Effects of the wearing of tight jeans on lumbar and hip movement during trunk flexion

Abstract

[Purpose] The purpose of this study was to show the effects of the wearing of tight jeans on lumbar and hip movements during trunk flexion. [Subjects] Twelve male subjects were recruited. [Methods] The lumbar flexion angle and hip flexion angle were measured using a dual inclinometer during trunk flexion, with and without tight jeans. [Results] The lumbar flexion angle significantly increased when wearing tight jeans compared to not wearing and wearing of general jeans. The hip flexion angle significantly decreased when wearing tight jeans compared to not wearing and wearing of general jeans. [Conclusion] We suggest that tight jeans might limit normal lumbar and hip movements. So, abnormal lumbar and hip movements induced by tight jeans may be a cause of low back musculoskeletal disorders.
