to the lateral malleolus, aligned with tuberosity of 5th metatarsal

Question 8

What is the standard anatomical position of the pelvis?

Answer 8

anterior

Question 9

Anatomical vs. functional leg length inequality

Answer 9

Anatomical LLI refers to a leg which is physically shorter than the other due to unequal growth rates, fractures, or deformities.
Functional LLI both legs are be identical in length, but one functions as if it were shorter because of either a postural imbalance in the body or uneven muscle contractions between the two legs.

Question 10

What is the most common cause of functional leg length inequality?

Answer 10

excessive pronation of the feet or dropped arches

Question 11

If one is sitting with correct posture where should the center of gravity be in reference to the ischia? Where is it in the slouched sitting position?

Answer 11

Anterior to the ischia

Posterior to the ischia

Question 12

Is lumbar IVD pressure higher in sitting or standing? Why?

Answer 12

Sitting, because disc pressure increases with the tendency toward lumbar kyphosis

Answer 13

18

Question 14

During sitting __% of body weight is distributed over each thigh

Answer 14

21

Question 15
