Assessment
Primary outcomes Primary outcomes were a change in the muscle cross-sectional area and muscle thickness from baseline to after 2 weeks, as measured using real-time B-mode ultrasonography with a 50mm 8MHz linear probe. During the ultrasonography, the participants were in a supine position with their knees extended at 0 degree and muscles relaxed. Four ultrasonography images were recorded at 50% on the line from the anterior superior iliac spine to the upper region of the patella of rectus femoris, vastus lateralis and vastus intermedius, and at 80% on the line between the anterior superior iliac spine and the joint space in front of the anterior border of the medial ligament of vastus medialis. Muscle thickness was calculated as the length between the deep aponeurosis and surface aponeurosis at 3 different points in the image. The mean thickness was calculated in each ultrasonography image.
Key secondary outcomes Secondary outcomes included changes in physical function from day 2 after admission to the ICU and after being on a ventilator for more 2 days, to after 2 weeks as well as the health care cost and, health-related quality of life.

Quadriceps muscle strength: Isometric muscle strength of the quadriceps muscle was measured at the time of discharge from the hospital using a hand-held dynamometer . Patients sat with their hips and kneespositioned at 90 degree of flexion, and their arms folded across their chests. A sensor of the hand held dynamometer was attached to the lateral malleolus axis at the front of the lower leg. We instructed the patients to contract the quadriceps muscle "as hard and fast as possible" during the isometric quadriceps muscle contraction test. The test was repeated twice and a maximum knee extensor contraction of 5 seconds was performed with 2 minutes of rest between each test. The largest maximal volitional isometric knee extensor strength data was recorded as the absolute value.
Grip strength: Grip strength was measured on day 2 after admission to the ICU and after 2 weeks using a hand-held dynamometer. Patients lay with their elbow positioned at 90 degree of flexion. The test was repeated twice, and a maximum grip contraction of 3 seconds was performed with 2 minutes of rest between each test.

Interventions/Control_1 ICU patients received traditional physical therapy and Hybrid EMS, which began within 48 hours of admission and continued daily for 2 weeks until discharge from ICU. The Hybrid EMS intervention involved an automatic cycle ergometer attached to a belt electrode skeletal muscle stimulator (Homer Ion Co. Ltd, Tokyo, Japan). The automatic cycle ergometer (Escargot, PBE100) was set at 40 to 50 revolutions per min. The quadriceps femoris, hamstrings, tibialis anterior muscle, and triceps surae were stimulated for Hybrid EMS in this study. The stimulator current waveform was used for exponential climbing pulse to reduce discomfort during muscle stimulation, and designed to produce co contractions in the lower extremity muscle groups at a frequency of 20 Hz with a pulse duration of 250 micro second. Stimulation intensity was increased until muscle contraction was observed or palpable to a maximum of 130 to 230 mA, without causing discomfort. The duty cycle was a 3s stimulation with a 3s pause for a period of 20 min. We used safety guidelines of exercise to determine if exercise training was unsafe to commence or should be ceased. The Hybrid EMS program was conducted 7 days per week, and each session consisted of 1 or 2 sets of 20 min.
Interventions/Control_2 The control group received traditional physical therapy consisting of early mobilization (range of motion exercise, upper and lower extremity exercise, ambulation, sitting on the edge of the bed, standing, sit to stand, and functional and activity of daily living exercise) for 20 to 60 min perday, for 5 to 7 days per week, until the patient was discharged from the hospital.
