Clinical Meaningfulness

Context: Musculoskeletal injuries (MSK-Is) are a leading cause of missed duty time and morbidity in the military. Modifiable risk factors for MSK-Is, such as inadequate core stability, poor movement patterns, and dynamic balance deficits, have not been identified in military applicants on entering service. Objective: To establish normative functional movement data using a series of screens in military applicants entering basic training and explore relationships among several movement tests. Design: Cross-sectional study. Setting: Military Entrance Processing Station. Patients or Other Participants: A total of 1714 (1434 male, 280 female) military applicants entering the US Army (n = 546), Navy (n = 414), Air Force (n = 229), or Marine Corps (n = 525). Intervention(s): We conducted the Functional Movement Screen (FMS), Y-Balance Test (YBT), overhead squat (OHS), and Landing Error Scoring System (LESS). Movements were assessed using the scoring convention for each screen. Main Outcome Measure(s): The FMS, YBT, OHS, and LESS scores and associations among the movement screens as well as clinical meaningfulness. Results: A total of 1037 of the 1714 enrolled applicants were screened on the day they left for basic training. Normative means for this population were established: FMS = 14.7 ± 1.8, YBT anterior-reach difference = 3.1 ± 3.0 cm, mean YBT composite differences = 8.0 ± 6.8 cm, mean YBT composite percentage = 90.9% ± 8.3%, OHS errors = 5.0 ± 2.8, and LESS score = 5.7 ± 2.1. Backward regression results revealed that the YBT composite percentage was related to the FMS and OHS scores in males and to the FMS and LESS results in females. However, clinically meaningful relationships between the tests varied for both males and females. Conclusions: Sex-normative values for the FMS, YBT, OHS, and LESS screens were established for US military applicants, and some of the assessments overlapped. Overall, males performed better on the OHS and LESS and achieved a greater YBT composite percentage than females. The regression results revealed movement screen performance relationships that varied by sex and clinical meaningfulness. In future studies, we will determine if performance on any of the screens is associated with MSK-Is in basic trainees.

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.

Test Result

Background: Balance deficits are usually related to medial-lateral instability. BMI could be an important factor to consider as; excess body mass or increased accumulation of adipose tissue can directly impact the postural stability which in return impacts balance. Purpose of the study: To find the correlation between BMI and Balance. Method: Sample consisted of 149 students, out of which 100 (67%) were males and 49 (33%) were females. BMI was calculated and was categorized into groups. Bilateral limb length was measured for normalising the data. Static balance was measured by performing blinded stork test and dynamic balance by performing Y- balance test. Data was analysed using Pearson’s correlation test. Result: There was significant correlation between BMI and static balance of left leg (r=0.713, 95% CI 0.623, 0.784, p=0.01) but on comparison, there was no significant correlation between BMI and static balance of right leg (r=0.0458, 95% CI -0.11, -0.205, p=0.58). It was found that there was no significant correlation between BMI and Left Anterior (r= -0.134, 95% CI -0.289, -0.0274, p= 0.103), Left Posterolateral (r=-0.0775, 95% CI -0.235, 0.0843, p=0.347), Left Posteromedial (r=-0.0903, 95% CI -0.248, -0.0715, p=0.273) respectively. Also, it was found that there was no significant correlation between BMI and Right Anterior (r=-0.236, 95% CI -0.382, -0.0778, p=0.00381), Right Posterolateral (r=-0.193, 95% CI -0.343,-0.0334, p=0.0183), Right Posteromedial (r=-0.126, 95% CI -0.281, -0.0354, p=0.125) respectively. Conclusion: There was significant correlation between BMI and static balance of left leg and no correlation was established between BMI and static balance on right leg and also no correlation was established between BMI and static and dynamic balance for right and left leg.

Objective: This study aims to assess the effect of 12 weeks of core stability exercises on functional movement and balance of women working in hospitals. Methods: Participants were 34 women aged 30-50 years working in Imam Khomeini Hospital in Tehran, Iran. They were randomly divided into two groups of exercise and control. The exercise group performed core stability exercises for 12 weeks. The functional movement was evaluated using the valid Function Movement Screen (FMS) method. The dynamic balance, power, agility, speed and flexibility of subjects were also measured using Y balance test, Sargent Jump Test, agility T-test, 20-meter running test, and seated bending forward test, respectively before and after exercise. Paired T-test was used to examine the difference between pre- and post-test scores of each group. Analysis of Covariance (ANCOVA) was used to determine the effect of intervention on the study variables. Results: Results of ANCOVA showed that 12 weeks of core stability exercises significantly improved functional movement performance, dynamic balance, power, agility, speed and flexibility in women. Conclusion: Core stability exercises can improve the performance of neuromuscular system leading to proper movement of spinal, pelvic and hip joints, proper muscle balance, enhanced proximal stability, functional strength and resulting in decreased injury.

