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.

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.

Objectives: Ballet dancers may increasingly use plantar sensory feedback to control foot position and movement during dance activities. Balance and joint range of motion (ROM) are important factors in ballet and may be related to plantar sensation in ballet dancers. Data on related functions of female ballet dancers compared to female non-dancing athletes are sparse. The aims of the study were twofold: 1. the relationships between plantar sensitivity and dynamic balance as well as between joint ROM and dynamic balance were determined in experienced female ballet dancers and female non-dancing athletes; and 2. the differences of plantar sensation, joint ROM of the lower limb, and dynamic balance between experienced female ballet dancers and female non-dancing athletes were investigated.Study Design: In this cross-sectional study, 21 subjects (11 experienced female ballet dancers and 10 female non-dancing athletes; median age: 23, range: 11 years; median body height: 1.7 m, range: 0.2 m; median body mass: 59 kg, range: 36 kg) were included. Plantar sensitivity was determined by Semmes-Weinstein monofilaments, active ranges of motion of the hip, knee, and ankle joints were measured using a goniometer and dynamic balance was assessed by the Y-Balance test. Correlations between outcome measures were determined in both groups. Outcome measures were compared between ballet dancers and non-dancing athletes using parametric or non-parametric statistical tests (α = 0.5).Results: For the fifth metatarsal head and the heel, higher correlations between plantar sensitivity and Y-Balance test scores in non-dancing athletes compared to ballet dancers were found. Higher correlations between joint ROM and Y-Balance test scores were determined for certain movements in non-dancing athletes compared to ballet dancers. A significantly lower cutaneous threshold was only found for the fifth metatarsal head in ballet dancers compared to non-ballet dancers (p < 0.05). Range of motion was significantly higher in ballet dancers for almost all movements (p < 0.05). Ballet dancers showed significantly higher normalized scores of the Y-Balance test (p ≤ .001).Conclusions: Results of correlation analyses may indicate that non-dancing athletes increasingly must rely on plantar sensation of the fifth metatarsal head and the heel while maintaining dynamic balance compared to ballet dancers, especially in posterolateral direction of the Y-Balance test. Active joint range of motion of the lower extremity and dynamic balance differ between female ballet dancers and non-dancing athletes. Plantar sensitivity is not different for most of the assessed localizations.

Context: Sport-specific adaptations at the glenohumeral joint could occur in adolescent athletes because they start participating in high-performance sports in early childhood. Objective: To investigate shoulder-rotator strength, internal-rotation (IR) and external-rotation (ER) range of motion (ROM), and acromiohumeral distance (AHD) in asymptomatic adolescent volleyball attackers to determine if they have risk factors for injury. Design: Cross-sectional study. Setting: University laboratory. Participants: Thirty-nine adolescent high school-aged volleyball attackers (22 boys, 17 girls; age = 16.0 ± 1.4 years, height = 179.2 ± 9.0 cm, mass = 67.1 ± 10.9 kg, body mass index = 20.7 ± 2.6 kg/m2). Main Outcome Measure(s): Shoulder IR and ER ROM, total-rotation ROM, glenohumeral IR deficit, AHD, and concentric and eccentric strength of the shoulder internal and external rotators were tested bilaterally. Results: External-rotation ROM was greater (t38 = 4.92, P &lt; .001), but IR ROM (t38 = −8.61, P &lt; .001) and total ROM (t38 = −3.55, P = .01) were less in the dominant shoulder, and 15 athletes had a glenohumeral IR deficit (IR ROM loss &gt; 18°). We observed greater concentric internal-rotator (t38 = 2.89, P = .006) and eccentric external-rotator (t38 = 2.65, P = .01) strength in the dominant than in the nondominant shoulder. The AHD was less in the dominant shoulder (t38 = −3.60, P &lt; .001). Conclusions: Adolescent volleyball attackers demonstrated decreased IR ROM, total ROM, and AHD and increased ER ROM in their dominant shoulder. Therefore, routine screening of adolescent athletes and designing training programs for hazardous adaptive changes could be important in preventing shoulder injuries.

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.

