the rotator cuff pathology is mostly affecting the dominant arm
true
what are the causes of the rotator cuff pathology?

what is another secondary impingement part of SAPS? and what is it caused by?
- abnormal displacement of the ICR during elevation
- this is caused by soft tissue entrapment
describe the muscular imbalance of RC during the SAPS:

what is stage II of SAPS (Neer’s classification):
25-40 years old
symptoms > stage I

decreased PROM secondary to capsular fibrosis
what is stage III of SAPS (Neer’s classification):