Competition Level

Context: Decreased performance in dynamic balance has previously been associated with a history of ulnar collateral ligament injury in baseball players. Previous research on dynamic balance in soccer players has shown that test performance depends on competition level. However, dynamic balance has yet to be examined in baseball players. Objective: To understand normative values and determine differences in dynamic balance, as measured by the Lower Quarter Y-Balance Test, across competition levels in baseball players. Design: Cross-sectional study. Setting: Preseason physical examinations. Patients or Other Participants: Dynamic balance was measured in 88 high school (HS), 78 collegiate (COL), and 90 professional (PRO) baseball players. Main Outcome Measure(s): All participants completed the Lower Quarter Y-Balance Test using the standard protocol. In unilateral stance, they reached with 1 foot in the anterior, posteromedial, and posterolateral directions. We calculated 1-way analyses of variance to compare performance, composite score, and reach asymmetry for each direction as well as the sum of the asymmetry values (P < .05). Composite score was calculated by averaging the maximum normalized reach scores. Reach asymmetry was determined by calculating bilateral differences in reach ability. Results: In comparison with the HS and COL groups, the PRO players exhibited greater posteromedial (P < .01; effect size index [ESI]HS = 1.06, ESICOL = 0.95) and posterolateral reach (P < .01; ESIHS = 0.82, ESICOL = 0.84) as well as a greater composite score (P < .01; ESIHS = 0.60, ESICOL = 0.87). In contrast, HS baseball players exhibited increased anterior reach (P < .01; ESICOL = 0.60, ESIPRO = 0.39) compared with the COL and PRO cohorts. No significant differences in reach asymmetry were observed among groups. Conclusions: Lower extremity dynamic balance performance differed based on the baseball players' competition level. These baseline data may be helpful in identifying low-performing athletes who might benefit from neuromuscular interventions.

The Relationship

Background: Dynamic balance is essential for pitching motion because pitching kinematics requires whole body coordination. The Star Excursion Balance Test (SEBT) and the Y balance test (YBT) evaluate dynamic balance quantitatively. There are some reports that investigated the relationship between SEBT/YBT and pain in upper and lower extremities, but there is no study among high school baseball pitchers. Hypothesis: Dynamic balance deficiency is associated with shoulder pain among high school baseball pitchers. Study Design: Cross-sectional study. Level of Evidence: Level 4. Methods: A total of 259 male high school pitchers who participated in the preseason medical checkups were included in the study. YBT was used to measure their dynamic balance. The participants completed a questionnaire which asked if they were currently experiencing shoulder pain. Results: Twenty-two pitchers had shoulder pain during the preseason medical checkups. In the YBT, the posterolateral balance while standing with the axis leg as well as the posteromedial and posterolateral balance while standing with the step leg were significantly lower in the pain group than in the nonpain group ( P = 0.05, 0.04, and 0.001, respectively). A logistic regression analysis showed that posterolateral balance when standing with the step leg was an independent risk factor for current shoulder pain ( P = 0.04, odds ratio 0.942, 95% CI 0.892-0.996). Conclusion: The dynamic balance of high school baseball pitchers with shoulder pain was lower than that of participants without shoulder pain. In particular, posterolateral direction with the step leg standing was significantly related to shoulder pain. Clinical Relevance: Among high school baseball pitchers, decreased dynamic balance was related to current shoulder pain. YBT maybe recommended in preseason medical checkups for high school baseball pitchers.

Mediating Role

Context Tactical athletes commonly experience high levels of physical stress, which may increase their risk of musculoskeletal injury. It is critical to understand psychological predictors of functional movement (FM), which may help prevent musculoskeletal injury in this population. Objective To determine the associations of combat and trauma exposure with FM characteristics of male tactical athletes. Secondary objectives were to explore confounding influences of age and physical injury history as well as the mediating role of bodily pain. Design Cross-sectional study. Setting Research laboratory. Patients or Other Participants Eighty-two healthy, male, active-duty US Navy Explosive Ordnance Disposal personnel (age = 34.0 ± 6.7 years). Main Outcome Measure(s) Participants completed measures of combat exposure, trauma exposure, physical injury history, and bodily pain. We assessed FM characteristics (ie, Functional Movement Screen [FMS], Y-Balance Test), from which we derived a composite functional status (CFS) measure. Hypotheses were tested using correlational and multiple regression (causal-steps) models. Results In unadjusted models, trauma exposure was inversely associated with the FMS (P = .005) and CFS (P = .009) scores. In adjusted models, these relationships were robust to the confounding influences of age and physical injury history. Trauma exposure and bodily pain were substantive, independent predictors of FMS and CFS in causal-steps models (all P values < .05), implying additive rather than mediated effects (R2adj = 0.18–0.20). Combat exposure did not predict FM characteristics. Conclusions To our knowledge, this is the first evidence of the influence of trauma exposure on the FM characteristics of male tactical athletes, independent of age, physical injury, and bodily pain. This program of research may help to advance the prevention and treatment of musculoskeletal injuries in the tactical environment.

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.
