Posture Training for Middle Schoolers

Overview

The goal of this clinical trial is to investigate if posture training can improve back pain and posture in middle school students. The main questions it aims to answer are: * Can posture training reduce back pain in middle school students? * Can posture training improve body posture in middle school students? Researchers will compare training and control groups to see if posture training reduces pain and improves body posture. Participants will; * Fill a survey assessing pain and body posture at three time points: before the training, immediately after, and at the 1st and 3rd months * Attend three sessions of training on correct body posture and spinal health and its importance, and exercises to be done for spinal health

This experimental study has been designed with a pre-test-post-test control group and repeated-measures. The data will be collected between October 15, 2025 and March 15, 2026. The study will be conducted in two Middle School in a region with a total students of 1170 in the 2024-2025 academic year. It is assumed that the population size will be similar, and a power analysis (0.80 power and 0.05 margin of error) has been conducted to estimate the sample size. As a result the target is to reach a total of 80 students, with 40 students in both the experimental and control groups, including a 20% attrition rate. The study will begin after the institutional permission, ethics committee approval, and written consent from the parents and verbal consent from the students. After the pre-test is completed, the students in the experimental group will be given training planned in a total of three sessions on correct body posture and spinal health and its importance, and exercises to be done for spinal health. The research data will be collected before and after the intervention, in the 1st and 3rd months. In the study, the data will be collected with the personal information form prepared by the researchers in line with the literature information and the Back Pain and Body Posture Assessment Tool, the validity and reliability of which has been studied in Turkish. In this study, the Statistical Package for Social Science for Windows (SPSS) package program will be used to analyse, examine and perform the analysis of the data. In the data analysis, ordinal variables will be evaluated as arithmetic mean and standard deviation, minimum, maximum. As statistical analysis methods, Student's t test and one-way variance (One Way ANOVA), and Mann-Whitney U test will be used, and the significance level will be considered at p\<0.05 level.
