Ergonomic check of an exoskeleton during ENT surgeries
Official title: Ergonomic Evaluation of Exoskeleton Use in Transoral, Endoscopic, and Transcervical ENT Surgery:
Run by East and North Hertfordshire NHS Trust · NCT07855159 · Data updated 2026-11-12
This observational study tests whether wearing an exoskeleton during transoral, endoscopic, or transcervical ENT surgeries reduces neck, shoulder, and wrist strain for surgeons.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are ENT surgeons who regularly perform transoral, endoscopic, or transcervical procedures and are familiar with the exoskeleton (Ottobock) and willing to undergo sEMG monitoring.
✕Probably not a fit
Surgeons without expected benefit may be those who are unable to safely use the exoskeleton or who do not experience notable ergonomic strain.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
In this observational study, ENT surgeons perform procedures with and without an exoskeleton to compare physical strain. Muscle activity is measured with surface EMG and maximum voluntary contraction tests around the neck and shoulders. The study aims to see if the exoskeleton lowers muscle activity, pain, and fatigue during and after surgery. Surgeons must have prior familiarity with the device and participate with sEMG monitoring. The lead site is Lister Hospital in Stevenage, part of East and North Hertfordshire NHS Trust.
Why it matters
Potential benefit: If successful, the exoskeleton could reduce surgeon fatigue and musculoskeletal strain during ENT operations.
How similar studies have gone: Previous work in ergonomic devices for surgeons has shown potential benefits, but results vary by procedure and device.

Show full inclusion / exclusion criteria
Inclusion Criteria: * ENT surgeons who perform a range of transoral, endoscopic and/or transcervical ENT operations. * Willing to participate with surface EMG (sEMG) monitoring and utilise the Ottobock exoskeleton. * • Prior familiarisation with the Ottobock exoskeleton, evidenced by completion of at least five (5) documented surgical procedures using the device before enrolment in the study. Exclusion Criteria: * Pre-existing musculoskeletal problems that limits transoral, endoscopic and/or transcervical ENT operations * Inability to safely or effectively perform surgery using the Ottobock exoskeleton. * Lack of prior familiarisation with the Ottobock exoskeleton, defined as failure to complete at least five (5) documented surgical procedures using the device prior to enrolment in the study.
