Force Couples For Scapulohumeral Rhythm Flashcards
(3 cards)
1
Q
Upper trapezius and serratus anterior (upper force couple)
A
Work together to upwardly rotate scapula. Allowing glenoid fossa to remain in an optimal position for humeral elevation.
2
Q
Middle trapezius and serratus anterior (middle force couple)
A
Stabilises the scapula during arm elevation. Ensuring proper alignment and movement.
3
Q
Lower trapezius and serratus anterior (lower force couple)
A
Facilitates posterior tilt and external rotation of the scapula during arm elevation. Enhancing the subacromial space and preventing impingement.
