Low back pain is one of the most common health problems nowadays. In the individuals with low back pain numerous alterations in neuromuscular functions of the trunk can be observed. Aetiology of low back pain is complex and often depends on psychosomatic status. Therefore, it is important to understand the biomechanical characteristics, which are altered in low back pain patients. Objective assessment of these alterations allows detection of acause or a consequence of low back pain. Even though studies demonstrated changes in neuromuscular functions of the trunk in low back pain patients, is this kind of assessment limited to the research and is not used in a clinical practice. The purpose of this paper is to present the technical characteristics of the integrated measurement system for valid and objective assessment of the trunk neuromuscular functions, which was developed as part of the research project carried out between the university and the industry. We also empirically and graphically present a case study of one whole measurement on a young healthy person. At the end of the paper we discuss practical solutions for health and sport institutions when treating low back pain patients.

There is a grooving interest in postural reflex reaction assessment in relation to low back pain in research and clinical practice. The purpose of this study was to assess reliability of sudden loading test. Averaging of 18 consecutive trials was necessary to achieve excellent intra session (ICC ) 0.75) and god inter-session (ICC ) 0.60) reliability in most of the analyzed muscles. Averaging more consecutive repetitions, than used in previous studies, would be recommended.

When perturbations posture are predictable central nervous system induce anticipatory postural adaptations which precede the perturbation. The purpose of the study was to investigate if there is a connection between the strength of the trunk muscles and the onset timing of the trunk stabilizing activity of the muscles. Results showed moderate negative correlation between the anticipatory activation of trunk extensors and strength of the trunk extensors (r = -0.619; p = 0.011) and the trunk flexors (r = -0.498; p = 0.049). Results showed, that 38.2% of the variance of delay, between the stabilizing muscle activation of the trunk and the beginning of the forward arm movement, can be explained by the strength of the trunk extensor muscles.
