Abstract
Background and purpose: To examine the respiratory and functional benefits of manual diaphragmatic release for Cleaning-Laborers Exposed to Occupational Hazards.
Methods: A randomized controlled trial of 36 participants aged 35-45 years was randomly allocated into two groups. The experimental group (n = 18); received manual diaphragm release along with respiratory training exercises, and the control group (n = 18); received respiratory training exercises only. Three times/week for 12 consecutive weeks. The serum immunoglobulin E level, pulmonary functions [forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC, and peak expiratory flow (PEF) rate (PEF)], chest wall mobility, and 6 min walk-test performance were assessed pre- and post-intervention.
Results: There was a greater decline in serum immunoglobulin levels (p = 0.003; Partial η2 = 0.23) and enhancement in pulmonary functions [FEV1 (p = 0.025, Partial η2 = 0.14), FVC (p = 0.017, Partial η2 = 0.16), FEV1/FVC (p = 0.028, Partial η2 = 0.13), and PEF (p = 0.012, Partial η2 = 0.17) in the experimental group. Further, there was a greater increase in chest mobility at the xiphoid level (p = 0.002, Partial η2 = 0.25) in the experimental group, but this was not the case at the axillary level (p = 0.29, Partial η2 = 0.03). Still, the 6 min walk-test performance improved more significantly in the experimental group (p = 0.002, Partial η2 = 0.24).
Conclusion: The diaphragmatic release technique may offer a promising approach for mitigating distressing respiratory symptoms, enhancing immune function, and improving 6 min walk-test performance among cleaning laborers with work-related respiratory hazards.
Trial registration: The study was retrospectively registered at XXX (ID: NCT05802355).
期刊介绍:
Physiotherapy Research International is an international peer reviewed journal dedicated to the exchange of knowledge that is directly relevant to specialist areas of physiotherapy theory, practice, and research. Our aim is to promote a high level of scholarship and build on the current evidence base to inform the advancement of the physiotherapy profession. We publish original research on a wide range of topics e.g. Primary research testing new physiotherapy treatments; methodological research; measurement and outcome research and qualitative research of interest to researchers, clinicians and educators. Further, we aim to publish high quality papers that represent the range of cultures and settings where physiotherapy services are delivered. We attract a wide readership from physiotherapists and others working in diverse clinical and academic settings. We aim to promote an international debate amongst the profession about current best evidence based practice. Papers are directed primarily towards the physiotherapy profession, but can be relevant to a wide range of professional groups. The growth of interdisciplinary research is also key to our aims and scope, and we encourage relevant submissions from other professional groups. The journal actively encourages submissions which utilise a breadth of different methodologies and research designs to facilitate addressing key questions related to the physiotherapy practice. PRI seeks to encourage good quality topical debates on a range of relevant issues and promote critical reflection on decision making and implementation of physiotherapy interventions.
