Abstract:
This research aimed to study the effect of anti-fatigue mats in reducing back, leg, and ankle disorders among prolonged standing workers. The design was the quasi-experimental design study. The subjects were divided into two groups consisting of 40 each. The experimental group used the anti-fatigue mats during work for 4 weeks. While the control group worked in normal condition. The back, leg, and ankle flexibility were measured by sit and reach test, and pains were measured by the Standardized Nordic Questionnaires with the Visual analog scale. The result found that pain levels between the two groups were different every week. The experimental group had an average decrease pain level at back, legs and ankle significantly (p-value < 0.05). The control group not had an increased pain level at back, legs and ankle but not significant. The average flexibility of back and legs was not different each week. Only ankle flexibility level was different between the experimental group and the control group in the 2nd week. This research suggested that anti-fatigue mats were beneficial in prolonged standing workers, and effective in reducing pain at back, legs and ankle of the workers.
