Clinical Utility of Diaphragmatic Ultrasound in Chronic Obstructive Pulmonary Disease Patients Undergoing Rehabilitation

Abstract

Background: Pulmonary rehabilitation (PR) is a well-recognized intervention in the management of individuals with chronic obstructive pulmonary disease (COPD) that is designed to improve patients’ physical and psychosocial conditions. The primary aim of the study was to determine the effect of PR on ultrasonography (USG) assessment of diaphragmatic excursion. Materials and Methods: The current study is a prospective, interventional study in COPD (Group D) patients. All subjects underwent 8 weeks of supervised PR. The baseline assessment with USG diaphragmatic excursion, quadriceps femoris (QF) thickness, biceps brachii (BB) thickness, mid-thigh circumference, mid-arm circumference, modified Medical Research Council score, 6-min walk distance, COPD assessment test score, and after 8 weeks of supervised rehabilitation same parameters observed. Results: About 25.71% of the study population was in the age group range of 45–55 years, 51.43% between 56 and 65 years and 22.86% within 66–75 years of the age group. Out of 35 patients, 15 (42.86%) were females and the rest 20 (57.14%) were males. A significant increase was found in the diaphragmatic excursion (cm) from (P < 0.0001), mid-arm circumference (cm) (P < 0.0001), BB thickness (cm) (P < 0.0001) (upper limb strength and endurance training), and mid-thigh circumference (cm) (P < 0.0001) along with QF thickness (cm) (P < 0.0001) (lower limb strength and endurance training). Conclusion: An 8-week physical and PR program in COPD patients can lead to an improved USG diaphragmatic excursion.
