ESS–epidural spinal stimulation; TSS–transcutaneous spinal stimulation.two.2. Information Acquisition Surface electromyogram (EMG) signals had been recorded utilizing bipolar self-adhesive electrodes placed longitudinally more than the muscle belly of the vastus lateralis (VL), medial hamstrings (MH), tibialis anterior (TA), and soleus (SOL) muscle tissues of every leg. Signals had been differentially amplified and digitized at a sampling price of 4000 samples per second (PowerLab, ADInstruments, Dunedin, New Zealand) and stored electronically (LabChart, ADInstruments, Dunedin, New Zealand). EMG information were analyzed offline employing custom code written in MATLAB (Version R2020a, The Mathworks Inc., Natick, MA, USA) following application of a notch filter at 60 Hz as well as a 2nd order bandpass filter among 10 and 1000 Hz. All EMG recordings have been synchronized to each and every pulse of TSS or ESS through stimulus artifact recorded from an electrode placed on the surface on the thoracolumbar spine. Study participants had been instructed to execute two experimental tasks with and with no spinal stimulation: (1) to stay relaxed although lying supine to establish a manage condition, and (2) to place forth maximum effort in attempting a single leg flexion maneuver including hip flexion, knee flexion, and ankle dorsiflexion simultaneously. A subset of subjects was also asked to execute joint-specific movements (e.g., plantarflexion, dorsiflexion) in the presence of stimulation. Each job was performed for a minimum of three trials in every leg by every single participant. During voluntary tasks, stimulation was delivered at a worldwide motor threshold, which was defined because the stimulation amplitude where the peak-to-peak amplitude of all recorded muscles exceeded 20 responses. two.3. Stimulation Procedures Transcutaneous spinal stimulation was delivered either making use of a DS7A Biphasic Continuous Present Stimulator (Digitimer, Hertfordshire, UK) or perhaps a custom-built, three channel constant-current stimulator. Stimulation was administered by means of self-adhesive electrodes (PALS, Axelgaard Manufacturing Co., Ltd., Fallbrook, CA, USA) using a diameter of 3.two cm placed around the skin at the spinal midline involving spinous processes from the T11 to L2 vertebrae to act as cathodes. Two five cm 10 cm self-adhesive electrodes (PALS, Axelgaard Manufacturing Co., Ltd., Fallbrook, CA, USA) have been placed symmetrically on the skin longitudinally over the abdomen for use as anodes. Throughout TSS, stimuli had been delivered as monophasic rectangular pulses having a 1 ms pulse width. Stimuli have been delivered at 050 mA at stimulation frequencies among 0.two and two Hz. A minimum of 3 stimuli have been delivered throughout each and every trial. Epidural spinal stimulation (ESS) was delivered working with an implantable spinal cord stimulator (Specify 5-6-5, Medtronic, Fridley, MN, USA) placed amongst the T11-L1 vertebral bodies connected to an implanted pulse generator (RestoreSensor Sure-Scan MRI, Medtronic, Fridley, MN, USA). Through ESS, stimuli had been delivered as biphasic chargebalanced rectangular pulses with a 0.21 ms pulse width at a frequency of 0.two Hz. Every single electrode.
