This study will test whether using the Biodex BioStep Semi Recumbent Elliptical for the chronic obstructive pulmonary disease (COPD) patient with arthritic limitations will improve participation in a pulmonary rehab program compared to the Nustep elliptical. The main outcome of participation will be measured by the number of exercise sessions the patient is able to complete during their pulmonary rehabilitation program. In addition, distance walked in six minutes, dyspnea score, rate of perceived exertion (RPE) score, Pain Scale Index score, and finally, the Dartmouth Quality of Life index (DQL) will be assessed in both groups. It is believed that the new machine will provide better overall outcomes compared to the traditional machine.

A Prospective cohort study of 25 COPD patients with osteoarthritis undergoing an exercise plan in a pulmonary rehab program. Patient pain level, clinical outcomes, and ultimately, quality of life outcomes will be assessed in order to assess whether future compliance for COPD arthritic patients will occur in an exercise rehabilitation program.

Inclusion Criteria:

• COPD Patient
• Osteoarthritic limitations in upper or lower extremities, or spine
• Forced Expiratory Volume (FEV)1 less than 70%
• Forced Expiratory Volume/Forced Vital Capacity (FEV/FVC) ratio less than 70%

Exclusion Criteria:

• Patients with rheumatoid arthritis

A cohort of 25 COPD patients (total N = 50) with osteoarthritis undergoing an exercise plan in a pulmonary rehab program.
