Ms. Harper is working with Chris McDaniel, a football player who is recovering from a knee injury. The muscles around his knee are weak from lack of use. Ms. Harper uses a dynamometer to compare the strength of his recovering leg to the strength of the uninjured leg. She determined that Chris could lift 70 pounds with his weak leg and 125 pounds with his strong leg. Use a proportion to determine the percent of strength of his injured leg. 2. Physical therapists usually set a goal of bringing an injured leg up to at least 90% of the strength of the strong leg at the end or their program. How many pounds should Chris expect his injured leg to lift at the completion of his physical therapy program? B. Extension Problems: 1.
