Surgery demands sustained concentration, precise hand control, and consistent visual access to the operating field. It can also place significant physical demands on the surgeon.
During long procedures, surgeons may spend hours standing with the head tilted forward and the neck held in a relatively fixed position. The operating field, surgical table, visualization equipment, and position of other team members can make it difficult to return to a neutral posture.
Over time, this combination of forward-head posture and limited opportunities for movement can create persistent physical demands on the neck, shoulders, and back.
A neck support exoskeleton offers a different approach to surgical ergonomics. Rather than changing the procedure itself, it is designed to help support the posture the surgeon must maintain.
Work-related musculoskeletal symptoms are widely reported among surgeons and procedural physicians.
A systematic review and meta-analysis published in JAMA Surgery examined 21 studies involving 5,828 surgeons and interventional physicians. The researchers found substantial levels of work-related pain affecting the neck, shoulders, back, and upper extremities.
Among studies using the standardized Nordic Musculoskeletal Questionnaire, the estimated 12-month prevalence of neck pain was 65%. The review also found that, among physicians affected by work-related musculoskeletal disorders, 12% had taken a leave of absence, restricted or modified their practice, or retired early.
The authors concluded that the musculoskeletal burden experienced by surgeons and interventional physicians was comparable to that reported in some traditionally high-risk occupations.

A separate systematic review and meta-analysis evaluated 40 studies involving 5,152 surgeons. It reported that:

These figures vary by specialty, procedure type, assessment method, and study population. They should not be interpreted as the expected outcome for every surgeon. However, they demonstrate that neck and upper-body discomfort are not isolated problems within surgical work.
More recent research continues to identify cervical ergonomics as an important concern. A 2024 systematic review found reported rates of cervical musculoskeletal symptoms among surgeons ranging from 10% to 74.4%.
The wide range reflected differences between the studies, but prolonged static neck positioning, open surgery, use of loupes, and neck flexion greater than 30 degrees were among the factors associated with cervical dysfunction.
The researchers also noted that further objective studies are needed to evaluate interventions intended to improve surgical ergonomics.

The evidence does not suggest that every surgeon will develop a cervical condition. It does show that repeated exposure to sustained, non-neutral working postures deserves greater attention as an occupational health issue.
The human head is supported by the cervical spine and the surrounding muscles, tendons, and connective tissues.
When the head is positioned close to neutral, its weight remains relatively well aligned over the body. As the head moves forward, the distance between the head’s center of mass and the cervical spine increases. This creates a larger forward-bending moment.
The muscles at the back of the neck must produce a counteracting force to keep the head from continuing to fall forward. The deeper the forward-head angle and the longer the posture is maintained, the greater the muscular effort that may be required.
This is particularly relevant during surgery because the exposure is not always brief. A surgeon may need to maintain the working posture while:
The physical demand can therefore come from static work rather than large or forceful movements.
The US National Institute for Occupational Safety and Health identifies repetitive work combined with awkward neck posture and prolonged static posture as occupational risk factors associated with neck-related musculoskeletal disorders.
NIOSH also explains that holding the same position for an extended period can increase muscle fatigue and interfere with local blood flow, even when the posture does not initially feel physically demanding.

Surgical posture is influenced by the entire working environment. Adjusting the operating table, visualization equipment, or monitor may improve posture, but these adjustments cannot always eliminate the need to lean forward.
A surgeon may return to a forward-head position because it provides the visual access and precision required for the procedure. The practical question is therefore not always whether forward flexion can be completely avoided, but how the physical effort of maintaining that posture can be better managed.
A neck support exoskeleton is a wearable ergonomic device designed for tasks involving prolonged downward viewing or sustained forward-head posture.
Unlike a powered robotic exoskeleton, a passive neck support exoskeleton does not use motors, batteries, or electronic movement control.
Instead, it uses a mechanical structure to provide adjustable head support and redirect part of the sustained load toward other areas of the body.
The objective is not to lock the surgeon into a fixed position. It is to provide assistance when the head moves into a supported forward-working posture while preserving the movement required to look around the operating field and use surgical instruments.
A neck support exoskeleton is an ergonomic support device, not a medical device. It is not intended to diagnose, treat, cure, or prevent cervical disease.
The ZOIEXO Spine Support Exoskeleton creates a connected support path between the head, back, waist, and optional leg components.
When the wearer tilts the head forward, the adjustable head assembly provides mechanical support. Part of the load is transferred through the exoskeleton structure toward the back and waist rather than being managed entirely by the neck muscles.
When the detachable leg components are used, the support path can extend farther down the body during forward-leaning work.
The head assembly uses a three-axis adjustment system to accommodate different head positions and individual fitting requirements.
The support angle can be continuously adjusted between 0 and 70 degrees, allowing the support position to be matched to different working postures.
The back structure and waist assembly help distribute the transferred load across a larger area of the body.
The back length can be adjusted without tools for users of different heights. The recommended user-height range is approximately 155 to 195 cm.
Detachable and extendable leg straps can provide additional support during standing, forward-leaning work.
The leg components can be removed when they are not required, allowing the system to be configured for different tasks and for seated or standing use.
The product does not use batteries or motors. Support is produced mechanically as the wearer moves into the adjusted working posture.
The standard configuration weighs approximately 1.1 kg, excluding the detachable leg components.

