Introduction: Elements of Dynamic Neuromuscular Stabilization (DNS), based on the developmental kinesiology of the first year of life, effectively alleviate lumbar pain by activating deep trunk stabilizers and regulating intra-abdominal pressure. Objective: The aim of the study was to investigate the knowledge and attitudes of physiotherapists regarding Dynamic Neuromuscular Stabilization in the context of lumbar pain syndrome. Participants (Materials) and Methods: The study involved 109 participants, including 78 bachelor's and 31 master's degree physiotherapists. The study was conducted in March and April using a custom-designed questionnaire distributed via Google Forms. The survey, disseminated through social media, comprised 22 questions categorized into three groups (general questions, attitudes, knowledge). Data were analyzed using Microsoft Excel and the Statistica software package, with t-tests for independent samples and chi-square tests applied. Results: Only 18 (16.5%) participants had completed the education. The majority of participants were employed in the public sector. No statistically significant differences were observed in knowledge test performance between those with bachelor's and master's degrees or with regard to completed education of Dynamic Neuromuscular Stabilization. Most participants have a positive attitude and incorporate elements of the therapeutic method in their work/internship. There was no statistically significant difference in the application of the elements of this method between physiotherapists working in the private sector compared to those in the public sector. The majority of previous scientific studies confirm the effectiveness of this method and support its integration in the treatment of lumbar pain. Responses to knowledge questions indicate a strong theoretical understanding of the basic principles of Dynamic Neuromuscular Stabilisation. Conclusion: Dynamic Neuromuscular Stabilisation is a crucial component in treating lumbar pain. Despite its proven effectiveness in numerous studies, the attitudes and knowledge of physiotherapists regarding DNS have not been previously explored in this context, which this study addresses for the first time.
