Document Summary
Review of anatomical planes (frontal/coronal, sagittal, transverse) Joint posture is relative; zero must be defined: fully extended elbow can be 180 degrees of extension or 0 degrees of flexion. Axis of rotation that passes through a joint. Mediolateral (frontal, perpendicular to the sagittal), anterioposterior (sagittal, perpendicular to the coronal/frontal) pretty self-explanatory: if you want to see medial-lateral movement you need to observe from the frontal plane (ie the axis is perpendicular to the plane) Linear movement is translation: all the points move through the same distance: also includes curvilinear (linear movement through a curve) such as throwing a football. Rotation: all points move through the same angle angular motion about an axis. General motion: combination of the two above. Velocity is a vector describing speed and direction. Must be defined typically by constructing a free-body diagram drawing the segment in isolation (kelton"s drawings)