The role of the exoskeleton is to support the surgeon’s working posture without occupying the hands or changing the surgical task.
During forward-head work, the device is designed to carry part of the sustained head load.
By redistributing part of that load through the exoskeleton structure, it may reduce some of the continuous muscular effort required to maintain the posture.
Individual results will depend on the fit, adjustment, working angle, duration of use, and characteristics of the procedure.
Surgeons must be able to look down, turn the head, and occasionally change their line of sight.
The head assembly is therefore designed to provide support without rigidly locking the neck. The actual movement range and level of support depend on the selected angle and the way the product is fitted.
The device provides support through a wearable structure and does not require the user to hold or operate it during the procedure.
This allows the surgeon’s hands to remain available for instruments and other precision tasks.
The product can be configured for standing or seated work. Detachable components allow the support arrangement to be adapted to the procedure and working position.
This flexibility is important because surgical posture can differ significantly between open, minimally invasive, microscopic, and interventional procedures.
A product used in or near an operating environment must be assessed on more than mechanical support alone.
It must also work with the surgeon’s existing equipment, movement requirements, clothing, and facility protocols.
The head-support structure is designed to preserve space around the eyes and face. It may be used with selected surgical headlights, loupes, and protective eyewear, subject to individual fitting.
Compatibility should be evaluated using the exact equipment configuration that will be worn during the procedure.
The product can be worn with selected surgical garments and lead aprons. The correct order of garments and equipment depends on the procedure, apron design, wearer, and facility requirements.
A complete fitting assessment should therefore include all clothing and protective equipment that the surgeon normally wears.
The head support, forward-tilt angle, and back length can be adjusted for different users and working postures.
A correct fit is important. Excessively loose, tight, or poorly positioned components may reduce support, restrict movement, or create unwanted contact pressure.
The head-contact area uses a replaceable foam pad. Individually packaged replacement pads are available for medical or controlled-environment applications.
Breathable back and lumbar contact surfaces are designed to improve ventilation during extended wear.
Cleaning, disinfection, and replacement frequency must follow the product instructions and the facility’s infection-control policies.
A neck support exoskeleton should be evaluated in the context of the actual user, task, and operating environment.
A practical assessment may include:
The first fitting should be completed before the product is used during a long procedure. A short simulated task or controlled trial can help determine whether the selected support angle, back length, and strap positions are appropriate.
Once the wearer is familiar with the fitting process, the average donning time is approximately 20 seconds. First-time users may require additional time and assistance.
The product should not interfere with surgical access, visual equipment, protective clothing, communication, or emergency movement. These requirements should be verified by the user and the relevant facility before routine use.
Surgeons routinely work in positions determined by the needs of the patient and the demands of the procedure.
Long procedures, restricted visual access, and sustained forward-head posture can create a significant but often underestimated physical workload. Published research shows that neck, shoulder, and back symptoms are common concerns among surgical professionals, although prevalence varies between specialties and study methods.
A passive neck support exoskeleton offers a way to address part of this workload. By providing adjustable head support and redistributing part of the sustained load through the back, waist, and optional leg components, it is designed to reduce some of the effort required to maintain a forward-leaning posture.
The objective is simple: provide physical support without getting in the way of the work.
