ABSTRACT Background: Migraine is one of the most frequent and incapacitating headaches, with a high degree of impairment of balance control and postural stability. Objective: To investigate the effects of episodic and chronic migraine on postural balance through using static and dynamic balance tests. Methods: The study included 32 chronic and 36 episodic migraine patients and a control group of 36 healthy volunteers. Right/left single-leg static and dynamic balance tests were performed in each group with eyes open and closed using a posturographic balance platform (Techno-body Prokin). Results: No significant difference was found among episodic and chronic migraine patients and control subjects with regard to eyes-open and eyes-closed area values (eyes-open area values: p=0.559, p=0.414 and p=0.906; eyes-closed area values: p=0.740, p=0.241 and p=0.093, respectively). However, the area values were significantly higher in episodic and chronic migraine patients than in the control group, which indicates that migraine patients may have lower balance performance. Perimeter values were relatively higher which supports the idea that migraine patients have lower balance performance. Additionally, the average number of laps was significantly lower among migraine patients than in the control group, which also implies that migraine patients may have lower balance performance. Conclusion: Although no significant difference was detected between chronic and episodic migraine patients and the control group and between chronic and episodic migraine patients with regard to balance performance, chronic migraine patients seemed to have relatively lower performance than episodic migraine patients. Further studies with larger numbers of patients are needed, to investigate the relationship between these parameters and balance.

The aim of this research was to investigate the effect of vibration applications on muscle strength and balance. As the subjects to the research, nineteen male sport science students (age: 21.45±2.16 years, height: 177.55±7.24 cm, body mass: 71.62±11.02 kg) voluntarily participated in the study. The students were exposed to vibration in squat exercise position before they were exposed to vibration at 25Hz, 50Hz frequency and control (no-vibration) on three different application days. Before and after the vibration exposure, jump tests and balance tests were administered right after the 5th, 10th and 15th min in the wake of the vibration. A statistically significant difference was found in active and squat jump heights administered following the 25Hz and 50 Hz frequency applications (p≤0.05). No significant differences were found in the jump heights in control group (p>0.05). While there was no significant difference found in balance tests performed after 25Hz and 50Hz vibration applications (p>0.05), a significant difference was found after the control application (p≤0.05). As a result, there was an increase in jump heights following the acute vibration application however, no change was seen in balance scores. Practicing acute vibration applications can be recommended to increase jump height especially before the competitions and applications.

Dance has been suggested to be an advantageous exercise modality for improving postural balance performance and reducing the risk of falls in the older population. The main purpose of this study was to investigate whether visual restriction impacts older dancers and non-dancers differently during a quiet stance balance performance test. We hypothesized higher balance performance and greater balance deterioration due to visual restriction in dancers compared with non-dancers, indicating the superior contribution of the visual channel in the expected higher balance performances of dancers. Sixty-nine (38 men, 31 women, 74 ± 6 years) healthy older adults participated and were grouped into a Greek traditional dance group (n = 31, two to three times/week for 1.5 h/session, minimum of 3 years) and a non-dancer control group (n = 38, no systematic exercise history). The participants completed an assessment of one-legged quiet stance trials using both left and right legs and with eyes open while standing barefoot on a force plate (Wii, A/D converter, 1,000 Hz; Biovision) and two-legged trials with both eyes open and closed. The possible differences in the anthropometric and one-legged balance parameters were examined by a univariate ANOVA with group and sex as fixed factors. This ANOVA was performed using the same fixed factors and vision as the repeated measures factor for the two-legged balance parameters. In the one-legged task, the dance group showed significantly lower values in anteroposterior and mediolateral sway amplitudes (p = 0.001 and p = 0.035) and path length measured in both directions (p = 0.001) compared with the non-dancers. In the two-legged stance, we found a significant vision effect on path length (p < 0.001) and anteroposterior amplitude (p < 0.001), whereas mediolateral amplitude did not differ significantly (p = 0.439) between closed and open eyes. The dance group had a significantly lower CoP path length (p = 0.006) and anteroposterior (p = 0.001) and mediolateral sway amplitudes (p = 0.003) both in the eyes-open and eyes-closed trials compared with the control group. The superior balance performance in the two postural tasks found in the dancers is possibly the result of the coordinated, aesthetically oriented intersegmental movements, including alternations between one- and two-legged stance phases, that comes with dance. Visual restriction resulted in a similar deterioration of balance performance in both groups, thus suggesting that the contribution of the visual channel alone cannot explain the superior balance performance of dancers.

