In the retail supermarket industry where cashiers perform repetitive, light manual material-handling tasks when scanning and handling products, reports of musculoskeletal disorders and discomfort are high. Ergonomics tradeoffs exist between sitting and standing postures, which are further confounded by the checkstand design and point-of-sale technology, such as the scanner. A laboratory experiment study was conducted to understand the effects of working position (sitting versus standing) and…

Electromyographic Analysis of Cashiers in Seated and Standing Postures in a Store Environment
TLDR
A field study was conducted at a European retailer in order to investigate the effects of sitting and standing on muscle activity of cashiers throughout the workday, showing similar trends to previously reported laboratory results.
Characterization of cashier shoulder and low back muscle demands
Biomechanical evaluation of supermarket cashiers before and after a redesign of the checkout counter
TLDR
EMG and optoelectronic motion analysis systems are useful for the quantitative assessment of the effects of the redesign of the workplace biomechanical risk, and suggest that a disk wheel positioned in the bagging area reduces the biomechanicals risk for cashiers and increases time spent resting.
Comparing standing posture and use of a sit-stand stool: Analysis of vascular, muscular and discomfort outcomes during simulated industrial work
The effect of handling products of different weights on trunk kinematics of supermarket cashiers
Workstation configuration and container type influence upper limb posture in grocery bagging.
Comparing dynamic and stationary standing postures in an assembly task
The effect of different supermarket checkout workstations on trunk kinematics of checkout operators.
TLDR
The modified checkout workstation successfully reduced risk of injury in some aspects, particularly the problems associated with lateral bending of the trunk, which may be at high risk of occupational injury due to different workstation demands.
Occupational risk and prolonged standing work in apparel sales assistants
Effects of sitting and standing on upper extremity physical exposures in materials handling tasks
TLDR
Future MMH task designers should consider placing workers in standing postures when feasible to reduce upper extremity loading, but workers should not remain in either configuration for extended periods of time as the negative effects of both workspace geometries can instigate future musculoskeletal disorders.

An analysis of scanning postures among grocery cashiers and its relationship to checkstand design.
TLDR
Although improving the checkstand design may reduce the occurrence of certain awkward postures and static muscle loading conditions among cashiers, the success of these interventions is likely to be limited unless follow-up programmes are instituted to ensure that cashiers are able to use these designs effectively.
Factors Affecting Productivity and Ergonomics of Supermarket Checkers
TLDR
A field study was conducted to examine scanning productivity and ergonomic issues as a function of scanner technology and product type and found that bi-optic scanning was faster and some package types were handled more efficiently.
Design of check-out systems including laser scanners for sitting work posture.
TLDR
The results indicate that a beneficial effect on the musculoskeletal system is achieved by combining the operation of a laser scanner with job rotation and a three-dimensional movement analysis system was employed.
Quantification of Wrist Motions during Scanning
TLDR
It was concluded that the "front-style" check stand minimizes potentially injurious wrist motions because it permits the checker to split the scanning task between the two hands, and the implications for the ergonomic design of the workplace are discussed.
Work-related symptoms and checkstand configuration: an experimental study.
TLDR
The study suggests that optimization of design may be experimentally evaluated, that modification of postural as well as frequency loading may be beneficial, and that adjustability for the individual may be advisable.
Neck and shoulder muscle activity during work with different cash register systems.
TLDR
Work with scanners and pen reader caused, in ranking order, higher loads than conventional keyboard operation in the trapezius, infraspinatus and thoracic erector spinae, but the main problem seems to be the repetitive handling of merchandise and the constant static load regardless of cash register system used.
Ergonomic Evaluation of Checkstand Designs in the Retail Food Industry: A Report Based on Expert Assessment
TLDR
Initial activities to identify ergonomic stressors associated with five common checkstand tyers are described, which are hypothesized to be associated with increased musculoskeletal complaints.
Shoulder posture and localized muscle fatigue and discomfort.
TLDR
Experimental findings showed that posturing hands above shoulder level significantly increased the risk of LMF and postural discomfort even in light-weight manual assembly environs where postural exertions are small, and that cross-modal matching estimates andPostural tremor were more sensitive metrics ofLMF in the shoulder complex than EMG RMS voltage and mean spectral power frequency metrics.

The Effects of Human Interface Design on Wrist Biomechanics during Scanning
TLDR
The need for better scanner designs that will indicate to the user the three-dimensional scan zone created by the two windows is identified, and the design should influence one to use both windows while scanning so that wrist motions will be reduced.
