Abstract Background Giving way and knee instability are common problems in patients with knee osteoarthritis, disrupting the daily activities and balance of the affected individual. The present study aimed to evaluate the postural control status of women with knee osteoarthritis with and without self-report knee instability (KI). Methods This cross-sectional, single-blind study was conducted on 57 female patients with knee osteoarthritis. The patients were selected based on the inclusion and exclusion criteria and divided into two groups of with KI (n = 26) and without KI (n = 31). Fear of movement was assessed using the Tampa questionnaire, the degree of knee instability was measured based on the Fitzgard scale, the static and dynamic balance of the subjects were evaluated with open and closed eyes using a Biodex balance device, and foot pressure distribution situation was measured using a FDM-S-Zebris device. Results Mean comparison showed a significant difference between the subjects with and without KI in static balance only in anterior–posterior direction with open eyes (p = 0.01) and closed eyes (p = 0.0001). In the dynamic balance test, the subjects in both groups had significant differences in terms of all the indicators of anterior–posterior stability (p = 0.001), medial–lateral stability (p = 0.0001), and overall stability (p = 0.0001) with closed eyes. However, no significant difference was observed with open eyes (p > 0.05). Multiple regression also indicated significant positive correlations between pain intensity and disease duration with the degree of KI (p < 0.05). Conclusions According to the results, there were significant differences between the mean pain scores, static and dynamic balance, and the rate of fall between the women with knee osteoarthritis with and without the KI index. Therefore, patients with knee osteoarthritis, which also has an index of KI, are more susceptible to falls, and proper strategies are required to reduce the level of KI in these patients.

Background and Study Aim. Sepak Takraw (ST) is considered Malaysia's national sport, and the nature of this sport requires players to be sufficiently acrobatic. Therefore, players were expected to jump and regain their balance, challenging their dynamic balance (DB). Nonetheless, range of motion (ROM) is closely related to balance. Hence, this study aimed to compare recreational ST players' ankle ROM and DB differences with and without ankle injuries. Material and Methods. The cross-sectional study in which 30 participants were assigned purposively according to players with an ankle injury (n=15) and without ankle injury (n=15) based on the position statement of the International Ankle Consortium (IAC). One time ankle Range of Motion and Dynamic balance was measured using a universal goniometer and Star Excursion Balance Test (SEBT), respectively, for both groups. Results. Independent T-test was performed to identify the significant differences (p<0.05) of SEBT and ROM between the non-injured leg and injured leg within the injured group to the non-injured group. Ankle eversion and dorsiflexion between the injured and non-injured groups did not show any significant difference with p=0.35 & p=0.53, respectively. As for SEBT, only posteromedial and medial of the injured leg did not show a significant difference p>0.05. All other ankles ROM and the SEBT score demonstrated a statistically significant difference p<0.05. Conclusions. ROM and DB training/rehabilitation should be incorporated to all the injured group ST sports players regardless of which leg is affected to optimize ankle function and the game performance.

Background and Aims This study evaluated dynamic balance, quadriceps, and hamstring strength in individuals with Covid 19 compared with healthy control ones. Methods A total of 30 people were divided into two groups, including healthy people (n=15) and people with Covid-19. Dynamic balance was measured using the star excursion balance test. A dynamometer performed lower limb muscle strength measurements. An independent t-test was used to compare the two groups statistically. The significance level was considered 0.05. Results Quadriceps and hamstring muscle strength were similar in both groups (P>0.05). The results showed that the values of dynamic balance in the lateral (P=0.001), medial (P=0.001), and posterior medial (P=0.001) directions were significantly lower in the group with Covid-19 than that in the healthy group. Conclusion In general, the balance of people with Covid-19 was significantly lower than the healthy group. Decreased balance due to this disease can increase the risk of injury. There was no significant difference in lower limb muscle strength in patients with Covid-19 compared with healthy individuals. Perhaps more research is needed in the future to prove this better.

Introduction: The purpose of this study was to investigate the Range of Motion (ROM) and balance symmetry between dominant and non-dominant arms in classic female wrestlers. Materials and Methods: In this cross-sectional study, 13 members of the Iranian Women’s National Classic Wrestling Team participated voluntarily. The shoulder ROM was measured by a goniometer and dynamic balance was assessed by the Y-balance test. Data analysis was done by running a paired t-test, with a 0.95 confidence level (α<0.05). Results: There was no significant difference between dominant and non-dominant upper extremities in flexion (P=0.162), extension (P=0.264), abduction (P=0.077), internal rotation (P=0.972), and external rotation (0.945). A significant difference was found in the Y-balance test in medial (P=0.026) and inferior-lateral directions (P=0.047), but no significant difference in superior-lateral direction (P=0.715) and composite score (P=0.071). Conclusion: Based on the results, it seems that the balance in the dominant arm is better than that in non-dominant arm in the athletes so the non-dominant arm may be at more risk for injury development. We, therefore, recommend that the coaches and trainers pay particular attention to these findings in designing the injury prevention programs.

