Opis:
The osteoarthritis of the hip dominant symptom is pain that leads to disability and to postural and gait disorders. The aim of this study was to analyze postural stability and its impact on disability and pain. The study population consisted of 60 patients and control group of 30. Group 1 (n = 30) included patients with unilateral coxarthrosis, aged 56.2 (±12.3) years, BMI 25.17 (±2.87) kg/m2. There were 16 men (53.3%). The mean age of patients in group 2 (n = 30) with bilateral coxarthrosis was 62.3 (±12.1) years; the mean BMI was 24.87 (±2.06) kg/m2. There were 15 men in this group (50%). The patients were evaluated using the WOMAC, the Harris Hip Score, VAS and the Biodex Balance System. Both study groups had stability index results different than the control group. There was a significant correlation between the stability indexes and BMI. VAS correlated with the M-L plane variance. In group 2, there were significant differences related to disability for the disability scales for all measured parameters. Balance disorder is a basic parameter found in coxathrosis. There is a statistically significant correlation between balance disorders and BMI, VAS and functional scales.

Opis:
Purpose: It is still not clear which parameters of sound are the most significant for body reactions and whether the way of sound reception plays a role in body control. The purpose of this study was to determine the influence of frequency, spectrum and loudness of sounds on posture control in healthy women and men. Methods: The study subjects were 29 young adults who were submitted to a 60-second standing test in the bipedal stance on the force platform (AMTI). During the tests, 3 sinusoidal sounds with various timing and 2 musical sounds (guitar and piano) of the frequency 225 Hz, 1000 Hz and 4000 Hz were applied through headphones. The centre of pressure (COP) amplitude was registered. The sway area and COP mean velocity were computed. Results: It was found that high frequency sounds contributed to a significant decrease of sway area values. No significant influence of low frequency sounds on posture control was observed. The influence of the sound spectrum (timbre) on posture control is limited; only the crescendo spectrum improves the body stability in the bipedal stance and not the music spectrum as guitar and piano. The loudness of sound, although extremely high, is not the cause of postural control changing in relation to lower loudness. No effect of gender was found in terms of body stability under different sound conditions. Conclusion. Based on the results, it can be argued that, in general, in a bipedal stance in terms of stability high sound frequency improves posture control, whereas sound spectrum and intensity show a limited impact.

Opis:
Identification of factors that affect postural stability may help to improve diagnostic accuracy and enhance the quality of treatment and rehabilitation. This study sought to assess the relationship between postural stability parameters and anthropometric factors of persons with hearing impairment (HI). Methods: The study included 128 individuals – 42 subjects with HI and 86 without HI (healthy controls). Research methodology included an interview and a medical examination, anthropometric measurements and stabilometric tests on platforms with stable and unstable surfaces. Results: In the group of female study participants with HI, significant correlations were only noted between body height and the Fall Risk Index (FRI). In the group of male subjects with HI, the study revealed significant correlations between FRI and body mass, BMI, % MM (muscle mass percentage) and % FAT (fat percentage). Moreover, moderate correlation was found between COP path with eyes open and body mass, while high correlation was observed between COP path with eyes open and BMI, % MM and % FAT. No significant correlation was noted between FRI and body height in men with HI. Conclusions: The examination of correlations between postural stability and body build of persons with HI did not confirm the effects of body height on postural stability in the examined group of individuals with HI, but revealed a greater influence of somatic parameters (body mass, BMI, % MM, % FAT) on postural stability in hearing-impaired men.

Opis:
The purpose of this work was to assess the differences of the values of body posture indices, measured with the Moire’s method, between girls and boys aged 13 and the relationships of these values with the results of the Y-Balance Test. Methods: The study involved a group of healthy volunteers attending junior high schools in Cracow. The group consisted of 20 girls and 35 boys. Basic somatic parameters were measured within this work: body height and weight. Body posture was assessed according to the general methodology of the Moire’s technique and 14 body posture indices were obtained as a result: 6 in the sagittal plane, 1 in the axial plane and 7 in the coronal plane. Postural stability was assessed with the Y-Balance Test (YBT). Results: The studied girls and boys had practically the same body posture – statistical differences were found only in 3 out of 14 assessed indices measured with the Moire’s technique. Scoliosis was found in as many as 51% of the subjects, however, mean values of deviations from the C7-S1 line were not large. Conclusions: In the group of girls, the set of blades (below – above) was statistically significantly correlated with the global YBT result for the right inferior extremity, and in the group of boys – the set of the waist triangles (below – above) was statistically significantly correlated with the global YBT results for the right and left inferior extremities.
