  1. Introducton to Labanotation Edward Chow Reference: http://www.dance.ohio-state.edu/5_resources/labanlab/welcome.html http://viva.uccs.edu/~hmtr/doc/laban/

  2. Outline of the Talk • Quick overview of LABAN notation • The four Key Exercises and our initial interpretation, using LABAN notation • Observed inadequacy in LABAN notation • Suggested LABAN notation extension • Discussion FJ/Chow

  3. Overview of Labanotation • Like music notes with five line left to right. • Develop by Rudolf Laban (1879-1958), • Labanotation has three solid lines bottom up. • The movements of each body parts is specified in a designated strip. FJ/Chow

  4. Review of LabanBodySign FJ/Chow

  5. Movement Direction Symbols FJ/Chow

  6. 1 - mini-squats: Muscle group – hips • Start standing with equal weight distributed between right and left legs. • Place feet shoulder width apart. • Keep torso upright, avoid bending at the waist. • Slowly lower yourself by bending at the ankles, knees and hips. • Return to standing. FJ/Chow

  7. 2 - posterior pelvic tilt: Muscle group - abds, pelvis • Start lying supine/ on your back. • Bend legs up so both feet are on the supporting surface/ table. • Slowly tighten abdominal muscles to flatten your low back into the table. • Avoid pushing through your legs FJ/Chow

  8. 3 - Shoulder elevation with rotation:    Multiple muscles around the scapula and shoulder • Start standing, with right hand/palm placed on the front of the left hip. • Slowly, begin to elevate the right upper extremity to shoulder height. At the same time, rotate the right arm outward so the thumb is pointing toward the ceiling. • Keep the elbow straight throughout. • Lower the arm and return to the start position FJ/Chow

  9. 4 - standing hip ABD (abduction):  Muscle group – hips • Start standing with equal weight distributed between the right and left legs. • Slowly, shift your weight to the left side. • Raise the right leg out to the side ~ 12”. • Keep the right foot facing forward. • Keep the torso upright and avoid leaning to the side FJ/Chow

  10. Observed Laban Encoding Problems 1.   mini-squats: Muscle group – hips Place feet shoulder width apart 2.   posterior pelvic tilt: Muscle group - abds, pelvis Slowly tighten abdominal muscles to flatten your low back into the table 4.  standing hip ABD (abduction):  Muscle group – hips Raise the right leg out to the side ~ 12” FJ/Chow

  11. Suggest Labanotation Extension Raise the right leg out to the side ~ 12”; (a: 12’’) FJ/Chow

  12. Suggest Labanotation Extension Place feet shoulder width apart; (r:w( )) (r:w( )) FJ/Chow

  13. Suggest Labanotation Extension Slowly tighten abdominal muscles to flatten your low back into the table Solution: express that with contraction symbols ? Which one FJ/Chow

  14. Potential Future Directions • Examine other rehab exercises and improve/customize the labanotation for rehab exercise specification • Need Susan Kanal’s help for a common set of rehab exercises. • Suggestion? FJ/Chow

  15. Sensor Tracking Problems • How to compare the rehab model specified with labanotation with the sensor tracking data? • Approach one: Translate/recognize 3D-time sensor data into labanotation and then compare with rehab model. • Approach two: Convert animated rehab model data as 3D-time sequence; then compare directly with 3D-time sensor tracking data. FJ/Chow
