(L2) Motion Dynamics

Question 1

What plane/axis is associated with flexion/extension?

L2 S10-11

Answer 1

Sagittal plane

Left/right axis

Question 2

What plane/axis is associated with abduction/adduction?

L2 S10;12

Answer 2

Frontal/coronal plane

Anterior/posterior axis

Question 3

What plane/axis is associated with rotation?

L2 S10;13

Answer 3

Transverse plane

Cranial/caudal axis

Question 4

What change occurs in ROM with somatic dysfunction?

L2 S20

Answer 4

Loss of active range of motion

Compensation of partial extension of active ROM into elastic range in opposite direction (shift of midline)

Question 5

What is a functional unit of the spine?

How is a functional unit named?

L2 S26

Answer 5

Consists of:

• two vertebrae
• disc
• neurovascular structures
• soft tissues

Functional unit named from top vertebra

Question 6

What end feel do skeletal, arthrodial, myofascial, vascular, lympatic, and neural dysfunction have?

L2 S52-53

Answer 6

Skeletal: hard end point
Arthrodial: hard end point
Myofascial: tight or elastic end point
Vascular: empty end point
Lymphatic: empty or boggy end point
Neural: crisp or empty end feel
