Effect of Transauricular Vagal Stimulation on Cardiac Function After Spinal Cord Injury

Active taVNS application was performed by stimulating a sterile acupuncture needle (0.25x25 mm) placed on the left ear cymba choncae with a stimulator. Active taVNS group received for 10 days, 30 minutes with a current intensity of 1 mA, pulse width of 200 µs, frequency of 25 Hz and biphasic sinusoidal waveform. In the sham group, stimulation was applied to the lobulus auriculae of the left ear (which is not innervated by the vagus nerve) using the same current intensity and duration as the active group.
