DESCRIPTION OF THE RESEARCH PLAN.
Please be sure to address all of the following questions using lay language. Please write in
complete sentences.
1. Provide a brief (no more than one to three paragraphs) review of the pertinent literature
and identify the need for the study
The increasing incidence of back pain in adolescents has sparked an interest in
backpack safety within the medical and education communities. While no definitive link has
been established between backpack use and back pain, the relationship between the two is
of interest due to long-term implications of back pain in children. Research indicates a history
of back pain as a child may be a predictor of future back pain as an adult. Spinal pain is one of
the most costly and debilitating problems of adults in industrialized countries.
Consequences of wearing backpacks include: poor postural alignment, muscle
fatigue, impaired shock absorption, and nerve compression in the shoulder. Based on the
results of several studies, the American Physical Therapy Association (APTA) has developed
the following recommendations for backpack use: 1) backpacks should contain no more than
15% of the carrier’s body weight and 2) backpacks should be worn high in the mid-thoracic
area, with straps over both shoulders. While it is generally agreed upon that backpacks
should weigh no more than 15% of the carrier’s bodyweight, it is not known if the manner in
which the backpack is carried affects the carriers’ posture and manner of walking. It is
common practice for middle and high school students to carry their backpacks over one
shoulder or slung very low on their backs as opposed to wearing them high and over both
shoulders as recommended. The purpose of this study is to compare the effects of three
different methods of wearing a backpack, loaded with 15% of body weight, on gait
characteristics (stride length, cadence, velocity, base of support, and single stance time).
The methods of carrying a backpack that will be compared include: 1) wearing the backpack
in the mid-thoracic area with straps over both shoulders as recommended 2) wearing the
4
EXAMPLE: Completed Full Review Application
backpack in the low lumbar area with straps over both shoulders 3) wearing the backpack in
the low lumbar area with a strap over one shoulder and 4) a control condition in which no
backpack is worn during walking. If it is determined that the manner in which a backpack is
worn affects gait kinetics, then educating children, teachers, and parents on proper
backpack wearing techniques may help avoid future back pain and other medical problems.
2. Clearly state the purpose(s) of your project
The purpose of this study is to determine the effects of three different backpack carrying
methods on the gait kinetics (step length, cadence, velocity, single stance time, and base of
support) of healthy seventh and eighth graders.
3. Describe your study design. If applicable also identify your variables and hypotheses.
This study is a repeated measures design in which each child will be asked to walk while
carrying a backpack under 4 different conditions (independent variables): 1) wearing the
backpack in the mid-thoracic area with straps over both shoulders as recommended 2)
wearing the backpack in the low lumbar area with straps over both shoulders 3) wearing the
backpack in the low lumbar area with a strap over one shoulder and 4) a control condition in
which no backpack is worn during walking
This study will use the GAITRite system to measure the dependent variables of:
Stride length (cm)
Step length (cm)
Single limb stance time (sec)
Double limb stance (sec)
Cadence
Velocity
Base of support (cm)
4. Explain your instrumentation and methods. (Please explain your proposed methodology
step by step.)
Instrumentation
This study will use the GAITRite system to measure the dependent variables of:
Stride length (cm)
Step length (cm)
Single limb stance time (sec)
Double limb stance (sec)
Cadence
Velocity
Base of support (cm)
The GAITRite consists of an electronic walkway containing six sensor pads imbedded
within the 24in X 144in active area of the mat. Within the sensor pads, there is a grid
style layout of 48 X 288 sensors (0.5 inches on center). The sensors record the
subjects’ footfalls and the computer calculates the parameters listed above. An IBM
compatible computer will be used in order to process each subject’s footfall patterns
as they walk across the mat under each of the four research conditions described in
the procedures. From the footfall information, the program will calculate each of the
dependent variables.
Validity and Reliability:
5
EXAMPLE: Completed Full Review Application
The validity and reliability of the GAITRite gait analysis system have been found to be
good. The GAITRite gait analysis system has been compared to the paper and pencil
method and the video-based method of analyzing gait, both validated “gold
standards,” using intra-class correlation coefficients (ICC). When GAITRite was
compared to the paper and pencil method, ICCs for spatial parameters were
excellent (right step length = 0.97; left step length = 0.99), while ICCs for temporal
parameters were fair (right step time = 0.67; left step left step time = 0.61). When
GAITRite was compared to video-based method, ICCs for temporal parameters were
excellent (right step time = 0.97; left step time = 0.95), while ICCs for spatial
parameters were weaker (right step length = 0.44; left step length = 0.85).
Examination of reliability between GAITRite and paper and pencil method revealed
no significant differences between spatial parameters. Examination of reliability
between GAITRite and video-based method revealed no significant differences
between temporal parameters. The authors of the validity and reliability study
concluded that GAITRite was a valid and reliable tool for assessing spatial and
temporal aspects of gait. A calibrated scale will be used for weight measurements,
and a calculator will be used for calculating 15 percent body weight.
Procedures:
Both the subjects and their legal guardians will be informed of the purpose,
procedures, and alternatives to participation. Students and parents will then be invited to
sign an informed consent form.
