ABSTRACT
INTRODUCTION One of the most time-and effort-consuming stages in hair transplant surgery is the preparation of grafts. Applying ergonomic principles to mechanical and technical innovations can help in obtaining the goals of reducing the effort exerted and improving efficacy. Having high-quality equipment, an adequate surgical environment, manual skills, and pertinent expertise do not always ensure that work is done in the most efficient manner. It is well known that unnecessary maneuvers, incorrect movements, uncomfortable work positions, changes in sight fixation, and variations in lighting are factors that can lead to fatigue. “Fatigue” is the cumulative effect of work effort on mind and body. It has a negative effect on the subject’s capacities and reduces quality and productivity when compared to results obtained under more optimal work conditions.
