Introduction: People experiencefrom neck pain, headaches, kyphosis and back pain while working with computers, and these issues seem to be increasing with the advancement of technology. The aim of the present study was to investigate the effect of 10 sessions using simple and sensory thoracolumbosacral brace on lower limb muscle activities in kyphosis patients during typing.
Methods: This study was a semi-experimental and laboratory investigation. The statistical population of the study was people with kyphosis in Ardabil city. The sample consisted of 30 male employees with kyphosis who were randomly divided into users of the sensor brace and users of the simple brace groups. The electrical activity of the upper limb muscles was recorded by the electromyography system during typing in both pre and post-test. Both groups used brace during ten weeks in their training sessions. All statistical analyses were done using SPSS software, and a two-way ANOVA analysis was conducted with a significance level of 0.05.
Results: The results demonstrated significant main effects of "time" for extensor digitorum muscle (P=0.016; d=0.180), anterior deltoid (P=0.014; d=0.196), middle deltoid (P=0.001; d=0.447) and trapezius (P=0.046; d=0.116) activity during typing. Findings showed significant main effect of group for the anterior deltoid (P=0.008; d=0.223) and posterior deltoid (P=0.013; d=0.201). Furthermore, significant group-by-time interactions were found for superficial extensor digitorum muscle (P=0.019; d=0.189), triceps (P=0.001; d=0.310), middle deltoid (P=0.044; d=0.133) and posterior deltoid (P=0.001; d= 0.554) activity during typing phase.
Conclusion: The decreased electromyographic activity of the muscles when using thoracolumbosacral braces in employees with kyphosis confirms the effectiveness of this intervention. However, further study is needed to better establish this issue.
