The correlation between the angle of calcaneal eversion and gastrocnemius extensibility with nonspecific low back pain in obese women

Abstract

Background: Individuals with obesity will experience an increase in the angle of calcaneal eversion which has an impact on increasing the workload of the muscles to maintain joint stability, so that tension occurs in the gastrocnemius muscle which affects its extensibility ability. Increasing the angle of calcaneal eversion will cause changes in lumbopelvic alignment so that it can cause low back pain. The aim of the study was to determine the correlation between the angle of calcaneal eversion and gastrocnemius extensibility with nonspecific low back pain in obese women.Methods: This research was a cross sectional analytic study with simple random sampling technique. The number of samples are 78 women aged 36-55 years old. The variables measured were functional pain reduction score in nonspecific low back pain with modified Oswestry disability questionnaire, the angle of calcaneal eversion and gastrocnemius extensibility with goniometer.Results: Our study showed that there was no significant correlation between the angle of calcaneal eversion and gastrocnemius extensibility. However, there was a significant correlation between gastrocnemius extensibility and low back pain at the level of 0.033. In addition, there was a significant correlation between the angle of calcaneal eversion and low back pain at the level of 0,000.Conclusions: There was a significant correlation between the angle of calcaneal eversion and gastrocnemius extensibility with low back pain. However, the angle of calcaneal eversion is not directly related to gastrocnemius extensibility.
