Painful Arc Test | Rationale & Interpretation

The video tutorial explains the painful arc test, a diagnostic tool for shoulder conditions like subacromial impingement syndrome and rotator cuff tears. It covers the test's procedure, psychometrics, and how to interpret results. The tutorial also discusses differentiating between these conditions and AC joint pathologies, highlighting pain patterns and compensation during shoulder abduction.

What is the primary purpose of the painful arc test?

• To diagnose subacromial impingement syndrome and rotator cuff tears

• To assess flexibility in the shoulder

• To evaluate elbow joint function

• To measure shoulder strength

What is the specificity of the painful arc test?

• 0.90

• 0.81

• 0.33

• 0.50

What range of motion is typically associated with a positive painful arc test?

• 0 to 45 degrees

• 45 to 120 degrees

• 120 to 180 degrees

• 0 to 180 degrees

How can the painful arc test help differentiate between a rotator cuff tear and impingement syndrome?

• By measuring shoulder strength

• By assessing pain in the elbow

• By evaluating pain throughout the entire range of motion

• By checking for pain only at the start of abduction

At what degree of abduction might AC joint pathology become apparent?

• 45 to 120 degrees

• 0 to 45 degrees

• 170 degrees and beyond

• 120 to 150 degrees

What is a distinguishing feature of an AC joint sprain compared to rotator cuff tears?

• No pain during shoulder abduction

• Pain in the anterolateral shoulder region

• Localized pain upon palpation of the AC joint

• Pain only during shoulder flexion

What compensatory movement might a patient exhibit during the painful arc test?

• Bending the elbow

• Hiking the shoulder

• Rotating the wrist

• Tilting the head
