The aim of the study was to determine the parameters of the postural changes between two sitting positions: sitting on a saddle chair compared to sitting on an office chair.
The aim of the study was to determine the impact of an adjustable saddle chair compared to an adjustable office chair with a backrest on sitting posture.
The study involved 60 healthy subjects, mean age 24.7±2.3 years. The study used a MORA 4G system, operating on the basis of spatial photogrammetry.
It was found that there were statistically significant differences regarding the depth of thoracic kyphosis and the angle of the trunk forward inclination. These values were lower when measured on a saddle chair, and the inclination of the upper thoracic section and the lumbar lordosis depth were significantly higher when sitting on a saddle chair.
Sitting on the saddle chair caused the positive effect of an increase of lumbar lordosis. A significant increase in the protraction in the cervical spine was observed, which would be considered to be a negative effect.
本研究的目的是确定两种坐姿之间的姿势变化参数：坐在马鞍椅上与坐在办公椅上相比较。
本研究的目的是确定与带有靠背的可调节办公椅相比，可调节马鞍椅对坐姿的影响。
该研究纳入了60名健康受试者，平均年龄24.7±2.3岁。该研究使用了基于空间摄影测量法运行的MORA 4G系统。
发现胸椎后凸深度和躯干前倾角度存在统计学上的显著差异。在马鞍椅上测量时，这些值较低，而坐在马鞍椅上时，上胸段的倾斜度和腰椎前凸深度显著更高。
坐在马鞍椅上对增加腰椎前凸有积极作用。观察到颈椎前凸有显著增加，这将被视为一种消极作用。
