The purpose of this study is to determine if a lower extremity strengthening program as part of pulmonary rehabilitation will improve quadriceps muscle strength, endurance and functional status as well as overall quality of life.


  1. Lower extremity resistance training as part of a pulmonary rehabilitation program will improve quadriceps strength, endurance and functional capacity.
  2. Lower extremity resistance training as part of a pulmonary rehabilitation program will improve quality of life in patients awaiting lung transplant.

Further study details as provided by University of Chicago:

Primary Outcome Measures:
  • Quadriceps Strength [ Time Frame: 10 weeks ] [ Designated as safety issue: No ]
    Quadriceps Strength will be assessed at initial evaluation and subsequently every two weeks for 10 weeks. Testing will be done at 30, 60 and 90 degrees of knee flexion using hand held dynamometer. The six miute walk test is also used as a primary outcomes to assess endurance. It will be done at initial evaluation, 5 weeks and 10 weeks.

Secondary Outcome Measures:
  • Quality of Life Survey [ Time Frame: 10 weeks ] [ Designated as safety issue: No ]
    The St. George Respiratory Questionnaire will be used to assess quality of life at initial evaluation and at 10 weeks (completion of program).

Estimated Enrollment: 15
Study Start Date: March 2010
Estimated Study Completion Date: January 2014
Estimated Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Other: Exercise
    Lower extremity resistance exercises and aerobic exercises 3 times a week in 10 week pulmonary rehabilitation program prior to lung transplant.
Detailed Description:


  1. To determine if a lower extremity strengthening program as part of pulmonary rehabilitation is effective at increasing quadriceps strength when measured with a hand held dynamometer.
  2. To determine the effectiveness of a lower extremity strengthening program as part of pulmonary rehabilitation for improving endurance and functional capacity as measured by the six minute walk test.
  3. To determine if the lower extremity strengthening program as part of pulmonary rehabilitation improves overall quality of life as measured by the St. George's Respiratory Questionnaire.
  4. To provide a basic framework for a larger randomized control study evaluating if a lower extremity strengthening program as part of a pulmonary rehabilitation program is more effective than a pulmonary rehabilitation program alone at improving quadriceps strength, endurance, and functional level.
