Background: ‪Because of the proximity of anatomical structures involved in auditory and vestibular functions, complications concerning the inner ear may lead to problems involving both systems. This study investigated whether static balance and knee proprioception in deaf basketball players are different from those in individuals with normal hearing. Material and methods: ‪12 deaf national basketball players and 13 individuals with normal hearing were included. Static balance was evaluated using the Biodex-BioSway Balance System. Knee proprioception was assessed using a Dualer IQ Digital Inclinometer with the active angle repetition test. Results: ‪The dominant-side mediolateral stability index and non-dominant-side overall, anteroposterior, and mediolateral stability index scores of deaf basketball players in the postural stability test were different compared with those of the individuals with normal hearing (p<0.05). There was no statistically significant difference between the two groups in terms of knee proprioception (p>0.05). Conclusions: ‪Although there was no difference in knee proprioception in deaf basketball players, it is noteworthy that their postural stability was more impaired compared with that in individuals with normal hearing. Despite regular exercise, deaf basketball players had poorer balance than individuals with normal hearing. Therefore, balance and vestibular exercises should be added to the training programs of these athletes.

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.

Abstract Background Only limited data are available regarding postural stability between anterior cruciate ligament (ACL)-injured patients with medial meniscus (MM) tear and those with lateral meniscus (LM) tear. The purpose of this study was to compare preoperative postural stability for both involved and uninvolved knees in ACL rupture combined with MM and LM tears. It was hypothesized that there would be a significant difference in postural stability between these two groups. Methods Ninety-three ACL-injured patients (53 combined with MM tears vs. 40 combined with LM tears) were included. Static and dynamic postural stability were evaluated with the overall stability index (OSI), anterior–posterior stability index (APSI), and medial–lateral stability index (MLSI) using stabilometry. Knee muscle strength was evaluated using an isokinetic testing device. Results In the static postural stability test, none of the stability indices showed significant differences between the two groups for both knees (p > 0.05). In the dynamic postural stability test for involved side knees, the OSI and APSI were significantly higher in the LM tear group compared to the MM tear group (OSI: 2.0 ± 0.8 vs. 1.6 ± 0.5, p = 0.001; APSI: 1.5 ± 0.6 vs. 1.3 ± 0.5, p = 0.023), but not the MLSI (p > 0.05). In the static and dynamic postural stability tests in each group, there were no significant differences between the involved and uninvolved side knees (p > 0.05). There was no significant difference in the knee muscle strength between the two groups (p > 0.05). All postural stability showed no significant correlation with knee muscle strength (p > 0.05). Conclusion Dynamic postural stability was poorer in patients with ACL rupture combined with LM tear than in those with MM tear. Therefore, close monitoring for postural stability would be necessary during preoperative and postoperative rehabilitation, especially for patients with ACL rupture combined with LM tear. Level of evidence: Level III

Stability plays a key role in the sport competition in football. Synchronized operation stabilization of the lower limb and trunk of the support with the dynamic movement of the contralateral limbs allow you to perform tasks specific to the discipline, eg. variety kicking of the ball. Purpose. The aim of the study was to evaluate differences in the capabilities to maintain postural stability in standing on one leg dominant and non-dominant leg with professional players including grouping variables: age, height, weight, volume of training aimed at improving the stability and general internship of football player career. Although commonly assumed that the non-dominant leg is predisposed to act more effective support for the body, the work to date have failed to identify indicated differentiation. It should be noted, however, that they were carried out on small trials in people less active, or among amateur athletes. Basic procedures. The study involved 31 professional soccer players from 1 to 5 level of division. In order to assess postural stability, each of the test performed three times a standard stability test consisting of three 20-second attempt to maintain balance on one leg becoming dominant and non-dominant leg on stabilometric platform BIODEX Balance System. For each of the lower limbs test was repeated three times. Assessment were average angular range deflections platform in the two reference planes, and the volatility of these deflections. These parameters were treated as a measure of postural stability of the respondents. Main findings. In the whole group of patients, no statistically significant differences in the possibilities to maintain postural stability in standing on one leg dominant and non-dominant leg. No significant differences were also detected when considering grouping variables. Conclusions. The results do not indicate a significant difference in the ability to maintain postural stability in standing on one leg dominant and non-dominant leg in professional soccer players.

Posture is the most healthy and correct placement of each region in the body when compared to the whole body. The predominantly use of one side of the body disrupts the posture. A bad posture changes the center of gravity of the body and causes chronic skeletal and muscle soreness. It is aimed to determine whether there is a rehabilitative effect of football training that does not require the use of dominant arms on posture asymmetries which may occur in the basketball which requires the use of dominant arm and leg in the study.15 male basketball players who played basketball for an average of 8 years with a mean age of 21.7 ± 1.5 years participated as volunteers. Postures of the subjects were measured with PostureScreen Mobile® before and after 12 week football trainings with lateral and anteriorly taken photographs. SPSS 22 was used program for statistical analysis. While analyzing of data Wilcoxon Test method was used and it is determined as significance level was p<0.05.After 12 weeks of football training, statistically significant differences were found in measurements taken from the anterior and lateral positions on the head, shoulder, ribcage, hip, and knee measured tilts and shifts. Estimated average head weight decreased depending on the posture of the cervical vertebrae and a significant difference was detected. Postures of subjects came close to the correct posture.Basketball is an acycle sport branch that requires the use of muscles on the dominant side. It creates an asymmetric position on the athlete due to this feature; causes shifting and tilts. In order to eliminate postural disorders that occur, the effectiveness of football training that does not require to use of the dominant side of the body has been demonstrated.

