Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Area of Science:

Veterinary Surgery
Ergonomics
Biomechanical Engineering

Background:

Musculoskeletal symptoms (MSS) are common in veterinary surgeons.
Forward head postures during surgery pose unique ergonomic risks.
Exoskeletons are being explored to mitigate surgical risks.

Purpose of the Study:

To evaluate a passive neck-support exoskeleton for veterinary surgeons.
To assess the exoskeleton's effectiveness during live surgical procedures.
To investigate its impact on neck pain and stiffness.

Main Methods:

Within-subject crossover design with eight surgeons.
Surgeries performed with and without the neck-support exoskeleton.
Pre- and post-surgical surveys assessed MSS and perceived effort.
Wilcoxon Signed Rank Test compared outcomes.

Main Results:

No increase in neck pain or stiffness reported when using the exoskeleton.
Greater increases in neck stiffness observed in control surgeries (without exoskeleton).
Exoskeleton use correlated with reduced post-surgical neck discomfort.

Conclusions:

A passive forward head posture support exoskeleton shows promise for reducing MSS in surgeons.
The exoskeleton is a viable intervention for mitigating neck strain during surgery.
Further research can explore broader applications in surgical ergonomics.
