The intraoperative neuromonitoring market is experiencing strong growth as healthcare systems worldwide increasingly prioritize patient safety during complex surgeries. According to Straits Research, the global intraoperative neuromonitoring market size was valued at USD 4.89 billion in 2024 and is projected to grow from USD 5.19 billion in 2025 to reach USD 8.3 billion by 2033, registering a CAGR of 6.05% during the forecast period (2025–2033).
What is Intraoperative Neuromonitoring (IONM)?
Intraoperative Neuromonitoring (IONM) is a medical technique that helps safeguard patients during surgeries by continuously monitoring the functional integrity of the brain, spinal cord, and peripheral nerves. Using methods like electromyography (EMG), electroencephalography (EEG), and evoked potentials, IONM provides real-time feedback to surgeons, enabling them to take corrective actions and minimize the risk of permanent neurological injury. It has become an essential component in complex procedures such as spinal, brain, and vascular surgeries.
Market Trends: AI and Machine Learning in IONM
A key trend driving the global market is the integration of artificial intelligence (AI) and machine learning (ML) into neuromonitoring systems. These technologies are making neuromonitoring more accurate, reducing human error, and offering predictive insights to prevent nerve damage during surgeries. With the ability to process large volumes of neurophysiological data in real time, AI-powered IONM systems are poised to play a transformative role in the surgical landscape.
Growth Drivers
Rising Neurological Disorders
According to Straits Research, neurological disorders such as epilepsy, Parkinson's disease, and multiple sclerosis affect billions worldwide. The Lancet Neurology reports that nearly 3.4 billion people (43% of the global population) had a neurological disorder in 2021, accounting for 443 million DALYs. This growing burden is fueling demand for neurosurgeries, where IONM plays a vital role in enhancing patient outcomes.
Advancements in Surgical Techniques
As surgical procedures become more complex, the role of IONM in reducing risks and improving recovery rates is becoming indispensable. Growing awareness among healthcare providers about its benefits is also driving higher adoption.
Market Challenges
High Cost of IONM Systems
Despite its benefits, the adoption of IONM is often limited due to cost. Setting up a neuromonitoring system can cost between USD 200,000 and 500,000, according to the NIH. In addition, reimbursement policies remain inconsistent across regions, creating barriers in developing economies.
Market Opportunities
Technological Advancements in Devices
The evolution of multimodal monitoring techniques that combine SSEP, MEP, and EMG is expanding the scope of IONM. Portable and user-friendly devices are enabling broader adoption across surgical centers. With strong R&D investments, innovations in neuromonitoring devices are set to unlock new opportunities for growth.
Regional Insights
North America
North America dominates the global intraoperative neuromonitoring market. According to Straits Research, the U.S. leads due to its advanced healthcare infrastructure, significant surgical volumes, and strong regulatory standards. The CDC reports around 1.4 million nervous system surgeries annually in the U.S., highlighting the demand for IONM services.
Asia-Pacific
The Asia-Pacific region is projected to see the fastest growth, led by China, India, and Japan. The Asian Development Bank projects healthcare spending in the region will reach USD 4 trillion by 2030, fueling the adoption of advanced medical technologies. China’s initiatives under the Healthy China 2030 plan are further driving IONM demand.