Consent forms for the 7th and 8th grade students, parental consent forms, and
health forms will be sent home with students along with a letter of invitation from the USN
principal. (See Appendices ) Parents will be asked to sign the consent form and complete
the health form and return them to school with their children. Seventh and eighth grade
student participants will also be asked to sign consent forms. Students’ legal guardians will
also be asked to fill out a medical history form to insure that no subjects have a medical
condition or history of trauma that would contraindicate participation (See appendices).
Children will be excluded from participating in the study if they have any of the following:
history of heart condition, lung condition, any current musculoskeletal disorder, or any
injury to the lower extremities, upper extremities or spine within the last three months that
would cause difficulty with walking or prevent carrying a backpack.
Subjects will be asked to wear athletic shoes and comfortable clothing for
participation in the study. Subjects will also be asked to bring their school backpack with
them to the study.
Upon arrival to the study area, each subject will be weighed with and without their
own back pack. The weight of the subject with the backpack is descriptive information to
determine the typical load these students are carrying at a given time. The weight of the
student without the backpack will be used to determine 15% of the subject’s body weight.
This is the recommended maximum backpack weight by APTA. As each subject is weighed,
he or she will be asked a series of questions about how they typically carry their backpack.
These questions are also for descriptive purposes.(See appendices)
Each subject will be asked to walk across the GAITRite mat three times under each of
the conditions listed below.
a. Walk across the GAITRite mat three times with no backpack (Control)
b. Walk across the GAITRite mat three times with the standardized backpack worn over
both shoulders and placed in the mid-thoracic area as recommended by the APTA.
6
EXAMPLE: Completed Full Review Application
c. Walk across the GAITRite mat three times with the standardized backpack in the
strung low position (defined below)
d. Walk across the GAITRite mat three times with the standardized backpack across one
shoulder with the straps remaining in the strung low position (defined below)
Defining Carrying Methods:
---Correct carrying position: top of backpack level with the spine of the scapula
---Strung low carrying position: top of backpack level with the inferior angle of the
scapula
---One shoulder strung low position: backpack carried on one shoulder (subject’s
preference) with straps extended to the same length as in the normal strung low
position.
Conditions will be presented in random order as determined by drawing numbered
cards out of a box. A standardized backpack will be used that contains 15% of the subject’s
body weight for all trials with the exception of the three control trials. A starting and
stopping point eight feet from the mat will also be designated to account for the effects of
acceleration and deceleration. A two-minute rest period will be allowed between each
pass to prevent fatigue.
The GAITRite system (see description above) will be used to measure the dependent
variables of: Stride length (cm), Step length (cm), Single limb stance time (sec), Double
limb stance (sec), Cadence, Velocity, base of support (cm)
At the conclusion of data collection the investigators will instruct each subject in the
proper method of carrying a backpack as recommended by the APTA. Each student will
also receive a handout with this information. (See appendix)
5. Describe your plan for data analysis and statistics
Forty subjects will be used as determined by pilot study findings. A two way repeated
measures ANOVA will be used to analyze this data. A paired t-test with a Bonferoni
correction post hoc will be used. This will allow researchers to determine if there is a
significant difference in the kinetic aspects of gait identified above based on backpack
carrying method
ASSESSMENT OF RISKS AND BENEFITS:
1. List and describe any possible risks.
Be sure to include potential physical, psychological, and social risks.
For each risk listed also describe risk frequency, severity and reversibility.
Risks involved in this study include the possibility of muscle soreness from lifting and
carrying the weighted backpack; however participants in this study are middle school youth,
who routinely carry backpacks containing significantly more weight than will be used in this
study. There is also the slight possibility of tripping and falling while carrying the weighted
backpack, which could result in injury.
2.
Describe procedures and precautions to be taken to avoid or minimize each risk listed
above to the extent possible. In order to reduce both the possibility of muscle
soreness and falls, subjects will be asked to only carry 15% of their body weight. This is
the maximum weight for backpack safety recommended by the APTA. A maximum
backpack weight of 30 pounds will be the limit, regardless of the subject’s body
7
EXAMPLE: Completed Full Review Application
weight, in order to further prevent any injury or soreness. A clear path around the
mat will be enforced to prevent tripping. Subjects will also be asked if they are
feeling any discomfort several times during data acquisition, and if they report
discomfort the backpack will be repositioned. If at any time the subject feels
uncomfortable, he or she can choose to stop.
3. List and describe any benefits. Each student will be instructed in the proper method
of carrying a backpack at the end of the data collection session, and each student
will be given a handout to take home (see appendices for a copy of the handout).
4. If appropriate, describe any withholding of normal treatment and alternative treatments.
N/A
5. Based on the information you provided above, identify the risk:benefit ratio for the
subjects.
Although there is a slight chance of muscle soreness and/or tripping while carrying
the backpack during the study, the participants will be learning how to carrying a
backpack correctly at the conclusion of data collection which may help to reduce the
potential for injury in the future.
6. Explain the conditions under which an individual subjects’ participation in the study
would be discontinued.
The researchers will withdraw subjects if they complain of back pain, neck pain, or
if they become ill.
7. Explain the conditions under which the entire study would be discontinued if hazards
materialize.
The study will be discontinued or the weight placed in backpacks reduced if the
investigator find that students routinely complain of muscle soreness or if tripping is
routinely observed during data collection. If the weight placed in the backpacks is
reduced a change of protocol will be requested from the IRB.
8. Does this study involve deception?
Yes________ No____X_____
If yes, how and when will you provide debriefing?
