In coloproctology centers, EMG of external sphincter and pelvic floor muscles is often required.

Portable EMG and NCS system Neuro-MEP-Micro packed with the necessary techniques is the right solution for these needs.

Specific techniques for neurophysiological assessment of external sphincter and other pelvic floor neuromuscular structures

The system is used to perform various neurophysiological examinations of pelvic floor for diagnostic and scientific purposes, i.e.:

  • bulbocavernosus  and other sacral reflex tests with electrical stimulation of pudendal nerve to assess the conduction of reflex arcs (S2-S4);
  • surface EMG of external sphincter and pelvic floor muscles to assess the level of tonic contraction;
  • needle EMG with quantitative motor unit potential (MUP) analysis coupled with sacral reflex test to detect sacral denervation;
  • stimulation EMG used  with a disposable St. Mark’s electrode to stimulate the distal part of pudendal nerve;
  • pudendal nerve somatosensory evoked potentials (pSEPs) especially in patients with preserved sacral reflexes and hypoesthesia of perineum;
  • sympathetic skin responses (SSR) recorded from perineal area to assess the conduction velocity of sympathetic unmyelinated fibers and myelinated sensory nerve fibers;
  • analysis of motor evoked potentials (MEP) in perineal muscles during the cortical and sacral magnetic stimulation (the assessment of corticospinal tract conduction with recording of pelvic floor motor evoked potentials (if the magnetic stimulator is available)).

Portable design

Neuro-MEP-Micro requires very little space and is connected to a computer via the USB cable which ensures data uploading and power supply of the device. If not powered from mains, the device can operate from the notebook battery.

Electrical stimulator with two outputs

Two software switchable outputs to plug in the electrical stimulator allow a specialist to place two pairs of stimulating electrodes on a patient and connect them to the device. Thus, there is no need to switch the electrodes as the stimulating electrode is software-defined.

In 2011, I purchased the first Evidence 3102* from Schreiber&Tholen**, Germany, for my research lab dealing with disease models of peripheral neuropathies, myasthenic syndromes, and of myelopathies in mice and rats. The run-in period was very short because the programs are user-friendly, dependable and adaptable to the special needs in small rodents, the youngest being 8 days old. No EMG machine I ever used before was as powerful as this one. On numerous trips to collaborating labs in the US, Germany and Switzerland I carried this equipment with me. Meanwhile 6 completely established sets are working in most of these collaborating labs. There was no failure ever of the Neurosoft hardware, and in case of minor software problems Schreiber&Tholen provided swift and concise help through the Internet around the globe if needed — again with no precedence in my career in clinical electrophysiology. Even in lab facilities without perfect electromagnetic shielding little if any problems occurred. I highly recommend this equipment to anyone interested in doing clinical neurophysiology in animal models of neurologic disorders.

I have been using Neurosoft Neuro-MEP-Micro device since 2010 and I have never abandoned the choice of excellent quality of Neurosoft electromyography devices. I am following with interest the evolution of new portable 3- and 5-channel devices, always with the fantastic philosophy of USB power supply.

Neurosoft really gives you a lot from both the hardware and software points of view, excellent signal quality, trace analysis with many options, reliability.

Working mainly in Italy, a note of merit goes to the distributor providing technical assistance in the country (TAOMED s.r.l.).
