Record Number: N/A
Study Description
Methodology: Prospective study design (Cross-sectional study)
Method: Cross sectional survey was used at the start of the study to determine factors that might
predict the outcome of a subsequent episode of low back pain and they also used an interview
Intervention:
Setting: Two general practices in south Manchester.
Geographical: N/A
Cultural: N/A
Participants: 490 subjects (203 men, 287 women) aged 18-75 years.
Data Analysis: Evaluated the outcome of each new consulting episode by means of two approaches.
First, reviewed the patients' records for subsequent consultations up to six months after the index
consultation and classified patients into three groups. Second, they evaluated outcome from follow up
visits among the subgroup of survey responders.
Authors Conclusion: The results are consistent with the interpretation that 90% of patients with low
back pain in primary care will have stopped consulting with symptoms within three months. However
most will still be experiencing low back pain and related disability one year after consultation.

Record Number: Volume 12, Issue 1 , Pages 63-70
Study Description
Methodology: Cross-sectional study
Method: The National Electronic Injury Surveillance System was queried for all cases of low back pain
presenting to emergency departments between 2004 and 2008. Incidence rate ratios were then
calculated with respect to age, sex, and race. The chi-square statistic was used to identify statistically
significant differences in the incidence of low back pain requiring emergent medical evaluation between
subgroups.
Intervention:
Setting: United States of America
Geographical:
Cultural:
Participants: United States population estimates.
Data Analysis: Incidence rate ratios were calculated to determine the influence of age, sex, and race on
the development of low back pain requiring emergent medical evaluation.
Authors Conclusion: Age, sex, and race are significant risk factors for the development of low back pain
necessitating treatment in an emergency department.

Study Description
Methodology: Repeated-measures design (cohort study)
Method: A cohort of high school students in Montreal, Canada, was followed prospectively over a 12-
month period. Students in grades 79 were assessed from three schools two public inner-city schools
and one smaller private school. In accordance with the laws of the province of Qubec, all students and
the parents of those aged less than 14 years provided a signed, informed consent before entry into the
study. Data were collected three times over the year: at inception (t1, fall of 1995), 6 months (t2, spring
of 1996), and 12 months (t3, fall of 1996). Each time, students were asked to complete a questionnaire
that addressed lifestyle and musculoskeletal health. They also underwent a series of measurements of
their height, weight, abdominal muscle strength, and trunk and lower limb flexibility
Intervention:
Setting: Montreal, Canada
Geographical:
Cultural:
Participants: Students in grades 79
Data Analysis: Univariate comparisons were carried out on the two 6- month time periods separately. In
this way, seasonal influences of activity and work were separated.
Authors Conclusion: The results of this study indicate that low back pain is common in adolescents,
with a cumulative annual incidence of 17 percent. Factors associated with development of low back pain
in adolescents were a high growth spurt, poor quadriceps and hamstrings flexibility, working during the
school year, and smoking. Although prevention strategies have been addressed in the occupational
setting (59, 60), our results suggest that more research is needed regarding prevention before people
enter the workforce. Improved knowledge and awareness of the vulnerability of the back, the need for
good flexibility, and refraining from smoking are all areas that require further investigation.
