1

Movement

Represents the integrated functioning of the 3 main systems within the body

2

Biomechanics Definition

The study of applying laws of mechanics and physics to determine how forces affect human movement

3

Superior

Positioned above a point of reference

4

Inferior

Positioned below a point of reference

5

Proximal

Positioned nearest the center of the body, or point of reference

6

Distal

Positioned farthest from the center of the body, or point of reference

7

Anterior (Ventral)

On the front of the body

8

Posterior (Dorsal)

On the back of the body

9

Medial

Positioned near the midline of the body

10

Lateral

Positioned toward the outside of the body

11

Contralateral

Positioned on the opposite side of the body

12

Contralateral EX

Right foot is contralateral to left hand

13

Ipsilateral

Positioned on the same side of the body

14

Ipsilateral EX

Right foot is ipsilateral to right hand

15

3 Planes of Motion

Sagittal, Frontal, Transverse

16

Motions in Those Planes

No motion occurs strictly in one plane of motion
-Joint Motion

17

Joint Motion

Movement in a plane occurs on an axis running perpendicular to that plane

18

Sagittal Plane Division

Divides body into left and right halves

19

Sagittal Plane Motion Axis

Sagittal plane occurs around a coronal axis

20

Movements in Sagittal Plane

Flexion and Extension

21

Flexion

Decreasing joint angle

22

Extension

Increasing joint angle

23

Hyperextension

Extension of a joint beyond the normal limit or range of motion

24

Dorsiflexion

Point toe up (Flexion)

25

Plantar Flexion

Point toe down (Extension)

26

Knee Flexion

Bring heel to butt

27

Knee Extension

Moving heel away from butt at the knee

28

Hip Flexion

High Knee and bend forward at trunk as if touching toes

29

Hip Extension

Knee straight, push heel back

30

Spinal Flexion

Arch back forward
