Quadriceps setting is widely used as a muscle strengthening exercise for the quadriceps femoris muscle. It is frequently employed from the early post-operative stage for patients receiving knee joint replacement surgery, such as total knee arthroplasty, at our hospital. Quadriceps setting is frequently performed with ankle joint dorsiflexion in the supine position. Patients performing quadriceps setting often say “I can’t understand where to flex the muscle in the leg.” Therefore, we analyzed this exercise in patients receiving knee joint treatments such as total knee replacement surgery. The patients were explained in a simple and easy-to-understand manner the correct way of performing quadriceps setting for efficient restoration of the quadriceps femoris muscle activity. In addition, we devised a quadriceps setting exercise involving knee extension and ankle dorsiflexion with the heel pressed down, encouraging simultaneous contraction of the quadriceps and gluteus maximus muscles, and analyzed the effectiveness of this exercise on quadriceps femoris muscle activity.
