The effect of education on proper wearing of a backpack was studied to determine whether or not a middle school population would improve posture during load carriage by maintaining a more natural posture and to determine if schoolchildren would comply with proper backpack wearing.
17 middle school children with a mean age of 12.7 years were randomized into control and intervention groups. Participants were videotaped in four conditions from an anterior view and from a lateral view. Members of both groups participated in Sessions A and C, which consisted of videotaping of the four conditions. Intervention members additionally participated in Session B, consisting of education on how to wear a backpack properly. All participants were interviewed concerning their participation and its effect on how they wore their backpack. Video footage was analyzed to calculate the change in skeletal angles as a result of different methods of load carriage. Interview data was coded and analyzed.
No quantitative significance was found between control and intervention groups in regards to education on proper backpack wearing improving posture. Interviews revealed that intervention group members benefited from the education on proper wearing of a backpack. 87.5% of the intervention group members proceeded to continue wearing the backpack properly after the education intervention.
Education regarding proper wearing of a backpack may impact the middle school aged child by improving quality of life as noted through decrease in reports of musculoskeletal pain by participants.
研究教育对正确佩戴背包的影响,以确定中学生群体在负重行走时能否通过保持更自然的姿势来改善体态,以及小学生是否会遵守正确的背包佩戴方式。
将17名平均年龄为12.7岁的中学生随机分为对照组和干预组。从正面和侧面两个视角对参与者在四种情况下进行录像。两组成员都参与了A和C环节,这两个环节包括对四种情况的录像。干预组成员还额外参与了B环节,该环节包括关于如何正确佩戴背包的教育。就他们的参与情况及其对背包佩戴方式的影响对所有参与者进行了访谈。对视频片段进行分析,以计算不同负重方式导致的骨骼角度变化。对访谈数据进行编码和分析。
在正确佩戴背包以改善体态的教育方面,对照组和干预组之间未发现定量差异。访谈显示,干预组成员从正确佩戴背包的教育中受益。87.5%的干预组成员在教育干预后继续正确佩戴背包。
关于正确佩戴背包的教育可能会对中学生产生影响,如参与者报告的肌肉骨骼疼痛减少,从而提高生活质量。
