Forms of Motion Flashcards
Linear Motion
motion going the same direction. distance, time
along the line
Rectilinear motion
along a straight line
Curvilinear motion
along a curved line
Angular motion
rotation around an axis
General motion
A combo of linear/angular motion
common for human motion
Mechanical System
body or portion of a body that is deliberately chosen by the analyst.
Ex. throwing arm, kicking leg, jump max

Pronation of Foot
triplanar: abduction
eversion
dorsiflexion
Supination of Foot
triplanar: adduction
inversion
plantarflexion
Arch type
Foot alignment
normal arch: neutral alignment
High arched print: supinatior rolls, outside/lateral
Flatfoot print: pronator rolls to inside/medial
Special Movements
circumduction
thumb opposition

Spatial Reference Systems
describes human motion
most common: cartesian coordinate system (x,y)
Qualitative Analysis: Planning
Used for Performer's attire Lighting Conditions Background Use of Video
Gait Cycle
Stance Phase
Loading Response
Midstance
Terminal Stance
Pre Swing
Loading Response
Begins with initial contact and ends with contralateral toe off
Midstance
Begins with contralateral toe off and ends when COG is directly over the reference foot
Terminal Stance
Begins when COG is directly over the reference foot and ends with the contralateral foot contacts the ground
Pre Swing Starts…
with the contralateral foot contacts the grounf and ends at toe off (reference foot)
Gait Cycle (Swing Phase)
Initial Swing
Midswing
Terminal
Initial Swing
Starts with toe off and ends with maximum knee flexion (reference foot)
Mid Swing
Starts with the max knee flexion and ends with the tibia being perpendicular to ground (reference foot)
Terminal Swing
Starts with the tibia in perpendicular to ground and ends when the foot contacts the ground (reference foot)
