Background The effects of shoes and foot type on balance are unclear. We aimed to investigate the differences between static and dynamic balance among three foot types and the changes in postural balance while wearing typical athletic shoes. Methods Based on the Foot Posture Index, the feet of 39 participants were classified as pronated, neutral, or supinated by a physiatrist. Static and dynamic balance function were assessed by center of gravity (COG) sway velocity with eyes open and eyes closed and a modified Star Excursion Balance Test in a random order with participants either barefoot or wearing shoes. Results The COG sway velocity was significantly higher in the supinated foot group than in the neutral foot group (barefoot: eyes open, P = .004, eyes closed, P = .001). Normalized composite reach distance (NCRD) was significantly lower in the pronated and supinated foot groups (barefoot: P = .039, P = .008; shoes: P = .018, P = .018). In all three foot type groups, COG sway velocity was significantly decreased (P < .05) and NCRD was significantly increased (P < .05) while wearing typical athletic shoes. Conclusions The medial longitudinal arch of the foot affects postural balance. Typical athletic shoes improve postural balance regardless of foot type. However, the pronated and supinated foot groups still had lower dynamic postural balance compared with the neutral foot group, even when wearing athletic shoes. People with pronated and supinated feet may need additional interventions, such as foot orthoses or balance training.

Background. Core stability (or core strengthening) has become a well-known fitness trend that has started transcending into sports medicine. It has become a common practice to incorporate balance tasks into the training program for athletes who want to improve performance and prevent injuries. Hypothesis. We suggest that core stabilization and balance training with closed eyes will be more effective than training with open eyes. The aim of the study was to evaluate the effect of core stabilization training with open eyes versus closed eyes on balance and stability of young football players. Methods. Fourteen healthy young football players aged 10–12 years were assessed for pre and post core stabilization training using two balance tests: Stork Balance Test (SBT) and Modified Star Excursion Balance Test (mSEBT), and one test for core stability ‒ McGill Core Stability Test (MCST). The intervention included twelve twenty-minute training sessions each of them involved six core strengthening exercises. One group performed exercises with open eyes, and another with eyes closed. Results. Core stability exercises with eyes closed as well as the same exercise done with eyes open insignificantly improved dynamic balance and core stability, but significantly improved the static balance of the subjects. Conclusion. After applying training with closed eyes as well as eyes open, core stability and balance of young football players increased insignificantly. There were no significant differences in core stability and balance training between training with eyes open and eyes closed.Keywords: core stabilization training, balance, open eyes, closed eyes.

Abstract BackgroundPostural instability is one of the most disabling features of spinocerebellar ataxias type 3 (SCA3) and often leads to falls that reduce mobility and functional capacity. This study aimed to quantitatively analyse static and dynamic balance and proprioception function on postural control in patients with SCA3 using the Pro-kin system and optimise rehabilitation programmes for them.MethodsEight-one clinically diagnosed SCA3 patients (38 women, 43 men; aged 39.00 ± 9.66) and 62 healthy controls were studied and evaluated using the Pro-kin system (PK254P, Tecnobody S.r.l, Dalmine, Italy). The measurements included (1) a static balance test in two visual feedback conditions: eyes open (EO) and eyes closed (EC); (2) a dynamic balance test measuring limits of stability (LOS); and (3) a proprioception function test to obtain proprioceptive measurements on a multiaxial balance evaluator for both right and left lower limbs.ResultsCompared to controls, SCA3 patients showed significantly higher values of all static balance outcome variables with eyes open and eyes closed, implying postural instability. SCA3 patients showed significantly higher values in the standard deviation of body sway along the medio-lateral (ML) axis and in the velocity of body sway along the anterior-posterior (AP) axis. The overall scores and the scores for all eight LOS components were significantly lower in the SCA3 patients than in the controls. The mean values of AP index (API), ML index (MLI), Stability index (SI) and average trace error (ATE) were significantly greater in SCA3 patients compared to HC subjects, while API showed a trend toward higher values.ConclusionsSCA3 patients have a significant postural control disorder, and are likely to fall on the AP plane and prefer performing postural adjustments in the ML direction; a decreased proprioception function in the knee and ankle is also evident. Visual cues and proprioception should be emphasized in balance rehabilitation training. Attention should also be paid to improve muscle strength and range of motion.Trial registrationThe Chinese clinical test registration center. ChiCTR1800020133.

