Presentation Transcript

  1. Movement Terminology

  2. Course Content • Introduction to the Course • Biomechanical Concepts Related to Human Movement • Anatomical Concepts Related to Human Movement • Qualitative Analysis of Human Movement

  3. Movement Terminology • Types of motion • Reference systems • Fundamental movements in the sagittal plane • Fundamental movements in the frontal plane • Fundamental movements in the transverse plane

  4. Types of Motion • motion – change in position with respect to some reference frame • What causes motion? Force!!!

  5. – Point Model Linear Motion curvilinear rectilinear translation Definition Role of COG?

  6. – Link Model Angular Motion Axis – fixed or moving Role of COG? rotation Definition

  7. General Motion

  8. Reference Positions Fundamental Standing Position Anatomical Standing Position Fig 2.9

  9. Sagittal Plane Mediolateral (ML)Axis Planes & Axes Frontal Axis Bilateral Axis 2-6

  10. Sagittal Plane Mediolateral (ML)Axis Frontal Plane Anteroposterior (AP) Axis Sagittal Axis 2-6

  11. Sagittal Plane Mediolateral (ML)Axis Frontal Plane Anteroposterior (AP) Axis Transverse Plane Superior-Inferior (SI) Axis Longitudinal Axis Vertical Axis 2-6

  12. Movement Terminology • Types of motion • Reference systems • Fundamental movements in the sagittal plane • Fundamental movements in the frontal plane • Fundamental movements in the transverse plane

  13. Sagittal Plane – Fundamental Movements • Flexion • Extension • Hyperextension • Hyperflexion • Plantar flexion • Dorsiflexion Flexion and extension do not refer to muscle contraction!!!

  14. Frontal Plane – Fundamental Movements • Abduction • Adduction • Left lateral flexion • Right lateral flexion • Hyperabduction • Hyperadduction • Radial deviation • Ulnar deviation • Inversion • Eversion To observe, look at the plane, down the axis!!!

  15. Transverse Plane – Fundamental Movements • Medial rotation • Inward, Internal • Lateral rotation • Outward, External • Left rotation • Right rotation • Supination • Pronation Forearm in neutral position

  16. Transverse Plane – Fundamental Movements • Horizontal adduction • Horizontal abduction

  17. Other Points • Circumduction combines sagittal (flexion, extension) and frontal plane (abduction, adduction) motions. • Although inversion & eversion occur around the long axis of the bone like transverse plane movements, they are considered frontal plane movements because of the orientation of the foot in anatomical position. • All movements defined in this slide show are rotational movement, even though we use the word rotation only for transverse plane motions.

  18. Other Points (cont.) • Not all joints permit movement in all 3 planes – learn the planes of movement associated with each joint. • Movement terms for each plane vary across joints – learn appropriate terminology for each joint.
