Assessment of selected muscles reactivity in the lower spinal segment

Background: Lumbar spine pain is now a common affliction. In 90% of cases, the pain is of ambiguous andmulticausal etiology, described as non-specific lower back pain (NLBP). Various models of this dysfunctionwere examined. The most popular model presents the pain as a result of an insult and secondary to changesin tension and lumbar muscles degeneration. There is no unequivocal solution concerning the cause of lumbarspine pain in the literature.Aim of the study: To examine the differences in muscles reactivity in the lumbar region in cases who sufferfrom lumbar spine pain in comparison to otherwise healthy controls.Material and methods: In total, 50 participants (24 men and 26 women) aged 18–45, including 24 peoplewith pain, and 26 without ailments were included in the study. The visual analogue scale was used to measurepain intensity. The participants were assessed to determine the reactivity of the soft tissues of the lumbarpart of the body. Selected muscles of this area were examined using a myotonometer, which shows five parametersrelevant to viscoelastic tissues.Results: There were significant differences in the level of the pain (p
