ABSTRACT
Background: In Poland, about 85% of the population report low back pain (LBP) symptoms overall. Moreover, 70–80% of people
aged below 20 have already experienced back pain. The primary cause of LBP is the loss of spinal lordosis, which initiates changes
in geometry of the spine and has impact on limb arrangement. The aim of the study was to attempt to verify the relationship between
the 2 main curvatures of the spine and its relation to symptoms in different parts of the musculoskeletal system, in a group
of adults. It was assumed that hyperlordosis of the lumbar spine and misbalance of the thoraco-lumbar junction are risk factors
for LBP. Material and Methods: The study coverd 231 first-year students, (aged 19–21) of the University of Economics in Katowice.
There were 103 men aged 19.5±0.8 years and 128 women aged 19.6±0.8 years. The students completed the Nordic Musculoskeletal
Questionnaire (NMQ): 7 days (NMQ7) and 6 months (NMQ6). A Rippstein’s plurimeter, was used to measure the angles of thoracic
kyphosis (KTH) and lumbar lordosis (KLL). Cut of points was set at 30±5. Results: The results indicate strong and very strong correlation
(r = 0.6 and r = 0.8, p < 0.05) between the concave of the back and LBP, which may suggest the relationship between these
symptoms and the increased lordosis. Conclusions: Postural defects in the sagittal plane may predict the occurrence of pain. The
results of the study indicate a higher frequency of pain in people with a higher angle of lumbar lordosis. Med Pr 2018;69(1):29–36
