The question of school furniture has often come up when looking for ways to prevent or reduce low back pain (LBP) in school-aged children. Children between the ages of 14 and 17 years old come in a wide range of sizes and shapes. One size desk may not be best for everyone.
Is an adjustable desk needed? Would it be better to have a seat that is inclined forward more? Or perhaps a more slanting surface of the desk would be better? In this study, LBP in this age group was compared to the dimensions of school furniture. Weight and size of the children and weight of backpacks were also measured.
The results of this study showed no link between school furniture and LBP. Children with LBP were more likely to adjust their desks and chairs or ask for adjustable furniture. The use of adjustable school furniture was a result rather than a cause of LBP.
Height and/or weight was not linked with LBP. A more significant factor was the use of backpacks. The weight of the backpack was not an issue. The method of carrying heavy school bags was the real problem. Children were more likely to have LBP if they carried the backpack or school bag in one hand or over one shoulder.
The authors suggest more study is needed to understand the biomechanics of backpacks and LBP. Uneven loading on the spine from one-sided carrying of the packs may be the cause of LBP but his has not been proven.
It does not appear that furniture design is a major factor in LBP among this age group. Until further research can be completed, it is not advised to spend time and money developing school furniture that can prevent LBP in school-aged children.
