Evaluation of the Level of Physical Activity and Muscle Strength of Quadriceps in Patients Hospitalized for E-COPD: A Longitudinal Study

The objectives of the present study were to assess the level of physical activity in daily life (PADL) and isometric muscle strength of the quadriceps in patients hospitalized for exacerbation of COPD and to verify changes after 3 months of hospital discharge. This is a longitudinal observational study that assessed the PADL level with an accelerometer, after 24 h of the hospitalization and the beginning of the drug treatment and assessed the quadriceps muscle strength with a manual dynamometer, after 72 h of hospitalization, in 32 patients with COPD (66 ± 7.61 years), in addition to repeating both assessments with 30 days of hospital discharge and after 3 months of follow-up. Cognition, dyspnea, general health, physical performance and lung function were assessed to characterize the sample. As main results, there was increase in active time (344 ± 260 - 447 ± 199 min; p = 0.04) and number of steps (4.241 ± 374 - 6.216 ± 400 steps; p = 0.02) after three months. In addition, inactive time showed significant reduction 30 days after hospital discharge (1.151 ± 249 - 1.065 ± 198 min; p = 0.02). The level of physical activity showed significant improvement due to the increase in active time and number of steps after three months of hospital discharge and to the reduction of inactive time 30 days after hospital discharge.PMID:34424805 | DOI:10.1080/15412555.2021.1967914
