Finding proper care for neurological conditions can be tricky at times. You need a combination expertise along with advanced technology, infrastructure and medicines. We ensure that every person who approaches IONM receives, exactly the same.
Real-Time Neural Protection for High-Risk Surgery
At SIMS Hospitals, the Institute of Intraoperative Neurophysiological Monitoring (IONM) & Clinical Neurophysiology is one among the few physician-led neurophysiology programmes in India. Our specialised team of experts annually handle more than 300 high-risk surgeries, supported with real-time neurophysiological protection.
The institute is dedicated to protecting brain, spinal cord, peripheral nerves, and critical neural pathways during complex surgical procedures through advanced neurophysiological monitoring, functional mapping, and continuous intraoperative decision support. We rely on patient centric approach starting from your first appointment till the end of your recovery journey.
At IONM, we cover all the comprehensive neurophysiology services under one roof including:
A full suite of Modalities include Motor Evoked Potentials (MEPs), Somatosensory Evoked Potentials (SSEPs), Continuous and Triggered EMG, D-wave monitoring, EEG, Electrocorticography (ECoG), cranial nerve monitoring, pedicle screw testing, nerve root and proximity testing, Brainstem Auditory Evoked Responses (BAERs), bulbocavernosus reflex monitoring, laryngeal adductor reflex monitoring, and advanced cortical and subcortical mapping.
Comprehensive outpatient neurodiagnostic services for neuropathies, myopathies, and neuromuscular junction disorders, including Single Fibre EMG (SFEMG), Autonomic Function Testing (AFT), Nerve Conduction Studies (NCS), Electromyography (EMG), and Evoked Potentials including Visual Evoked Potentials (VEP), SSEPs, and Brainstem Auditory Evoked Potentials (BAEP).
Advanced monitoring for complex surgical scenarios including cortico-bulbar MEPs (CoMEPs) for facial nerve assessment, extraocular muscle monitoring in skull base surgery, phrenic nerve monitoring, cervical pedicle screw monitoring, Direct Nerve Action Potentials (DNAP) in peripheral nerve surgery, Lateral Spread Response (LSR) monitoring in microvascular decompression, MEP monitoring in neonatal spinal cord malformation surgery, cuneate nucleus mapping using the SSEP collision technique, and cortico-cortical evoked potentials (CCEPs) for functional connectivity mapping.
Dedicated IONM for tumours near the motor cortex and language areas, brainstem and skull base tumours, vestibular schwannoma and cerebellopontine angle lesions, microvascular decompression, complex spinal cord and deformity correction, spinal malformation surgery in new-borns and children, peripheral nerve surgery, and select vascular and cardiothoracic procedures with significant neural risk.
24x7 Intraoperative Neurophysiological Protection
The SIMS IONM team provides uninterrupted, round-the-clock intraoperative neurophysiological support for elective, emergency, and complex surgical procedures across multiple specialities. From planned neurosurgical interventions to emergency spinal decompression, our team ensures continuous neural surveillance and rapid intraoperative response capability.
At SIMS Hospitals, IONM acts as an active intraoperative decision-support system by integrating:
This enables early detection of neural compromise, precise intraoperative correction, and improved neurological outcomes.
A complete multimodal IONM capability covering MEP, SSEP, D-wave, Continuous and Triggered EEG, EMG, ECoG, BAER, reflex monitoring, cranial nerve mapping, CoMEPs, DNAP, LSR, CCEPs, and cuneate nucleus mapping.
A fully equipped outpatient neurodiagnostic laboratory providing SFEMG for neuromuscular junction disorders, AFT for dysautonomia, NCS and EMG for peripheral nerve and muscle disease, and Evoked Potentials including VEP, SSEP, and BAEP for visual, sensory, and auditory pathway evaluation.
Together, these capabilities enable our team to ensure continuous neural surveillance and real-time decision-making support, even for the most complex neurological cases.
IONM combines physician-led expertise, advanced monitoring technologies, specialist expertise, real-time clinical judgement, and the ability to transform neurophysiological signals into meaningful surgical decisions when every second matters. From complex brain and spine procedures to highly specialised functional mapping and paediatric monitoring, we provide the neurophysiological intelligence that supports safer surgery along with the best possible outcomes.
At SIMS Hospitals, we believe the success of complex surgery is measured not only by what is treated, removed, or repaired, but by what is preserved. Through real-time neural protection, physician-led expertise, and advanced neurophysiological science, we are committed to helping surgical teams achieve the safest possible outcomes while safeguarding the neurological functions that define quality of life.
At SIMS Hospitals, we don’t observe neural function—we actively intervene to protect it in real time.
