PURPOSE: Down Syndrome (DS) is characterized by intellectual disability, hypotonia, and joint laxity. Physical disability can be an additional problem and manifests as reduced lower limb muscle strength and impaired balance. The objectives of this study were to characterize DS dynamic foot-ground contact area and to study its relationship with balance impairment among adolescents with DS. METHODS: Twenty-eight children and adolescents with DS and 28 non-DS adolescents/children were matched for age and sex. The Oxford Ankle Foot Questionnaire (parents’ version) was used to measure disability related to ankle/foot problems in all subjects. A pressure-sensitive mat was used to assess the contact area and arch index. Also, a Biodex balance system was used for measuring postural stability. RESULTS: There were significant differences between both groups in all domains of the Oxford Ankle Foot Questionnaire, overall contact area, and arch index (p <  0.05). Overall postural stability index was significantly decreased in subjects with DS (p <  0.05). There was a nonsignificant correlation between contact area and postural stability (p >  0.05). CONCLUSION: Adolescents with DS exhibited larger mid-foot and forefoot contact areas with respect to non-DS matched children. Impairment of balance in adolescents with DS is a multifactorial problem not related to changes in the foot contact area.

Stability Results

The aim of the study was to evaluate the effects of L-dopa on postural stability in Parkinson’s disease patients. In the study, we examined a group of 13 patients, members of the Parkinson’s Association. The majority of subjects were women: 8 (61.538%), while 5 (38.462%) were men. These were patients with advanced, idiopathic Parkinson’s disease. The study was performed at the Posturology Laboratory of the Faculty of Medicine and Health Sciences, UJK, Kielce (Poland). The duration of the illness was longer than 5 years. The daily L-dopa dose was between 600 and 1000 mg/d. Patients were tested for postural stability prior to taking the morning dose and again, 1 h after the 200-mg dose (Madopar 250 Tablets). The Biodex Balance System was applied in order to perform Postural Stability Testing. No statistically significant differences were found for the distribution of postural stability results before or after L-dopa administration. Nonetheless, it should be noted that all variables in the Postural Stability Test were slightly improved following L-dopa administration. The highest percentage (% Time in Zone) was noted in Zone A (the best), before (85.77%) and after L-dopa administration (95.23%). The highest % Time in Quadrant was in Quadrant IV (right posterior) both before (41.43%) and after L-dopa administration (49.54%). When comparing the distribution of postural stability variables before and after L-dopa administration, there were no significant differences between women and men.

This study aims to investigate the effects of varying toe angles at different platform settings on Overall Stability Index of postural stability and fall risk using Biodex Balance System in healthy participants and medial knee osteoarthritis patients. Biodex Balance System was employed to measure postural stability and fall risk at different foot progression angles (ranging from −20° to 40°, with 10° increments) on 20 healthy (control group) and 20 knee osteoarthritis patients (osteoarthritis group) randomly (age: 59.50 ± 7.33 years and 61.50 ± 8.63 years; body mass: 69.95 ± 9.86 kg and 70.45 ± 8.80 kg). Platform settings used were (1) static, (2) postural stability dynamic level 8 (PS8), (3) fall risk levels 12 to 8 (FR12) and (4) fall risk levels 8 to 2 (FR8). Data from the tests were analysed using three-way mixed repeated measures analysis of variance. The participant group, platform settings and toe angles all had a significant main effect on balance ( p ≤ 0.02). Platform settings had a significant interaction effect with participant group F(3, 144) = 6.97, p < 0.01 and toe angles F(21, 798) = 2.83, p < 0.01. Non-significant interactions were found for group × toe angles, F(7, 266) = 0.89, p = 0.50, and for group × toe angles × settings, F(21, 798) = 1.07, p = 0.36. The medial knee osteoarthritis group has a poorer postural stability and increased fall risk as compared to the healthy group. Changing platform settings has a more pronounced effect on balance in knee osteoarthritis group than in healthy participants. Changing toe angles produced similar effects in both the participant groups, with decreased stability and increased fall risk at extreme toe-in and toe-out angles.