Rugby is a demanding contact sport. In light of research, poor balance, reduced jumping ability, muscle strength, and incorrect landing patterns might contribute to the increased risk of injury in athletes. Investigating the relationship between tests assessing these abilities might not only allow for the skillful programming of preventive training but also helps in assessing the risk of injury to athletes. Thus, the main purpose of this study was to investigate the relationship between dynamic balance, vertical and horizontal jumps, and jump-landings movement patterns. Thirty-one healthy amateur adolescent rugby players (age: 14.3 ± 1.6 years, height 171.4 ± 9.7 cm, body mass 80 ± 26 kg) participated in the study. Data were collected by the Y-balance Test (YBT), Counter Movement Jump (CMJ), Single Leg Hop for Distance (SLHD), and Landing Error Score System (LESS). Significant positive correlations were found between SLHD both legs (SLHDb) and YBT Composite both legs (COMb) (r = 0.51, p = 0.0037) and between SLHDb and CMJ (r = 0.72, p < 0.0001). A relationship was also observed between the CMJ and YBT COMb test (r = 0.51, p = 0.006). Moderate positive correlations were found between the dominant legs in SLHD and the posterolateral (r = 0.40, p = 0.027), posteromedial (r = 0.43, p = 0.014), and composite (r = 0.48, p = 0.006) directions of the YBT. These results indicate that variables that are dependent on each other can support in the assessment of injury-risk and in enhancing sports performance of young athletes.

Abstract Background The shoulder joint is the most commonly injured joint in CrossFit practitioners, because of the high intensity and loads associated with this sport. Despite the large number of clinical cases, there is a shortage of studies that investigate influence of biomechanical aspects of upper limbs' injuries on CrossFit practitioners. This study hypothesized that there would be a difference in function, strength, and muscle activation between Crossfit practitioners with and without shoulder pain. Methods We divided 79 Crossfit practitioners into two groups according to whether they reported pain (n = 29) or no pain (n = 50) in the shoulder during Crossfit training. Muscle function, strength, and activation were assessed using the Disability Arm, Shoulder and Hand function questionnaire, Upper Quarter Y Balance Test and Closed Kinetic Chain Upper Extremity Stability Test shoulder tests, isometric muscle strength assessment by manual dynamometry and muscle activation by surface electromyography and pain report. Results The function based on questionnaire was associated with pain (p = 0.004). We observed a statistically significant difference between the two groups only in the surface electromyography activity of the lower trapezius, and in the variables of shoulder pain and function (p = 0.038). Conclusion Crossfit practitioners with shoulder pain occurring during training showed good function and stability of the shoulder joint, but there was a reduction in the activation of stabilizing muscles, especially the lower trapezius.

Obesity In Children

AbstractBackgroundChildren with congenital cardiac disease experience challenges in developing healthy patterns of physical activity due to decreased exercise capacity and parental fear and confusion about what is permissible. The purpose of this study was to describe physical activity habits in children 10–14 years of age with congenital cardiac disease and the relationship of those habits to obesity as defined by body mass index.MethodsThis cross-sectional study used self-report measures and clinical data to describe the association between physical activity participation and body mass index in 10- to 14-year-old children with congenital cardiac disease. Further, physical activity levels were compared between children who were overweight or obese and those who were not.ResultsChildren (n = 84; 51 males; 33 females) reported low rates of physical activity compared to reports on healthy children. Only 9.5% were overweight (body mass index between the 85th and 94th percentile), and alarmingly 26% were obese (body mass index at or above the 95th percentile). Physical activity and body mass index were not significantly correlated (r = −0.11, p = 0.45) and there was no significant difference in mean physical activity (t = 0.67) between children who were overweight or obese and those who were not.ConclusionsChildren in this study reported low rates of physical activity and a higher obesity rate than was reported in previous studies. However, the two were not significantly correlated. Further research is indicated to determine the specific factors contributing to obesity and to test interventions to combat obesity in children with congenital cardiac disease.

Context: Core stability is important for preventing injury and improving performance. Although various tests for evaluating core stability have been reported to date, information on their relationship and the effect of gender differences is limited. This study aimed to (1) identify correlations among the 3 core stability tests and to examine the validity of each test and (2) identify gender differences in the test relationship and determine whether gender influenced test selection. Design: Cross-sectional study. Methods: Fifty-one healthy volunteers (27 men and 24 women) participated in the study. The participants underwent the following 3 tests: Sahrmann Core Stability Test (SCST), the lumbar spine motor control tests battery (MCBT), and Y Balance Test (YBT). Each parameter was analyzed according to all parameters and gender using the Spearman rank correlation coefficient. Results: Overall, there was a strong positive correlation between SCST and MCBT and moderate positive correlations between SCST and YBT and between MCBT and YBT. Conversely, gender-specific analyses revealed no significant correlations between YBT and SCST and between YBT and MCBT in women, although significantly strong correlations were found among all tests in men. Conclusion: Although these 3 tests evaluated interrelated functions and may be valid as core stability tests, the results should be carefully interpreted when performing YBT in women.