Alpine Skiers

This experiment examined changes in body sway after Wingate test (WAnT) in 19 adolescents practicing alpine skiing, subjected to the same type of training load for 4–5 years (10 girls and nine boys). The postural examinations were performed with eyes open (EO), eyes closed (EC), and sway reverenced vision (SRV) in the medial-lateral (ML) and anterior-posterior (AP) planes. The displacement of center of foot pressure (CoP), range of sway (RS), mean sway velocity (MV), way length, and surface area were measured in bipedal upright stance before and after the WAnT to assess the influence of fatigue on postural balance. There were no significant differences in WAnT parameters between girls and boys. Relative peak power (RPP), relative total work (RWtot) were (girls vs. boys) 8.89 ± 0.70 vs. 9.57 ± 1.22 W/kg, p < 0.05 and 227.91 ± 14.98 vs. 243.22 ± 30.24 W/kg, p < 0.05 respectively. The fatigue index (FI) was also on similar level in both genders; however, blood lactate concentration (BLa) was significantly higher in boys (10.35 ± 1.16 mM) than in girls (8.67 ± 1.35 mM) p = 0.007. In the EO examination, statistically significant differences between resting and fatigue conditions in the whole group and after the division into girls and boys were found. In fatigue conditions, significant gender differences were noted for measurements in the ML plane (sway path and RS) and RS in the AP plane. Comparison of the three conditions shows differences between EO vs. EC and SRV in AP plane measured parameters, and for RS in ML plane in rest condition in girls. The strong correlations between FI and CoP parameters mainly in ML plane in the whole group for all examination conditions were noted. By genders, mainly RS in ML plane strongly correlates with FI (r > 0.7). No correlation was found between BLa and CoP parameters (p > 0.06). The presented results indicate that subjecting adolescents of both genders to the same training may reduce gender differences in the postural balance ability at rest but not in fatigue conditions and that girls are significantly superior in postural balance in the ML plane than boys. It was also shown that too little or too much information may be destructive to postural balance in young adolescents.

Balance disorders have a high prevalence among elderly people in developed countries, and falls resulting from balance disorders involve high healthcare costs. Therefore, tools and indicators are necessary to assess the response to treatments. Therefore, the aim of this study is to detect relevant changes through minimal detectable change (MDC) values in patients with balance disorders, specifically with vertigo. A test-retest of a static and dynamic balance test was conducted on 34 healthy young volunteer subjects using a portable stabilometric platform. Afterwards, in order to show the MDC applicability, eight patients diagnosed with balance disorders characterized by vertigo of vestibular origin performed the balance test before and after a treatment, contrasting the results with the assessment by a specialist physician. The balance test consisted of four tasks from the Romberg test for static balance control, assessing dynamic postural balance through the limits of stability (LOS). The results obtained in the test-retest show the reproducibility of the system as being similar to or better than those found in the literature. Regarding the static balance variables with the lowest MDC value, we highlight the average velocity of the center of pressure (COP) in all tasks and the root mean square (RMS), the area, and the mediolateral displacement in soft surface, with eyes closed. In LOS, all COP limits and the average speed of the COP and RMS were highlighted. Of the eight patients assessed, an agreement between the specialist physician and the balance test results exists in six of them, and for two of the patients, the specialist physician reported no progression, whereas the balance test showed worsening. Patients showed changes that exceeded the MDC values, and these changes were correlated with the results reported by the specialist physician. We conclude that (at least for these eight patients) certain variables were sufficiently sensitive to detect changes linked to balance progression. This is intended to improve decision making and individualized patient monitoring.

