Some of the modalities that a physical therapist may utilize during your sessions include muscle strengthening exercises, balance training, and gentle electrical stimulation to the quadriceps or other muscles around the knee. The sessions may focus at one point on decreasing your swelling and, at another point, on increasing your range of motion through specific stretching movements. Your physical therapist may include exercises that will help you bear weight on the injured knee without the aid of a cane or crutches. Your therapist may also fit you with a brace, if necessary, and teach you how to safely walk with the brace supporting your knee. As you regain motion and mobility, the intensity of your exercises will increase gradually until you have achieved the strength, flexibility, and stability that you need to return to your normal level of activity.
