Reference Systems
Reference Systems Why? Absolute vs Relative
Absolute Reference Frame Segments intersect
in joint center & movement of segment is described with respect to that joint
Reference Systems Why? Absolute vs
Relative Absolute Reference
Frame Relative Reference
Frame Movement of
segment described relative to adjacent segment
Reference Systems Spatial Reference
Frame Movement of body
relative to ground Occurs in xyz
directions
x
y
zForward (+)
Backward (-)
Left (+) Right (-)
Up (+)
Down (-)
Reference Systems Cartesian
Coordinate System Fixed reference
point x,y and z
coordinates
Anatomical Planes & Axes
Plane of Motion 2 dimensional flat surface
Axis point about which movement occurs perpendicular to the plane of movement
Whole Body Planes and Axes Segmental Planes and Axes
Anatomical Planes
Planes of movement Sagittal
left/right halves Perpendicular Axis -
Frontal or Mediolateral
Planes & Axes Frontal Plane
Anterior/posterior halves
Axis - Anteroposterior or Sagittal
Planes & Axes Transverse Plane
Upper/lower halves Axis - Longitudinal
Other Planes and axes Diagonal or
Oblique plane of movement perpendicular to
the plane how to find
