Effects of Different Inspiratory Muscle Training Protocols in Hematopoietic Stem Cell Transplant Recipients

Inspiratory muscle training will be performed at 40% of MIP workload, 1 set of 8-10 diaphragmatic respirations for 15 minutes, with 5-10 seconds rest intervals between sets. 5 days a week, 2 sessions per day.

This study investigates the integration of functional inspiratory muscle training (IMT) with conventional physiotherapy. Patients will perform inspiratory muscle training using the threshold loading technique with the POWERbreathe IMT device, combined with functional exercises. The functional IMT protocol will be administered face-to-face, 3 days a week, for 30 minutes per session over a 6-week period. Resistance on the IMT device will be set to 40% of the patient's maximal inspiratory pressure (MIP) and adjusted weekly based on measured MIP values. Exercises will be categorized into three progressive difficulty levels (easy, medium, and hard), with each stage lasting 2 weeks. Patients will inhale through the POWERbreathe IMT device during exercise movements and exhale during the return phase, ensuring simultaneous respiratory muscle activation and functional training.

Control group will be performed at 10% of the MIP workload, 1 set of 8-10 diaphragmatic breaths for 15 minutes, with 5-10 seconds rest intervals between sets. 2 sessions per day, 5 days a week.
