Title : Efficacy of Inspiratory Muscle Training (IMT) in post-weaning ICU recovery: A clinical randomized controlled trial
Abstract:
This study addressed a critical gap in ICU rehabilitation by investigating the efficacy of Inspiratory Muscle Training (IMT) for patients who have been weaned from mechanical ventilation but continue to suffer from respiratory muscle weakness. The goal was to determine if targeted, progressive IMT could effectively rebuild diaphragmatic strength and improve overall functional recovery.
Key Findings:
- IMT led to significant structural and functional improvements in the diaphragm, with measured increases in both thickness (+158%) and motion (+33%).
- Patients in the IMT group showed markedly greater improvements in quality of life (SF-36 score) compared to the standard care group.
- Ultrasound proved to be a crucial tool, providing objective, non-invasive data to visually confirm muscle recovery where traditional volitional tests may be limited.
- IMT was found to be a feasible and well-tolerated adjunct therapy in the post-ICU setting.
Supporting Illustrations:
The poster will feature key graphics, including:
- Bar charts comparing diaphragm thickness and motion pre- and post-intervention.
- A line graph showing the trend in SF-36 quality of life scores over time for both groups.
- A flow diagram of the study methodology.
Effects and Impacts: This research provides strong evidence that IMT is an effective intervention for mitigating diaphragmatic atrophy and weakness in post-ICU patients. Its findings advocate for the integration of structured IMT protocols into standard rehabilitation practices to improve weaning outcomes, reduce patient disability, and enhance long-term recovery. The use of ultrasound offers clinicians a reliable method to objectively assess and monitor patient progress. Supports IMT as an effective adjunct treatment to rebuild diaphragm strength and enhance recovery in weaned ICU patients.
