This paper presents methods and research for the development of an unstable seat. The dissertation reviews the impact of prolonged sitting position on lower back pain, the use of ergonomic and unstable chairs in the workplace, and their impact on the human spine. The work reviews various: electromyography, electroencephalography, and three-dimensional (3D) movement analysis, which are widely used in the analysis of human physiological and biomechanical parameters. These methodologies were used in the study of individuals in a seated position and later in the development of a prototype of an unstable seat. The main goal of the research was to create an innovative unstable seat, which increases the activity of the trunk muscle and brain cortex. It has been scientifically proven that long-term sitting causes musculoskeletal disorders, atrophy of deep spinal muscles, muscle fatigue and reduced mobility. Therefore, during the scientific research, a prototype of the unstable seat was created, which was subjected to mechanical analysis and a pilot study. The created prototype has great practical value, it can be applied in the work environment as a prevention against back pain, and it can also be an excellent tool to activate the deep back muscles and thus reduce the negative impact of long-term static sitting position on our spine. |
