Nowadays, a large number of students experience spinal pain quite early in life due to heavy school bag loads. Moreover, external forces in the form of school bags may influence the normal growth, development of children and adolescents, and also maintenance of alignment of their bodies, which can pose a huge threat to postural integrity under external load. Awareness about the appropriate load and placement of backpack is thought to be important in reducing musculoskeletal complications among children's.
A systematic review of randomized controlled trials (RCTs) was conducted to determine the influence of postural deviations due to backpack load among school children's. Electronic databases were searched, and a reference list of retrieved articles were relevant to postural changes among school children with the backpack were screened. Reviewers graded the papers according to Lloyd-Smith's hierarchy of evidence scale. Papers were quality appraised using a modified Crombie tool.
Twelve papers were identified for inclusion in this review. Methodological difference limited our ability to collate evidence.
Most of the articles recommended that backpack load limit for school children should be 10-15% of body weight. However, the appropriate load limit for school children is limited due to lack of articles, the low hierarchy of evidence, and small sample size. This review constrains the use of published literature to inform good load limit of school pack among the school children.
如今，大量学生因书包负重过早地出现脊柱疼痛。此外，书包形式的外力可能会影响儿童和青少年的正常生长发育以及身体姿势的维持，在外部负荷下对姿势完整性构成巨大威胁。人们认为，了解背包的适当负重和放置方式对于减少儿童肌肉骨骼并发症很重要。
进行了一项随机对照试验（RCT）的系统评价，以确定书包负重对学童姿势偏差的影响。检索了电子数据库，并筛选了与背书包学童姿势变化相关的检索文章参考文献列表。评审人员根据劳埃德 - 史密斯证据等级量表对论文进行分级。使用改良的克龙比工具对论文进行质量评估。
确定了12篇文章纳入本综述。方法学差异限制了我们整理证据的能力。
大多数文章建议学童的书包负重限制应为体重的10% - 15%。然而，由于文章数量不足、证据等级低和样本量小，学童的适当负重限制受到限制。本综述限制了利用已发表文献来确定学童书包的良好负重限制。
