What this Trial Is About
Researchers are evaluating the effects of core stabilization exercises combined with functional inspiratory muscle training (IMT) on physiological and psychological health in people with post-COVID-19 syndrome. This trial focuses on respiratory muscle strength and trunk endurance as primary outcomes. Participants diagnosed with post-COVID-19 syndrome, aged 18 to 65 years, and classified as level 2-3 on the Post-COVID-19 Functional Status Scale (PCFS) will take part in this study. Participants will be randomly assigned to one of two groups. One group will undergo a 12-week core stabilization exercise program with sessions three times a week, each lasting about 45 to 50 minutes. The other group will receive the same core stabilization program plus functional IMT using a portable device set at 60% of maximal inspiratory pressure, with training intensity progressively increased over the 12 weeks. Throughout the study, participants will undergo comprehensive assessments before and after the intervention. These include tests of respiratory and peripheral muscle strength, trunk muscle endurance, balance, exercise capacity, as well as evaluations of anxiety, depression, fatigue, and quality of life. Measurements will include maximal inspiratory/expiratory pressure tests, Functional Movement Screen, endurance tests like plank and Sorenson, handgrip strength, body composition, and quality of life questionnaires. The study aims to monitor changes over 12 weeks and assess patient satisfaction and improvement.
