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.

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.

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

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

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

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?

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.
