Purpose: Balance training (BT) studies in children reported conflicting results without evidence for improvements in children under the age of 8. The aim of this study therefore was to compare BT adaptations in children of different age groups to clarify whether young age prevents positive training outcomes. Methods: The effects of 5 weeks of child-oriented BT were tested in 77 (38 girls and 39 boys) participants of different age groups (6–7 y, 11–12 y, and 14–15 y) and compared with age-matched controls. Static and dynamic postural control, explosive strength, and jump height were assessed. Results: Across age groups, dynamic postural sway decreased (−18.7%; P = .012; ) and explosive force increased (8.6%; P = .040; ) in the intervention groups. Age-specific improvements were observed in dynamic postural sway, with greatest effects in the youngest group (−28.8%; P = .026; r = .61). Conclusion: In contrast to previous research using adult-oriented balance exercises, this study demonstrated for the first time that postural control can be trained from as early as the age of 6 years in children when using child-oriented BT. Therefore, the conception of the training seems to be essential in improving balance skills in young children.

AbstractMaking assessments regarding postural control and balance is very important for injury prevention in soccer. However, there has been no study that has associated postural control variables with branch-specific technical properties in a game. The aim of the present study was to determine the relationships between variables designating postural control levels and technical performance variables in different (1:1, 2:2 and 3:3) small-sided games (SSGs). Sixteen trained male amateur soccer players volunteered to take part in the study (age 17.2 ± 1.02 years, body height 176.25 ± 0.07 m, body mass 67.67 ± 13.27 kg). Following familiarization sessions, postural control was evaluated using one-leg and both-leg quiet-stance positions by measuring postural sway with a Tekscan HR Mat™ in anterior–posterior and medial–lateral directions. Later, 1:1, 2:2 and 3:3 SSGs were performed at two-day intervals and the technical variables specified for each game were analyzed. A Spearman’s rank-order correlation analysis demonstrated the relationship between postural control and soccer-specific technical variables in 1:1 (r-values ranging from 0.582 to 0.776), 2:2 (rvalues ranging from 0.511 to 0.740) and 3:3 (r-values ranging from 0.502 to 0.834) SSGs. In addition, a Wilcoxon signed rank test revealed differences between SSGs in terms of several variables. The results of the study showed that higher postural control levels are among the important variables that affect success in the performance of technical skills under rival pressure and suddenly changing conditions. Therefore, it is recommended that in addition to its use for injury prevention purposes, balance training should be conducted to improve branch-specific technical skills and to increase the levels of their successful performance in a game.

Before And After

Balance training represents a critical part of the rehabilitation process of individuals living with multiple sclerosis (MS) since impaired postural control is a distinctive symptom of the disease. In recent years, the use of the Nintendo Wii system has become widespread among rehabilitation specialists for this purpose, but few studies have verified the effectiveness of such an approach using quantitative measures of balance. In this study, we analyzed the postural sway features of a cohort of twenty-seven individuals with MS before and after 5 weeks of unsupervised home-based balance training with the Wii system. Center of pressure (COP) time-series were recorded using a pressure platform and processed to calculate sway area, COP path length, displacements, and velocities in mediolateral (ML) and anteroposterior (AP) directions. Although the results show a significant reduction in sway area, COP displacements, and velocity, such improvements are essentially restricted to the ML direction, as the Wii platform appears to properly stimulate the postural control system in the frontal plane but not in the sagittal one. Available Wii games, although somewhat beneficial, appear not fully suitable for rehabilitation in MS owing to scarce flexibility and adaptability to MS needs and thus specific software should be developed.

The Relationship

The present study is designed to address the relationship between postural sway and balance training. We compared postural sway in a group of trained dancers to a group of physically fit, untrained participants (control group) in order to assess enhanced postural control with balance training, particularly under challenging balance conditions. We varied the difficulty of postural control by using two surface conditions (rigid surface, foam surface) and two visual conditions (eyes open, eyes closed), factorially combined. The data were evaluated using 1-between (group) × 2-within (vision and surface) analyses of variance (ANOVA). The three dependent variables were the standard deviation of the COP time series in the anterior-posterior (AP) and medial-lateral (ML) axes, and the COP path length. Significant main effects were found for surface and vision and the surface*vision interaction in all conditions. Significant group differences were found in the AP and ML axes. The results of this study indicate that balance training enhances the control of posture. Thus, it may be useful to provide balance training to workers who must operate under conditions that threaten balance.

Background: The majority of people who work as tea plantation pickers are powerful. They carry heavy loads of tea on their backs while the roads are quite dangerous and sometimes cause problems. A balance training program has proven to reduce postural sway, increasing leg muscle strength and improving balance strategies. Objective:The aim of this study was to determine the effect of  Vladimir Janda balance training methods with an external load on postural sway and leg muscle strength of tea pickers. Methods: The study design used was quasi-experimental with a randomized control group pretest-posttest design. Subjects were tea pickers consisting of a productive age group of 15 people and 15 people as a control treatment group. The Vladimir Janda method balance exercises were conducted over five weeks consisting of 5 phases. Phase I-IV were carried out 5 times a week, while the V phase was done 3 times a week and each session lasted 15 minutes. Postural sway was measured with a posturometer. Leg muscle strength was measured by a back-leg dynamometer. The statistical tests used were Independent T-test and the Mann-Whitney test. Results:The statistical test for the control and treatment groups using the Mann-Whitney test showed p = 0.001, meaning no external load effects on postural sway. Independent t-test showed p = 0.000, meaning there are differences in the effect between the treatment and control groups after being given balance exercises to increase leg muscle strength. Logistic regression test results obtained the ROC value of 0.917, meaning the Vladimir Janda balance training can affect the postural sway and knee extensor muscle strength by 91.7%. Conclusion: The Vladimir Janda balance exercise method can reduce postural sway and increase the strength of knee extensor muscles and ankle flexor Dorsi muscles. External loads can affect the postural sway.

