The long arc quad exercise is a popular physical therapy exercise designed to target the quadriceps muscles in the front of the thigh. These muscles play a crucial role in maintaining lower limb function and are essential for activities of daily living, including walking, standing, and sitting. This exercise is particularly useful for individuals who have experienced knee pain or injury, as it can help to strengthen the quadriceps and improve knee extension range of motion (ROM).
