Effects of Inspiratory Muscle Training (IMT) on Balance Ability and Quality of Life of Diabetes Mellitus Patients

Participants will perform home-based IMT twice daily \[once in the morning (between 7:00 and 12:00 am) and once in the evening (between 16:00 and 21:00 pm)\], for 8 consecutive weeks, using a mechanical pressure threshold loading device. In addition, participants in this group will try to increase the inspiratory resistance when the participants feel that 30 breaths are achievable with ease or if the participants could reach 35 consecutive breaths.

Participants will perform 60 slow breaths once daily at a load setting of 0 (corresponding to \~15% \[baseline\] MIP), using the same device as the IMT group. For the sham group, the ability to adjust the training load will be prevented using sticky tape applied to the device's load adjuster.