In order to study voluntary and reflexive mechanisms of postural control, young and elderly persons were given large-fast and small-slow ankle-rotation postural disturbances while standing on a movable platform capable of measuring ground reaction forces. Large-fast rotations were employed to activate long-loop reflexes, and small-slow rotations were employed to tap the higher level sensory integration aspects of postural control. Overall, the elderly persons exhibited more perturbation induced sway and showed a slowing in voluntary, as opposed to reflexive mechanisms of correcting postural disturbance. For both age groups, reflexive mechanisms were found to be relatively intact. When small perturbations were given, the elderly persons swayed more than young participants and produced sporadic reflexive activity. Moreover, elderly persons did not adapt to the small perturbations and exhibited increased postural sway to repetitive presentation of the perturbation, whereas young participants substantially decreased their postural sway. These data demonstrate that elderly persons are at some disadvantage when posture is under the control of slower, higher level sensory integrative mechanisms.

There are known links between the hypothalamic–pituitary–adrenal (HPA) axis and systems responsible for regulating posture. Our aim was to explore directly, for the first time, whether an aspect of circadian HPA axis activity (the cortisol awakening response: CAR) was associated with greater visual dependency in postural control. For measurement of the CAR, electronically monitored saliva samples were collected by participants following morning awakening in their home environment. On the afternoons of the same days, postural sway was measured in the laboratory by exposing participants to static (control) and moving visual stimuli whilst standing still and upright on a force platform. Visual dependence was assessed as the increase in postural sway (path length) during exposure to the moving compared with the static condition. The 44 measurement days were derived from four days for each of eleven healthy participants (mean ± SD age: 51.18 ± 3.3 years). As expected, postural sway was greater when exposed to moving versus static cues. Mixed regression modelling showed that participants with smaller four day average CARs had greater deterioration in postural sway when presented with moving stimuli. These data are the first to document associations between the CAR and visual dependency in postural sway.

Background: Stroke is one of the most debilitating diseases among the adults around the world which leads to persistent rehabilitation needs even at chronic stage. Achievement of good postural control is a critical requirement for daily activities which enhances quality of life in patients with stroke. There is increasing evidence that transcranial direct current stimulation (tDCS) may be considered as a promising adjunct technique to improve motor recovery after stroke. Evidence of augmented neuroplasticity after tDCS suggests that a paired rehabilitation followed by consecutive use of tDCS may optimize recovery outcomes. Although a few RCTs have been conducted on upper limbs rehabilitation in chronic stroke using tDCS, however no study focused on balance training in chronic stroke patients. This randomized, sham-controlled, double-blinded clinical study aims to address brain stimulation targeting postural control using tDCS in chronic stroke. Methods: The study participants will be chronic ischemic stroke individuals with postural control impairments who meet no exclusion criteria. Active or sham anodal tDCS will delivered to lesioned leg motor cortex combined with balance training. Experimental group receive active anodal tDCS stimulation (2mA) for 20 min, daily for 5 days paired with balance training. Linear and nonlinear approaches will be used to analyse postural sway changes pre and post-intervention. Postural sway fluctuation, Functional balance assessment using Berg balance scale, Timed Up-and-Go Test will be compared in active and sham groups. Conclusions: This trial could have significant implications for balance rehabilitation after stroke in the ambulatory setting. If found to be effective, this novel approach may improve rehabilitation protocol in this population.

Postural sway has been demonstrated to increase following exposure to different types of motion. However, limited prior studies have investigated the relationship between exposure to normative on-road driving conditions and standing balance following the exposure. The purpose of this on-road study was to quantify the effect of vehicle motion and task performance on passengers’ post-drive standing balance performance. In this study, trunk-based kinematic data were captured while participants performed a series of balance exercises before and after an on-road driving session in real-time traffic. Postural sway for all balance exercises increased following the driving session. Performing a series of ecologically relevant visual-based tasks led to increases in most post-drive balance metrics such as sway position and velocity. However, the post-drive changes following the driving session with a task were not significantly different compared to changes observed following the driving session without a task. The post-drive standing balance performance changes observed in this study may increase vulnerable users’ risk of falling. Wearable sensors offer an opportunity to monitor postural sway following in-vehicle exposures.

AbstractWe present detailed experimental results with cryogenic Yb:YLF gain media in rod-geometry. We have comparatively investigated continuous-wave (cw) lasing and regenerative amplification performance under different experimental conditions. In the cw lasing experiments effect of crystal doping, cw laser cavity geometry and pump wavelength on lasing performance were explored. Regenerative amplification behavior was analyzed and the role of depolarization losses on performance was investigated. A recently developed temperature estimation method was also employed for the first time in estimating average crystal temperature under lasing conditions. It is shown that the thermal lens induced by transverse temperature gradients is the main limiting factor and strategies for future improvements are discussed. To the best of our knowledge, the achieved results in this study (375 W in cw, and 90 W in regenerative amplification) are the highest average powers ever obtained from this system via employing the broadband E//a axis.
