Transcript of "Kin191 A. Osteokinematics. Fall 2007"

  1. 1. Osteokinematics KIN 191A Advanced Assessment of Lower Extremity Injuries
  2. 2. What is It? <ul><li>Kinesiology: The scientific study of human movement (anatomical, physiological, & mechanical) </li></ul><ul><li>Biomechanics: The study of the body motion and the forces acting on the musculoskeletal system to effect motion </li></ul>
  3. 3. Kinematics Vs Kinetics <ul><li>Kinematics: The branch of biomechanics concerned with description of the movements of segments of the body w/o regard to the forces that caused the movement to occur </li></ul><ul><li>The study of motion </li></ul><ul><li>Kinetics: The forces acting on the body during movement and the interactions of sequence of motion with respect to time and forces present </li></ul><ul><li>The study of the forces that effect motion </li></ul>
  4. 6. Kinematics <ul><li>Movement: A change in the position of a bone or segment (i.e., forearm flexion); or a change in the relationship of two adjacent bones or segments (i.e., elbow flexion) </li></ul><ul><li>In describing joint movement in the extremities, the distal segment is compared to the proximal segment </li></ul><ul><li>In describing joint movement in the spine, the cranial segment is compared to the caudal segment </li></ul>
  5. 7. Kinematics cont. <ul><li>Osteokinematics: Description of movement with reference to the bones </li></ul><ul><li>Arthorkinematics: Description of movement with reference to the joint surfaces </li></ul>
  6. 8. Planes of the Body <ul><li>1. Sagittal plane </li></ul><ul><li>2. Frontal (coronal) plane </li></ul><ul><li>3. Transverse (horizontal) plane </li></ul>
  7. 9. Axes Z X Y
  8. 10. Sagittal plane Transverse plane Frontal plane Y Z X
  9. 11. Axes of Rotation <ul><li>Sagittal Plane </li></ul><ul><ul><li>Motion occurs about a mediolateral axis </li></ul></ul><ul><li>Frontal Plane </li></ul><ul><ul><li>Motion occurs about an anterior-posterior axis </li></ul></ul><ul><li>Transverse Plane </li></ul><ul><ul><li>Motion occurs about a longitudinal axis </li></ul></ul>
  10. 12. Types of Osteokinematic Motion <ul><li>Rotary (angular): 3 degree of freedom, around a certain axis (X,Y, & Z) in a certain plane (sagittal, frontal, or transverse). The axis and plane are always orthogonal </li></ul><ul><li>Translatory (linear): motion through space in a straight line w/o rotation. It is usually described as forward/back, up/down, side to side, or some combination of the three </li></ul><ul><li>Curvilinear: a combination of rotary and translatory </li></ul>
  11. 13. Degrees of Freedom <ul><li>Refers to the type and amount of motion structurally allowed by joint anatomy </li></ul><ul><ul><li>1 df: has a single axis of rotation </li></ul></ul><ul><ul><ul><li>Example - elbow </li></ul></ul></ul><ul><ul><li>2 df: dual axes of rotation </li></ul></ul><ul><ul><ul><li>Example - wrist </li></ul></ul></ul><ul><ul><li>3 df: three axes of rotation </li></ul></ul><ul><ul><ul><li>Example - shoulder </li></ul></ul></ul>
  12. 14. Movement Terminology 1 <ul><li>Flexion: Movement in the Sagittal plane, from the anatomical position </li></ul><ul><ul><li>An exception is the thumb (motion occurs in the frontal plane) </li></ul></ul><ul><li>Extension: Movement in the Sagittal plane, back to the anatomical position </li></ul><ul><li>Hyperextension: Movement in the Sagittal plane from the anatomical position, but in the opposite direction of flexion (toward the direction of the least available motion) </li></ul>
  13. 18. Movement Terminology 2 <ul><li>Abduction: Movement in the Frontal plane, away from the midline of the body or segment </li></ul><ul><li>Horizontal Abduction: Movement in the Transverse plane, away from the midline of the body or segment (used for the hip and shoulder) </li></ul><ul><li>Adduction: Movement in the Frontal plane, toward the midline of the body or segment </li></ul><ul><li>Horizontal Adduction: Movement in the Transverse plan, toward the midline of the body or segment (used for the hip and shoulder) </li></ul>
  14. 19. Movement Terminology 2 cont. (Abduction & Adduction) <ul><li>Exceptions </li></ul><ul><ul><li>Thumb (motion occurs in the sagittal plane) </li></ul></ul><ul><ul><li>Foot (motion occurs in the transverse plane) </li></ul></ul><ul><li>Finger (the midline of the hand: 3rd finger) </li></ul><ul><li>Toe (the midline of the foot: 2nd toe) </li></ul>
  15. 22. Movement Terminology 3 <ul><li>External Rotation: Movement in the transverse plane along the long axis of the segments so that the reference point turns out ( away from the midline of the body) </li></ul><ul><li>Internal Rotation: Movement in the transverse plane along the long axis of the segments so that the reference point turns in ( toward the midline of the body) </li></ul>
  16. 25. Movement Terminology 4 <ul><li>Inversion: Foot movement, so that the reference segment (bottom of foot) moves toward the midline of the body ( Frontal plane) </li></ul><ul><li>Eversion: … moves away from the midline of the body ( Frontal plane) </li></ul><ul><li>Pronation (foot): Triplan a r movement which combines the movements of ev ersion, abd uction, & d orsi f lexion in one movement </li></ul><ul><li>Supination (foot): … the movement of in version, add uction, & p lantar f lexion in one movement </li></ul>
  17. 26. Movement Terminology 5 <ul><li>Pronation (forearm): Movement turning the palm of the hand down </li></ul><ul><li>Supination (forearm): Movement turning the palm of the hand up </li></ul><ul><li>Ulnar Deviation: Wrist _adduction__ </li></ul><ul><li>Radial deviation: Wrist abduction </li></ul>
  18. 28. Movement Terminology 6 <ul><li>Dorsi Flexion: Foot movement towards the dorsal surface </li></ul><ul><li>Plantar Flexion: Foot movement towards the plantar surface </li></ul>
  19. 30. Movement Terminology 7 <ul><li>Lateral Flexion: Movement from midline in the frontal plane (occur in neck and trunk) </li></ul><ul><li>Protraction: Movement of a segment anteriorly </li></ul><ul><li>Retraction: Movement of a segment posteriorly </li></ul>
