Study: NCT03662555

Intervention type: DEVICE
Group type: ACTIVE_COMPARATOR
Intervention: Neuromuscular electrical stimulation
Description: Neuromuscular electrical simulation (NMES) Two self-adhesive electrodes (2 mm thick) will be placed over the rectus femoris, vastus medialis and vastus lateralis muscles. The electrodes will be placed on the motor points of each muscle. The stimulator discharges biphasic rectangular pulses. The stimulation frequency and duty cycle will be 50 Hz and 5 s of stimulation followed by a 5 s pause for each rep. The intensity of electrical flow will be at each subject's maximum that they can tolerate. The stimulation will be for 5 x 5 min sets with 1 min rest between sets.~Blood flow restriction~A handheld Doppler probe (Hi-Dop) will detect their auscultatory and visual pulse using the doppler's screen. The cuff will be inflated initially up to their systolic blood pressure and then incrementally by 10 mmHg until no auscultatory or visual pulse is detected. A percentage of 40% or 80% of each subject's LOP will then be used during the BFR conditions.
