Electric Muscle Stimulation for Patients With Chronic Respiratory Failure
Background: After mechanical ventilation, 5-20% of patients with acute respiratory failure would depend on ventilator support more than 14 days because of critical-illness weakness and their underlying diseases such as heart failure and chronic obstructive pulmonary disease.
Hypothesis: Electric muscle stimulation(EMS) will improve their muscle strength and shorten their ventilator days.
Design: Randomized controlled trial. Adult patients with mechanical ventilation more than 14 days are eligible. EMS would be applied in experimental group 32 minutes/day on their bilateral thigh.
|Study Design:||Allocation: Randomized

|Official Title:||Effect of Electric Muscle Stimulation on Patients With Chronic Respiratory Failure|
- ventilator-free days [ Time Frame: 28 days ]the number of days between successful weaning from mechanical ventilation and day 28 after study enrollment
- Grip power [ Time Frame: 7 days ]Weekly improvement of both hand grip muscle power in kilogram(Kg)
|Study Start Date:||August 2013|
|Estimated Study Completion Date:||June 2017|
|Estimated Primary Completion Date:||June 2017 (Final data collection date for primary outcome measure)|
Experimental: Electric muscle stimulation(EMS)
EMS:use programmed middle frequency electric stimulation device(HELEX 573)for both quadriceps stimulation, 32 minutes per day, 5 time per week.
HELEX 573 : strength aggravation mode with middle frequency carrier(1500Hz), minimal voltage for visible muscle contraction(maximum output is 75mA) , 32 minutes per day.
No Intervention: Control
Patients with routine passive rehabilitation program.
