Loop the other end around the knee of the affected leg, keeping the leg somewhat bent. Put your good leg a step behind the affected leg. Slowly straighten the affected leg by tightening its thigh muscles. Hold for six seconds before returning to the starting position. Rest for up to 10 seconds. Aim for 8 to 12 repetitions. [2]
