inspiratory muscle training and expiratory muscle thickness

Conditions: Intensive Care Unit Syndrome; Muscle Weakness; Rehabilitation

Summary: the specific effect of imt on expiratory muscle strength and abdominal wall thickness during weaning remains unclear. to address this significant research gap, the primary objective of our study was to evaluate the effect of imt after extubation on expiratory muscle strength and abdominal muscle thickness in respiratory icu patients. on the other hand the investigators established reference values for ultrasonographic measurements in healthy control subjects as a comparative arm. to the best of our knowledge, this is the first study to examine the ultrasonographic effects of imt on the expiratory muscle thickness after extubation. the investigators believe that our study may contribute to related literature in this context and guide future research as a pioneer with its unique value.
