What Sensory Testing Systems does

Sensory Testing Systems is a Scottsdale, Arizona-headquartered clinical services provider specializing in intraoperative neuromonitoring (IONM), EEG, and pediatric neurodiagnostics. Operating as a strategic subsidiary within the Medsurant Health family of companies, the firm delivers on-site technologists and remote physician oversight to hospitals and surgeons during surgical procedures that place neural structures at risk, and provides tele-EEG and tele-IONM supervision across inpatient and outpatient settings.

The company's service architecture combines in-room neurodiagnostic technologists with off-site supervising physicians, supported by a Phoenix-based EEG lab and an internal Quality Assurance Board that reviews every study. Service lines include routine and long-term EEG, evoked potentials, intraoperative monitoring, and pediatric neurodiagnostics delivered in partnership with leading pediatric hospitals. Talent is sourced and credentialed through the Medsurant Health Academy, a structured 12-18 month fellowship producing 'double boarded' neurodiagnostic technicians.

Revenue mechanics are tied to per-case and per-study service fees billed to hospitals and surgical groups, with go-to-market focused on hospital credentialing, Joint Commission and ABRET accreditation compliance, and surgeon-by-surgeon onboarding. The company maintains Joint Commission Gold Seal of Approval accreditation and ABRET accreditation for both its Academy and its EEG/EP laboratory, and reports coverage across 25 U.S. states plus Puerto Rico, serving more than 150 hospitals and 250 surgeons.

Expansion highlights5 records

Direct peers

• SpecialtyCare: The largest US provider of intraoperative neuromonitoring and other surgical support services, operating a similar managed-services model that places CNIM technologists and remote neurologists into hospital ORs. Direct overlap with STS on IONM staffing, service contracts, and hospital customer base.
• Sentient Medical Systems: Independent US IONM and neurodiagnostic services provider focused on real-time intraoperative monitoring. Closely comparable to STS in customer profile (hospitals and surgeons), service mix, and multi-modality neurodiagnostic offerings.
• Neuro Alert Services: Mid-sized US IONM services company delivering remote physician-supervised neuromonitoring across multiple surgical specialties. Directly comparable to STS on the two-pronged CNIM tech + remote neurologist delivery model and hospital contract structure.

Broad incumbents

• Natus Medical: Established manufacturer and supplier of neurodiagnostic equipment (EEG, EMG, IONM, evoked potentials) and related supplies to hospitals and clinics. Competes with STS for the same hospital budgets but through equipment sales rather than service delivery.
• Compumedics: Global neurodiagnostic equipment manufacturer specializing in EEG, sleep, and IONM systems. Comparable to STS on the EEG and neurodiagnostic modality side but competes through capital equipment sales to the same hospital departments.
• Cadwell Industries: Long-standing US manufacturer of neurodiagnostic systems including EEG, EMG, IONM, and sleep equipment. Comparable end customers (hospital neurodiagnostic labs) but competes as a hardware vendor rather than a clinical service provider like STS.

Others

• Persyst Development: Developer of EEG seizure detection and trending software used in hospital EEG labs and long-term monitoring. Adjacent ecosystem participant — its software typically runs on equipment deployed alongside STS's clinical EEG services rather than competing directly.

Emerging players

• Wave Neuroscience: Specialty provider of qEEG and neurodiagnostic analytics serving clinical and research customers. Partial overlap with STS's EEG service line, focused on advanced analytics rather than broad intraoperative monitoring.
