Academic supervisor: assistant PhD Jurga Indriūnienė, Vilnius University, Faculty of Medicine, Institute of Health Sciences, Department of Rehabilitation, Physical and Sports Medicine. Keywords: Contemporary dancers, trunk stability, lower limb, hypermobility, muscle strength, risk of injury, associations, relationship. The aim of research work: To assess the relationship between trunk stability, lower limb functions and injury risk in contemporary dancers. Tasks of work: 1. To assess the trunk‘s stability, lower limb hypermobility and the strength of the hip flexor, gluteus maximus, anterior and posterior thigh muscles in contemporary dancers. 2. To assess the risk of injury in contemporary dancers. 3. To analyse the relationship between trunk stability, lower limb hypermobility and hip flexor, gluteus maximus, anterior and posterior thigh muscle strength and risk of injury amongst contemporary dancers. Materials and methods. The study was conducted in 2024 at the Department of Rehabilitation, Physical and Sports Medicine, Institute of Health Sciences, Faculty of Medicine, Vilnius University, and in the subjects' rehearsal rooms. The participants were contemporary dancers who agreed to participate in the study and had no acute injuries or pain. 27 contemporary dancers participated in the study. They ranged in age from 18 to 35 years. The following methods were used: DNS tests were used to assess trunk stability, the lower limb assessment test was used to assess lower limb hypermobility, the isometric strength of the hip flexors, gluteus maximus, anterior and posterior thigh muscles were tested with a hand-held dynamometer and the risk of injury was assessed with the Functional Movement Scale methodology. Statistical analysis of the data was performed using SPSS 19.0 statistical analysis package and Microsoft Office Excel 2016. Results. Hypermobility of the lower limb was found in 8 subjects. The estimated effect size was significant. The scores for trunk stability ranged from 131 to 183. No significant differences were found between the right and left limbs when muscle strength was assessed. 6 subjects were at increased risk of injury. The estimated effect size was significant. No statistically significant correlations were found between trunk stability, lower limb hypermobility and injury risk (p>α). These variables did not correlate with the isometric strength of the studied muscles (p>α). Significant correlations were found between the isometric forces of some of the muscles studied (p<α). The strongest correlations were found between the isometric force of the right and left side muscles (p<α). Conclusions. 1. Although no subject reached the maximum score for trunk stability and 30% of subjects had lower limb hypermobility, there were no significant differences between right and left leg muscle strength. 2. 22% of modern dancers were at increased risk of injury. 3. The hypothesis was not confirmed. No significant correlations were found between trunk stability, lower limb hypermobility, muscle strength and risk of injury. In contrast, the strongest associations were found between right and left isometric muscle strength. |
