The effectiveness of early neuromuscular electrical stimulation in patients after acute aortic dissection surgery

INTERVENTION: Postoperative mobilization and exercise program and neuromuscular electrical stimulation. Neuromuscular electrical stimulation: implemented on the bilateral quadriceps, hamstrings, triceps surae, tibial anterior muscles using belt electrode for 20 minutes per day from postoperative day 1 to 7. Postoperative mobilization and exercise program and neuromuscular electrical stimulation. Neuromuscular electrical stimulation: implemented on the bilateral quadriceps muscle but intensity is not cause muscle contraction for 20 minutes per day from postoperative day 1 to 7. CONDITION: Adult patient with Stanford type A acute aortic dissection undergoing emergency surgery PRIMARY OUTCOME: The change ratio of muscle thickness of rectus femoris, vastus intermedius, and quadriceps femoris at postoperative day 7 and 14. SECONDARY OUTCOME: Handgrip strength Usual gait speed Days until 100 m walking Home discharge INCLUSION CRITERIA:
