Backpacks and Posture Backpacks and Stability Backpacks and Children Because students stand and move with backpacks that may be heavy, posture and balance may be altered. The purpose of this study was to determine if posture or postural stability change with backpack weight, the type of backpack worn or the location of the backpack on the spine. Forty healthy students ages 10 -14 years volunteered to participate. A force plate and a six camera motion analysis system were used to measure posture and postural balance during three types of tests: static, dynamic and fall forward. Static tests were performed without a backpack, and with three backpacks manufactured by different companies, each tested in two different locations (high on the back; low on the back) with three different loads (no weight; 10% of the bodyweight; 20% of the bodyweight). Dynamic and fall forward tests were performed without a backpack and with the three backpacks weighing 20% of the bodyweight which were worn high on the back. Results indicate that postural stability and body position while wearing a backpack weighing 20% of the body weight are significantly different from conditions is which no backpack or a backpack with 0 or 10% of the bodyweight is worn. Standing with a backpack weighing 20% of the bodyweight results in an anterior movement of the shoulder and head, an increase in the movement of the center of pressure and an anterior, superior movement of the center of gravity. The location of the backpack also significantly altered postural stability and posture. When the backpack was worn in the high position, postural stability, as indicated by decreased movement of the center of gravity within the base of support, was greater than the low position but the head was in a more anterior position. The type of backpack had no significant effect on postural stability or posture. In addition to the changes resulting from increase backpack weight and backpack location, the study found evidence that gender, body mass index and age may also alter stability and posture when wearing backpacks. These potentially at risk populations should be studied further to identify risks of injury and falls. 2005-07-14 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1115391000 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1115391000 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
