The Effects of the Otago Exercise Program

The objective of this experimental study is to conduct a comparative evaluation of the effects of a supervised Otago Exercise Program (OEP) functional exercise capacity, blood lactate levels, dyspnea, fatigue, peripheral muscle strength, functional mobility, balance performance, quality of life, sleep status, and comorbidities in adults with pulmonary arterial hypertension (PAH) associated with congenital heart disease (CHD), as compared to a control group. The primary questions driving our study are: * Does the Otago Exercise Program contribute to an increase in functional capacity? * Does the Otago Exercise Program have positive effects on blood lactate levels, dyspnea, fatigue, peripheral muscle strength, functional mobility, balance performance, quality of life, sleep status, and comorbidities? The study participants will be randomly allocated into two groups (n = 50) using a randomized controlled design. The training group (n = 25) will undergo the Otago exercise program, supervised by a physiotherapist, conducted three days a week within a hospital setting for an 8-week intervention period. Following the initial assessment, a patient education session will be administered for the control group (n = 25) and all participants, providing information on disease pathophysiology and the benefits of physical activity. Evaluations will be conducted at baseline and post the 8-week intervention period. Our research project is designed to investigate the effectiveness of the supervised OEP in adults with CHD associated with PAH. Researchers will compare the training and control groups to determine the effects on functional capacity, blood lactate levels, dyspnea, fatigue, peripheral muscle strength, functional mobility, balance performance, quality of life, sleep status, and comorbidities.
