One-legged stance sway of older adults with and without falls
PloS one, 2018
Postural instability is a common problem among older people, and it is associated with mobility impairments, activity limitation and fear of falling. The evaluation of postural control can contribute to the early detection of balance deficits and help health professionals to manage this problem to prevent falls in older adults. The aim of this study was to identify center of pressure cut-offs to differentiate between older adults with and without falls in the past 12 months. The participants were 170 older adults (mean age 67 years, 50 fallers and 120 non-fallers). Center of pressure area and sway velocity in the anterior-posterior and medio-lateral directions were assessed using a force platform during three 30s one-legged stance trials with eyes open. The mean across trials was used for analysis. The time-limit (how long the participant was able to stay in one-legged stance, up to 30s) was also assessed. Fallers had poorer postural control than non-fallers (effect size ≥ 0.52, P &...

Balance impairs with aging and may cause mobility limitations and functional decline. We aimed to evaluate postural balance and PADL in physically independent older adults with different levels of exercise capacity. One hundred fifty seven physically independent individuals, aged 60 years or older were evaluated. Postural balance assessment was performed during one-legged stance test using a forceplatform and maximum exercise capacity with the incremental shuttle walking test (ISWT). PADL was assessed subjectively by the modified Baecke questionnaire and objectively using a pedometer. Based on the performance achieved in the ISWT, according to the percentage of the predicted value, the older adults were separated into 3 groups: low performance group (LP group, ISWT < 80% predicted, n = 32, 19 women), normal performance group (NP group, 80 ISWT 100% predicted, n = 30, 22 women) and high performance group (HP group, ISWT > 100% predicted, n = 95, 67 women). The HP group showed better postural balance when compared to LP groups (p < 0.001) and also higher levels of PADL measured with pedometer (p < 0.001). There was a modest correlation (r = 0.45) between exercise capacity and PADL in the LP group and a weak correlation between exercise capacity and balance (r = À28) in the HP group. Physically independent older adults with more preserved exercise capacity have better postural balance and higher levels of PADL in comparison to those older adults who show a poorer condition in terms of exercise capacity. ß

International journal of physical education, sports and health, 2020
Background: Balance is a fundamental ability of human movement. Aging and all neuromusculoskeletal disorders result in decreased postural control and falls. Therapeutic exercise is an effective tool to improve postural control. Balance exercise programs have proved to be helpful for older adults. This study is to measure the level of physical activity in older adults and determine the effect of a balance exercise program to improve on postural control in older adults. Objective: The objective of the study is to measure the level of physical activity in older adults and determine the effect of a balance exercise program to improve on postural control in older adults. Methodology: An interventional study was conducted to find the effectiveness of balance exercise in older adults to improve postural control. Convenient samples of 30 older adults < 50 years with normal BMI were assessed and underwent intervention process based on inclusion criteria. International Physical Activity Questionnaire was used to assess level of physical activity in subjects and Tinetti Performance Oriented Mobility Assessment used before and after exercise program to assess balance &gait. The exercise was given of weekly thrice 1 hour session over a 4 week period. Result: Statistical analysis was done using descriptive statistics and paired t tests. Mean and standard deviation of the collected data of POMA are 21.76 +3.69 in before and 26.86 +1.4 in after treatment. The results of IPAQ in collected data are high and moderate level of physical activity. The t tests show significant improvement in pre and post treatment (before and after balance exercise). i.e. POMA-T = 7.921(p=0.000), POMA-G = 4.527(p=0.000) and POMA-B = 9.279(p=0.000). Conclusion: This study concludes that balance exercise program that improved postural control in older adults with normal BMI. And these interventions are help to reduce the risk of falls. The balance exercise program was given only for 4 week period.

