Common tests utilized in assessment of hamstring injury. A Puranen-orava. B, C Bent-knee stretch test. D Taking off the shoe. The Puranen-Orava test is performed on a low table or platform with knee fully extended and heel on platform. The patient hinges at the hips to stretch the hamstring. If pain is felt at the ischial tuberosity hamstring origination, this is a positive test. Bent-knee stretch test is performed by having the patient lay supine on the examination table. The examiner flexes both the knee and hip maximally on the patient’s affected side in line with the torso. The examiner then extends the knee. If pain is felt at the ischial tuberosity hamstring origination during knee extension, this is a positive test. Taking-off-the-shoe test is performed by having the patient stand up and capture the heel of the shoe on the affected side with the foot of their non-inured side. They are then asked to try and pull the foot of the affected leg out of the shoe while keeping the non-injured leg extended and still and hips level to the floor. This test is positive if they have difficulty completing the maneuver and/or pain in the ischial tuberosity during the attempt
