Translation
Movement in straight line ALONG an axis
Rotation
Movement AROUND an axis
Curvilinear motion AKA
Coupled movement
Coupled movement combines
Rotation and translation
Most common motion in the body
Coupled motion
Potential exists for each joint to exhibit
3 translational and 3 rotational movements
6 degrees of freedom
X-axis is at the junction of
Coronal and transverse planes
Y-axis is at the junction of
Coronal and sagittal planes
Z-axis is at junction of
Sagittal and transverse planes
X-axis is always
Horziontal
Y-axis is always
Vertical
Z-axis is always
Perpendicular to X (front to back)
X-axis positive and negative translation
\+ = to left - = to right
Y-axis positive and negative translation
\+ = superior - = inferior
Z-axis positive and negative translation
\+ = anterior - = posterior
