Meta-analysis on the effects of exercise training-based respiratory rehabilitation therapy in pneumoconiosis patients
Objective To comprehensively analyze the effectiveness of exercise training-based respiratory rehabilitation therapy on patients with occupational pneumoconiosis(hereinafter referred to as"pneumoconiosis").Methods Literature on randomized controlled trials of exercise training-based respiratory rehabilitation therapy for pneumoconiosis patients published from the establishment of the database to July 2023 was retrieved from academic systems such as the China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,VIP Database,and China Biology Medicine using bibliometrics method.The RevMan 5.4 software was used for meta-analysis of the selected literatures.Subgroup analysis was conducted to explore the source of study heterogeneity.The funnel plot method was used to test publication bias.Results A total of 55 articles were included,involving 2 436 pneumoconiosis patients in the experimental group and 2 405 pneumoconiosis patients in the control group.The result of random or fixed effect model showed that the six minutes walking distance,the total score of Short from Health Survey-36,forced vital capacity(FVC),forced expiratory volume in one second(FEV1),FEV1/FVC,arterial partial pressure of oxygen of pneumoconiosis patients increased after respiratory rehabilitation therapy(all P<0.05),while the total score of the St.George's Respiratory Questionnaire and arterial partial pressure of carbon dioxide decreased compared with the conventional treatment(all P<0.05).The result of subgroup analysis showed that the total score of the St.George's Respiratory Questionnaire,FEV1,and the index of arterial partial pressure of oxygen of pneumoconiosis patients was better in the rehabilitation treatment for ≥six months compared with those<six months(all P<0.01).The funnel plot result showed that no obvious publication bias.Conclusion Exercise training-based respiratory rehabilitation therapy can improve the quality of life,exercise endurance,respiratory function,and arterial blood gas levels of patients with pneumoconiosis.