Background. Balance disorders increase considerably with age due to a decrease in posture regulation quality, and are accompanied by a higher risk of falling. Conversely, physical activities have been shown to improve the quality of postural control in elderly individuals and decrease the number of falls. The aim of this study was to evaluate the impact of two types of exercise on the visual afferent and on the different parameters of static balance regulation.
Comparison of Postural Sway in Young and Geriatric Individuals in Standing Posture on Balance Master
2015
Background: This study is intended to find out the effect of aging on postural sway in older individuals. While performing ADL activities, requires performing more than one task simultaneously. In this study we are comparing between two population adults and geriatric. As the age increases, because of the degenerative changes balance decreases. Methodology: In this study, standing posture is used for balance examination with the use of balance master. Healthy young and older individuals are taken for examination and on balance master, postural sway was measured. Sensamove balance master has (0.510 – 0.815) intraclass correlation coefficient reliability and (0.535 – 0.705) pearson correlation coefficient validity as compared to gold standard force plate. Result: This study showed balance performances, in adults 97.25% and in geriatric 88% in standing task, 91.75% in adults, front deviation was 0.13 o and in geriatric, 0.67 o; in adults, back deviation was0.27 o and in geriatric, it w...
Age-Related Changes in Postural Control in Physically Inactive Older Women
Journal of geriatric physical therapy (2001), 2017
The maintenance of postural control is influenced by the complexity of a given task. Tasks that require greater attention and cognitive involvement increase the risk of falls among older adults. The aim of the present study was to evaluate the adaptation of the postural control system to different levels of task complexity in physically inactive young and older women. A cross-sectional study was conducted with adult women classified as physically inactive based on the results of the International Physical Activity Questionnaire. The participants were 27 young (20-30 years of age) and 27 older (60-80 years of age) women. Sway velocity of the center of pressure in the anterior-posterior and medial-lateral directions was calculated using a force plate under 6 conditions: standing directly on the force plate or on a foam placed over the force plate, eyes open or closed, and task complexity with and without the foam. A 2-way analysis of variance revealed that sway velocity increased in b...
Static postural balance in healthy individuals: Comparisons between three age groups
Motriz: Revista de Educação Física, 2014
The aim of the study was to compare static postural balance of healthy individuals of three age groups in different conditions of support and vision. Seventy one individuals, divided into 3 groups, were analyzed: young group (YG: 22.2 ± 2.1 years), middle aged group (MAG: 50.7 ± 5.7 years) and older individuals group (EG: 66.8 ± 5.4 years). Their balance was tested on a force platform, under 3 support and 3 visual conditions. Measures included: total (TD), anterior-posterior (APD) and mediolateral displacement (MLD) of the center of pressure (CoP). ANOVA revealed significant differences for interactions between group X support conditions and group X visual conditions for the 3 variables (p<0.01), with greater displacements for the MAG and EG groups during single-leg stance with partial and occluded vision (p<0.05). Static postural balance decreased over time in healthy individuals, and conditions of support and visual negatively affected balance with the increment of age.

fall-related injuries constitute major health risks in older individuals, and these risks are projected to increase in parallel with increasing human longevity. Impaired postural stability is a potential risk factor related to falls, although the evidence is inconclusive, partly due to the lack of prospective studies. This study aimed to investigate how objective measures of postural sway predict incident falls. this prospectively observational study included 1,877 community-dwelling individuals aged 70 years who participated in the Healthy Ageing Initiative between June 2012 and December 2015. postural sway was measured during eyes-open (EO) and eyes-closed (EC) trials using the Wii Balance Board. Functional mobility, muscle strength, objective physical activity and cognitive performance were also measured. Participants reported incident falls 6 and 12 months after the examination. during follow-up, 255 (14%) prospective fallers were identified. Division of centre of pressure (COP)...

Different types of exercise are indicated for the elderly to prevent functional capacity limitations due to aging and reduce the risk of falls. This study aimed to evaluate the effect of three different exercises (mini-trampoline, MT; aquatic gymnastics, AG and general floor gymnastics, GG) on postural balance in elderly women. Seventy-four physically independent elderly women, mean age 69±4 years, were randomly assigned to three intervention groups: (1) MT (n=23), (2) AG (n=28), and (3) GG (n=23). Each group performed physical training, including cardiorespiratory, muscular strength and endurance, flexibility and sensory-motor exercises for 12 weeks. To determine the effects on each intervention group, five postural balance tasks were performed on a force platform (BIOMEC 400): the two-legged stand with eyes open (TLEO) and two-legged stand with eyes closed (TLEC); the semi-tandem stand with eyes open (STEO) and semi-tandem stand with eyes closed (STEC) and the one-legged stand.
