The straight leg raise, also known as the straight leg lift, is a valuable test to assess hamstring muscle flexibility. By raising the straight leg as far as possible while lying on their back, the tester can measure the angle of the leg from the horizontal position.
Purpose
The purpose of this test is to evaluate the range of hip flexion for each leg with the knee fully extended.

To perform the straight leg raise flexibility test, you will need a goniometer with extended arms and a spirit level (optional), as well as a firm table.
Pre-Test Procedures
Before conducting the test, it is important to explain the procedures to the subject. Additionally, perform a screening for potential health risks and obtain informed consent. You should also prepare necessary forms and record basic information such as age, height, body weight, gender, and test conditions. Lastly, ensure the subject adequately warms up.

Test Procedure
Here is a step-by-step guide on how to perform the straight leg raise flexibility test:
- The subject should lie supine on a flat bench.
- You will need at least two testers for this test. One tester will be responsible for raising the leg, while the other uses the goniometer to take measurements.
- The tester moving the leg should place one hand on the front of the leg, slightly below the knee, and the other hand at the heel.
- Prior to lifting the leg, ensure that it is fully extended and kept in this position throughout the movement without lifting the pelvis off the bench.
- Raise the straight leg as far as possible, and at the point of maximum stretch, measure the angle of displacement from the horizontal using the goniometer.
- The fulcrum of the goniometer should be placed over the greater trochanter of the leg being tested, while the moving arm should be aligned with the midline of the femur, using the lateral epicondyle as a reference point.
- Perform two separate trials for each leg, and record the mean of the two as the hip flexion score.

The goniometer will measure the angle of displacement from the horizontal in degrees.
Additional Tips
Here are a few additional tips to ensure accurate results:
- The opposite leg must be held firmly down by another tester or using a strap to prevent any flexion at the hip joint.
