The ergonomics of women in surgery
Among surgeons who regularly perform minimally invasive surgery, as many as 87 % report injuries or symptoms related to job performance. Operating room and instrument design have traditionally favored surgeons...

Quantifying mental workloads of surgeons performing natural orifice transluminal endoscopic surgery (NOTES) procedures
During natural orifice transluminal endoscopic surgery (NOTES), surgeons often have difficulties orienting the surgical view and manipulating instruments accurately, which increases their level of mental and p...

Laparoscopic cholecystectomy poses physical injury risk to surgeons: analysis of hand technique and standing position
This study compares surgical techniques and surgeon’s standing position during laparoscopic cholecystectomy (LC), investigating each with respect to surgeons’ learning, performance, and ergonomics. Little homo...

Higher physical workload risks with NOTES versus laparoscopy: a quantitative ergonomic assessment
Research confirms that surgeons experience physical symptoms due to the unfavorable ergonomics of laparoscopy. The physical effects of performing Natural Orifice Transluminal Endoscopic Surgery (NOTES)—potenti...

A validated subjective rating of display quality: the Maryland Visual Comfort Scale
Minimally invasive surgery requires high-quality imaging to provide effective visual displays to surgeons. Whereas objective measures—pixels, resolution, display size, contrast ratio—are used to compare imagin...

Joint-specific disruption of control during arm movements in Parkinson’s disease
The leading joint hypothesis (LJH) suggests distinct types of control (leading and subordinate) at different joints during multi-joint movements. Taking into account specific features of movements in Parkinson...

Submovements during pointing movements in Parkinson’s disease
Velocity irregularities frequently observed during deceleration of arm movements have usually been interpreted as corrective submovements that improve motion accuracy. This hypothesis is re-examined here in ap...

Ergonomic risk associated with assisting in minimally invasive surgery
Given the physical risks associated with performing laparoscopic surgery, ergonomics to date has focused on the primary minimally invasive surgeon. Similar studies have not extended to other operating room sta...

Open AccessOrigins of submovements in movements of elderly adults
Slowness is a well-recognized feature of movements in aging. One of the possible reasons for slowness suggested by previous research is production of corrective submovements that compensate for shortened prima...

Development of a more robust tool for postural stability analysis of laparoscopic surgeons
Physical difficulties experienced by surgeons performing minimally invasive surgery (MIS) are being given extensive attention by ergonomic researchers. Postural stability, not commonly addressed, is our prime ...

Postural instability does not necessarily correlate to poor performance: case in point
It is very important for surgeons who perform minimally invasive surgery (MIS) to maintain proper postural stability, which kinematic research can determine. Previous studies in surgical ergonomics have shown ...

Efficient control of arm movements in advanced age
The present study addresses the influence of aging on the ability to regulate mechanical effects arising during arm movements due to the multi-joint structure of the arm. Two mechanical factors were considered...
