Brief Summary:

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.

Arm Intervention/treatment
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.
Device: EMS
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.

Primary Outcome Measures :
  1. ventilator-free days [ Time Frame: 28 days ]
    the number of days between successful weaning from mechanical ventilation and day 28 after study enrollment

Secondary Outcome Measures :
  1. Grip power [ Time Frame: 7 days ]
    Weekly improvement of both hand grip muscle power in kilogram(Kg)
