Measuring knee flexion at home is a simple process that can be done with a few household items. It is important to measure knee flexion accurately in order to track progress in rehabilitation or to assess the severity of an injury.
To measure knee flexion at home, you will need a tape measure, a chair, and a wall. Sit in the chair with your feet flat on the floor and your knees bent at a 90-degree angle. Place the tape measure on the top of your thigh, just below your kneecap. Bring the tape measure down to the bottom of your heel. The measurement you get is your knee flexion angle.
