Checkout cashiers exhibit varied work techniques, particularly in wrist movements during grocery scanning. This study highlights potential for ergonomic improvements by analyzing these differences to prevent cashier symptoms.
Area of Science:
- Occupational health
- Ergonomics
- Biomechanics
Background:
- Checkout cashier roles involve repetitive, hand-intensive tasks.
- Individual workstyles, including technique, may influence symptom development in cashiers.
Purpose of the Study:
- To analyze differences in cashier work technique, specifically wrist movement size during grocery scanning.
- To identify potential ergonomic interventions for cashiers.
Main Methods:
- Video recording of wrist movements for 17 checkout cashiers.
- Qualitative and quantitative analysis of scanning techniques.
Main Results:
- Significant variation observed in the extent of large versus small wrist movements among cashiers.
- Identified distinct patterns in how cashiers handle groceries during scanning.
Conclusions:
- Cashier work technique, particularly wrist movement, varies considerably.
- There is a clear potential for improving cashier work techniques to mitigate risks.

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
