Risk of falls using the Biodex Balance System in non-faller patients with Parkinson Disease

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.

Introduction: Stroke is defined as the lack of blood supply to the brain, leading to rapid loss of brain function presenting with impairments such as muscle weakness, spasticity, lack of coordination, and proprioception loss. Both hydrotherapy and land-based therapy aim to target these aspects in the process of rehabilitation. The study aims to determine the effectiveness of water-based therapy on balance and gait of patients with stroke compared to land-based therapy. Methods: Data for this review were extracted from databases such as CINAHL, OTseeker, Ovid, PEDro, and PubMed (MEDLINE) and other sources such as Google Scholar. PRISMA guidelines were followed to exclude irrelevant studies. Only randomized controlled trials (RCTs) were included, and methodological quality was assessed using the PEDro scale. A meta-analysis of extracted data was conducted. Results: A total of 16 relevant RCTs were included for the review (n = 412 participants). All RCTs investigated the effect of water-based therapy compared to land-based therapy on balance and gait of patients with stroke. Meta-analysis of studies that used the Berg Balance Scale (BBS) as a primary outcome measure favored land-based therapy. Studies that used the Good Balance System (GBS) and the Biodex Balance System (BioBS) to measure the changes in anteroposterior sway and mediolateral sway favored water-based therapy. The overall pooled effect favored land-based therapy in improving gait parameters. Conclusion: Findings from meta-analysis support the effectiveness of land-based therapy in the improvement of balance and gait parameters of patients with stroke. However, the evidence for water-based therapy continues to be limited, and higher quality studies are required to determine the effectiveness of water-based therapy on patients with stroke, particularly on balance and gait.

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.

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 < .001), posteromedial (P = .002), and posterolateral (P = .03) directions and composite score of the SEBT in the NVIB group (P < .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.

Biodex Balance System

Locomotion over different terrain types, whether flat or uneven, is very important for a wide range of service operations in robotics. Potential applications range from surveillance, rescue, or hospital assistance. Wheeled-legged hexapod robots have been designed to solve these locomotion tasks. Given the wide range of feasible operations, one of the key operation planning issues is related to the robot balancing during motion tasks. Usually this problem is related with the pose of the robot’s center of mass, which can be addressed using different mathematical techniques. This paper proposes a new practical technique for balancing wheeled-legged hexapod robots, where a Biodex Balance System model SD (for static & dynamic) is used to obtain the effective position of the center of mass, thus it can be recalculated to its optimal position. Experimental tests are carried out to evaluate the effectiveness of this technique and modify and improve the position of hexapod robots’ center of mass.

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.
