Quadriceps Strength Test (QST)

Description: A measure of your ability to push your leg forward using your quadriceps muscles.

Equipment: Chair, and someone to work with you to offer resistance and feel how much you are able to move your leg.


Patient Instructions: “Sit on a tall table (such as a massage table) so your leg can move freely. A second person will sit in front of you and hold your ankle firmly. Once you both decide you are ready, your job is to push forward away from the table. The person holding your ankle will try to slow and stop your motion. This person will evaluate your ability to move.” See the key below.

Second Person/Therapist/Friend Instructions: Hold the patient’s leg at the ankle firmly while the patient pushes away from the table.

Results Key

The idea is to evaluate how much strength you are able to exert:

1. Full Resistance (normal quadriceps strength)

2. Moderate Resistance (mild quadriceps weakness)

3. Poor Resistance (severe quadriceps weakness)


X10 Knee Recovery System TwoThe Implications of Your Quadriceps Strength Test Score

If you scored a 2 or 3 on the test, you should pay attention to your quadriceps strength and ability to straighten your leg (extension). Read on as we have some insight for you below. Go to sections 3 and 4 for moderate and advanced exercises to strengthen and stretch your quadriceps muscles.

The quadriceps femoris is a group of muscles located in the front of the thigh. The Latin translation of ‘quadriceps’ is ‘four headed,’ as the group contains four separate muscles: the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris. Each of the vastus muscles originates on the femur bone and attaches to the patella, or kneecap. The three vastus muscles are also partially covered by the rectus femoris, which also attaches to the kneecap. However, unlike the vastus muscles, the rectus femoris inserts into the hip bone.
