Occupational workers are at heath risk due to exposure to silica dust which is presence in construction and manufacturing sectors, masonry works, as well in mining sector. A comparative study was done to determine the Effectiveness of pulmonary rehabilitation on physiological and biochemical parameters among workers occupationally exposed to silica.
Design: A true experimental research design was used for this study.
Materials and methods: Occupational workers who are exposure to silica and working in cement factories.Who fulfills the inclusion criteria, sample size was ((n=160) divided in control group (n=80) , experimental group (n=80). Pre test was conducted to control and experimental group. Pulmonary parameters, base line clinical variables, spirometry to check the pulmonary function,6MWT stress tolerance test, HB,ESR,RBS blood investigtions, pranayama (yoga) and nutritional education was done for Experimental group.Supervised pulmonary rehabilitation was carried out and post test was done after 12 weeks, 18weeks and 24 weeks. The results were analyzed by descriptive and inferential statistical methods using SPSS statistical package (Systat software inc. San Jose, USA).
Conclusion: Pranayama and nutritional education showed significant improvement in lung capacity and pulmonary functions, SGRQ shows experimental pre and post statistically significance (p=<0.001).
