Appendix of Terminology
Planes of movement:
Extension: The increase in the angle of two articulating bones, in the sagittal plane; the return to neutral from the flexed position. Example: Bringing the leg from parallel passé back to standing position.
Hyperextension: Continuing of extension beyond anatomical neutral. Example: Arabesque involves hyperextension of the hip and the low back, which arches to achieve the full range of motion.
Abduction: The movement of a bone in the frontal plane away from the midline of the body. Example: Lifting the arms out to second position, or moving the leg directly side away from the body.
Adduction: The movement of a bone in the frontal plane towards from the midline of the body. Example: Lowering the arms from second position to straight down, or moving the leg from side back to neutral standing position.Outward rotation: Also called lateral or external rotation, the movement of a bone around its own axis, away from the midline of the body. Example: Both the hip joint and the shoulder outward rotate; standing in classical first is a position of outward rotation.
Inward rotation: Also called medial or internal rotation, the movement of a bone around its own axis, towards the midline of the body. Example: Both the hip joint and the shoulder inward rotate.
Supination: This movement term is used for both the forearm (radioulnar joint) and for the foot. Movement of the forearm in which the palm is turned anteriorly, or away from the midline of the body. When standing, supination occurs as the foot rolls outwards, placing most of the weight onto the outside of the foot and raising the arch. Supination combines inversion (moving the soles of the feet medially) and adduction of the foot. Example: When the foot is "sickled" it is supinated.
Pronation: This movement term is used for both the forearm (radioulnar joint) and for the foot. Movement of the forearm in which the palm is turned posteriorly, or towards from the midline of the body. When standing, pronation occurs as the foot rolls inward, placing most of the weight onto the inside of the foot and lowering the arch. Pronation combines eversion (moving the soles of the feet laterally) and abduction of the foot. Example: When the foot is "winged" it is pronated.
Plantar flexion: Bending at the ankle joint in the sagittal plane, so that the toes move away from the front of the shinbone. Example: Dancers call this "pointing the foot." Relevé is also an example of plantar flexion.
Dorsiflexion: Bending at the ankle joint in the sagittal plane, so that the toes move towards the front of the shinbone. Example: Dancers call this "flexing the foot." When the dancer pliés, dorsiflexion at the ankle increases.