Posture Stability

The effects of different factors—such as age, sex, performance level, and athletic shoe features—on postural balance in athletes remain unclear. The main objective of our study is to identify the features of postural stability in athletes of different age, sex, performance level, and using different types of athletic shoes. This study assessed postural stability in athletes (n = 936, 6–47 years) in a normal bipedal stance with eyes open (EO) and eyes closed (EC). Postural stability was evaluated based on the center of pressure (COP), sway area (AS), and velocity (VCP) while standing on a stabiloplatform. Children (6–12 years) and teen athletes (13–17 years) showed reduced AS-EO (p < 0.01) and VCP-EO (p < 0.01) compared to control (n = 225, 7–30 years). In male and female athletes aged 18+, only VCP-EC was lower versus control. In females (13–17 and 18+), VCP-EO and EC were lower than in males (p < 0.05). Only in the Shooting group, the athletes’ performance levels had an effect on VCP-EO (p = 0.020). Long use of rigid athletic shoes with stiff ankle support was associated with reduced posture stability. Postural stability in athletes was mostly influenced by the athlete‘s age, and, to a lesser extent, by their sex, performance level, and athlete shoe features.

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 &lt; 0.001) and anteroposterior amplitude (p &lt; 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.

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.

AbstractPurposeThe objective of this pilot study was to compare the effects of two parallel balance trainings on postural sway and balance confidence. The study was performed in different contexts with stable vs. unstable base of support and balance confidence was measured with a scale modified for young adults with higher functional level.Materials/methodsTwenty healthy female physiotherapist students volunteered for the study and took part in a six-week balance training intervention. They were randomly assigned to two groups training on different support surfaces. Postural sway was recorded under various conditions: on different surfaces (firm, foam) and with different visual conditions (eyes open (EO), eyes closed (EC)). Modified Activities-specific Balance Confidence (mABC) scale was self-evaluated.ResultsBoth types of training caused a significant improvement in the mABC scores. The sway path increased after the training in the less challenging balance situations. We found a tendency of decreasing sway path only in the more challenging balance situations, that is standing on foam mounted on force plate with EC.ConclusionsConsidering the improved balance confidence in the case of both groups, we suggest that an increase in sway path after balance training may be the behavioural sign of the higher confidence in the less challenging balance situations.

Abstract Alterations in balance and gait are frequently present in patients with hemiparesis. This study aimed at determining whether there is a correlation between static and functional balance, gait speed and walking capacity. To that end, 17 individuals with chronic hemiparesis of both sexes (58.8% men and 42.25 women), mean age of 56.3 ± 9.73 years, took part in the study. Static balance was assessed by computerized baropodometry, under two different sensory conditions: eyes open (EO) and eyes closed (EC). Functional balance was evaluated by Berg Balance Scale and walking ability by the Functional Ambulation Classification. Gait speed was assessed by kinemetry. The Kolmogorov-Smirnov test was used to verify data distribution normality. Parametric variables were correlated by Pearson's test and their non-parametric parameters by Spearman's test. Functional balance showed a positive correlation with gait speed (p=0.005; r=0.64) and walking ability (p = 0.019; r = 0.56). Anteroposterior (AP) and mediolateral (ML) alterations with EO and EC exhibited negative correlations with gait speed (EO: AP amplitude (p = 0.0049 and r = -0.48); mean ML deviation (p = 0.019 and r =-0.56)/ EC: mean AP deviation (p = 0.018 and r = -0.56) and mean ML deviation (p = 0.032 and r = -0.52); AP amplitude (p = 0.014 and r = -0.57) and ML amplitude (p = 0.032 and r = -0.52); postural instability (p = 0.019 and r = -0.55)) and walking ability (EO: mean AP deviation (p = 0.05 and r = -0.47) and AP amplitude (p = 0.024 and r = -0.54)). The results suggest correlations between static and functional balance and gait speed and walking ability, and that balance training can be an important component of gait recovery protocols.

Tendon Properties

A 63-year-old male was diagnosed with multiple sclerosis (MS) two years prior to this investigation. We hypothesized that compromised postural balance in MS can be improved by training-induced alterations in muscle-tendon properties. Sixteen weeks of strength and balance training induced an increase in quadriceps and gastrocnemius muscle size, strength, central activation, muscle recruitment and tendon stiffness. Concomitantly, the ability to maintain postural stances was increased in both eyes-open and eyes-closed conditions. We concluded that improvements in muscle-tendon properties were accompanied by improved balance and a general feeling of well-being after training.
