Background: COPD is a crippling and progressive respiratory condition that frequently causes considerable muscular atrophy, especially in the quadriceps. Weakness in the quadriceps has been associated with decreased muscle strength which may result in poor quality of life, and a rise in reduced mobility due to the risk of fractures and falls in COPD patients.
Methods: Thirty-five patients diagnosed with COPD irrespective of gender, over the age of 45 and less than 60 years were recruited for the study. Patients were divided into control and experimental groups and exposed to five weeks of guided quadriceps muscle-strengthening exercises. VMO (Vastus Medialis Oblique) exercises and progression exercises were added to static and dynamic quadriceps exercises for the experimental group. Pre-test and post-test quadriceps muscle strength were assessed using a 6-min walk distance (6MWD), one-repetition maximum (1RM) and Manual muscle testing (MMT). Data were analyzed using SPSS software.
Results: Mean age of male COPD patients was 56 and 54.5 years respectively for the control and experimental groups. There was a statistically significant improvement in quadriceps muscle strength of the experimental group was noted by analyzing 1RM and MMT test data. 6MWD test results showed statistically significant improvement in quadriceps muscle capability to walk for the experimental group. Hence an improvement in daily living activities was considered as a result of engaging VOM and progression exercises in the conventional physiotherapy exercise program.

Conclusion: Quadriceps strengthening exercises are effective in improving pain , function , and quality of life in patients with COPD.
