BIOMECHANICS CHAPTER 2

The anatomical reference position serves as the baseline for describing all movements of body segments, characterized by an erect standing posture with all body parts facing forward.

BIOMECHANICS CHAPTER 2

REFERENCE PLANES

transverse plane
rotational movements

movements occur - horizontal abduction, adduction - supination, pronation - medial, lateral pronation

frontal planes
lateral movements

movements occur - abduction, adduction - elevation, depression - radial, ulnar deviation

sagittal plane
forward and backward movements

movements occur - flexion - extension - hyperextension

REFERENCE AXES

longitudinal axis
imaginary line around transverse plane rotations
anteroposterior plane
imaginary line around frontal plane rotations
mediolateral axis
imaginary line around sagittal plane rotations

SPATIAL REFERENCE SYSTEMS

human joint centers are labeled with numerical x and y
commonly used is Cartesian coordinate system
standardizing descriptions of human motion

QUALITATIVE

PLANNING - performer attire - lighting condition - background - use of video
ANALYSIS - description of quality without use numbers - visual observation is most commonly used approach

ANATOMICAL REFERENCE PLANES

cardinal planes
three imaginary
planes
two dimensional surface

DIRECTIONAL TERMS

deep
inside body, away from surface
superficial
toward surface body
distal
away from trunk
proximal
closer to trunk
lateral
away from midline
medial
toward midline body
posterior
toward back body
anterior
toward front body
inferior
farther away from head
superior
closer to head

ANATOMICAL REFERENCE POSITION

considered starting point for all body segment movements
all body parts facing forward
erect standing position