OBJECTIVE: To examine the sensory performance of static and dynamic balance regulation and the risk of falling in physically active adult and elderly women.METHOD: This is a non-probabilistic and intentional cross-sectional study. Thirty four women (51.90±15.84 years) enrolled in a gym attended. The population evaluated was stratified in age groups: 20-59 years (n=18) and 60 69 years (n=16). The gait was evaluated by the Time Up and Go (TUGs), Time Up and Go manual (TUGm), and Time Up and Go cognitive (TUGc), the balance by the Dynamic Gait Index (DGI) and Body Balance Test (TEC). RESULTS: Student’s t-test showed significant differences between age groups for comorbidities: hearing, vision, vertigo, labyrinthitis (p≤0.05). Comparatively, adult women showed better performance indices than older women in physical tests. According to the standards of the tests, there was no risk of falling for any group. However, regardless of age, a detailed examination of the TEC test showed a deficit in the sensory regulation of the visual, vestibular and somatosensory systems of the static and dynamic balance of fallers and non fallers (p≤0.05). The logistic regression analysis indicated the interoceptive regulation of the dynamic balance as a predictor of fall (p≤0.05). CONCLUSION: Deficits in the vestibular and somatosensory systems gradually potentiate the risk of falls in adult and elderly women, even if they remain physically active.

Context: Rounded shoulder posture is a common problem in the athletic population. Recently Kinesio tape has been utilized to improve balance, proprioception, and posture. However, the literature has been unable to provide definitive answers on the efficacy of Kinesio tape use. Objective: To determine the immediate effect of the limb rotational Kinesio tape application on the dynamic balance and proprioception of the shoulder measured by the Y-Balance Upper Quarter Test (YBT-UQ) in male collegiate athletes. Design: Cross-sectional. Setting: Sports medicine research laboratory.Participants: Nineteen healthy male collegiate National Association of Intercollegiate Athletics athletes (including rodeo, baseball, football, and soccer) with a mean age of 19.8 (1.4) years. Interventions: Subjects were randomized into Kinesio tape and non-Kinesio tape groups. The limb rotational Kinesio tape application was applied to the Kinesio tape group, while the non-Kinesio tape group received no intervention. Each group performed the YBT-UQ, which requires reaching in 3 directions in a push-up position, before and after the randomized intervention on a single day. Main Outcome Measures: The variables of interest included the maximum reach distance in each of the 3 directions and the composite score for both trials between the Kinesio tape and non-Kinesio tape groups. Each score was normalized against the subject’s limb length. Results: No statistically significant improvements in any YBT-UQ scores were observed following either the Kinesio tape or non-Kinesio tape intervention. Conclusions: Applying the limb rotational Kinesio tape technique did not improve immediate YBT-UQ scores in a male collegiate athletic population with rounded shoulder posture. The use of Kinesio tape to improve immediate closed kinetic chain function in male collegiate athletes with rounded shoulder posture cannot be supported.

The Relationship

Context:Ankle-dorsiflexion range of motion has often been measured in the weight-bearing condition in the clinical setting; however, little is known about the relationship between the weight-bearing-lunge test (WBLT) and both ankle kinematics and performance on dynamic postural-control tests.Objective:To examine whether ankle kinematics and performance on the Lower Quarter Y-Balance Test (YBT-LQ) are correlated with results of the WBLT using an inclinometer and tape measure.Design:Cross-sectional.Setting:University motionanalysis laboratory.Participants:30 physically active participants.Interventions:None.Main Outcome Measures:The WBLT was evaluated using an inclinometer and a tape measure. The reach distances in the anterior, posteromedial, and posterolateral directions on the YBT-LQ were normalized by limb length. Ankle dorsiflexion during the YBT-LQ was recorded using a 3-dimensional motion-analysis system. Simple linear regression was used to examine the relationship between the WBLT results and both ankle dorsiflexion and the normalized reach distance in each direction on the YBT-LQ.Results:The WBLT results were significantly correlated with ankle dorsiflexion in all directions on the YBT-LQ (P < .05). A strong correlation was found between the inclinometer measurement of the WBLT and ankle dorsiflexion (r = .74, r2 = .55), whereas the tape-measure results on the WBLT were moderately correlated with ankle dorsiflexion (r = .64, r2 = .40) during the anterior reach on the YBT-LQ. Only the normalized anterior reach distance was significantly correlated with the results for the inclinometer (r = .68, r2 = .46) and the tape measure (r = .64, r2 = .41) on the WBLT.Conclusions:Inclinometer measurements on the WBLT can be an appropriate tool for predicting the amount of ankle dorsiflexion during the YBT-LQ. Furthermore, WBLT should be measured in those who demonstrate poor dynamic balance.
