To whom it may concern,
I am currently a fourth year physiotherapy student at the University of
South Australia and we are participating in a grand study with the topic
of high school students and their backpacks. I recently surfed on the
internet to come across a letter that Rick Heinrich sent back in 1995
which had a similar interest and question to our own. I am now
contacting all of those who kindly replied to him back in 1995 in the
hope that more data, research, information or even speculation has
evolved since. Our section of the study involves taking 4 digital photos
of kids between the year levels of grade8-grade12 (12-17 year olds. The
photos are of a) how they normally carry their back pack between
classes, b) with the backpack on two shoulders, c) with the backpack on
two shoulders and with any other extra straps done up (i.e. waist and
chest straps), and d) a photo without their backpack on therefore a
normal posture shot. Two photos are taken at once, one from the front
(anterior) and one from the side (lateral). The kids have stickers
placed on anatomical landmarks in order for us to later determine head
and neck posture positions and alterations via certain angles. These
angles calculated are a)cranio-vertebral angle (C7), b)
cranio-horizontal angle c) sagital shoulder angle and d)anterior head
tilt. From these angles we are hoping to observe differences in head and
neck postures with the different type of photos, and therefore, analise
whether or not different techniques of bag carrying have an effect on
this posture. Since there are 90 fourth year students involved in this
study and the data collecting is carried over a period of 6 months
(every morning, 5 days a week) the sample size should reach somewhere
between 2000-3000 school children. The other sections of the study
involve anthrpometrics, questionaire and bag weighing. The bag weigh
involves taking bag measurements and distributing the contents of the
bag into given categories and alternatively weighed.
As you can see, this is an extnsive study on a grand scale and it has
had little research applied to it. If you are able to provide any given
information that would be useful for our literature review or know of
further avenues that I may be able to approach to get the information I
need then I would really appreciate to time you take to contact me.
Feel free to contact me if this study interests you and you would either
like further insight into the study or even the results (assuming they
will be valid) when we eventually get around to analysing them.
Thank you for your time in anticipation,