Introdução: O envelhecimento provoca alterações fisiológicas e funcionais, declínio das funções e da capacidade funcional, compromentendo a autonomia e mobilidade, aumentando o risco de quedas; também está associado a alterações biológicas que comprometem a função muscular inspiratória. Existem estudos que mostraram que toda musculatura do tronco trabalha conjuntamente com a função de proteger a coluna e preservar o controle postural, incluindo os músculos inspiratórios, porém, o papel do diafragma na respiração sempre toma precedência sobre a função postural. Objetivo: Verificar a influência dos músculos inspiratórios na estabilidade postural de idosos. Métodos: Três idosos, realizaram avaliação da pressão inspiratória máxima (PImáx), em seguida no Biodex Balance System SD realizaram o 'Postural Stability Test' (PST), nas condições de respiração livre e com respiração através do equipamento Power Breathe®, com sobrecarga de 50% do valor da PImáx. Resultados: Nas oscilações anterior-posterior todos os idosos apresentaram maior índice de instabilidade no teste com aumento da demanda inspiratória e para as oscilações direita-esquerda dois idosos apresentaram maior índice de instabilidade nessa condição. Conclusão: O aumento na demanda inspiratória fornecido pelo dispositivo Power Breathe® foi capaz de alterar a equilíbrio de idosos, ainda que devemos considerar que para resultados mais esclarecedores seja necessário a realização de um estudo maior.

Introduction The purpose of this research was to examine the effect of occupation-based postural stability training on occupational performance and postural stability in visually impaired individuals. Method The research was designed as pre-test/post-test, with two groups (study group and control group). A total of 34 individuals with visual impairment were randomly assigned to the two groups. Participants were evaluated using a sociodemographic information form, the Biodex Balance System for postural stability, the Canadian Occupational Performance Measurement for assessing performance and satisfaction of occupations and the semi-structured interview form. The control group received only postural stability training with the Biodex Balance System and the study group received individualised occupation-based postural stability training with the Biodex Balance System BBS during a 12-week intervention (24 sessions). Results A statistically significant difference was found between the postural stability values of the study group and the control group when looking at pre and post-training measurements ( p < 0.05). It was observed that there was an improvement in the postural stability of the participants in both groups. There was a statistically significant increase in the occupational performance and satisfaction of participants in the study group ( p < 0.01). Conclusion Adding person-centred, meaningful and purposeful occupations into rehabilitation programmes that use technological devices increases functionality in activities of daily living.

Abstract A gradual loss of function in the balance system may begin in the fourth decade of life. The effects of this process become visible in old age, when problems with postural stability contribute to falls, making it an important social problem. Early detection of this dysfunction is essential for minimizing the risk of age-related falls, one of the main causes of hospitalization or even death in older adults. The aim of this study was to evaluate somatic factors that may result in the deterioration in postural stability and determine the age range in which the first changes in stability occur. The study included healthy non-sporting adults aged from 20 to 70 years. Four tests based on the Biodex Balance System were used to determine static postural stability, dynamic postural stability, risk of falling and stability limits. The obtained results showed that dysfunctions of dynamic balance appeared significantly earlier than static balance dysfunctions, i.e. as early as at 50 years of age, and then gradually increased. Higher BMI and the percentage and absolute fat content significantly increased the risk of falls and also adversely affected the results of dynamic stability tests.

Abstract The aim of the study was to assess postural stability of goalkeepers from the Polish national junior handball team. Eleven juniors of the Polish national handball team (age 16.82 ± 1.6 years, body height 191.27 ± 3.1 cm, body mass 88.41 ± 12.26 kg, BMI 24.18 ± 3.22 kg/m2) were selected for the study. The Biodex Balance System and AccuGait AM¬TI platform were used to evaluate postural stability. The obtained results indicated good postural stability of the subjects. During the Biodex Balance System platform tests, all subjects presented very good postural stability and maintained within Zone A. Postural sway was greater in the sagittal plane compared to the frontal one. Most of the participants demonstrated slight backward tilts, but maintained in Quadrant IV. During the AccuGait AMTI platform trial, Path Length and Average COP Speed significantly increased in the test performed with closed eyes. Furthermore, there were significant positive correlations between the number of variables obtained during the Biodex Balance System and AccuGait AMTI tests. Proper and stable posture are necessary conditions to be met to carry out most free movements and locomotion. They play a significant role in the game of a handball goalkeeper and for that reason, postural stability testing of handball goalkeepers is an important element of coordination training. Thus, the use of postural stability exercises implementing the biofeedback method on stabilo and dynamometric platforms is practical and justifiable.