In sports such as basketball and volleyball, loss of balance due to the inability to maintain body stability and lack of postural control adversely affect athletic performance. Deaf athletes appear to struggle with balance and postural stability problems. The purpose of this study was to examine postural sway values in parallel and single leg stance of Olympic deaf basketball and volleyball players and reveal differences between the branches. Twenty-three male athletes from the Turkish national deaf basketball (n= 11) and volleyball (n= 12) teams participated in the study. After anthropometric measurements, the subjects completed postural sway (PS) tests in parallel/single leg stances with open eyes and closed eyes on a force plate. PS parameters (sway path, velocity, and area) obtained from the device software were used for the statistical analysis. The Mann-Whitney U-test was used to compare differences in PS parameters between basketball and volleyball players, and the alpha value was accepted as 0.05. Volleyball players had significantly better results in parallel stance and dominant leg PS values than basketball players (P<0.05). There was no significant difference between the groups in nondominant leg PS values (P>0.05). We think that proprioceptive and vestibular system enhancing training practices to be performed with stability exercises will be beneficial in terms of both promoting functional stability and interlimb coordination. Trainers and strength coaches should be aware of differences in the postural control mechanism of deaf athletes.

Abstract Background The coach attitude impacts the whole mind and body system of a child athlete from emotional and motivational aspects to motor skills like motor coordination. It translates into the ability to control and stabilize posture. The vestibular system plays an important role in this regulation. This system, next to the visual system and mechanoreceptors, is responsible for balance and control during posture transition. Moreover, the vestibular system is influenced by emotional factors. Therefore the authors of this study focused on the changes in the balance stability of children practicing sport after the implementation of the psychological workshops for coaches. Methods Fifty-nine children at the age of 9–12 practicing soccer, art gymnastic and sport gymnastic were divided into two groups. The experimental group consisted of 31 participants and 28 in the control group. Experimental group children were under the influence of the 3 coaches who attended three workshops over 12 weeks period. Control group children were coached by 5 coaches who attended no workshops. Postural stability tests were performed on children before and after the workshops. Results The statistically significant changes were observed in selected parameters of children’s balance stability after the experiment. The significant difference between the experimental and control group in Overall Stability Index (OSI) (p < 0.0002), Anterior–Posterior Stability Index (AP) (p < 0.01), Medial–Lateral Stability Index (ML) (p < 0.01) with eyes open were observed after the experiment. The results show a significant deterioration in control group contrary to the experimental group where the improvement trend was observed. Moreover, the difference between the groups was observed in OSI parameter (p < 0.005) with eyes closed after the experiment. Conclusion The results obtained by the authors of the current study may support the thesis that educating coaches allows for better results in postural stability of child’s athletes. Nevertheless, this thesis requires further research, with particular emphasis on the age and gender of young athletes.

The objective of this study was to evaluate the relationship between the anthropometric factors of height, body mass, body mass index and postural balance and to compare the balance indices between genders in the upright standing position, in healthy adult subjects under conditions of instability. Forty individuals were subjected to functional tests of body stability using the Biodex Balance System, and the resulting indices were correlated with body mass, height, and body mass index, and also compared between genders. Body mass was the main anthropometric factor that influenced variations in postural balance, with a high correlation between groups and with all variables. A linear regression analysis showed that body mass associated with BMI explained 66% of the overall stability, and body mass explained 59% of the anteroposterior stability index and 65% of the mediolateral stability index. In the female group, body mass explained 72% of the overall balance, 66% of the anteroposterior, and 76% of the medio-lateral stability index. Increased body mass requires greater movements to maintain postural balance. Height and BMI presented moderate correlations with balance. Women showed less movement than men on the Biodex Balance System.

Objective: This study aimed to investigate the static and dynamic balance in basketball students with an ankle injury history. Methods: Subjects of this study were 36 elementary school basketball male students who participated in this study purposefully and voluntarily. Subjects were divided into two groups of 18 people with an ankle injury and the control group without ankle injury. To measure the static balance from the stork test and the dynamic balance from the star test was used. Descriptive statistics (mean and standard deviation) and inferential statistics (Shapiro-Wilk test and independent t-test) were used to analyze the results. Results: There was a significant difference between the static balance of basketball students and the control group (P=0.001), but no significant difference was found between basketball studentschr('39') dynamic balance with ankle injuries and the control group (P=0.0887). Conclusion: Based on research results, it can be concluded that lower limb injuries, especially ankle injuries they can influence postural control and static balance of basketball students and caused some functional disability. Also recommended coaches during the sports era of basketball players to design specific exercises to strengthen ankle muscles and ligaments and use static balance exercises not to witness this type of injury.

This study aimed to investigate the effects of varying midsole hardness on center of pressure (COP) and perceived stability during basketball-specific tasks, as well as the correlation between COP and perception measurements. A total of 20 male basketball players performed 45° cutting and layup while wearing basketball shoes with soft and hard midsoles. COP trajectories were obtained from the Pedar insole system. Stability perceptions at the forefoot and rearfoot were assessed using 150-mm visual analogue scales. Results indicated greater COP mediolateral deviations in soft midsole compared with hard midsole during layup (soft: 16.6 [4.7] mm, hard: 15.8 [4.6] mm, P = .03) but not 45° cutting (soft: 15.7 [5.9] mm, hard: 15.8 [5.6] mm, P = .60). While 16 out of 20 participants preferred soft midsole, no significant difference in visual analogue scale ratings was found between shoes for both tested movements. There was no significant correlation between COP and perceived stability during layup or 45° cutting. In conclusion, midsole hardness of basketball shoes did not consistently affect mediolateral stability of the foot during 45° cutting and layup. Subjective perception alone cannot be used to indicate mediolateral deviation of the foot when executing basketball-specific maneuvers.