Visual Conditions

Background Studies demonstrated that the older adults can be more susceptible to balance instability after acute visual manipulation. There are different manipulation approaches used to investigate the importance of visual inputs on balance, e.g., eyes closed and blackout glasses. However, there is evidence that eyes open versus eyes closed results in a different organization of human brain functional networks. It is, however, unclear how different visual manipulations affect balance, and whether such effects differ between young and elderly persons. Therefore, this study aimed to determine whether different visual manipulation approaches affect quasi-static and dynamic balance responses differently, and to investigate whether balance responses of young and older adults are affected differently by these various visual conditions. Methods Thirty-six healthy participants (20 young and 16 older adults) performed balance tests (quasi-static and unexpected perturbations) under four visual conditions: Eyes Open, Eyes Closed, Blackout Glasses, and Dark Room. Center of pressure (CoP) and muscle activation (EMG) were quantified. Results As expected, visual deprivation resulted in larger CoP excursions and higher muscle activations during balance tests for all participants. Surprisingly, the visual manipulation approach did not influence balance control in either group. Furthermore, quasi-static and dynamic balance control did not differ between young or older adults. The visual system plays an important role in balance control, however, similarly for both young and older adults. Different visual deprivation approaches did not influence balance results, meaning our results are comparable between participants of different ages. Further studies should investigate whether a critical illumination level may elicit different postural responses between young and older adults.

Techniques to quantify postural stability usually rely on the evaluation of only two variables, that is, two coordinates of COP. However, by using three variables, that is, three components of acceleration vector, it is possible to describe human movement more precisely. For this purpose, a single three-axis accelerometer was used, making it possible to evaluate 3D movement by use of a novel method, convex polyhedron (CP), together with a traditional method, based on area of the confidence ellipse (ACE). Ten patients (Pts) with cerebellar ataxia and eleven healthy individuals of control group (CG) participated in the study. The results show a significant increase of volume of the CP (CPV) in Pts or CG standing on foam surface with eyes open (EO) and eyes closed (EC) after the EC phase. Significant difference between Pts and CG was found in all cases as well. Correlation coefficient indicates strong correlation between the CPV and ACE in most cases of patient examinations, thus confirming the possibility of quantification of postural instability by the introduced method of CPV.

This cross-sectional exploratory study aimed to compare the one-leg-stance time and the six-minute walk distance among TC Qigong-trained NPC survivors, untrained NPC survivors, and healthy individuals. Twenty-five survivors of NPC with TC Qigong experience, 27 survivors of NPC without TC Qigong experience, and 68 healthy individuals formed the NPC-TC Qigong group, NPC-control group, and healthy-control group, respectively. The one-leg-stance (OLS) timed test was conducted to assess the single-leg standing balance performance of the participants in four conditions: (1) standing on a stable surface with eyes open, (2) standing on a compliant surface with eyes open, (3) standing on a stable surface with eyes closed, and (4) standing on a compliant surface with eyes closed. The six-minute walk test (6MWT) was used to determine the functional balance performance of the participants. Results showed that the NPC-control group had a shorter OLS time in all of the visual and supporting surface conditions than the healthy control group(P<0.05). The OLS time of the TC Qigong-NPC group was comparable to that of the healthy control group in the somatosensory-challenging condition (condition 3)(P=0.168)only. Additionally, there was no significant difference in the 6MWT distance among the three groups(P>0.05). TC Qigong may be a rehabilitation exercise that improves somatosensory function and OLS balance performance among survivors of NPC.

Background and Study Aim: In order to sustain the performance in sport, it is necessary to constantly struggle with the factors which disrupt balance, and maintain the desired balance. The purpose of the present study is to compare and demonstrate the effects of sight grade on static and dynamic balance, and fall risk parameters in visually impaired and non-impaired judo athletes and goalball/futsal players. Material and Methods: A total of 26 male athletes (13 Judo, 13 Goalball/Futsal) participated in the study voluntarily. The participants performed two balance tests as Overall Stability Test and Fall Risk Test with the eyes open and eyes closed. The parameters observed were static and dynamic overall stability, anterior-posterior, and medial-lateral index, and fall risk. Results: According to the findings, there were significant differences in all the parameters with the eyes open and eyes closed conditions in visually non-impaired athletes regardless of the sport branch, while visually impaired athletes showed no significant difference. However, more loss of balance was observed in all the parameters for visually impaired athletes. Conclusions: These findings show that visual system has a crucial role on balance, and athletes with visually impaired have more advanced vestibular system and proprioceptive senses to maintain their balance. It was also understood that visually non-impaired athletes tend to show more deteriorated balance level when their eyes were closed. Future studies could examine the vestibular and proprioceptive senses besides visual system to provide information about how balance is affected from other systems.

The Stability

Proper posture provides the best balance and body stability at minimal muscular effort. It is constantly controlled by the central nervous system, which integrates the stimuli from the proprioceptors (deep feeling sensors), vision receptors, and balance receptors through the subcortical structures. The main purpose of the study was to describe single stance stability and its correlation with the degree of scoliosis and trunk rotation among patients suffering from idiopathic scoliosis and in the control group without scoliosis. The study included 80 patients (69 girls and 11 boys) and 40 healthy children without scoliosis (21 girls and 19 boys). The Cobb angle technique was used to determine the magnitude of the deformity. All subjects were divided into three subgroups according to Bogdanov’s classification. Single stance stability with eyes open and eyes closed was assessed with an electronic postural station—Delos Postural Proprioceptive System (DPPS). In case of multiple group comparisons for variables with normal distribution ANOVA with Scheffe, post hoc test was used or Kruskal-Wallis test was used as the nonparametric equivalent. The relationship between the two continuous variables was investigated using either Pearson product-moment correlation or Spearman’s rank correlation. In all these calculations, the statistical significance level was set to p<0.05. The single stance test showed a significant difference between the stability index with eyes open and stability index with eyes closed in study and control groups. The character of these alterations is influenced by the degree of trunk rotation. The degree of scoliosis according to Bogdanov classification does not determine the decrease in stability indexes. In summary, significantly lower values of the stability index during one-leg standing with eyes closed indicated balance impairment, which is mainly connected with inadequate functioning of the proprioceptive system.

