ANATOMICAL BASES ON HUMAN MOTION

MOVEMENTS OCCUR IN PLANE

1) SAGITTAL PLANE - FLEXION - EXTENSION - HYPERTENSION - DORSIFLEXION - PLANTAR FLEXION 2) FRONTAL PLANE - ABDUCTION / ADDUCTION - LATERAL FLEXION - ELEVATION / DEPRESSION - INVERSION / EVERSION - RADIAL / ULNAR DEVIATION 3) TRANSVERSE PLANE - LEFT / RIGHT ROTATION - MEDIAL / LATERAL ROTATION - SUSPINATION / PRONATION - HORIZONTAL ABDUCTION / ADDUCTION

SPATIAL REFERENCE SYSTEMS

- STANDARDIZING DESCRIPTIONS OF HUMAN MOTION - USED CARTESIAN COORDINATE SYSTEM - HUMAN BODY JOINT CENTERS LABELED WITH NUMERICAL X / Y COORDIINATES

QUALITATIVE ANALYSIS

CONDUCTING THE ANALYSIS 1) IDENTIFY QUESTION / PROBLEM 2) MAKE DESICIONS - VIEWING ANGLE - VIEWING DISTANCE - PERFORMER ATTIRE - ENVIRONMENTAL MODIFICATIONS - USE OF VIDEO 3) COLLECT OBSERVATIONS - VISUAL - AUDITORY - FROM PERFORMER - FROM OTHER ANALYSIS 4) INTERPRET OBSERVATIONS 5) COMMUNICATE WITH PERFORMER REFINE QUESTION 6) END ANALYSIS

PLANNING - WHAT QUESTION TO BE ANSWERED - WHAT ANGLE / PERSPECTIVE SHOULD THE MOVEMENT VIEWED - HOW MANY OBSERVATIONS SHOULD BE TAKEN

PREQUISITE KNOWLEDGE - PURPOSE OF THE SKILL - CAUSE OF PERFORMANCES ERROR - HOW KNOWLEDGE CAN BE GAINED

DEFINITION

- ERECT STANDING POSITION WITH ALL BODY PARTS FACING FORWARD - STARTING POINT FOR ALL BODY SEGMENT MOVEMENTS

REFERENCES AXIS

i) MEDIOLATERAL AXIS - IMAGINARY LINE AROUND WHICH SAGITAL PLANE ROTATION OCCUR ii) ANTEROPOSTERIOR AXIS - IMAGINARY LINE AROUND WHICH FRONTAL PLANE ROTATION OCCUR iii) LONGITUDINAL AXIS - IMAGINARY LINE WHICH TRANSVERSE PLANE ROTATION OCCUR

ANATOMICAL REFERENCES PLANES

PLANES

1) SAGITTAL PLANES - FORWARD / BACKWARD MOVEMENTS 2) FRONTAL PLANES - LATERAL MOVEMENTS 3) TRANSVERSE - ROTATIONAL MOVEMENTS

TWO DIMENSIONAL SURFACED DEFINED BY SPATIAL COORDINATES OF THREE DISCRETE POINT

DIRECTIONAL TERMS

1) SUPERIOR - CLOSER TO HEAD 2) INFERIOR - FARTHER AWAY FROM HEAD 3) ANTERIOR - TOWARD FRONT OF BODY 4) POSTERIOR - TOWARD BACK OF BODY 5) MEDIAL - TOWARD MIDLINE OF BODY 6) LATERAL - AWAY FROM MIDLINE OF BODY 7) PROXIMAL - CLOSER TO TRUNK 8) DISTAL - AWAY FROM TRUNK 9) SUPERFICIAL - TOWARD SURFACE OF BODY 10) DEEP - INSIDE THE BODY AWAY FROM SURFACE
