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.

Research background. Equilibrium and posture impairment is a common cause of collapse in individuals experiencing traumatic brain injury, which limits patient autonomy and independence in daily activities. Therefore, the recovery of balance is one of the primary goals of rehabilitation for individuals following the traumatic brain injury (Llorens et al., 2013). The aim was to determine the relationship between sensory integration, postural stability and fall risk assessment parameters using physiotherapy for individuals with traumatic brain injury. Methods. The study involved 16 people with traumatic brain injury. The subjects were divided into two groups – the frst one (n = 8) and the second one (n = 8). The frst group was taking 30 minutes regular physiotherapy and 30 minutes balance training with Biodex Balance System, second group – 30 min. regular physiotherapy and 30 minutes regular exercises for balance. Results. Changes in the postural stability index, anterior /posterior and medial/ lateral fluctuation indexes, fall risk stability index and clinical sensory integration test index in both groups did not change statistically signifcant (p > 0.05). A strong, statistically signifcant direct relationship was found in the frst study group between the postural stability index and the fluctuation of the anterior /posterior index changes (r = 0.922; p = 0.001). Conclusions. Physiotherapy using the Biodex Balance System and the usual physiotherapy is equally effective in developing postural stability, sensory integration, and fall risk. The link between many of the studied indicators shows that postural stability, sensory integration and the risk of falls are related.Keywords: traumatic brain injury, sensory integration, postural stability, fall risk, physiotherapy.

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.

Context:  Deficits in the propioceptive system of the ankle contribute to chronic ankle instability (CAI). Recently, whole-body–vibration (WBV) training has been introduced as a preventive and rehabilitative tool. Objective:  To evaluate how a 6-week WBV training program on an unstable surface affected balance and body composition in recreational athletes with CAI. Design:  Randomized controlled clinical trial. Setting:  Research laboratory. Patients or Other Participants:  Fifty recreational athletes with self-reported CAI were randomly assigned to a vibration (VIB), nonvibration (NVIB), or control group. Intervention(s):  The VIB and NVIB groups performed unilateral balance training on a BOSU 3 times weekly for 6 weeks. The VIB group trained on a vibration platform, and the NVIB group trained on the floor. Main Outcome Measure(s):  We assessed balance using the Biodex Balance System and the Star Excursion Balance Test (SEBT). Body composition was measured by dual-energy x-ray absorptiometry. Results:  After 6 weeks of training, improvements on the Biodex Balance System occurred only on the Overall Stability Index (P = .01) and Anterior-Posterior Stability Index (P = .03) in the VIB group. We observed better performance in the medial (P = .008) and posterolateral (P = .04) directions and composite score of the SEBT in the VIB group (P = .01) and in the medial (P &lt; .001), posteromedial (P = .002), and posterolateral (P = .03) directions and composite score of the SEBT in the NVIB group (P &lt; .001). No changes in body composition were found for any of the groups. Conclusions:  Only the VIB group showed improvements on the Biodex Balance System, whereas the VIB and NVIB groups displayed better performance on the SEBT.

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.

The objective of this study was to evaluate the relationship between the anthropometric factors of height, body mass, body mass index and postural balance and to compare the balance indices between genders in the upright standing position, in healthy adult subjects under conditions of instability. Forty individuals were subjected to functional tests of body stability using the Biodex Balance System, and the resulting indices were correlated with body mass, height, and body mass index, and also compared between genders. Body mass was the main anthropometric factor that influenced variations in postural balance, with a high correlation between groups and with all variables. A linear regression analysis showed that body mass associated with BMI explained 66% of the overall stability, and body mass explained 59% of the anteroposterior stability index and 65% of the mediolateral stability index. In the female group, body mass explained 72% of the overall balance, 66% of the anteroposterior, and 76% of the medio-lateral stability index. Increased body mass requires greater movements to maintain postural balance. Height and BMI presented moderate correlations with balance. Women showed less movement than men on the Biodex Balance System.

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.
