The purpose of this research was to compare the effects of activating muscle in the sample group of 30 people with lower back pain caused by sitting for work using different programs. Testing pain flexibility and flexion-relaxation phenomenon (FRP) before and after giving the activating muscle program. Data were collected using a pain questionnaire, sit and reach test, and electromyography (EMG) of back muscles to determine the FRP. The FRP is an indication of the ability to flexion-relaxation of two back muscles the erector spinae muscle and the multifidus muscle. Data before and after the experiment were analyzed using a one-way analysis of variance (ANOVA). Pairwise comparisons were made using the LSD method, and within-group data were compared using the t-test.
The results showed that all three groups had reduced pain and increased flexibility after the experiment. The control group and the thigh muscle activation group had significantly increased flexibility. The FRP decreased significantly between the control group and the thigh muscle activation group, and between the trunk muscle activation group and the thigh muscle activation group. Only the trunk muscle activation group showed a decrease in the FRP in the multifidus muscle, unlike the other groups. Therefore, in people who suffer from pain after sitting at work, it is important to increase the ability of the multifidus muscle to work to increase back stability by activating the trunk muscles and to increase muscle flexibility by activating both the trunk muscles and the thigh muscles. Modifying muscle function during sitting can help prevent back pain.
