The video tutorial explains the hamstring muscle length test, also known as the 9090 test. It describes the procedure, where the patient lies in a supine position with the hip and knee at 90 degrees. The physical therapist stabilizes the thigh and extends the knee to measure hamstring length. Normal range is defined as a knee angle between full extension and 20 degrees short. A positive test indicates hamstring tightness if the knee is more than 20 degrees short of full extension. The video also covers how to measure knee angles and interpret results.
