Literature Reviews Findings -

​

1)Comfort And Ergonomics Evaluation Of a Checkout Workstation:

• The cameras with the CaMAN software used helped the decrease in the musculoskeletal diseases' growth.

• DARTFISH simulation wholly integrated into the CaMAN (mathematical software) was used to investigate also, rate the global comfort index and understand the best comfort position.  

• This advantage can also be seen as a method to increase productivity and improve the psychophysical aspect, as the operator needs to pay less attention and concentration (less stress).

​

2) Ergonomics posture and movement analyses of supermarket checkout operators in the city of Cataguases, MG.

 

• 90% of cashiers were taking sick. The reason is due to MSD (Musculoskeletal disorders )

• Pain during working hours - 73.33% only 40.00% said that they go to the doctor and make 13.33% use of drugs,

• Hence suggested taking a break in between and having a good stretching session.   

• The research found that most cashiers had pain in their trunks, neck, and lower coast.

• The chairs should be adjustable to the worker's height and the nature of the task. There must be a backrest for lumbar support, padding of the appropriate density, and enough space to allow work standing and sitting alternations.
