Brief summary

OBJECTIVE: Compare the effect of the use of two types of arch supports (customized and prefabricated) on the behavior of plantar weight load and osteomuscular symptoms in assembly line workers. METHODS: A randomized trial was carried out with 27 female workers who worked in an orthostatic position, with a mean age of 30.3 ± 7.09 years and weight of 64.85 ± 13.65 Kg, and had osteomuscular symptoms. The Nordic Musculoskeletal Questionnaire was administered and plantar pressure was determined using a computerized baropodometric system (FootWork). The sample was then divided into control group, which wore pre-fabricated arch supports, and intervention group, with wore ethylvinylacetate arch supports during eight weeks. Baropodometric data were collected and the questionnaire was administered again.RESULTS: There was no statistically significant difference in the comparison between groups and baropodometric data. However, a change was noted in the behavior of the load variables between evaluations, with an increase in mean load pressure and maximal plantar pressure (p<0.05). No statistically significant difference was found between groups for any anatomical site in the different evaluations. Within each group, there was a reduction in foot pain and back pain between evaluations (p<0.05). CONCLUSION: Both types of arch support reduced pain symptoms in the lumbar region and feet. After eight weeks of use, there was an increase in maximal and mean plantar pressure and a reduction in plantar surface area with both types of arch support.

Inclusion criteria

women remain standing throughout their daily work shift, wearing the same shoes and cutting leather for the confection of dog chew bones, with signs and symptoms of work-related musculoskeletal conditions in the lumbar region or lower limbs developed while performing the current bone-confection job were included in the study.
