PROCEDURES
This evaluation will be conducted in a private room or behind a curtain to give
you privacy. We will ask you your birth month and year as well as your level of
physical activity. Then we will ask you if/how often you are exposed to
cigarette smoke and whether it is first-hand or second-hand. We will measure
your height and weight and the size of your neck and head. Then we will make a skinfold measurement under your chin. We will place a device, which is like a
head band, on your head. You will move you head and neck in 6
directions—forward, backward, right side, left side, right rotation, and left
rotation—and the device will measure the angles you move. Next, you will be
asked to push your head against a padded button in three directions: forward,
backwards, and sideways. This will be repeated three times and the test will
take approximately 9 minutes. Then we will ask you to push your head against the
button, this time hold it for 30 seconds. This will also be performed in each
direction: forward, backwards, and sideways. You will get a 1-2 minute rest
period between tests, so it will take approximately 6 minutes. The entire
procedure should not last longer than 30 minutes. We will capture images (video
and still photographs) of you during this experiment to measure your posture and
how you move your neck. We might want to show your images in a public setting,
such as in classrooms or at a meeting. The images will only be used in this way
if you have signed a separate form giving permission to do so.
RISKS, STRESS, OR DISCOMFORT
The risks for this study are minimal. This experiment is not intended to strain
muscles. We will not ask you to strain your muscles. However, some people may
feel slight discomfort or tiredness after the procedures. You can stop at any
time. You might feel slight pressure on your skin for a few seconds when the
calipers are applied to measure the skinfold under your chin. Some people feel
self-conscious when they are video recorded. Some people feel that providing
information for research is an invasion of privacy.
BENEFITS OF THE STUDY
We hope the results of this study will help to understand the characteristics of
the neck for the advancement of child and small female safety. You may not
benefit from taking part in this study.
OTHER INFORMATION
This study is voluntary. You can stop or withdraw your data and/or recordings at
any time. Information about you is confidential. We will remove your name from
all the study information and use a code instead. The link between your name and
the study information will be kept in a secured location, separate from the
study information. Only the primary investigator will have the master list of
the names and codes. The investigator will destroy the master list upon
completion of the study. If you have given us separate permission to
keep your digital images longer, your images will remain coded as in the master
list to enable your access. You will be compensated $20 for your time and
participation. Government or university staffs sometimes review studies such as
this one to make sure they are being done safely and legally. If a review of
this study takes place, your records may be examined. The reviewers will protect
your privacy. The study records will not be used to put you at legal risk of
harm.
WHO IS SPONSORING THIS STUDY?
The funding for this study is being provided by the National Highway Traffic
Safety Administration (NHTSA). The
