Objective: The purpose of the study was to compare the pressure pain threshold (PPT) of soft tissue and the curvatures of the spine in a sitting position and to estimate associated physical risk factors with low back pain (LBP) in young adults. Subjects: White-collar workers (n= 139), both women (n = 51) and men (n = 88) were separated into a control group (n = 82) and a low-intensity LBP (NRS < 3) (n = 57). Methods: The PPTs were tested utilizing the Wagner algometer. The curvatures of the spine were measured employing the photogrammetric method. In the logistic regression model, the odds ratio (OR) was estimated with ±95% confidence interval (CI) indicating the probability of the reported LBP. Results: The PPTs of soft tissue (OR = 1.1; CI = 1.02–1.19; p < 0.05) and the angle of the thoracolumbar spine in the everyday, habitual sitting position (OR = 1.19; CI = 1.05–1.34; p < 0.05) were associated with low-intensity LBP in female subjects. Additionally, the low intensity LBP were associated with the angles of the torso (OR = 1.14; CI = 1.01–1.29; p < 0.05) and the lumbosacral spine in the corrected sitting position (OR = 1.06; CI = 0.98–1.15; p > 0.05) and BMI (OR = 1.56; CI = 0.84–2.90; p > 0.05) in male subjects. Conclusion: Individual risk factors were associated with the low-intensity LBP only in females utilizing the PPT and the thoracolumbar angle in the habitual sitting position study factors. Men from the LBP group did not effectively correct the lumbosacral angle. Therefore, re-educated, self-corrected posture with specific postural training would be expected to improve proprioception in postural control capacity and result in decreasing pain.
Professional work in a sitting position and the low level of physical activity could be an important cause of overload symptoms formation in the lumbar spine.Objective of the work: The evaluation quantity of the low back pain threshold in patients without pain symptoms, with diversified level of physical activity.The research was conducted in group 40 subjects at the age of 20 to 25, IT specialists and physiotherapists. The participants could participate in the study under the condition that they have never had low back pain before. Patients from the experimental group were divided into 3 categories: active (13 patients), minimally active (18 patients) and inactive (9 patients). The division was made on the basis of The International Physical Activity Questionnaire – Short Form. The pain threshold was determined by an algometer, every time, on both sides of the spine at the level of L3 and in neutral point on hand, the test was performed twice.Analysis of variance ANOVA showed a main effect of level of physical activity for the pain threshold results on the pine left (F = 8.01; p < 0.05) and right site (F = 9.77; p < 0.05). There has not been demonstrated such effect for the pain threshold results around hand (F = 0.62, p > 0.05).Lower quantity of low back pain threshold occurs in the patients with inactive and minimal active declared physical activity level. This indicates the need of low back pain prevention, which could be achieved by increasing physical activity level. The people without pain symptoms do not show asymmetry of the pain threshold between the right and the left side.
Background:The study sought to assess the postural balance of office workers with spine dysfunctions before and after 5-month health training designed to improve postural stability. The essence of the work was also to know the relationship between balance exercises and the changes of spinal pain. Material and methods:Persons qualified for the study were those who had worked for, at least, 6 years in a sitting position for approximately 8 hrs/day, completed a full training cycle and fulfilled all participation criteria (women, n=15).Results: Exercising resulted in improved balance parameters, with attendance at 56% and the task completion rate of 60% in each week. Reduced asymmetry of sensitivity to pressure on paraspinal tissues at C4-C5 and L3-L4 was observed, even though the 21-week exercise cycle was insufficient to raise the pain threshold in the study participants.Conclusions: Multidisciplinary ambulatory rehabilitation (education + health training therapy) mobilises office workers and improves motricity, essential for a safe stable posture. Training reduces spine pain asymmetry in female office workers; however, the 5-month training programme lasting, on average, 35 min. twice a week is too short to reduce spinal pains significantly only by means of exercising.
