Extremities
Unilateral
One side affected/included,
Left or Right
Bilateral
Both sides affected/included,
Left and Right
Contralateral
Opposite side affected,
Ex: stroke patients
Deep
Away from body surface
Superficial
Toward body surface
Supine
Lying face up
Prone
Lying face down
Coronal Plane
Front/back division (frontal)
Sagital Plane
Left/right division
Transverse Plane
Upper/lower division (horizontal)
Flexion
Bending movement that results in decrease of the angle in a joint by bringing bones together
Extension
Opposite of flexion,
Straightening movement that results in an increase of the angle in a join by moving bones apart
Plantar Flexion
Bottom of foot flexion,
Pointing toes down (inferior),
Standing on toes
Dorsal Flexion/Dorsiflexion
Top of foot flexion,
Pulling toes up (superior),
Standing on heels
Abduction
Lateral movement away from the midline of the trunk (shoulder/hip)
Adduction
Movement medially toward the midline of the trunk
Lateral Flexion
Lateral bending only of the head or trunk
Elevation
Shoulder (scapulae),
Jaw (TMJ),
Superior movement,
Ex: Shrugging, closing jaw, etc
Depression

Jaw (TMJ),
Inferior movement,
Ex: Opening jaw

Eversion
Plantar laterally (out, pronation), Ankle
Inversion
Plantar Medially (in, supination), Ankle
Ulnar Deviation
Medial bone of forearm,
Wrist
Radial Deviation
Lateral bone of forearm,
Wrist
Rotation
Left and Right,
Head, neck, trunk
External (lateral) Rotation
Away from midline (shoulder/hip)
