The Importance and Influence of the Strength of the Lumbo-Abdominal Corset Muscles on the Prevention and Occurrence of Lumbar Pain Syndrome

Abstract Lumbar spine pain is becoming more widespread as a health problem and is one of the main reasons for short-term incapacity for work. The goal of the research was to determine, by applying appropriate tests, whether complaints in the lumbar part of the spine are associated with reduced muscle strength that participates in spine stabilization. This research included a total of 100 students of the State University in Novi Pazar, Serbia. Lumbar functional tests The Biering-Sorensen test, 60-degree flexion test, and side plank test were used to assess trunk muscle strength. After the examination, the students filled out a questionnaire for the analysis of the musculoskeletal system. The results showed that there was a significant difference between the compared groups regarding the strength and power of the lumbo-abdominal corset muscles. The Biering-Sorensen extensor endurance test stands out as an important test, which is significantly associated with the presence of back problems. An increase in the value of this test by one measurement unit was associated with a decrease in the probability of lower back pain (Exp(B)=0.941; 95% CI: 0.911 to 0.972; p=0.000). All the above research results indicate that strengthening key muscle groups, such as trunk muscles, paravertebral muscles, and hip muscles, plays a significant role in preventing back pain and maintaining general physical health.