Category: Ankle Introduction/Purpose: Chronic ankle instability (CAI) is a disease entity commonly seen after ankle ligament injury. It is divided into mechanical ankle instability (MAI) and functional ankle instability (FAI), with different pathological conditions. The purpose of this study was to test the balancing ability of MAI and FAI patients. Methods: 30 CAI patients and 10 normal subjects were included according to the injury history, clinical symptom and MRI presentation. Stress tests were given under fluoroscopy to find out those with mechanical instability in CAI patients. Among them there were 18 MAI and 12 FAI patients. All patients were tested on a customized balancing ability assessment system developed by Shanghai Jiaotong University. Subjects were asked to stand on the platform for 30 seconds for both feet, 10 seconds for single foot, with eyes open. And 30 seconds for both feet, 5 seconds for single foot, with eyes closed. Each condition was tested for 3 trials and results were averaged. Parameters of balance like the swaying trajectory length and speed at both medial-lateral and anterior-posterior directions, the trajectory length per unit were obtained. Results were compared among three groups. Results: The MAI group presented significantly greater imbalance in both medial-lateral and anterior-posterior directions compared with that in the control group while standing on the single diseased foot, with eyes open or closed. While in the FAI group, no significant difference was found in postural sway compared with that in the control group. The MAI group presented significantly greater imbalance in both medial-lateral and anterior-posterior directions than the FAI group while standing on the single diseased foot with eyes open or closed. No significant difference in balancing was found of the contralateral ankle in the two groups. Conclusion: The balancing ability of MAI patients was impaired and then make them vulnerable to falling. Thus either balance training program or reconstructive surgery is needed to restore the balancing ability in those patients.

In this study, it was aimed to determine the effects of plyometric exercises applied on unstable platforms on static and dynamic balances of soccer players who continued their high school education. In the study, male soccer players with similar socio-economic status between the ages of 14 and 16 formed the study group (SG; n=24; age=15.08±1.36) and the control group (CG; n=22; age=15.22±1.62). Static Balance Eyes Open (SB-EO), Static Balance Eyes Closed (SB-EC) and Dynamic Balance tests (DB) were applied on the SG and CG as pre- and post-tests for both dominant leg (DL) and non-dominant leg (NDL). SG athletes were subjected to plyometric exercises on unstable surfaces for sixteen sessions that were integrated into the physical education lessons in high school while CG athletes performed only a traditional soccer training program. As a result of the statistical analyses, when the pre-post test scores of the SG were examined, dynamic balance-dominant leg (DB-DL; p=0.03), dynamic balance-non-dominant leg (DB-NDL; p=0.03), static balance eyes open-dominant leg (SB-EO-DL; p=0 01), static balance eyes closed -dominant leg (SB-EC-DL; p=0.03) and static balance eyes closed-non-dominant leg (SB-EC-NDL; p=0.01) measurements were found statistically significant (p<0.05) while the CG had statistical improvements only in SB-EO-DL measurements (p=0.03). When the differences between the two groups were examined, only SB-EC-DL measurements were found statistically significant in favor of the SG (p=0.03). In conclusion, especially the improvement of DL observed in the SG is important for optimum performance considering that it is necessary to use both legs effectively in soccer. Considering the multitude of activities performed on a single leg in soccer, it is thought that the increase in bilateral balance can improve the skills that determine soccer performance in difficult conditions such as dribbling, shooting and passing.

Background Children with hearing impairments have a higher risk for deficits in balance and gross motor skills compared with children who are developing typically. As balance is a fundamental ability for the motor development of children, a valid and reliable assessment to identify weaknesses in balance is crucial. Objective The purpose of this study was to investigate the construct validity of posturography and clinical balance tests in children with hearing impairments and in children who are developing typically. Methods The study involved 53 children with typical development and 23 children with hearing impairments who were between 6 and 12 years of age and without neuromotor or orthopedic disorders. All participants completed 3 posturography tests (modified Clinical Test of Sensory Interaction of Balance [mCTSIB], unilateral stance, and tandem stance) and 4 clinical balance tests (one-leg stance with eyes open and with eyes closed, balance beam walking, and one-leg hopping). Results Three conditions of the mCTSIB, unilateral stance, and 2 clinical balance tests were able to distinguish significantly between the 2 groups. Children with hearing impairments showed more difficulties in balance tasks compared with children who were developing typically when 1 or 2 types of sensory information were eliminated or disturbed. The study showed only low to moderate correlations among the different methods of evaluating balance. Conclusions Clinical balance tests and posturography offer different but complementary information. An assessment protocol for balance consisting of posturography and clinical balance tasks is proposed. Static and dynamic balance abilities could not be differentiated and seem not to be a valid dichotomy.
