Module 2
why is it important to be excellant observers of human form and movement
skill development (coaching, training, injury risk reduction), Clinical (retraining, recovery, rehabilitation), occupational (task training, injury risk reduction)
How to do proper movement observation
- Language
- Line of sight (what plane is the motion occuring in, you want to view perpendicular to the motion)
- Differences between static and dynamic situation
- Focus on one joint in one plane at a time
- Be organized
- Recording to review
What is a static situation
Description of an image of the joint relative to the anatomical or neutral position, providing an estrimate of the joint angle and isolating the joint angle in a specific plane
What is a dynamic situation?
Assesing changes in joints over time or during phases throughout a video. Important to isolate joint movement in complex movement, requires repeated observations of a cycle or movement.
What is the stance phase
the stance phase is intitated when a fott strikes the ground and ends when it is lifted
What is the swing phase
The swing phase is initiated when the foot is lifted and ends when it strikes the ground again
what is one complete gait cycle
one complete gait cycle is the time interval of motions occuring between two consecutive initial contacts of the same foot. one gair cycle is one stride. Begins with heel strike of right foot to the following heel strike of the same foot. 2 steps in one gait cycle.
What occurs in the stance phase?
Heel strike (initial contact), foot flat (loading response), midstance (single leg stance), heel off (terminal stance), toe off (pre swing).
What occurs in swing phase
Acceleration (initial swing), midswing, deceleration (terminal swing)
