Upper abdominal surgical treatment may have reduced respiratory muscle function and mucociliary clearance, which might be a consequence of postoperative pulmonary complications (PPCs). The threshold inspiratory muscle training (IMT) may serve as an effective modality to improve respiratory muscle strength and endurance in patients. However, whether this training could help patients with upper abdominal surgery remain to be determined.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention group | Experimental | We conducted a fully engaged inspiratory muscle training (IMT) program. The exercise group received the intervention threshold IMT from preoperative to postoperative undergoing upper abdominal surgery. The IMT was started before 3 weeks of operation and surveyed in the followed 4 weeks. |
|
| Usual care group | Active Comparator | The Usual care group will receive regulated education. |

|---|---|---|---|---|
| Inspiratory muscle training | Behavioral | The initial training intensity of the preoperative threshold IMT trainer (DofinTM, Breathing Strength Builder, Taiwan) was moderate to high intensity (≥50% of MIP), which was according to the patient's baseline level and increased by 5-10% per week. The frequency is 25-30 minutes each time, twice a day and five days per week for at least two weeks. The participants would receive at least 10 times training sessions before surgery |

| Postoperative Pulmonary complications rate | According to the definition of PPCs on European Perioperative Clinical Outcome 2015 | Change from baseline (0 week) to follow up (4 weeks) |
| Respiratory muscles strength | MIP and MEP are done by measuring the upper airway pressure | Change from baseline (0 week) to follow up (4 weeks) |
| Diaphragm mobilit | Diaphragm ultrasonography | Change from baseline (0 week) to follow up (4 weeks) |
