Analysis of body imbalance in various writing sitting postures using sitting pressure measurement

[Purpose] This study set out to substantiate the importance of the right sitting posture by measuring the sitting pressure. It also described the influence of an imbalanced sitting posture on the body. [Subjects and Methods] The subjects included 30 healthy adults. A pressure mapping system was used to measure the sitting pressure in the right, one side prone, chin propped, and slumped sitting positions. [Results] The WDI (XAP) showed a statistically significant difference between the 3 incorrect postures (one side prone, chin propped, and slumped sitting) and the right sitting posture. With regard to the WDI (XLR), there was a statistically significant difference between the right sitting posture and the one side prone sitting posture only. [Conclusion] One side prone sitting was found to affect the body balance most adversely. This imbalanced posture may have an indirect effect on chronic diseases. The results prove that it is important to assume a proper posture to maintain body balance.
