Neurosciences-Intensive Care Unit Electrical Stimulation

"An Intelect Neuromuscular Electrical Stimulator (NMES) (Chattanooga Group) device will be used to provide the stimulation. The stimulator will be set up and taken off the patients by a member of the study team or a trained ICU staff member. The stimulation parameters will be as follows:~Electrode location: Proximal and distal quadriceps Waveform: pulsed biphasic Pulse duration: 300 microseconds Pulse frequency: 35 pulses per second Amplitude: palpable, visible quadriceps muscle contraction On/off time: 5 seconds on, 15 seconds off Ramp up and down time: 2 seconds each"

"If a muscle contraction is not produced with the Intelect NMES portable device, the Vectra Neo Clinical Therapy System (Chattanooga Group) device will be used instead. The stimulator will be set up and taken off the patients by a member of the study team or a trained ICU staff member. The stimulation parameters will be as follows:~Electrode location: Proximal and distal quadriceps Waveform: pulsed biphasic Pulse duration: 300 microseconds Pulse frequency: 35 pulses per second Amplitude: palpable, visible quadriceps muscle contraction On/off time: 10 seconds on, 30 seconds off Ramp up and down time: 2 seconds each"