Background. The gait abnormalities were linked to the balance deficits in the previous studies. However, the deviations in the gait parameters in COPD are currently not known. The study aims to compare gait parameters, static and dynamic balance, and risk of falls in COPD with those in non-COPD individuals. Method. Fourty-two patients with COPD aged 45 years and gender-matched control subjects were included in the study. Gait parameters were assessed by Win-Track gait analyzer, the static balance was assessed by posturography, and the dynamic balance was assessed by the time up and go test. The fear of falls was assessed by Falls Efficacy Scale. Results. COPD individuals had decreased static and dynamic balance as assessed by posturography ( p < 0.05 ) and TUG ( p < 0.01 ), respectively. A significant difference in swing duration ( p = 0.004 ) and also increased risk of falls ( p < 0.01 ) was observed in COPD patients as compared to non-COPD individuals. Conclusion. COPD individuals have increased swing duration, reduced static and dynamic balance, and increased fear of falls as compared to non-COPD individuals.

Hip Internal Rotation

Context: The repetitive demands of throwing affect glenohumeral (GH) range of motion (ROM) and strength. Less is known about hip alterations in skeletally immature athletes. Objective: To compare GH and hip ROM and strength between age, position, and side of youth baseball athletes. Design: Cross-sectional study. Setting: Multicenter testing. Patients or Other Participants: Seventy-two healthy baseball athletes. Participants' self-reported characteristics were age group (7−11 years [n = 28] or 12−18 years [n = 44]), position (pitcher [n = 22], position player [n = 47], unreported [n = 3]), and side (throwing or nonthrowing arm, lead or stance leg). Main Outcome Measure(s): Bilateral GH and hip internal- and external-rotation ROM were measured passively and summed for total arc of motion (TAM). Glenohumeral and hip rotation and gluteus medius strength were measured. Analyses included linear mixed models. Results: Glenohumeral internal rotation was less in throwing than in nonthrowing arms (P &lt; .05) except in younger pitchers (P = .86). Compared with older athletes, younger athletes had more GH external rotation (103.3° ± 7.7° versus 97.5° ± 9.4°; P = .002), TAM (156.4° ± 8.7° versus 147.9° ± 10.9°; P = .04), and external rotation in throwing compared with nonthrowing arms (101.9° ± 1.2° versus 97.9° ± 1.1°; P &lt; .001). Glenohumeral TAM was less in throwing than in nonthrowing arms (150.5° ± 2.1° versus 154.9° ± 1.3°; P = .01). Younger athletes had more hip internal rotation (38.9° ± 6.8° versus 31.2° ± 7.5°; P &lt; .001) and TAM (68.4° ± 10.0° versus 60.7° ± 9.8°; P = .001) than older athletes. Lead-leg hip internal-rotation ROM was greater than in the stance leg (34.8° ± 8.9° versus 32.8° ± 7.7°; P = .01). Overall, older players were stronger than younger players (P &lt; .05), and the throwing arm was stronger in internal rotation than the nonthrowing arm (10.12 ± 3.72 lb [4.59 ± 1.69 kg] versus 9.43 ± 3.18 lb [4.28 ± 1.44 kg]; P = .047). Conclusions: Youth baseball athletes had typical GH ROM adaptations of less internal rotation and more external rotation in the throwing versus the nonthrowing arm. Greater ROM in younger athletes may be explained by prepubertal characteristics. We obtained hip-strength values in youth baseball athletes, and as expected, older athletes were stronger.

