The pain in the lumbosacral region is a very common and socially important problem. It is established that 90% of the population aged between 35 and 50 years of age are suffering from a certain discomfort in the lumbosacral region. The pain in this region can be of a different nature – neurological, traumatic, psychological, etc. Determining the type and location of pain in the lumbosacral region helps to diagnose correctly, which aids to choose the right treatment. The aim of this research is to define the nature of lumbar pain in patients that visited, for 1 month, the kinesitherapy laboratory at SWU “Neofit Rilski,” Blagoevgrad, and after we analyzed the results, we could determine the kinesitherapy approach. In this research took part 30 patients (16 male and 14 female), which had pain in the lumb?sacral region, at an average age of 45.37 ± 2.61 years. We used the following tests, in order to determine the nature of the pain in the lumbosacral region: Straight leg raise test, Bragard test, and ? test to assess femoroacetabular impingement (FADIR Test). One of the most common tests is the Straight leg raise test. Its proper execution and interpretation can lead to a correct diagnosis of the pain in the lumbar region. We performed the Straight leg raise test, during the examination of every patient. The pain in the lumbar region, provoked by the test, from 30° to 70° is a prove for disc lesion, while above 70° - for problem in the sacroiliac joints. We applied, on some of the subjects, additional stress by performing dorsiflexion (Bragard test). After performing the Straight leg raise test, we determined that 7 of the patients have low back pains connected with the muscles nature, 7 have problems with the sacroiliac joints, and 10 of them are in pain in the lumbar region caused by disc lesion. The test was negative in 6 of the participants. We performed on them additional test for femoroacetabular impingement (FADIR test) which was positive. It could mean starting cause for the beginning of early osteoarthritis of the hip. Recommendations were given to each group for the kinesitherapy approach needed in order for the therapy to be successful. After the recommendations, we followed-up on their condition by performing the tests again and it was determined that there is an improvement in the condition of the patients. In conclusion, we can summarize, the differentiation of the pain in the lumbosacral region, allows us to choose proper kinesitherapeutic means which can lead to control of the pain in that region. That’s why, it is necessary to know, apply and interpret correctly the basic tests used to determine the nature of the discomfort in the lumbosacral region.
