Abstract :
Musculoskeletal complaints were frequently found in salesclerks who perform
odd standing posturewhen working. Standing posture correction can reduce the risk
of Musculoskeletal complaints resulted from work. The objective of the research was
to analyze the influence of standing posture correction on Musculoskeletal Disorders
complaints in salesclerks.
This is a Quasi Experiment research with one only pre-test post-test design.
The population was all salesclerks of a Department Store and 30 of them were taken
as the sample by purposive sampling technique. The data were scores of
Musculoskeletal Disorders complaints measured by Nordic Body Map (NBM), before
and after repairing standing position. The paired t-test was used for statistical test
and Wilcoxon was used to analyze the difference in complaints between pre and post
correction.
The results of the research demonstrated that Musculoskeletal Disorders
complaints reduced after the intervention of standing posture correction on Day 1,
namely from 67.43 to 54.43 by wilcoxontest which showed that there was differences
in MusculoskeletalDisorders complaints between pre and post intervention (? =
0.001). In day 2 decreased average from 64.1 to 53.63 with T-Paired test showed (?
= 0.001) there was a difference between Musculoskeletal complaints before and after
intervention. The average of the reduction on Day 3 was from 61.83 to 51.73 by
wilcoxon test which showed (? = 0.001) that there was a difference between
Musculoskeletal complaints before and after the intervention of standing position
improvement. It is concluded that there standing posture correction has some
influence on Musculoskeletal Disorders. It is suggested that salesclerks maintain
natural standing posture with both feet open shoulder width apart during work and
stretching during rest.