Background: Asthma is a common chronic respiratory disorder in children and adults worldwide. Inhalers are vital medications that are prescribed to control the disease and reduce its mortality and morbidity. Objectives: This study aimed to assess the knowledge and skills of Medical Students (MSs) and pediatric residents (PRs) in using different inhaler devices (IDs). Methods: This cross-sectional study included 243 MSs and PRs at Shiraz University of Medical Sciences, Iran, from March 2018 to March 2019. The MSs were divided into the senior medical students (SMSs) and junior medical students (JMSs). Data regarding participants’ knowledge on metered dose inhalers (MDIs), dry powder inhalers (DPIs), and nebulizers (NBs) were gathered using questionnaires and a face-to-face interview. Results: Of the 243 participants in the study, 113 (46.5%) were SMSs, 87 (35.8%) were JMSs, and 43 (17.7%) were PRs. The mean age of the participants was 26/20 ± 4/25 years. There was no significant difference between studied groups regarding recognition of MDI device (P = 0.072). PRs were more familiar with the DPIs than MSs (P < 0.001). They also could recognize the NBs better than the MSs (P < 0.001). In terms of using DPIs correctly, PRs executed all the steps better than MSs (P < 0.001) except for the third step which all the participants had the same knowledge (P = 0.13). Regarding correct use of NBs, PRs had better performance compared to MSs (P < 0.001). Conclusions: According to our results, there was an educational vacancy in training MSs regarding using IDs correctly, which can lead to poor compliance in asthmatic patients and deteriorating their lifestyle. The current research supports the need to redesign the educational curriculum of MSs and PRs in Iran to teach them sufficient knowledge and skills about how to use different types of inhalers properly.

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.

Purpose: To analyze the influence of playing 2 consecutive prolonged badminton matches on the shoulder strength and range of motion (ROM) of young players. Methods: Sixteen elite junior badminton players (12 males and 4 females; mean (SD): age 16.2 [0.8] years, body mass 63.5 [6.6] kg, height 173.2 [6.3] cm) participated in a cross-sectional study. Shoulder internal (IR)/external rotation (ER) ROM and IR/ER strength measures were conducted before and after 2 consecutive prolonged (ie, 35 min) matches and 12 hours after the second match. Results: After consecutive matches, IR strength of the dominant side and ER strength of the dominant and nondominant sides (effect size [ES] = 0.20–0.57) were reduced. Shoulder total ROM of the dominant side was decreased (ES = 0.80), while on the nondominant side, IR (ES = 0.66) was also decreased. After 12 hours, results showed decreased values in the IR/ER strength of the dominant side (ES = 0.36–1.00), as well as ER of both dominant and nondominant sides (ES = 0.30–0.59). IR ROM of the nondominant side (ES = 0.69) was also decreased. Conclusion: Present results showed that 2 consecutive matches on the same day with brief rest periods led to significant impairments in shoulder strength and ROM levels. These data can potentially elucidate the need for shoulder-specific training and recovery strategies prior to or during competitions.

Context: Biomechanically, the motions used by baseball and softball pitchers differ greatly; however, the throwing motions of position players in both sports are strikingly similar. Although the adaptations to the dominant limb from overhead throwing have been well documented in baseball athletes, these adaptations have not been clearly identified in softball players. This information is important in order to develop and implement injury-prevention programs specific to decreasing the risk of upper extremity injury in softball athletes. Objective: To compare range-of-motion and humeral-retrotorsion characteristics of collegiate baseball and softball position players and of baseball and softball players to sex-matched controls. Design: Cross-sectional study. Setting: Research laboratories and athletic training rooms at the University of North Carolina at Chapel Hill. Patients or Other Participants: Fifty-three collegiate baseball players, 35 collegiate softball players, 25 male controls (nonoverhead athletes), and 19 female controls (nonoverhead athletes). Intervention(s): Range of motion and humeral retrotorsion were measured using a digital inclinometer and diagnostic ultrasound. Main Outcome Measure(s): Glenohumeral internal-rotation deficit, external-rotation gain, total glenohumeral range of motion, and humeral retrotorsion. Results: Baseball players had greater glenohumeral internal-rotation deficit, total–range-of-motion, and humeral-retrotorsion difference than softball players and male controls. There were no differences between glenohumeral internal-rotation deficit, total–range-of-motion, and humeral-retrotorsion difference in softball players and female controls. Conclusions: Few differences were evident between softball players and female control participants, although range-of-motion and humeral-retrotorsion adaptations were significantly different than baseball players. The throwing motions are similar between softball and baseball, but the athletes adapt to the demands of the sport differently; thus, stretching/strengthening programs designed for baseball may not be the most effective programs for softball athletes.
