This study aimed to evaluate professional footwear comfort, functionality and style as well as their relationships with the foot structure among nurses. Methods: We examined 120 clinical nurses aged 40–50 years, occupationally active, wearing specific type of footwear at work for a minimum of 7 h a day, for 5 days prior to the research. The study relied on the CQ-ST podoscope for measurements of foot. Perception of footwear comfort, functionality and style scales were also used in the research. The results were analysed with the use of Mann–Whitney U-test and Spearman’s rank correlation. Results: Statistically significant negative associations were found between right and left foot length and overall comfort of footwear ( p = 0.045, p = 0.045) as well as between right and left foot width and arch height ( p = 0.015, p = 0.028). Heel angle positively correlated with safety ( p = 0.008, p = 0.050), ease of donning and doffing ( p = 0.001, p = 0.004), as well as shoe style ratings ( p = 0.047). Variables determining shoe comfort were positively correlated with most shoe functionality characteristics as well as with shoe style (p < 0.05). Conclusions: Tested medical footwear meets the requirements of nurses in terms of comfort, functionality and aesthetics, and the studied features of footwear can be a useful guideline for the selection of shoes for representatives of this professional group. These footwear can be an element of workwear, and even, in the case of women with transverse flat feet – an alternative to ordinary utility shoes. There is a need to consider different widths for the same length size in medical footwear designs.

Purpose: The aim of this work was the assessment of postural stability at different heights as well as in natural standing position and during tandem stance in female athletes who practice artistic gymnastics. Methods: The study comprised 34 athletes aged 8–12, practicing artistic gymnastics at a sports club „Korona Kraków”. The research tool was CQ-Stab 2P two-platform posturograph. The elevation was achieved using the Light SPL platform. The data were analyzed based on Wilcoxon signed-rank test and Spearman’s rank correlation. Results: The height at which the posturograph was set differentiated the path length of the statokinesiogram, both in the natural stance ( p = 0.035) and tandem stance (p = 0.012). When the posturograph was placed on the floor, statistically significantly higher sway area delimited by the COP point (p < 0.001), statokinesiogram path length (p < 0.001), mean amplitude of COP displacement (p < 0.001) and mean frequency of COP displacement (p = 0.048) values were recorded in the tandem stance position. On the other hand, when the posturograph was placed on a landing, statistically significantly higher sway area delimited by the COP point (p < 0.001), statokinesiogram path length (p < 0.001) and mean frequency of COP displacement (p < 0.001) values were recorded in the tandem stance position. Conclusions: Increasing height was accompanied by deterioration of stability indices. Postural stability improves with training experience.

The study aimed to assess the formation of the spinal anteroposterior curvatures in people practicing ballroom dancing. Methods: The study group comprised 98 people practicing ballroom dancing (58 W, 40 M; aged 35–45 years). Digital inclinometer “Baseline” was used as primary research tool. The data were analyzed based on Student’s t-test, Mann–Whitney U-test and Pearson Chi-square test. Results: Statistically significant inter-gender differences were in the values of angles determining inclination of lumbosacral section of the spine ( p < 0.001), the lumbar lordosis curvature ( p < 0.001) as well as the compensation ratio ( p = 0.002). Statistically significant dependences between the types body posture and gender ( p = 0.005) were noted. Conclusions: Women practicing ballroom dancing are distinguished with increased inclination of lumbosacral section of the spine and deeper lumbar lordosis, while men are characterized with shallowed lumbar lordosis. Women are more likely to have lordotic body posture while men are characterized by balanced body posture. The prevalence of body posture subtypes is not dependent on gender.

The aim of the study was to compare the values of selected stability indices registered in the trials in standing with eyes open and without visual control, and in handstand in athletes practicing artistic gymnastics at the highest level of advancement. Methods: The study included 20 athletes practicing artistic gymnastics. The research tool was posturograph CQ-Stab 2P. The results obtained in individual trials were compared using Friedman repeated measures analysis of variance by ranks and then subjected to Dunn post-hoc test with Bonferroni adjustment. Results: Statistically significant differences in the values of stability indices recorded in individual samples were found. Exceptions are the results obtained in the trials with eyes open and without visual control with regard to the size of the surface area delineated by the COP ( p = 0.173) and the frequency of corrective reactions ( p = 0.464), as well as the length of the statokinesiogram path in the mediolateral direction ( p = 0.342), mean velocity of COP movement in the mediolateral direction ( p = 0.246), maximal amplitude of the COP in the mediolateral direction ( p = 0.342) and number of COP displacements in the mediolateral direction ( p = 0.246). Conclusions: In seniors, disabling visual control during free standing as well as adopting a handstand position result in deterioration of the stability indices, which is a resultant of the COP displacement in both directions as well as in the anteroposterior direction. Lack of differences in the values of stability indices in the mediolateral direction suggest that in a free standing position, seniors practicing artistic gymnastics control the movement of the center of foot pressure in the mediolateral direction and eye control is not important for the stability of the body in the frontal plane.
