EMORY DPT KINES: EXAM three
objectives
Identify
1. The anatomy of the shoulder complex; AC, SC, GH and ST joint components - ANS-

Identify
2. The close-packed and open packed position for the shoulder complex - ANS-Open Packed
Position: 40 deg abduction in the scapular plane
Closed Packed Position: 90 deg GH abduction and full ER

Define
3. The terminology unique to the shoulder complex - ANS-Osteokinematics - movement of long
bones
Arthrokinematics - movement between joint surfaces: roll, spin and glide/slide

Convex and concave rules of motion:
Convex on concave = roll and glide occur in opposite directions
Concave on Convex = roll and glide occur in the same direction

Instantaneous center of rotation - the point fixed to a body undergoing planar movement that
has zero velocity at a particular instant of time.

Loose (open) packed position - the least amount of bony congruence

Closed packed position - the most amount of bony congruence

Kinetics:
Joint reaction forces -
Force couple - 2 forces of equal magnitude and opposite direction that produces rotation of a
segment (lever 1-3)

Define
4. The plane of the scapula - ANS-30° to 45° anterior to the frontal plane

Define
5. The humeral angle of inclination - ANS-humeral angle of inclination is formed by an axis
through the humeral head and neck in relation to a longitudinal axis through the shaft of the
humerus and is normally between 130° to 150° in the frontal plane

Define
