Comparison of Londrina activities of daily living protocol and Glittre ADL test on cardio-pulmonary response in patients with COPD: a cross-sectional study
Background: In COPD patients it is very important to assess the activities of daily living (ADL) due to an impairment of independence and quality of life. There is a lack of retrievable data regarding the cardio-pulmonary response to Londrina ADL protocol in patients with COPD. The aim of the present study was to assess the cardio-pulmonary response to Londrina ADL protocol in patients with COPD and to compare this with responses to the Glittre ADL test.
Methods: This cross-sectional study was done on 30 COPD subjects. Each subject was made to perform the Londrina ADL protocol, Glittre ADL test, twice each, on subsequent days. The Londrina ADL protocol comprises 5 activities representing ADL, involving upper limbs, lower limbs, and trunk movements. The Glittre ADL test consists of completing a circuit while carrying a weighted backpack (2.5 kg for women, 5.0 kg for men). The better value of the two was taken into consideration. For the Londrina ADL protocol and Glittre ADL test the outcome of primary interest was time and for the six-minute walk test was the distance walked. The secondary outcomes for all the tests were heart rate, systolic blood pressure, diastolic blood pressure, respiratory rate, saturation of oxygen in blood and dyspnea.
Results: The COPD subjects of age group 63.27±11.07 years took 5.94±0.36 min to complete trial 2 of the Londrina ADL protocol. A significant physiological increase in heart rate (p≤0.01), respiratory rate (p≤0.01), blood pressure (p≤0.01) and severity of dyspnea (p≤0.01) were observed whereas saturation of oxygen in blood (p≤0.01) was reduced at the end of the Londrina ADL protocol and Glittre ADL test. There was a positive, non-significant correlation between the six-minute walk test distance and the Londrina ADL protocol time (r=0.236) (p=0.209). A positive, not significant correlation was observed between the Glittre ADL test (time) and the Londrina ADL protocol (time) (r=0.194) (p=0.304) and a negative but not significant correlation between the six-minute walk test (distance) and the Glittre ADL test (time) (r= -0.184) (p=0.330).
Conclusion: The Londrina ADL protocol can be used as an assessment tool to the evaluation of functional performance and activities of daily living in COPD along with other test protocols in pulmonary rehabilitation.
