Name two muscles/muscle groups and their disfunction that may cause scapular
winging:
tight/shortened pectoralis muscles
Weak serratus anterior

What is scapular winging?

What is scapular tipping?

Name the muscles/muscle groups and their disfunction that may cause scapular
tipping:
- tight/short pectoralis minor muscle - Pec minor attaches to the scapula at the
coracoid process. If it is tight, it will pull it forward.
- Weak lower trap - responsible for a downward pull of the scapula. If you have a
weak lower trap and a tight pec minor, the resting position of the scapula will bias
towards anterior tipping.
- faulty posture (kyphosis)
