Impingement Sign test is a shoulder examination used to determine if there is any irritation or injury to the rotator-cuff tendons.
Patient seated or standing, 2 parts:
- Patient actively flexes shoulder with palm up (arm externally rotated).
- Patient actively flexes shoulder with palm down (arm internally rotated).
Positive Pain during active flexion → shoulder impingement
Positive Pain → Internally rotated shoulder → supraspinatus impingement
Externally rotated shoulder → biceps long head impingement.
Syn: Biceps Test, Straight Arm Test
Test should be followed up with Neer’s impingement test (passive shoulder flexion).
