Practical skills of the shoulder region Flashcards
what are the limiting factors for elevation of the shoulder girdle?
SCJ joints- tension in costoclavicular ligs and subclavius
ACJ- Coracoclavicular ligs (both bands)
what are the limiting factors of depression at the SCJ?
Interclavicular lig and intra-articular disc
what are the limiting factors for protraction at the shoulder girdle
SCJ- sternoclavicular and costoclavicular ligaments
ACJ- coracoclavicular ligament and fibrous capsule
what are the limiting factors for retraction at the shoulder girdle
SCJ- sternoclavicular and costoclavicular ligaments
ACJ- Coracoclavicular lig and fibrous capsule
what is normal ROM for flexion at the glenohumeral joint
0- 110 degrees (180 degrees)
what is normal ROM for extension at the glenohumeral joint
0-70 degrees
what is normal ROM for ABduction at the glenohumeral joint
0-120 degrees
what is normal ROM for medial rotation at glenohumeral joint
0-80 degrees
what is normal ROM for lateral rotation at glenohumeral joint
0-90 degrees
limiting factors flexion glenohumeral joint
tension in capsular structures and surrounding opposing musculature
limiting factors extension glenohumeral joint
tension in capsular structures and opposing musculature
limiting factors abduction glenohumeral joint
glenohumeral ligs (middle and inferior bands) and inferior part fibrous capsule
what 3 tests can be used to test for sub acromial pain syndrome (SAPS)
-hawkins kennedy test
-infraspinatus muscle test
- painful arc test
How many positive test results would indicate SAPS
If all 3 tests are positive, high likelihood SAPS is present,, 2 positive results indicates moderate likelihood of SAPS
how would you conduct hawkins kennedy test
patient’s shoulder and elbow both flexed to 90 degrees
arm is medially rotated (pushed downwards)
what is a positive test of hawkins kennedy test
model experiences familiar pain
how to conduct infraspinatus muscle test
patients elbows flexed at 90 degrees, while keeping them to their side
therapist applies pressure on outer surface of forearm, pushing inwards, patient should resist this
positive test for infraspinatus muscle test
model experiences familiar pain or weakness
how to conduct painful arc test
model asked to abduct shoulder through full available range of motion, and then lower back down in controlled manner bck to their side
model asked to speak of any pain as soon as it is felt
positive test for painful arc test
model experiences pain between 40-120 degrees of abduction, which eases below 40 degrees or higher than 120 degrees
how to conduct drop arm test
model is asked to abduct arm to 90 degrees
they then slowly lower arm back to side
positive test of drop arm test
pain or weakness experienced, which causes arm to drop
what 3 tests, when combined are all positive indicate a very likely full tear of the rotator cuff
painful arc test
infraspinatus test
drop arm test
which specific rotator cuff muscle does the drop arm test target
supraspinatus
which specific rotator cuff muscle does the bear hug test target
subscapularis
how to conduct bear hug test
model places hand of affected arm on opposite shoulder
physio tries to pull hand up off of the shoulder
positive test for bear hug test
patient not able to resist external rotation force applied by physio- due to pain or weakness
if affected arm displays weakness compared to other arm
which rotator cuff muscle does the hornblowers test target
teres minor
how to conduct hornblowers test
patient’s shoulder and elbow both at 90 degrees
they maintain position, and instructed to say as soon as any pain is felt
positive hornblowers test
unable to hold position due to pain or weakness
what does the scarf test, test for
ACJ dysfunction
how to conduct scarf test
patient reaches over to other hsoulder
physio applies pressure with one hand, holds on to the shoulder with the other
what is a positive scarf test, and why does it demonstrate ACJ dysfuction
pain produced in the region of the ACJ
the test compresses the joint surfaces of the ACJ together
