The number of studies examining the effects of exercise training in pulmonary hypertension (PH) is limited in the literature. Given the chronic nature of PH and the benefits of exercise in PH, the importance of exercise programs that include motivation as a factor becomes apparent. Therefore, the aim of this research is to investigate the effectiveness of exercise programs implemented via virtual reality under the supervision of a physiotherapist in PH patients. To investigators' knowledge, there are no studies in the literature examining the effectiveness of exercise training conducted via virtual reality in PH patients. Therefore, another aim of this research is to identify virtual reality (VR) applications that can be used to improve clinical outcomes in PH patients and to contribute to the literature on the effectiveness of using innovative technologies in rehabilitation programs.
