Poor posture has been shown to decrease both visceral and respiratory/circulatory function as well as to increase neuro-musculoskeletal system stress. Improper postures of children at school and in daily life can affect their physical and psychological development. In particular, many children who refuse to go to school or who have experienced school refusal have physical and mental problems. Given that posture is closely related to one’s psychological state, modifying one’s posture can improve both physical and psychological health problems. This study examined the changes to school-refusing students’ physical and psychological condition after attending an intervention to improve their posture. The participants were 65 high school students who have experienced school refusal and were attending a program to modify their posture for 2 months. Their posture and psychological states were recorded both pre- and post-intervention with the following measurements: postural alignment and spinal curve according to a sagittal plane, the General Health Questionnaire 30 (GHQ), and the Subjective Adjustment Scale (SAS). Post-intervention, most of the participants saw improvement in their postural alignment (e.g., trunk inclination in standing position, P < 0.001, 95%CI [2.00, 4.00]). Participants with improved standing posture post-intervention had higher SAS scores (e.g., feeling of acceptance and trust, P < 0.05, 95%CI [−3.00, −0.00]). We found that easy-to-implement postural interventions have a positive effect on students’ mental health. Furthermore, it was suggested that their adjustment to school would also improve as their posture improved. The contribution of this study shows that it is possible to care for the physical and mental health of students without using special facilities and techniques. It is hoped that the findings of this study will lead to an improved adjustment to both school or novel environments, as well as prevent health-based school refusal.

不良姿势已显示会同时降低内脏和呼吸/循环功能，并会增加神经肌肉骨骼系统的压力。儿童在学校和日常生活中的不正确姿势会影响他们的身心发展。尤其是，许多拒绝上学或遭到拒绝上学的孩子都存在身体和精神方面的问题。考虑到姿势与一个人的心理状态密切相关，改变一个姿势可以改善身体和心理健康问题。这项研究调查了在接受干预以改善其姿势后拒绝入学学生的身体和心理状况的变化。参加者有65名高中生，他们曾经历过拒绝上学的经历，并参加了为期2个月的改变姿势的计划。在干预之前和之后，通过以下测量记录他们的姿势和心理状态：根据矢状面的姿势对准和脊柱弯曲，《一般健康状况调查表》 30（GHQ）和主观调整量表（SAS）。干预后，大多数参与者的姿势都得到了改善（例如，站立姿势的躯干倾斜，P  <0.001，95％CI [2.00，4.00]）。干预后站立姿势得到改善的参与者的SAS评分更高（例如，接受和信任的感觉，P  <0.05，95％CI [-3.00，-0.00]）。我们发现易于实施的姿势干预措施对学生的心理健康具有积极作用。此外，有人建议，随着他们姿势的改善，他们对学校的适应也将有所改善。这项研究的成果表明，可以在不使用特殊设施和技术的情况下照顾学生的身心健康。希望这项研究的结果能够导致对学校或新环境的调整得到改善，并防止基于健康的学校拒绝入学。
