What is lift off test used for?
Purpose. Gerber’s test also known as Lift-Off Test (LOT) or Gerber’s Lift-Off Test. It was first described by Gerber and Krushell(199l). It was developed to be used as a simple clinical manoeuvre, which can reliably diagnose or exclude clinically relevant rupture of the subscapularis tendon.
What does a positive lift off test mean?

How accurate is the lift off test?
In addition, the lift-off test was found with 62.5% sensitivity, 68.9% specificity, 67.6% accuracy, 35.7% PPV and 86.9% NPV.
