Effects of Home-based Respiratory Muscle Training With New Load Adjustment Test in People With Multiple Sclerosis

It is a single-blind randomized clinical trial study. Each participant will be randomly assigned to one of the following groups: 1) Inspiratory muscle training + Expiratory muscle training with load adjustment based on the principles of the 1-repetition maximum (RM) test , 2) Inspiratory muscle training + Expiratory muscle training with convetional load adjustment. Each exercise training program will be applied twice (morning inspiratory muscle training session and evening expiratory muscle training session) per day 5 sessions per week during 8 weeks by a threshold device. The sessions will be supervised by a physiotherapist through a virtual platform. Participants received baseline assessments at the beginning of the intervention, at the end of the 4th week (only the group 2), and post-intervention assessments at the end of the 8th week.
